WARNING
!
Always wear safety glasses and other appropriate protective equipment during the following
procedures. Use the correct tools for the operations being performed.
Periodic Routine Maintenance Procedure
1. After properly inspecting the hoist, check operation of the hoist thoroughly by lifting and lowering a minimum
of 500 lbs (rated load preferred). Lifting and lowering operations should be checked by operating the hoist in
the two positions of operation, that is, using both downward and upward strokes to lift and lower the test load.
2. After load testing, thoroughly examine the exterior hoist parts for damage. Check hooks for bending or
"opening" caused by incorrectly loading the hook tip or jamming the housing out of line during loading—replace
if bent or opened. For swivel hook models, inspect bearings for wear. On all models check all castings for wear,
taking corrective measures if necessary.
3. Disassemble Handle Sub-Assembly of hoist carefully (refer to disassembly instructions and exploded view of
hoist components on pages 15-25 if needed). Wash all parts in a suitable cleaner, remove all oxides and foreign
material. Examine mechanism for damaged or excessively worn parts, refer to the accompanying photographs
for typical examples. Replace all parts showing evidence of excessive wear or indications of damages.
Particular attention should be given to the following areas:

It is recommended that the user establish a timeline for the routine inspection, repair, and testing of this hoist.
At a minimum, routine maintenance should be performed annually. More frequent maintenance may be necessary
as determined by the user based upon environmental factors, handling, usage, and the age of the hoist.
