SAFETY NOTES 

FAILURE TO HEED THE FOLLOWING WARNINGS MAY 

RESULT IN SERIOUS INJURY OR DEATH! 

Operators must be trained in the proper, safe operation of the hoist.

Hoists are 

not

 to be used to lift, raise, or move people.  If your task involves lifting or moving

people, you 

must

 use the proper equipment, not this hoist.

Cable anchors on hoists are not designed to hold the rated load of the hoist.  You must keep at
least five (5) wraps of cable on the drum to ensure that the cable doesn't come loose.

Stay clear of suspended loads and of cable under tension.  A broken cable or dropped load can

cause serious injury or death.

Avoid shock loads.  This type of load imposes a strain on the hoist many times the actual weight
of the load and can cause failure of the cable or the hoist.

Make sure that all equipment, including the hoist and cable, are maintained properly.
