This comprehensive guide is designed to benefit individuals who have the pleasure of owning a beautiful and timeless piece of horological craftsmanship, whether it’s a cherished grandfather clock or an elegant floor clock. Whether you’re a seasoned collector, a new owner, or simply curious about these magnificent timepieces, this resource offers valuable insights and practical advice to help you make the most of your clock.

Locating Your Clock’s Information Label

Your clock’s information label, containing crucial details like the model and serial number, is pivotal for maintenance and part replacements. Upon receiving your Grandfather Clock, we recommend checking the label’s location. It might be on the shipping carton’s exterior, the clock door’s back, the top or back of the Grandfather Clock, inside the top back corner, or above the clock’s dial’s back. This label will come in handy for parts acquisition, maintenance, or repair needs.

The Core Mechanics of a Grandfather Clock

At the heart of every towering timepiece lies its movement, a complex mechanism responsible for critical functions such as managing hourly alerts, maintaining accurate time, and producing melodious chimes. Integral to this process are the pendulum and the weights, both of which are pivotal for the clock’s seamless operation. The pendulum serves as a rhythm regulator, and its adjustments play a pivotal role in ensuring accuracy, as discussed in the given guidelines. The triad of weights, each with a distinct role, governs three essential functions: the left weight controls the hourly alert, the central one manages time progression, and the right weight orchestrates the melodic chimes. It’s imperative to understand that these weights are distinct in nature and positioning them accurately (from left to center to right) is crucial for the clock’s peak performance. Suspended from either chains or cables, these weights need their weekly elevation to keep the clock ticking. For clocks with cable-driven weights, a crank does the job, while those with chain-driven weights rely on a simple pull of the chain. The melodious alerts and chimes are the results of hammers delicately hitting rods of varied lengths, with each rod tuned to produce a unique note. The harmonious chime sequences are achieved by meticulously orchestrating the sequence in which these hammers greet the rods.

Six Steps to Setup Weight-Driven Clocks

STEP 1: PREPARING YOUR CLOCK FOR SETUP

Within the base of the shipping carton, you’ll find a box. Inside this box, you’ll discover:

a) A key tailored for your clock’s door;

b) A crank designed for winding your clock;

c) Weights vital for the clock’s movement. Also, nestled in the shipping carton is the clock’s pendulum, securely packed in a separate box.

Position the clock nearing its designated spot. It’s CRUCIAL to make sure the clock sits squarely and securely on the floor to prevent it from toppling over. Tweak the levelers to ensure optimal stability and correct alignment.

You can access the clock’s movement, chimes, and cables in three ways:

• Through the front doors;
• Via the top side panels (or side doors in some models);
• Through the rear access panel;
• The top side panels are secured from inside with either tape or a plastic clip. You can rotate the plastic clip or permanently remove the tape for accessibility.

Hold the cardboard sleeve at designated points ‘A’ and ‘B’, then pull it downwards in a straight manner. This sleeve is wrapped around the chime rods and pendulum guide. Ensure you pull it directly off the chime rods and pendulum guide ends.

Gently remove the foam pads placed between the chime hammers and chime rods. Exercise caution during this step to prevent any deformation of the chime hammers. Once the cardboard sleeve is off, the chime hammers can move freely, simplifying the foam pads’ removal.

IMPORTANT: DO NOT REMOVE the styrofoam blocks situated above the cable pulleys. This step is pivotal during the setup process. Prematurely taking out these blocks could lead the cables to overlap, thereby potentially obstructing the movement. Only remove these styrofoam blocks when they naturally become loose, which usually happens after about eight (8) hours of operation.

Shift the clock to its designated spot. Once positioned, it’s essential to ensure the clock cabinet is perfectly level, because an uneven alignment may hinder its operation. There are four (4) adjustable levelers, one at each corner beneath the cabinet. You can turn these levelers clockwise (up) or counter-clockwise (down) for fine-tuning. Utilize a leveling tool on the clock cabinet both longitudinally and laterally, tweaking the levelers for a balanced position. Especially if the clock sits on a carpet, it’s advisable to occasionally recheck its level after the initial setup, as it might require readjustments over time.

Make certain the clock stands squarely and sturdily on the floor to prevent any risk of toppling over.

For cases with illumination: Some clock designs feature interior lights. Prior to switching the light on, ensure all packing materials surrounding the bulb have been taken out.

TIP: For the upcoming procedures, we recommend either donning cotton gloves or employing a gentle cloth while managing the components.

