General Repair Information
CAUTION
To reduce the risk of a pressure control malfunc-
tion:
Always use needle nose pliers to disconnect a
wire. Never pull on the wire, pull on the connec-
tor.
Mate wire connectors properly. Be sure the flat
blade of the insulated male connector is centered
in the wrap-around blade of the female connec-
tor.
Route wires carefully to avoid interference with
the other connections of the pressure control. Be
sure the wires are not pinched between the cover
and the control box.

WARNING
ELECTRIC SHOCK HAZARD
To reduce the risk of serious injury,
including electric shock, DO NOT touch
any moving parts or electrical parts with
your fingers or a tool while inspecting the repair.
Shut off the sprayer and unplug it as soon as you
complete the inspection. Reinstall all covers,
gaskets, screws and washers before operating the
sprayer.
3. If the sprayer does not operate properly, review
the repair procedure again to verify that everything
was done correctly. If necessary, see the
Troubleshooting Guide, pages 12 – 16, to help
identify other possible problems and solutions.
CAUTION
Do not run the sprayer dry for more than 30 seconds
to avoid damaging the pump packings.
4. Reinstall the motor shield before regular op-
eration of the sprayer and replace it if it is dam-
aged. The cover directs cooling air around the
motor to help prevent overheating. It can also help
reduce the risk of burns, fire or explosion; see the
WARNING, below.
WARNING
EXPLOSION HAZARD
During operation, the motor and drive
housing become very hot and could burn
your skin if touched. Flammable materi-
als spilled on the hot, bare motor could cause a fire
or explosion. Always have the motor shield in place
during regular operation to reduce the risk of burns,
fire or explosion.
