A. Handle Kit
Remove heat shield (see procedure H, page 16). With
the nozzle of the applicator pointing away from you,
remove the seven Phillips head cap screws in the
handle. These screws are located in the left hand side
of the handle grip, two in the pistol grip itself, two just
forward of the wire terminal and three to the rear of the
wire terminal. Without removing the wires from the
wire terminals, lift the handle up and to the front of the
applicator. This operation will allow for subsequent
repair steps.
To replace applicator handles, first follow “Handle
Disassembly Instructions.” Next remove the electrical
wiring from the terminal strip on the left handle,
replacing them to the same terminals on the
replacement. The right half of the handle is removed by
removing the four Phillips head cap screws. Next
remove the electrical wiring from the terminal strip and
re-assemble these to the replacement right half handle.
Lift the switch out of its slot in the handle and replace
it in the new handle. Replace the trigger and trigger pin
at this time. Using reverse procedure, reassemble the
right handle half, then the left. Be sure all the electrical
wires are in place and are not being pinched.
