How to setup a grandfather clock
At the heart of every floor clock is the movement. The movement controls the hour strike, time keeping, and chime. The pendulum and weights are critical components to operation of the clock movement.
The pendulum provides the ability to regulate and adjust the time keeping. As described within these instructions, adjustments to the pendulum to achieve accurate time keeping is easily accomplished.
The three weights provide power to the hour strike (left weight), time (center weight), and chime melody (right weight). Without these weights, the clock would not operate. Each weight is different and must be properly hung from the movement (left, center, right) to ensure proper operation. Weights are hung from the movement by a cable or chain. The weights must be raised at least every 7 days or the clock will stop.
Raising cable driven weights is accomplished through use of a crank. Raising chain driven weights is accomplished by pulling down on the loose end of the chain.
The strike and chime sounds are made by a series of hammers hitting various length rods. Each rod makes a different sound when hit by a hammer. Specific chime melodies are achieved by controlling the sequence that each hammer hits a corresponding rod.
- Please take a moment to record the clock model number and serial number in the space provided in the Service Information section on page 12.
- The product information label lists the clock model number and serial number. The clock model number and serial number are essential for obtaining parts or service. The product information label may be located in several locations: outside the shipping carton, back of door, back of the clock, top of the clock, inside the top back corner of the clock, or inside the clock above the back of the dial. Refer to this label when contacting your dealer or Howard Miller.
- Attach your sales receipt to this manual for future reference, and record the information from the Product Information Label, as indicated on page 7.
- Please keep any original packing that came with your floor clock
FOLLOW THESE SIX STEPS TO SET UP CLOCKS THAT REQUIRE WEIGHTS SUSPENDED FROM A PULLEY AND CABLE
SETTING UP YOUR CLOCK
Located in the bottom of the shipping carton will be a box. This box contains:
a) a key to fit your clock door, b) a crank which will be used to wind your clock and, c) weights which operate the clock movement. Also, within the shipping carton will be the clock pendulum
packaged in a separate box.
WARNING: KEEP PLASTIC BAGS AND SMALL PARTS AWAY FROM CHILDREN.
Move the clock close to its final location.
WARNING: ENSURE CLOCK IS POSITIONED SQUARE AND FIRM ON THE FLOOR SO THAT IT WILL NOT FALL OVER. ADJUST LEVELERS FOR MAXIMUM STABILITY AND PROPER ALIGNMENT.
Access to the clock movement, chimes and cables is made in three possible ways; through the front door(s), through the top side panels (or side doors on some clocks), or through the back access panel. The top side panels are held from the inside by tape or a plastic clip. The plastic clip may be turned or tape may be removed permanently. Refer to the General Information section on page 7 for proper instructions to remove and install top side panels.
Remove the cardboard sleeve, from around the chime rods and pendulum guide, by holding the cardboard sleeve at points ‘A’ and ‘B’ and pulling straight down. Pull straight down and off the ends of the chime rods and pendulum guide. (See figure 1).
Remove the foam pads from between the chime hammers and chime rods. Care should be taken to avoid bending the chime hammers. The chime hammers will be free to move after the cardboard sleeve has been removed, thereby allowing easy removal of the foam pads.
DO NOT REMOVE THE STYROFOAM BLOCKS from above the cable pulleys. This is
one of the most critical points in the entire set-up operation. Removing the styrofoam blocks at this time could cause the cables to overlap and bind the movement. You can remove the styrofoam blocks AFTER they become loose through normal operation, which typically occurs after eight (8) hours of run time.
Position the clock into its final location. Once in place, your clock cabinet must be leveled, as the clock may not operate if it is not level. There are four (4) levelers under the cabinet on each
corner that can be screwed in (up) or out (down) to make adjustments. Place a level alongside the clock cabinet from front to back and side to side,
adjusting the levelers until level. It may be necessary to periodically check your cabinet after initial set-up, (especially if the clock is on carpet), as it
might settle after original leveling. (see
figure 2). Ensure clock is positioned square and firm on the floor so that it will not fall over.
Illuminated cases: Some clocks have lights illuminating the inside of the clock case. Check that all packaging materials have been removed from the light bulb before operating the light.
NOTE: To perform the following steps Howard Miller suggests wearing cotton gloves or using a soft cloth when handling parts.
Some pendulums have a colored protective plastic film covering the pendulum disk. Carefully remove this film before hanging the pendulum. To hang the pendulum, locate the pendulum guide through the front door, or any of the side or back access panel locations. While holding the pendulum guide with one hand, slip the pendulum in through the front door with your other hand. Place the pendulum hook over the pin or through the slot on the pendulum guide, and lower the pendulum until it is hanging securely on the pendulum guide. (See figure 3).
