Repair Procedures
A. Handle Kit
Disconnect electrical and compressed air service.
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
reassemble 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.
Handle Disassembly Instructions
Caution
Prior to making any repairs on the applicator, make
certain that the applicator is at room temperature and
that both air and electrical service lines have been
disconnected from their respective sources. Failure to
disconnect the electrical power source could result in
electrical shock. Heat shield must be in place before
connecting applicator to electrical outlet.

Heat Shield Disassembly
Instructions
Disconnect Electrical and Compressed Air Service.
Remove the heat shield assembly by removing the two
Phillips head screws from either side of the heat shield
and the one Phillips head screw on the heat shield
immediately above the loading chamber. Reassemble,
following reverse procedure.
Handle Disassembly Instructions
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. Remove the long screw on the
bottom left of the flange immediately above the three
screws located 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.
