1. Unpack all of the parts for your mantel clock.  Do not throw away the carton or inside padding.  These could be useful if you ever have to ship your clock again.

2. Access to the clock movement is gained through the back of the clock case.  Carefully remove all protective material so as not to disturb the location of the hammers and gong rods.

3. Lift the chime hammer hold down lever as far as it will go, thus freeing the hammers.

4. Carefully wind the clock fully in a clockwise direction.  Should the clock fail to start immediately after winding, rotate the clock slightly from left to right until it begins to run.  Wind once a week to keep the precision eight day movement at peak efficiency.

5. Set the clock to the correct time by slowly turning the minute (longest) hand in a clockwise direction. 
The chiming mechanism will adjust itself correctly within one hour after setting.  Do not make any adjustments for the first 2-3 days.

 

 

6. Should the clock need adjusting to keep the proper time, locate the time adjusting screw (shown in the picture above) and turn the screw towards the fast or slow with a small jeweler's screw driver.  If your clock has an older "floating balance wheel" as (B) shown in the picture to the left - hold the balance wheel motionless - locate the small adjusting regulator (A).  Rotate the adjusting regulator to the left (-) if the clock is running fast, to the right (+) if the clock is running slow.  Moving the regulator lever 1 hole on the balance wheel equals approximately, 2.5 minutes per day.

 

 

 

7. Do not adjust the chime hammers unless the chime tone is incorrect. 

The chime tone may be affected by the hammers resting on the chime rods or striking the rods off center.  There are different types of chimes (rods, coils and bells).  Chime hammer arms are made of brass and can be safely bent.  If necessary, adjust the hammers so they do not interfere with each other while moving or striking the chime rods, chime coil or chime bell.  This is accomplished by bending the hammer arms slightly in the middle so that each hammer rests approximately 1/8" from each rod or 1/8" from the coil or bell.  DO NOT bend the chime rods or chime coil.  Chime volume cannot be adjusted.

 

 

 


HELPFUL HINTS TO GOOD CLOCK PERFORMANCE

1. The manufactures of most clock movements recommend movement oiling every 2 years and thorough cleaning every 5 to 10 years depending on climatic conditions, by a professional repair center.

2. Avoid conditions of extreme heat or dryness; particularly in winter, to prevent cracking of the clock cabinet.

3. Wax and polish your clock cabinet as frequently as you do your other furniture.  Use a non-silicone liquid or paste wax.

4. When cleaning glass, use a non-ammonia glass cleaner.  Never spray the cleaner directly on the clock.

 

Hanging the clock with a stud. - Now you may hang the clock on the wall. A secure screw coming directly out of the wall works well for this clock.  If a stud behind drywall is available, always use the stud with a screw coming straight out of the stud through the drywall exposing about 1/2 - 3/4 of an inch outside the drywall.

Hanging the clock without a stud.

A zip wall anchor is the easiest, yet strongest way to go. Zip Anchors are the fast way to provide light duty anchors in gypsum wall board (dry wall). Their coarse and wide thread design and self drilling point offer you a very quick and easy installation. Zip anchors are made in both steel and engineered nylon. Use these with #6 and #8 sheet metal or drywall screws. I usually use the nylon type.

To install plastic wall anchors, tap a small hole  smaller than the anchor itself (plastic piece).
With a Phillips head screw driver, screw the anchor into the wall until the head is flush with the wall. Do not over tighten as this will reduce the gripping power of the anchor.
 
Use a screwdriver to screw a metal screw into the plastic anchor until the screw is completely inserted into the anchor and leave about of the screw 3/4" exposed where you will hang your clock. (appropriate screws are usually included with wall anchors when purchased).
