Problem

Cause and explanation

Remedy

The hoist will not lift 
the load (no clicking 
sound).

Pawl not engaging with ratchet disc; possible 
contamination with dirt or foreign material.

Clean and lubricate the 
pawls and ratchet disc 
assembly.

Pawl spring is damaged.

Replace pawl spring.

Ratchet spring is loose or damaged.

Tighten or replace 
ratchet spring.

Load slips or drifts 
while being lowered. 

Dirt or corrosion or foreign material in hoist 
components.

Inspect and correct 
problem. Keep hoist 
clean and lubricated.

The brake is slipping. Friction discs are worn 
from long term use, or are damaged from 
overloading or misuse.

Replace friction disc. See 
chapter 5. INSPECTION 
for minimum allowable 
thickness. Do not 
overload the hoist.

The load drops the 
instant lowering is 
started.

The braking surface is dirty. During assembly, the 
braking surface must be wiped clean of dirt.

Clean or replace the 
brake assembly.

The braking surface is oily. The braking surface 
must not be allowed to become soiled with 
grease or machine oil because it is a dry type 
brake.

Clean or replace the 
brake assembly.

The hoist will not 
lower the load.

The brake has caught. (Hoist was left under 
loaded condition for an extended period, or was 
shock loaded while in operation.)

Place selector lever in 
DOWN position and pull 
hard on the lever handle 
to re-set the brake. 
Resume operation.

Brake components are corroded or damaged.

Replace damaged 
components; keep hoist 
clean and lubricated.

The chain is tight 
when lifting, even 
without a load. 
(A squeaking noise 
can be heard at 
times.)

Gear teeth are worn from long term use, or for 
not being greased regularly.

Disassemble and replace 
the load gear, gear case 
and side plate.

7. Troubleshooting
   

   

Any maintenance or repair of the lever hoist should be performed by properly

   trained 

personnel.
