MAINTENANCE

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 applicable
material safety data sheets and in accordance with applicable
local, state and federal regulations.

HOIST LUBRICATION

NOTE: To assure extra long life and top performance, 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 interchangeable 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 housing and degreased.
CAUTION: Never degrease or attempt to disassemble 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.
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 satisfactory, 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.
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.

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 frequency of
hoist operation should be limited to avoid overheating 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 overheat
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.
3. Close the switch to energize the 115-1-60/230-1-60 power
supply. The light bulb will illuminate if the solid state reverse
switch is not damaged. If the bulb fails to illuminate, the switch
is damaged and must be replaced.
4. Turn the 115-1-60/230-1-60 power off and remove the solid
state reverse switch from the test circuit.
Reinstall the solid state reverse switch in the hoist and reconnect
it using the wiring diagram supplied with the hoist. Re-energize the
power system supplying the hoist and test for proper operation.
Also, ventilate the space around the hoist and/or reduced duty cycle,
excessive starting, excessive plugging to reduce future malfunctions
of the solid state reverse due to overheating.