STEP 2: SETTING UP THE PENDULUM

Some pendulums come with a colored protective layer on the pendulum disk. Before you hang the pendulum, gently peel off this layer. Find the pendulum guide either through the front door or any side/back panels. With one hand, steady the pendulum guide. Using your other hand, guide the pendulum through the front door. Hook the pendulum onto the pendulum guide through the designated slot, ensuring it hangs stably.

STEP 3: INSTALLING THE WEIGHTS

Before setting up your clock, it’s crucial to leave the styrofoam blocks in place. Only remove them after the clock has been running for a while, typically around eight hours or when you notice they’ve loosened on their own.

Clocks usually come with a set of three weights, each with a unique weight and designated position. When facing the clock, you’ll find labels at the base of the weights indicating their correct hanging spots. Ensuring each weight is in its proper location is essential for the clock’s accurate operation. Before hanging, inspect the weights to confirm they’re assembled securely.

Ensure the cable aligns with the cable pulley before hanging the weights.

STEP 4: ADJUSTING THE LUNAR DIAL (available in certain models)

Gently push on the lunar dial’s front with your fingertips and turn it clockwise until the moon sits right below the #15 mark on the lunar arch, with each mark denoting a lunar day.

Consult a calendar or almanac to find the date of the previous full moon. Count how many days have passed since that full moon.

For each day after the full moon, turn the lunar dial one lunar day clockwise.

For instance, if it’s been 3 days since the last full moon, adjust the lunar dial 3 days forward, positioning the moon at the 18th lunar day mark.

As long as the clock runs uninterrupted, the lunar dial will reflect accurate moon phases. Should the clock halt, the lunar dial stops as well, but can be reset once the clock restarts.

If you encounter issues adjusting the lunar dial, consult the Troubleshooting Section.

STEP 5: ADJUSTING THE TIME (Handling the Hands)

NOTE FOR CLOCKS WITH AUTO CHIME SEQUENCING: Ensure the chime selector is not set to “Auto” when adjusting the hands. Altering the hands’ direction while the auto chime feature is active could harm the chime system.

NOTE FOR CLOCKS WITH DAY/NIGHT SHUT-OFF: Keep the Day/Night lever in the strike position (fully upwards) while adjusting the hands. To set the correct time, only move the MINUTE HAND in a counterclockwise direction. This will automatically adjust the hour and minute hands to the desired time.

Refrain from adjusting the HOUR HAND. It will shift on its own as you move the minute hand. The advantage of moving the minute hand counterclockwise is that you won’t have to wait for the chimes every quarter hour. The clock mechanism self-adjusts to synchronize the chimes with the set time. If the chimes don’t align post-adjustment, allow the clock to run for 2 hours for self-correction.

STEP 6: INITIATING CLOCK OPERATION

Access the clock’s interior through its front door and gently hold the pendulum disk’s side.

Shift the pendulum towards the far left from its central position and release it. Allow the clock to function for a short while until the pendulum establishes a steady swing rhythm.

Should your clock deviate from the accurate time within a 24-hour span, consult the General Information Section for guidance on calibrating its timekeeping.

Once the styrofoam blocks loosen, which is common after about eight hours of consistent operation, they can be safely removed. To do so, lift the blocks vertically until they’re free from the cable pulley. Then, gently guide them backward, ensuring they pass through the cables. Refrain from using tools for this process and ensure the cable remains untangled and does not coil on the drum.

Six Essential Steps to Install Chain-Suspended Weight Clocks

STEP 1: CLOCK SETUP GUIDE

When you open the bottom of your shipping carton, you’ll find a box containing:

• A key tailored for your clock door;
• Weights responsible for the clock’s movement.

In addition to these, the pendulum for your clock is carefully packed in a distinct cardboard box within the shipping carton.

Before starting, position your clock near its intended final spot. 

ALERT: Always ensure that the clock is stably set and squarely placed on the ground to prevent any potential mishaps. For optimal stability and alignment, tweak the levelers as needed.

To access the clock’s internals – its movement, chimes, and chains – you have three options: via the front door(s), side, or the rear panel. The rear panel is attached using plastic clips; rotate the top clips to detach it. Side panels are held in place either by tape or a plastic clip which can be removed. For a comprehensive guide on detaching and attaching side panels, consult the General Information section.

For the chime rods, gently slide off the plastic retainer. Also, make sure to take out the foam pads placed between the hammers and chime rods. Exercise caution during this step to avoid damaging the chime hammers and rods. You will find the chains safely stored in a bag near the clock’s movement. Gently free the bag and sever the connecting string with scissors, letting the chains dangle. 

