MAINTENANCE
LOAD LIMITER
The load limiter should operate for the normal life of the hoist without
service. The device has been calibrated at the factory for a specific
model of hoist. For proper overload protection, be sure before
installing a load limiter that it is correct for the unit.

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

GEARS
NOTE: To assure extra-long life and top performance, be sure to
lubricate the various parts of the Lodestar Hoist using the lubricants
specified. If desired, these lubricants may be purchased from CM.
See online Parts list for required lubricants..
The gearbox is packed at assembly with grease and should not
need to be renewed unless the gears have been removed from the
housing and degreased.
If the gears are removed from the housing, wipe off the excess
grease with a soft cloth and degrease the gears and housings. Upon
reassembly, add grease to gears and housing.
Models A to H hoists require 7 fl. oz. of grease.
Models J-RT require 15 fl. oz. of grease.
BEARINGS
All bearings and bushings, except the lower hook thrust bearing,
are pre-lubricated and require no lubrication. The lower hook thrust
bearing should be lubricated at least once a month.
CHAIN GUIDES, LIFTWHEEL AND LOWER SHEAVE WHEEL
When the hoist is disassembled for inspection and/or repair, the
chain guides, lower sheave wheel (on double- and triple-chain units),
upper sheave wheel (on triple-chain units) and liftwheel must be
lubricated with Lubriplate
Bar and Chain Oil 10-R (Fiske Brothers
®
Refining Co.) or equivalent prior to reassembly. The lubricant must
be applied in sufficient quantity to obtain natural runoff and full
coverage of these parts.

LOAD CHAIN
A small amount of lubricant will greatly increase the life of the load
chain. Do not allow the chain to run dry.
Keep the chain clean and lubricate it at regular intervals with
Lubriplate Bar and Chain Oil 10-R (Fiske Brothers Refining Co.) or
equivalent. 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 runoff and full coverage, especially in the interlink area.
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.

TROLLEY LUBRICATION

See appropriate trolley manual.

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 17 for information on ordering the paint.

TEMPERATURE RATING

Normal ambient operating temperature, unless otherwise specified,
ranges from 0°F to 104°F (-17 to 40°C). Contact factory for ambient
temperature solutions outside this stated range.

BRAKE ADJUSTMENTS

DC ELECTRIC BRAKE ASSEMBLY
The correct air gap between field and armature is 0.008-0.018 inches
(0.2-0.45 mm) for models A through H and 0.008-0.020 inches
(0.2-0.5 mm) for models J through RT. The DC brake is not
adjustable. As the friction material wears, the brake gap increases.
If the maximum air gap is reached, a new friction disc/rotor should
be installed.
