After inspection and before being
returned to service, chains must be
lubricated with a quality chain
lubricant (ìLUBRIPLATEî Chain &
Cable Fluid, ìLPS3î or equivalent).
The lubricant must penetrate the chain joint to prevent wear. Applying lubricant to
the external surfaces will prevent rust, but the chains should be articulated to make
sure the lubricant penetrates to the working surfaces between the pins and links.
To prepare the chain for lubrication, the chain plates should be brushed with a stiff
brush or wire brush to clear the space between the plates so that lubricant can
penetrate to the working surfaces.
Lubricant may be applied with a narrow paint brush or directly poured on, but the
chain should be well flooded with lubricant and the boom should be extended and
retracted to be sure that the lubricant penetrates to the working surfaces. All surplus
lubricant should be wiped away from the external surfaces. DO NOT use a solvent
for this wiping operation.
Regular application of lubricant is necessary to make sure that all working surfaces
are adequately lubricated. In extremely dusty conditions, it may be necessary to
lubricate the chains more often.
Lubrication of chains on vehicles working consistently in extreme hot or cold
conditions requires special consideration. It is important that a reputable lubrication
specialist, a Lull Distributor or the vehicle distributor be consulted for guidance.
