the Reverse Valve Mechanism
Disassembly of the Reverse Valve Mechanism
The Reverse Valve Assembly cannot be removed
without first removing the Forward and
Reverse Buttons (4A) and (4B). Therefore, it is
important that the procedure below be followed
exactly.
1.
Notice the notches on either side of the partition.
These notches indicate the correct location for
insertion of a thin–bladed screwdriver used for
removing the Forward and Reverse Buttons. Insert the
screwdriver between the partition and the Button
which is fully extended. Gently pry against the
Button to disengage the detent so that the Button can
be removed. After the Button is removed, reach inside
the Housing and rotate the Reverse Valve to extend
the remaining Button. Repeat
the above procedure
for the remaining Button. Refer to Dwg. TPD1328.

bottom of the handle lightly with a rubber hammer
until it drops out.

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.
