Adjustment
See Figure 5-5 for the following procedure.
Lower the boom onto blocking at ground level and adjust
each limit switch as follows:
1. Adjust spring tension so there is enough force to lift the
weight of the chain and rotate the actuating lever when
the weight is lifted.
2. Loosen the setscrew in the limit switch lever so the lever
is free to rotate.
3. Manually lift the weight to allow the actuating lever to
rotate upward.
4. Hold lever at Dimension A.
5. Hold the roller on the limit switch lever against the
actuating lever while performing step 6
.
6. Turn the limit switch shaft clockwise only enough for
limit switch to click open and hold. Then securely tighten
the setscrew in the limit switch lever.
7. Test the limit switch for proper operation (see
Maintenance); repeat the adjustment steps until the limit
switch operates properly.
