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.
• 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 9.
• Install motor shroud before operation of sprayer and
replace if damaged. Motor shroud directs cooling air
around motor to prevent overheating. It can reduce
risk of burns, fire or explosion, or cut fingers.
To reduce risk of serious injury, including electric shock:
• Do not touch moving or electric parts with fingers or
tools while testing repair.
• Unplug sprayer when power is not required for test-
ing.
• Install all covers, gaskets, screws and washers
before you operate sprayer.
CAUTION
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 control box.
CAUTION
• Do not run sprayer dry for more than 30 seconds.
Doing so could damage pump packings.
• Protect the internal drive parts of this sprayer from
water. Openings in the cover allow for air cooling of
the mechanical parts and electronics inside. If
water gets in these openings, the sprayer could
malfunction or be permanently damaged.
• Prevent pump corrosion and damage from freezing.
Never leave water or water-base paint in sprayer
when its not in use in cold weather. Freezing fluids
can seriously damage sprayer. Store sprayer with
Pump Armor to protect sprayer during storage.
