7.5 Load Sheave Inspection
7.5.1 Perform this inspection by removing the chain separator and viewing the load sheave while operating
the hoist slowly, with no load, and in accordance with
Section 4 “Operation”. Refer to Figure 7-8 and
remove the chain separator as follows.
 TCR3000 and TCR6000-2: The chain separator can be removed by removing the shaft retaining
ring from its groove on the limit lever shaft adjacent to the valve section, sliding the limit lever
assembly away from the chain separator, and removing the two larger outboard hex socket screws
holding the chain separator to the hoist body.
 TCR250 through TCR2000-2: The chain separator can be removed by removing the shaft
retaining ring from its groove on the limit lever shaft adjacent to the valve section, sliding the limit
lever assembly away from the chain separator, removing the limit lever from the limit lever shaft,
and removing the hex socket screws holding the chain separator to the hoist body.

7.6 Storage
7.6.1 Whenever the hoist is to be placed into storage, place extra lubricating oil into the air inlet opening and
circulate the air motor before plugging the inlet. Make certain that no debris, dirt or moisture is allowed
to enter the air hoist through air inlet opening during preparations for storage.
7.6.2 The storage location should be clean and dry.
7.7 Outdoor Installation
7.7.1 For hoist installations that are outdoors, the hoist should be covered when not in use.
7.7.2 In order to prevent internal corrosion from occurring, the hoist must be operated using proper quality air
at least once per week by raising and lowering the hoist one full cycle. Note: the possibility of corrosion
in the valve section of the hoist increases for areas where salt air and high humidity are present. For
such situations you may need to operate your hoist more often than once per week.
