Adjustment 

If a Load Limiter equipped hoist cannot lift rated load, 
or less, then the Load Limiter is not set properly or is 
malfunctioning. The slip torque must be adjusted or 
the Load Limiter must be replaced. 

Precautions 

If the hoist does not operate in the “up” direction while 
the Load Limiter is functioning properly, eliminate 
overload conditions such as greater than rated load, 
anchored load, or obstructed load. 

Only Qualified Persons should attempt to 
disassemble/assemble, repair, or adjust the Load 
Limiter. 

Load Limiters are pre-set from the factory. Do not 
attempt to tighten or loosen the locknut. 

Do not attempt to clean the Load Limiter with cleaning 
solutions. Do not attempt to lubricate the Load Limiter. 

Remove adhered dust or dirt on the Load Limiter using 
a cloth. 

Moisture absorption may degrade the performance of 
the Load Limiter. 

Remove dirt from the unit and keep it at ordinary 
temperature in a dry condition for storage.
