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 chart below 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 hoist and/ or
its associated components.
Interval
Lubrication Checks
Start of each
shift
Check flow and level of air line lubricator
(approximately 3 to 9 drops per minute
required at maximum motor speed).
Check oil levels in hoist and trolley piston
motors.
Monthly
Inspect and clean or replace air line filter.
Lubricate all grease fittings.
Check oil level in brake and reduction gear
assembly.
Quarterly
Drain and replace oil in trolley and hoist
piston drive motors.
Yearly
Drain and refill oil in hoist trolley and
reduction gear assembly.
Pivot Points and Bushings
Lubricate grease fittings monthly with 2 or 3 pumps
from a grease gun or more frequently, depending on
severity of service.

Hoist Motor
The motor is splash lubricated by oil in motor housing
and has no other means of lubrication. It is therefore
important to use only high quality, rust- and oxidation-
non-detergent inhibiting lubricant to ensure maximum
performance and minimum downtime for repairs.
Refer to
for recommended oil type. Allow
oil to settle prior to topping off. Oil capacity for HA2
hoist motor is 0.2 gals (0.76 ltr). Do not use synthetics
or detergents.

Piston Trolley Drive Motor
The motor is splash lubricated by oil in motor housing
and has no other means of lubrication. It is therefore
important to use only high quality, rust and oxidation-
inhibiting lubricant to insure maximum performance
and minimum down time for repairs. Allow oil to settle
prior to topping off. Oil capacity for HA2 trolley drive
motor is 0.1 pints (65 ml). Refer to
for
recommended oil.

Bottom Hook Block Assembly
Refer to Dwgs. MHP0314, MHP0315, MHP0316 and
MHP0317 in the Product Parts Information Manual.
To prevent moisture entering bottom block assemblies
they should periodically be repacked with grease.
Apply grease to grease fitting until grease escapes
through breather (421). Refer to
for
recommended grease types at specific temperature
ranges.

• 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 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 build-up and lubricate
chain.
