Set up clock in a level position
Attach pendulum (when applicable)
Attach weights (when applicable)Place finger on either side of pendulum and carefully move pendulum 1 inch to one side or the other to start swinging motion.
If clock is level, the ticking of the pendulum will be will be in perfect rhythm from left to right.
If not in perfect rhythm, steps must be taken to relevel clock.
(Example: reposition wall clock by moving the base of clock slightly to the left or right until ticking is in rhythm OR position a pad of paper on corner of the clock.)
Set to correct time
Go forward (only) on minute hand and allow clock to chime and/or strike at each sequence.
A Initial adjustments have been made to correct the fast/slow speed of your clock, but final adjustments must be made at home.
Most pendulums have a BOB on the end of the shaft and a nut below.
Screw nut clockwise to speed up clock
Screw nut counterclockwise to slow clock.
Adjustments are made by raising BOB (to increase speed), or lowering BOB (to decrease speed)
Some clocks have an adjustment nut at end of pendulum
Turn clockwise (increase) to adjust fast
Turn counterclockwise (decrease)to slow down clock.
Some clocks have an adjustment wheel on face of clock and letters are normally printed F (fast) S (slow) and wheel is turned to adjust clock
A General rule of thumb for grandfather clocks is 1 full revolution is ¾ of a minute.
