Timing clock movement 132-071
The 132-071 has a platform escapement. This means is it has a balance wheel rather than a pendulum. When adjusting the timing lever it pushes or pulls the hairspring on the balance wheel. This manipulates the speed of the balance wheel oscillations and therefore the speed of the time. It is done with the lever that sticks out of the dial face. If moving the lever more to the plus side, it will speed up time.
Why the need to time the 132-071
This lever or arm sticking out of the dial slot is able to move up or down to adjust the timing. The factory had it keep perfect time when the arm was in the middle of this slot. This is intended to stick straight out in the middle of the slot in the dial, in between the + and - symbols. It would not surprising if this moved some in shipping and have to adjust the timing a little. It may be best to adjust this arm and start in the dead center. If the clock is slow, move the arm slightly to the + and do the opposite if it is running fast.
