General Repair Information
Flammable materials spilled on hot, bare motor could
cause fire or explosion. To reduce risk of burns, fire or
explosion, do not operate sprayer with cover removed.
NOTICE
To reduce risk of pressure control malfunction:
• Use needle nose pliers to disconnect wire.
Never pull on wire, pull on connector.
• Mate wire connectors properly. Center flat
blade of insulated male connector in female
connector.
• Route wires carefully to avoid interference
with other connections or pressure control.
Do not pinch wires between cover and con-
trol box.
• Keep all screws, nuts, washers, gaskets, and electri-
cal fittings removed during repair procedures. These
parts usually are not provided with replacement kits.
• Test repairs after problems are corrected.
• If sprayer does not operate properly, review repair
procedure to verify you did it correctly. See Trouble-
shooting, page 11.
• Install motor shroud before operation of sprayer and
replace if damaged. Motor shroud directs cooling air

sprayer could malfunction or be permanently
damaged.

ing. Never leave water or water-base paint in
