4.3 Operation
1) Face the hand chain wheel side of the hoist.

4.4 Principle and Operation of the Slip Clutch
: IMPROPER chain hoist use could result in death or serious injury. To avoid these hazards:
: NEVER disassemble or attempt to adjust the slip clutch assemby. Any attempt to do so will void
the warranty. Contact your closest Harrington Distributor if service is required.
The standard slip clutch device prevents the hoist from being used to lift damaging loads beyond the rated capacity of
the manual chain hoist. When an applied load exceeds the preset value, the hand chain wheel rotates idly. The
mechanism is a friction clutch system located between the hand chain wheel and the mechanical brake.
