Used motor oils contain unknown carcinogenic materials.
TO AVOID HEALTH PROBLEMS:
Never use used motor oils as a chain lubricant. Only use Lubriplate
Bar and Chain Oil 10-R as a lubricant for the load chain.
The hoist normally requires no additional lubrication, except for
periodically lubricating the load chain as indicated above or when
the unit is disassembled for periodic inspections, cleaning or repairs.
The brake is designed to operate dry. Do not use any grease
or lubricant on the braking surfaces. When lubricating parts
adjacent to the brake, do not use an excessive amount of
lubricant which could seep onto the brake surfaces.
Using any grease or lubricant on the braking surfaces will cause
brake slippage and loss of load control which may result in injury
and/or property damage.
TO AVOID INJURY:
Do not use any grease or lubricant on braking surfaces. The brake is
designed to operate dry.
When the hoist is disassembled for periodic inspections, check the
pawl for free movement and apply a light coat of WD-40 (WD-40 Co.)
lubricant to the pawl stud.
When the hoist is disassembled for cleaning or repairs, the following
locations should be lubricated using approximately 1 oz. (29.5mL)
per hoist of Molykote BR-2-S (Dow Corning Corp.) grease or
equivalent—threads of handwheel; gears; liftwheel rollers; gear
bearing rollers; journals of chain guide and dead end pin; sheave
wheel rollers (3 and 5 ton); hook ball bearings (3 and 5 ton); hook
collar journals (3 and 5 ton); dead end stud (3 and 5 ton).
NOTE: To assure extra long life and top performance, be sure
to lubricate the various parts of the hoist using the lubricants
specified above. If desired, these lubricants may be purchased
from CM.

DISASSEMBLY
Two points of caution to be observed in disassembly are:
1. Loose rollers and bearing balls are used in various locations
in the units. Care must be taken so as to not lose or misplace
these since they may drop from the unit as the various parts are
disassembled. The number of rollers or bearing balls used are:

The latch is secured to the hook (upper and lower) by a rivet. To
remove the latch, it is necessary to remove the head of the rivet by
grinding or drilling. For replacement of the latch, refer to paragraph
4 of the Assembly Instructions.
ASSEMBLY
Consideration must be given to the following when assembling the
hoist:
1. Assemble the brake components as shown below. The ratchet
teeth must face as shown and engage the pawl. Do not
lubricate the brake surfaces. The brake operates dry. Assemble
handwheel to pinion shaft and turn handwheel to seat brake
components. Assemble the pinion shaft nut to the shaft until
the nut bottoms. Then back nut off at least one but not more
than two flats. Insert cotter pin and bend ends to secure same.
* 1/2 ton hoist has two pawls 180° apart.
2. The intermediate gears have timing marks (letter “O” stamped
on one tooth). The gears must be assembled with these marks
orientated as shown below.
3. For proper operation, the correct number of rollers must be
installed at the rotating points of the liftwheel, intermediate
gears, hook block sheave (3 and 5 ton) and hoist hanger sheave
(10 ton). Also, on the 3 and 5 ton units, the correct number
of bearing balls must be installed in the hook collar to retain
the hook and insure proper loading. Refer to Disassembly
Instructions above for the number of rollers at these locations.
Applying grease, Molykote BR - 2 - S (Dow Corning Corp.) or
equal EP grease, to the rollers or bearing balls will help hold
them in position during assembly.
