DISASSEMBLY
General Instructions
1. Do not disassemble the tool any further than
necessary to replace or repair damaged parts.
2. 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.
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 Impact Wrench
1. Clamp the handle of the impact wrench in a vise with
leather- - covered jaws with the square driver
positioned horizontally.
Avoid excessive clamping pressure which can
damage the Housing and can cause difficulty when
removing the parts.
2. Unscrew and remove the four Hammer Case Screws
(11).
3. While lightly tapping on the end of the Anvil (8) with
a plastic hammer, lift off the Hammer Case (15) and
Hammer Case Gasket (18).
The Front End Plate (2) might come off during the
removal of the Hammer Case. Make sure that it
does not drop on the floor or strike a hard or
metallic surface since it might be damaged.
4. Grasp the Hammer Frame (12) and carefully lift off
the entire impact mechanism, making certain not to
drop the two Hammer Pins (13).
