HOIST LUBRICATION
NOTE: To assure extra long life and top perfor-
mance, be sure to lubricate the various parts of the
Lodestar Hoist using the lubricants specified below.
If desired, these lubricants may be purchased from
CM. Refer to page 52 for information on ordering the
lubricants.
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 adjustable or interchangedable with other
models.
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™ (627-327 and 627-328) are
packed at assembly with grease and should not need to be
renewed unless the gears have been removed from the hous-
ing 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 housing.
Also, coat the spline on the end of the drive shaft
(627-311) with a molydisulphide lubricant such as “Super
Herculon.”
For Models JJ, LL, RR, RRT, JJ-2, LL-2, RR-2 and RRT-2, see
page 48 for special gearing alignment instructions.
The limit switch gears are of molded nylon and require no
lubrication.
Apply a light film of machine oil to the limit switch shaft
threads (627-220 pages 64 and 65) at least once a year.
On Models RT, RT-2, RRT and RRT-2 suspended from
trolleys, the upper sheave, shackle pin and lug pin must
be periodically lubricated with Lubriplate Bar and Chain
Oil 10-R (Fiske Bros. Refining Co.). Also, apply a light
film of EP Grease (Acheson Colloids Co. Molydag #204,
or equal) to the spherical surfaces of the sheave stud nut
and the sheave stud nut seat.
Bearings
All bearings and bushings except the lower hook thrust
bearing are prelubricated and require no lubrication.
Lubricate the lower hook thrust bearing at least once a
month, using a heavy cup grease.

WARNING
The lubricants used in and recommended for the Lodestar
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 applic-
able local, state and federal regulations.
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 lubricate at regular intervals with Lubriplate,
Bar and Chain Oil 10-R (Fiske Bros. Refining Co.) or equal
lubricant. Normally, weekly lubrication and cleaning is satisfac-
tory, but under hot and dirty 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.
TROLLEY LUBRICATION
Low Headroom Trolley
CM trackwheel bearings are pre-lubricated and require
no lubrication.
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 52 for information
on ordering the paint.
SOLID STATE REVERSE SWITCH
(115-1-60/230-1-60 Units Only)
Above an ambient temperature of 104°F. (40° C.), the fre-
quency of hoist operation should be limited to avoid over-
heating the solid state reverse switch. Even at temperatures
less than 104° F. (40° C.), high duty cycle, frequent starting
or reversing, excessive inching, jogging or plugging may
overheat the solid state reverse switch. Overheating the
switch will cause it to malfunction, and this in turn will over-
heat the motor and/or damage the solid state reverse switch.
If allowed to cool, the solid state will return to normal
operation. However, before returning the hoist to service, the
following procedure should be used to determine if the
switch has been damaged.
1. De-energize the power system supplying the hoist
and remove the solid state reverse switch.
2. Connect the solid state reverse switch to a
115-1-60/230-1-60 light circuit as shown below.

WARNING
Used motor oils contain known carcinogenic materials.
TO AVOID INJURY:
Never use motor oils as a chain lubricant. Only use Lubriplate
Bar and Chain Oil 10-R as a lubricant for the load chain.
