LOAD CHAIN

Clean and Inspection First clean the load chain with a non-acid or
non-caustic type solvent. Then slack the chain and make a link-by-
link inspection for nicks, gouges, twisted links and excessive wear or
stretching. Chain should be gaged throughout its entire length and
replaced if worn beyond serviceable limits.
Gaging Load Chain Wear
To determine if load chain should be continued in service, check
gage lengths as indicated in Figure 15. Chain worn beyond length
indicated, nicked, gouged or twisted should be replaced before
returning hoist to service. Chain should be clean, free of twists and
pulled taut before measuring.
To aid in gaging load chain wear. A chain gage can be obtained from
CM. This can be obtained by ordering chain gage Part No. 3191.
Note that worn chain can be an indication of worn hoist
components. For this reason, the hoist's chain guides, hook
blocks and liftwheel should be examined for wear and replaced as
necessary when replacing worn chain.
Also, these chains are specially heat treated and hardened and
should never be repaired.

Using other than CM supplied load chain may cause the chain to jam
in the hoist and/or allow the chain to break and the load to drop.
TO AVOID INJURY:
Due to size requirements and physical properties, use only CM
HoistAloy load chain in the Lodestar Hoists.
IMPORTANT: Do not use replaced chain for other purposes such
as lifting or pulling. Load chain may break suddenly without
visual deformation. For this reason, cut worn chain into short
lengths to prevent use after disposal.

PROTECTOR

The Protector should operate for the normal life of the hoist without
service. The device has been lubricated and calibrated at the factory
for a specific model of Lodestar Hoist and is not to adjustable or
interchangeable with other models. For proper overload protection,
be sure before installing a Protector that it is correct for the unit. The
edge of the spring washer of the Protector has been color coded at
the factory as follows:

Removing the snap ring on the Protector assembly will allow the
parts to spring apart.
TO AVOID INJURY:
Do not attempt to disassemble the Protector.
