MAINTENANCE
HOIST LUBRICATION
NOTE: To assure extra long life and top perfor-
mance, be sure to lubricate the various parts of the
Valustar Hoist using the lubricants specified below.
If desired, these lubricants may be purchased from
CM. Refer to page 22 for information on ordering the
lubricants.
Gears
The Protector™ should operate for the normal life of the hoist
without service. The device has been lubricated and calibrat-
ed at the factory for a specific model of hoist and is not
adjustable or interchangeable.
CAUTION: The Protector™ is to be used with
“Century Lubricants HB-11, #3” grease. Use of any
other grease will damage Protector™ parts or cause
improper operation.
The gears and Protector™ are factory greased and should
not need to be renewed unless the gears have been
removed from the housing and degreased.
CAUTION: Never degrease or attempt to disassem-
ble the Protector™. Degreasing may damage parts
or cause erratic, inconsistent operation. If the
Protector™ has been degreased, it must be replaced
by a factory calibrated device.
If the gears are removed from the housing, wipe the excess
grease off the outside Protector™ surfaces with a soft cloth
and degrease the remaining gears and housings. Upon
reassembly, add 7 oz. of above grease to gears and hous-
ing. Also, coat the spline on the end of the drive shaft with a
molydisulphide lubricant such as “Super Herculon.”
Bearings
All bearings and bushings except the lower hook thrust bear-
ing are prelubricated and require no lubrication. Lubricate
the lower hook thrust bearing at least once a month, using a
heavy cup grease.
Chain Guides, Liftwheel & Lower Sheave Wheel
When the hoist is disassembled for inspection and/or repair,
the chain guides, lower sheave wheel (on double chain units)
and liftwheel must be lubricated with Lubriplate, Bar and
Chain Oil 10-R (Fiske Bros. Refining Co.) prior to reassembly.
Apply sufficient lubricant to obtain run-off and full coverage.
Load Chain
A small amount of lubricant will greatly increase the life of load
chain. Do not allow the chain to run dry. Keep it clean and lubri-
cate at regular intervals with Lubriplate, Bar and Chain Oil 10-R
(Fiske Bros. Refining Co.) or equal lubricant. Normally, weekly
lubrication and cleaning is satisfactory, but under hot and dirty

WARNING
The lubricants used in and recommended for the Valustar
Hoist may contain hazardous materials that mandate specific
handling and disposal procedures.
TO AVOID CONTACT AND CONTAMINATION:
Handle and dispose of lubricants only as directed in applica-
ble material safety data sheets and in accordance with applica-
ble local, state and federal regulations.
conditions, it may be necessary to clean the chain at least once a day
and lubricate it several times between cleanings.
When lubricating the chain, apply sufficient lubricant to obtain natural
run-off and full coverage.
Low Headroom Trolley
CM trackwheel bearings are pre-lubricated and require no lubrica-
tion.
ELECTRIC BRAKE ADJUSTMENT
The correct air gap between armature and field, when brake is not
energized, is 0.035 inch and need not be adjusted until the gap
reaches 0.075 inches. To adjust the brake, proceed as follows:
1. Disconnect hoist from power supply.
2. Remove back frame cover.
3. Before adjusting the gap:
a) back off the stud nuts and examine friction linings and friction
surfaces for excessive wear, scoring or warpage.
b) check shading coils to be sure they are in place and not bro-
ken. A missing or broken shading coil will cause noisy brake
operation.
These symptoms indicate the need for parts replacement.
4. Turn adjusting nuts clockwise gaging the air gap at both ends.
5. Replace cover, reconnect the power and check operation.
EXTERIOR FINISH
The exterior surfaces of the hoist and trolleys have a durable, scratch
resistant baked powder coating. Normally, the exterior surfaces can
be cleaned by wiping with a cloth. However, if the finish is damaged,
compatible touch-up paint can be purchased from CM. Refer to
page 22 for information on ordering the paint.

WARNING
Used motor oils contain known 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.
