LUBRICATION
Each time a Series 2925P1Ti and 2925P3Ti Impactool is
disassembled for maintenance and repair or replacement of
parts, lubricate the tool as follows:
1.
Work approximately 12 to 15 cc of Ingersoll–Rand No.
170 Grease into the impact mechanism. Coat the Anvil
(40, 42 or 48) lightly with grease around the Hammer
Case Bushing (38). Inject approximately 2 to 4 cc of
grease into the Grease Fitting (17).
2.
Use Ingersoll–Rand No. 50 Oil for lubricating the
motor. Inject approximately 1 to 2 cc of oil into the air
inlet before attaching the air hose.
DISASSEMBLY
General Instructions
1.
Do not disassemble the tool any further than necessary

subassembly unless the removal of that part is neces-
sary for repair or replacement.
4.
Do not disassemble the Impactool unless you have a
complete set of new gaskets and o–rings for replace-
ment.
