Function: The purpose of this limit switch is to prevent the operator from slewing while the lower
boom and second post are on or near the towbar thus preventing accidental damage to it. It does
this by breaking the slew signal from the upper or lower controls while the second post is less
than approximately 1 m above the ground.
Location: The switch is located on the first post boom pivot plate.
Adjustment: To adjust the switch loosen the lever clamping nut and rotate the lever. Tighten the
lever clamping nut. The lever is actuated by the lower boom. as it descends.The Normally
Closed contacts of the switch should open when the lower boom is at an angle such that the bot-
tom of the second post is approx. 1 m above the ground.
