Chain Lubrication - CM Tornado 360 Manuel D'entretien, D'opération Et De Pièces

MAINTENANCE (CONTINUED)
Vernier Caliper
Measure 11 Pitches
Figure 7 - Chain Inspection
Also check chain for stretch using a vernier caliper as shown in
Figure 7. Select an unused, unstretched section of chain (usually
at the loose end) and measure and record the length over 11 chain
links (pitches). Measure and record the same length on a worn
section of chain.
If the result (amount of stretch and wear) is greater than 0.145 inch
(3.7 mm), the chain must be replaced.
Use only a "Knife-Edge" caliper to eliminate possibility of false
reading by not measuring full pitch length.
Using other than CM TORNADO 360° supplied load chain may
®
cause the chain to jam in the hoist and/or allow the chain to break
and the load to drop.
TO AVOID INJURY:
Due to size requirements and physical properties, use only CM
TORNADO 360° supplied load chain in the CM
lever hoist.
Note that worn chain can be an indication of worn hoist
components. For this reason, the hoist's frame, stripper, and
liftwheel should be examined for wear and replaced as necessary
when replacing worn chain (See DISASSEMBLY and ASSEMBLY).
Also, the load chain is specially heat treated and hardened and
should never be repaired.
IMPORTANT: Do not use replaced chain for other purposes such
as lifting or pulling. Load chain may break suddenly without visual
deformation. For this reason, cut replaced chain into short lengths to
prevent use after disposal.

CHAIN LUBRICATION

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
®
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.
Used motor oils contain known carcinogenic materials.
TO AVOID INJURY:
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.
When lubricating the chain, apply sufficient lubricant to obtain
natural run-off and full coverage, especially in the interlink area.
Hoist normally requires no additional lubrication except when it has
been disassembled for cleaning or repairs.
IMPORTANT: Brake is designed to operate dry. Do not use any
grease or lubricant on the braking 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 lubricating parts adjacent to the brake, do not use an
excessive amount of lubricant which could seep onto the brake
surfaces.
When the hoist is disassembled for cleaning or repairs, the following
locations should be lubricated with approximately 1 fl. oz. per hoist
of Molykote BR-2-S (Dow Corning), Molytex #2 (Texaco) or TopMoly
(Topsall) grease or equal lubricant: gears, liftwheel bushings, exterior
of pinion shaft, surfaces of frame bushings and surface of gear cover
bushings. Be sure to thoroughly clean the old grease from these
parts before re-lubricating.
IMPORTANT: To insure long life and top performance, be sure to
lubricate the various parts of the hoist using the lubricants specified
above. If desired, these lubricants can be purchased from Columbus
McKinnon (See Figure 13, page 11).
