ASSEMBLY
General Instructions
1. Whenever grasping a tool or part in a vise, always use
leather- - covered vise jaws to protect the surface of the
part and help prevent distortion. This is particularly
true of threaded members and housings.
Always use leather- - covered vise jaws when
clamping the handle in a vise. Leather will
conform to the shape of the handle and allow the
tool to be held securely. To prevent damage to the
exhaust diffuser, never clamp only the bottom of
the handle.
2. Always clean every part and wipe every part with a
thin film of oil before installation.
Do not remove grease from the impact mechanism
or Hammer Case (15). If the impact mechanism
has not been disassembled, inject Ingersoll- - Rand
No. 115- - 1LB Grease through the Hammer Case
Grease Fitting (17).
When disassembling and assembling the impact
mechanism, remove all grease from the impact
mechanism and Hammer Case and lubricate the
impact mechanism and Hammer Case Bushing (16)
with Ingersoll- - Rand No. 105- - 1LB Grease or
Ingersoll- - Rand No. 105- - 8LB Grease.
3. Apply a film of o- - ring lubricant to all O- - rings before
final assembly.
Assembly of the Reverse Valve Mechanism
1. Install the Bottom Reverse Valve O- - ring (3B)
(color- - coded blue) and the Top Reverse Valve bring
(3A) on the Reverse Valve (30).
2. Insert the Reverse Valve in the bottom of the handle
making sure that two ears on the Reverse Valve are
facing downward. Refer to Figure 8.

Valve is flush with or slightly above the bottom of
the motor bore in the Housing (19).
Refer to Figure 9.
Figure 9
If the Reverse Valve is pushed up too far and
becomes wedged, it will have to be pushed back
down through the the handle and re- - inserted from
the bottom of the handle. The Reverse Valve
cannot be removed by pushing it up through the
handle and into the motor bore. If the Reverse
Valve must be removed and re- - installed, make sure
that the Top and Bottom Reverse Valve O- - rings
have not been rolled off and are in their proper
positions on the Reverse Valve.
3. When the Reverse Valve has been installed, rotate the
Reverse Valve so that the tab on the Reverse Valve is
at the rear of the Housing. Refer to Figure 10.

If the orientation of the Reverse Valve is not
correct (tab facing the the rear of the Housing), the
Trigger (28) and the Forward and Reverse Buttons
(4A) and (4B) cannot be installed.
4. Install the Trigger O- - ring (2A) on the Trigger. Insert
the Trigger Assembly in the front of the Housing.
5. Rotate the Reverse Valve in either direction until an
ear comes up against the Trigger.
