* These values are nominal since the dimension is not controlled to a tolerance. The "k" dimension should be measured when the hook is
new - this becomes a reference measurement. Subsequent measurements are compared to this reference to make determinations about
hook deformation/stretch. See Section 5-5, “Hooks - Stretch”.

6.0 Maintenance
6.1 For hoist maintenance or storage, comply with the following points.
6.1.1
DANGER
Do not lubricate the friction plate of the mechanical brake.
6.1.2
CAUTION
 Always ensure that lubricant is applied to the load chain,
the top pin, the hook necks, the hook latches and the
select lever. Refer to Section 2.1.4 “Hoist Parts”.
 Do not store the hoist under a load.
 Remove any dirt or water on the hoist.
 Store the hoist in a dry and clean area.
 Possibility of corrosion on components of the hoist
increases for installations where salt air and high
humidity are present. Make frequent and regular
inspections of the hoist’s condition and operation.
 Perform all inspections given in “5.0 Inspection” if
irregularity of the hoist is found after operation
6.2 Disassembly/Assembly
6.2.1 When re-assembling the hoist, refer to parts list figure in Section 8.0 for the proper component placement and orientation.
6.2.2
CAUTION
Load Limiter – Do NOT attempt to disassemble or adjust the
Load Limiter built into the Hand Wheel Assembly. Replace the Hand wheel
as an assembly with a new, factory adjusted part
6.2.3 Gear timing – Installing the Gear #2's with the timing marks "O" oriented as
shown in Figure 6-1.
6.2.4
WARNING
Make certain the no-load end Load Chain is not twisted
when attached to the hoist body. See Section 2-1-4 for attachment point.