CAUTION: As you proceed, ensure you don’t inadvertently yank the chains through the movement or off their sprockets. To release the chains, slide down the plastic retainer off of them. To finish, detach the spring clip from the movement’s back by freeing one end .

Once you’re ready, finalize the clock’s placement. A vital step is ensuring that your clock’s cabinet is perfectly level; an uneven cabinet might disrupt the clock’s operation. Four adjustable levelers are positioned beneath the cabinet at every corner. Using a level, confirm the clock’s alignment both horizontally and vertically, and make necessary adjustments using the levelers. Given that the clock may settle over time, especially if placed on a carpet, you should revisit its alignment post the initial setup. Always ascertain that the clock stands firm and square on the floor, minimizing any risk of it toppling.

For those with illuminated clock cases: Some models come with an internal light feature. Prior to using this, gently remove the paper sheath from around the light bulb.

PRO TIP: When handling clock components, we recommend either wearing soft cotton gloves or using a delicate cloth to ensure the parts remain unblemished.

STEP 2: INSTALLING THE PENDULUM

Some pendulums come with a protective color film over the disc. Before setting up, ensure you gently peel off this film. To place the pendulum, identify the pendulum guide either through the main front door or side/back panels. Using one hand, hold onto the pendulum guide. With your other hand, guide the pendulum through the front and hook it onto the pendulum guide. Ensure it’s securely hanging in place.

STEP 3: POSITIONING THE WEIGHTS

Typically, clocks incorporate three distinct weights. When viewing your clock head-on, each weight has an indicator at its base denoting its appropriate hanging spot. Each weight varies slightly in its mass, and it’s imperative that EACH WEIGHT IS POSITIONED ACCURATELY for the seamless operation of the clock. As a precautionary step, inspect the weights to confirm they are snugly assembled.

WARNING: It’s crucial to make sure each chain link sits perfectly on the sprocket’s teeth. Always hang the weights using the sturdy hook at the chain’s end, and not by the chain links themselves.

STEP 4: ADJUSTING THE MOON DIAL (Available for specific models)

Using your fingertips, gently press on the moon dial’s front and twist it clockwise till the moon icon aligns just below the lunar day #15 marker on the lunar arch. To calibrate it further, consult an almanac or calendar to find the last full moon’s date and tally the days since. Adjust the moon dial clockwise by one lunar day for every day post the recent full moon. For instance, if it’s been three days since the last full moon, adjust the moon dial three lunar days forward so that it aligns with the lunar day 18 marker.

Once calibrated, the moon dial will showcase accurate moon phases as long as the clock remains functional. However, if the clock halts, the moon dial will cease too. In such cases, it can be re-adjusted upon restarting the clock.

For issues with the moon dial not turning, consult the Troubleshooting Section.

STEP 5: TIME ADJUSTMENT (Manipulating the hands)

To adjust the time, guide ONLY THE MINUTE HAND in a counterclockwise direction until both the hour and minute hands align with the desired time.

REFRAIN FROM ALTERING THE HOUR HAND. It will automatically adjust as the minute hand is maneuvered. By directing the minute hand counterclockwise, there’s no need to pause for the clock’s chime each quarter hour. The mechanism is equipped with a self-regulation feature that aligns the chimes with the current time. Should the chimes be off post-adjustment, allow the clock to function for an additional 2 hours to self-correct.

STEP 6: INITIATING CLOCK OPERATION

Gently access the pendulum disk through the clock’s front door.

Guide the pendulum towards the extreme left and release. Give the clock a few minutes to stabilize, allowing the pendulum to adopt a consistent swing rhythm.

Should your clock drift in its timekeeping after a 24-hour period, kindly consult the General Information Section for guidance on calibrating its accuracy.

Core Information

PRODUCT IDENTIFICATION DETAILS

The identification details of the product include the clock’s model and serial numbers. These numbers are crucial when seeking parts or services. This identification label can be found in various spots: on the shipping carton’s exterior, behind the clock door, the clock’s back or top, the upper rear corner inside the clock, or above the clock’s dial backside. Always refer to this label when reaching out to us or the respective dealer.

RELOCATING YOUR TIMEPIECE

When relocating your timepiece, it’s imperative to handle it with care. Ensure accessories like the pendulum and weights are safely removed and packed to avoid potential damages. A vital reminder: Always refrain from winding a cable-driven mechanism without its weights.

