1. Loosen, but do not remove the two (2) jam nuts on the proximity switch
body.
2. Check the gap between switch and boom. The gap must be within the
range specified in Fig. 10-9.
3. If the boom extension proximity light does not illuminate when the
boom is extended to the specified distance (approximately 21 feet with
a tilting tower or 25 feet with a standard carriage), adjust the proximity
switch to slightly reduce the gap. Do not exceed gap tolerances
specified in Fig. 10-9. Snug jam nuts to hold switch in position.
4. Extend the boom and check operation of the boom extension proximity
light. The light must come on when the boom is extended to specified
distance (approximately 21 feet with tilting tower or 25 feet with
standard carriage). If the light does not illuminate, stop and retract the
boom. Repeat Step 3.
5. Tighten the jam nuts.
