4) Put a load equal to the desired actuation point on the hoist's hook (do not exceed 125% of the hoist's
rated capacity). Begin to slowly lift the load, then increase the lifting speed. Return the load to its
resting position so the load chain is not under tension.
5) If the load limiter prevents lifting, turn the adjustment screw IN one full turn.
6) Repeat steps 4 and 5 until the load limiter allows lifting.
7) Turn the adjustment screw OUT ¾ of a turn.
8) Attempt to lift the rated capacity load again, beginning slowly, then increasing the lifting speed.
9) If the load limiter does not allow lifting, then turn the adjustment screw IN ¼ turn.
10) Repeat steps 8 and 9 until the load limiter allows lifting.
11) Turn the adjustment screw IN ¼ turn. Then, while holding the adjustment screw, tighten the lock nut to
secure the setting.