DETACHING/ATTACHING THE UPPER SIDE PANELS OF THE CLOCK

Your timepiece may come with wooden or glass upper side panels, providing access to the clock’s mechanism and chime regions. These panels might be secured with tape or a plastic fastener during transit. To detach a panel, access it via the front door and either twist the plastic fastener or peel off the tape. Proceed with the following steps:

• Gently hold the wooden slats or handle using your fingertips. Ensure you don’t exert force on the grill cloth or glass to avoid detaching it from the wooden upper side panel;
• Elevate the upper side panel; it sits within a groove at its lower edge;
• Push the panel’s lower edge towards the clock’s center and simultaneously drag the top edge downwards, out of the upper groove;
• Angle the upper edge of the panel towards the clock’s core;
• Extract the upper side panel from its frame, starting with the bottom end.

CHARACTERISTICS OF GLASS

It’s worth noting that during the processes of forming glass – like heat bending, cutting, or polishing – there can be minor marks. These marks are perceptible and are intrinsic to the glass-making process. They aren’t deemed defects. For cleaning purposes, utilize a glass cleaner that’s free from ammonia. Remember to avoid spraying the cleaner directly onto the clock.

WEIGHT MAINTENANCE

For the smooth operation of your clock, ensure the weights are raised every week; if neglected, the clock will cease to function.

FLOOR CLOCKS WITH CABLES AND PULLEYS

Weights hanging via cables and pulleys should be lifted using the designated crank. Refrain from manually holding the weights during the cranking process. Insert the crank into the holes present on the dial face and rotate the crank in a counterclockwise direction to elevate the weights.

FLOOR CLOCKS WITH CHAINS

It’s crucial to pull the chain vertically downwards. Avoid exerting upward pressure on the weights as it might lead to their detachment from the chains. Gently pull the free section of the chain until the weight is about 2 inches away from the wooden board supporting the movement.

TIME ADJUSTMENTS

Modifying the pace of timekeeping is achieved by altering the position of the pendulum disk. This repositioning is done by adjusting the nut. To decelerate the clock, descend the pendulum disk by rotating the nut leftward. Conversely, for hastening the clock, elevate the pendulum disk by turning the nut rightward.

Starting Off: Day One

• Choose a consistent time slot for the next six days to observe and adjust your clock;
• Record your chosen time: ________________________________;
• Cross-verify the current time;
• Adjust the minute hand to align with the exact current time.

Days Two through Six (Adjustments as Needed)

• Confirm the current accurate time;
• Compare the displayed time on your clock with the real-time. Determine if your clock is running ahead or lagging;
• Adjust the pendulum using its nut. A full turn adjusts the clock by about 30 seconds over a day. Every pendulum may have a slightly different adjustment rate;
• Reconfirm the current time;
• Readjust the minute hand to reflect the precise current time.

Nighttime Auto-Mute (Available in Certain Models)

Some clocks have an auto-mute feature, silencing the chimes between 10:15 p.m. and 7:15 a.m. To activate this, use the left side dial lever.

If your clock doesn’t chime between 10:15 a.m. and 7:15 p.m., re-adjust the clock hands by 12 hours. First, deactivate the auto-mute, then rotate only the minute hand counter-clockwise to set the accurate time.

Illuminated Interiors (For Specific Models)

Certain clocks come with internal lighting. Ensure you remove the protective paper cover from the bulb before turning on the light.

Chime Preferences

Change your clock’s chime melody via its selection lever.

• Some clocks only play the Westminster chime;
• Others offer a trio of tunes;
• A few models auto-rotate the chime every hour. Use the selector lever to enable this or pick a specific melody.

For a clock with only the “Chime-Silent” label, you’ll get the Westminster chime. If your clock supports multiple chimes, the lever will list the choices.

All standard floor clocks come with the Big Ben hourly gong. Refrain from adjusting the chime lever during an ongoing chime—it can damage the system.

Looking After Your Clock

Your clock is designed for minimal upkeep, but a few steps can ensure its lasting quality:

• Remember to wind the clock once a week;
• Always keep the door securely fastened;
• Regularly clean and shine the clock’s exterior, treating it like any other piece of furniture. Opt for a non-silicone-based wax, either in liquid or paste form;
• Protect the clock from direct sunlight, excessive temperature shifts, and drastic humidity changes. Continuous exposure to sunlight can lead to fading, while harsh temperatures and humidity can warp or crack the wood;
• Periodically verify that the clock stands stable on all its four supports, especially during the initial months on a carpet. Over time, the clock might settle into the carpet, potentially causing imbalance. If needed, adjust any of the four supports;
• From time to time, inspect the weights to make sure they remain securely attached;
• We advise having your clock mechanism lubricated every two years from its purchase date. Additionally, a comprehensive cleaning every five to ten years is recommended, although environmental factors like extreme temperatures, humidity, or salt in the air might require more frequent maintenance. For such servicing, rely on professionals. Reach out to an Authorized Service Center rather than attempting it yourself.

