Maintenance
Always wear eye protection when operating
or performing maintenance on this tool.
Lubrication
Each time a Series 2705P1 Impactool is

replacement of parts, lubricate the tool as
follows:
1. Work approximately 4 to 6 cc of
Ingersoll-Rand No. 100 Grease into the
impact mechanism. Coat the Anvil (43)
Disassembly
General Instructions
1. Do not disassemble the tool any further
than necessary to replace or repair damaged
parts.
2. When grasping a tool or part in a vise,
always use leather-covered or copper-
covered vise jaws to protect the surface of
the part or tool and help prevent distortion.
This is particularly true of threaded members
and housings.
3. Do not remove any part which is a press fit
in or on a subassembly unless the removal of
that part is necessary for repairs or
replacement.
4. Do not disassemble the tool unless you have
a complete set of new gaskets and O-rings
for replacement.
Disassembly of the Impactool
1. 1. Clamp the handle of the Impactool in a
vise with the square driver upward.
2. 2. Unscrew and remove the three Hammer
Case Cap Screws (41).
3. 3. While lightly tapping on the end of the
Anvil (43) with a plastic hammer, lift off the
Hammer Case (38).
4. 4. Grasp the Hammer Frame (34) and
carefully lift off the entire impact
mechanism, making certain not to drop the
two Hammer Pins (35). If it is necessary to
disassemble the impact mechanism, refer to
Disassembly of the Impact Mechanism. If
it is unnecessary to disassemble the impact
mechanism, set it aside intact.
2
Always turn off the air supply and
disconnect the air supply hose before
installing, removing or adjusting any
accessory on this tool or before performing
any maintenance on this tool.
lightly with grease around the Hammer Case
Bushing (40). Inject approximately 1 to 2 cc
of grease into the Grease Fitting (2).
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 of the Impact
Mechanism
1. Set the mechanism, driver end up, on the
workbench.
Note the twin Hammers (37) within the
Hammer Frame. These are identical but must
be placed in the Hammer Frame in a certain
relationship. Using a felt-tipped pen, mark
the top hammer "T " and the bottom
hammer "B " with the arrows pointing
upward. Mark both Hammers on the same
end.
2. With the mechanism sitting upright on the
workbench, slowly rotate the Anvil in a
clockwise direction until it comes up solid.
If you continue to rotate the Anvil, it will
cam the Hammers out of engagement. Don't
do this; merely rotate the Anvil until it
comes up solid.
3. Hold the Hammer Frame firmly and, without
disturbing the hammers, gently lift the
Anvil, simultaneously rotating it clockwise
about 1/8 of a turn, from the Hammer
Frame.
