Inlet Bushing Screen by using a suitable cleaning

Disassembly of the Reverse Valve Mechanism
The Reverse Valve Assembly cannot be removed
without first removing the Forward and
Reverse Buttons (30) and (31). 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.
