MAINTENANCE

The lever hoist is designed and made to withstand heavy-duty materials handling
operations, but wear and damage are unavoidable after a long period of use and depending
on the place and method of use. This is why we suggest that your company or workshop
adapt a periodic inspection program for the lever hoist.

1. Never leave the lever hoist in a damp environment or damp weather such as rain. Always

store the lever hoist in a dry airy area.

2. Proper lubrication will help lengthen the life of the lever hoist. Before storing, check to see

if the lever hoist is well lubricated. Be especially sure that the moving parts such as gears
and bearings are well lubricated.

LOAD CHAIN 

Load chains worn-out or elongated beyond the permissible dimensions must be replaced at
once. Replace the entire load chain immediately even if one link of the load chain is
extensively worn-out, elongated or damaged.

HOOKS 

If the hook opening is elongated beyond the permissible dimension, the hook is
dangerously deformed and must be replaced at once. No deformation of the hook should
arise when the lever hoist is used and maintained properly.
