LUBRICATION
To ensure continued satisfactory operation of hoist, all points requiring lubrication
must be serviced with correct lubricant at proper time interval as indicated for each
assembly.
Refer to ‘Maintenance Interval’ chart in Product Maintenance Information Manual for
recommended lubrication intervals. Use only those lubricants recommended. Other
lubricants may affect product performance. Approval for use of other lubricants must
be obtained from your
Ingersoll Rand
distributor. Failure to observe this precaution
may result in damage to winch and/or its associated components.
INTERVAL
LUBRICATION CHECKS
Weekly
Lubricate load chain.
Monthly
Inspect and clean or replace oil filter.
Lubricate components supplied by grease fittings.
Quarterly
Check reduction gear oil level.
Yearly
Change reduction gear oil.

General Lubrication
WARNING
• Pneumatic Hoists use oil to prevent excessive heat build up and to prevent
wear that could cause sparks. Oil levels must be properly maintained.
Always collect lubricants in suitable containers and dispose of in an environmentally
safe manner.

Reduction Gear Assembly
Refer to Dwg. MHP3135 on page 9,

Fill Plug;
B.
Drain Plug;
C.
Oil Level Plug;
D.
Motor Side.
Replace the oil in the reduction housing once every year. If the hoist is used at a
normal frequency, the oil in the reduction housing is suitable for one year's operation
without being changed. However, when the hoist is used at a high frequency, the oil
may need to be changed more often.
To ensure correct performance, highest efficiency and long life, it is essential that
the lubricating oil be maintained at the correct level. The recommended grade of oil
must be used at all times since the use of unsuitable oil may result in excessive
temperature rise, loss of efficiency and possible damage to the gears.
NOTICE
• Only use synthetic oil.

To replace oil remove fill plug and add oil to the reduction gear assembly, replace
plug. Refer to Product Parts Information Manual.

Seals and Bearings
If hoist is disassembled, clean all parts thoroughly and coat bearings and seals with
clean grease. Use sufficient grease to provide a good protective coat.
n
Hook Assemblies
Hoist top and bottom hooks are supported by thrust bearings. These bearings must
be packed with
Ingersoll Rand
No. 68 Grease or a standard No. 2 multi-purpose grease
at regular intervals. Neglect of proper lubrication can lead to bearing failure.
1. Lubricate hook and latch pivot points. Refer to Dwg. MHP1300 on page 9,
A.
Hook latch pivot point. Hook and latch should swivel/pivot freely.
2. Use
Ingersoll Rand
LUBRI-LINK-GREEN® or ISO VG 220 (SAE 50W) lubricant.
3. Lubricate hook bearings by applying several shots of grease from a grease gun to
the grease fittings provided on the hook blocks.
n
Trolley (optional feature)
Grease wheel bearings and wheel drive gear with
Ingersoll Rand
No. 68 Grease or a
standard No. 2 multi-purpose grease periodically. Refer to manufacturer’s literature
for additional lubrication information.
n
Load Chain
WARNING
• Failure to maintain a 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 each link of load chain weekly, or more frequently, depending on
severity of service.
2. In corrosive environments, lubricate more frequently than normal.
3. Lubricate each link of the load chain and apply new lubricant over existing layer.
4. Lubricate hook and hook latch pivot points.
5. If required, clean chain with acid free solvent to remove rust or abrasive dust
buildup and lubricate chain.
6. Use
Ingersoll Rand
LUBRI-LINK-GREEN® or an ISO VG 220 to 320 (SAE 50W to 90
EP) oil.
