5.
LOAD CHAIN. Measure the chain for stretching
by measuring across five link sections all along the
chain (ref. Dwg. MHP0041). When any five links
in the working length reach or exceed the discard
length shown in Table 2, replace the entire chain.
Always use a genuine Ingersoll-Rand replacement
chain.

Hoists not in Regular Service
1.
Hoists which have been idle for a period of one month or more, but less than one year should be given an inspection
conforming with the requirements of "Frequent Inspection" before being placed in service.
2.
Hoists which have been idle for a period of more than one year should be given a complete inspection conforming
with the requirements of "Periodic Inspection" before being placed in service.
3.
Standby hoists should be inspected at least semi-annually in accordance with the requirements of "Frequent
Inspection". In abnormal operating conditions equipment should be inspected at shorter intervals.
General
The use of thread lubricant or anti-seize compound is recommended for threaded components. Unless otherwise stated,
remove old lubricant, clean the part with an acid free solvent and apply a new coating of lubricant to the part before
assembly.
Gears
Unscrew nuts on the opposite side of the hoist as the hand chain, and remove gear cover and support plate. Remove old
grease and replace with new. For temperatures -29° to 10° C (-20° to 50° F) use EP 1 grease or equivalent. For
temperatures -1° to 49° C (30° to 120° F) use EP 2 grease or equivalent.
Load Chain
•
Failure to maintain clean and well lubricated load chain may result in chain failure causing injury, death or
substantial property damage.
1.
Lubricate each link of the load chain weekly. Apply new lubricant over existing layer.
2.
In severe applications or corrosive environment, lubricate more frequently than normal.
3.
Lubricate hook and hook latch pivot points with the same lubricant used on the load chain.
4.
To remove rust or abrasive dust build-up, clean chain with acid free solvent. After cleaning, lubricate the chain.
5.
Use Ingersoll-Rand LUBRI-LINK-GREEN or a SAE 50 to 90 EP oil.

BRAKES. Raise a load equal to the rated capacity
of the hoist a few centimeters (inches) off the floor.
Verify hoist holds the load without drift. If drift
occurs, contact your nearest service repair center
for repair information.

SUPPORTING STRUCTURE. If a permanent
structure is used inspect for continued ability to
support load.
8.
LABELS AND TAGS. Check for presence and
legibility. Replace if necessary.
