Warning: Always ensure the hoist is disassembled and powered off before starting the lubrication process.

CAUTION! Do not use automotive type detergent oil. Detergents will delaminate the motor vanes and cause premature failure.

Sign off on the lubrication process

WARNING! Failure to maintain clean and well lubricated load chain will result in rapid load chain wear that can lead to chain failure which can cause severe injury, death or substantial property damage.

1. Lubricate load chain weekly, or more frequently, depending on severity of service.

2. In a corrosive environment, lubricate more frequently than normal.

3. Lubricate each link of the load chain and apply new lubricant over existing layer.

4. If required, clean chain with acid free solvent to remove rust or abrasive dust buildup and lubricate the chain.

5. Use Ingersoll Rand LUBRI-LINK ® or a SAE 50 to 90 EP oil.

1. Lubricate the hook and hook latch pivot points. Hook and latch should swivel / pivot freely.

2. Use Ingersoll Rand LUBRI-LINK® or a SAE 50 to 90 EP oil.

Warning: This inspection should be conducted by trained personnel only.

Operation: Check for visual signs or abnormal noises (grinding etc.) which could indicate a potential problem. Make sure all controls function properly and return to neutral when released. Check chain feed through the hoist and bottom block.

Hooks: Check for wear or damage, increased throat width, bent shank or twisting of the hook. Check hooks swivel freely.

Hook Latch: Make sure the hook latch is present and operating.

Upper and Lower Limit Device: Test operation with no load slowly to both extremes of travel.

Limit Assembly: Check limit arm moves freely.

Air System: Visually inspect all connections, fittings, hoses and components for indication of air leaks.

Controls: During operation of hoist, verify response to pendant is quick and smooth. See that the controls return to neutral when released.

Load Chain: Examine each of the links for bending, cracks in weld areas or shoulders, traverse nicks and gouges, weld splatter, corrosion pits, striation (minute parallel lines) and chain wear.