Solving Common Issues

Before diving into troubleshooting, ensure you’ve carefully followed all accompanying product instructions. They contain comprehensive details that can address most concerns.

Moon Dial Rotation Issues

Should you find the moon dial unresponsive (as outlined in set-up STEP 4), it could signify the engagement of gears that automatically adjust the moon dial. To resolve:

Turn the minute hand back 3-1/2 hours as instructed in STEP 5.

Adjust the moon dial.

Proceed to set the time following STEP 6.

Chime Timing Misalignment

In cases where the chime rings more than a minute early or late, the minute hand might need adjustment.

Note: Be cautious to avoid scratching the hand nut, hand, or dial.

Steps:

• As soon as the chime begins, halt the pendulum and note down the time;
• Using pliers, gently unscrew the small nut anchoring the minute hand by turning it anticlockwise. Simultaneously, stabilize the minute hand close to the nut with your fingers;
• Pull the minute hand directly off its shaft. It isn’t screwed in and should detach smoothly. On its rear side, the minute hand has a small protrusion around its hole, known as the hand bushing. Grip this bushing securely with pliers, ensuring it doesn’t slip. Adjust the clock hand either forwards or backwards to align with the correct chime timing;
• Attach the hand back onto the shaft, ensuring it points accurately to the time noted earlier, accounting for any modifications made in the previous step. If not aligned properly, revisit steps 2 and 3;
• Tighten the hand nut using pliers, but avoid excessive force;
• Restart the pendulum;
• Adjust the time by only moving the MINUTE HAND in a reverse direction, as highlighted in set-up STEP 5.

Scenario: Clock rings at 1:10 but should do so at 1:15.

• Halt the pendulum as the clock chimes at 1:10 and jot down this time;
• Gently unscrew and remove the small nut;
• Detach the minute hand. Securely hold the bushing’s sides and adjust the hand forward by 5 minutes;
• Reconnect the hand ensuring it points to 1:15. Tighten the hand nut moderately;
• Ensure the hand nut is secure;
• Reactivate the pendulum;
• Readjust the clock to the current time.

Clock Hourly Strike Misalignment

If your clock doesn’t strike accurately after several hours, adjust ONLY the HOUR HAND. Move it forward or backward to synchronize with the number of hour strikes. This won’t harm the clock. To adjust the minute hand, move it anticlockwise as detailed in Step 5: Time Setting.

Clock Fails to Chime or Strike

• Ensure the selector lever isn’t set to “silent” or stuck between chime tunes;
• Clear any packing remnants from the movement region;
• Ensure weights hang in their designated positions. Verify by checking the labels underneath each weight;
• For models with nighttime muting, ensure it’s not activated (Refer to AUTOMATIC NIGHTTIME SHUT OFF in General Info);
• Adjust hammer for accurate chime tone, if necessary;
• Change the chime tune or set it to “silent”;
• Styrofoam blocks might restrict cable movement above the pulleys. Lift them directly until they’re clear of the pulley, then push them past the cables. Don’t use instruments to do this and avoid cable overlap on the drum.

Inaccurate Chime Tone

Avoid adjusting chime hammers unless the tone is off. Hammer setting can impact the tone, especially if they rest on or strike chime rods off-center. Although factory-set, they may require adjustments. Most clocks don’t need hammer adjustments. Identify your chime type (rods or tubes) and follow the guidance below.

For CHIME RODS: The hammer arms are brass-made and can be bent safely. Adjust hammers to prevent mutual interference during motion or striking. Bend the arms slightly so each hammer is about 1/8” away from each rod. Never bend the rods. Chime volume adjustments aren’t possible for a chime rod movement.

Chime Tube hammer arms are constructed from spring steel. It’s crucial NOT to bend these arms. The purity of the chime’s sound is influenced by the gap between the hammer and the chime tube, usually set at approximately 1/16”. This gap can be modified by either loosening or tightening the thumb screw linked to the hammer’s string. Be cautious: Excessive tension or an overtightened string can disrupt the chime sequence.

Please remember: The hammer’s tension screw is pre-set at the factory and is NOT meant for adjustments.

Uneven Weight Descent

If the automatic nighttime shutoff or the “silent” feature (available on specific models) is activated, you may observe that the center weight descends more rapidly compared to the other weights.
