General Repair Information
• 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.
• Overspray may build up in the air passages.
Remove any overspray and residue from air pas-
sages and openings in the enclosures whenever
you service sprayer.
• Do not operate the sprayer without the motor shroud
in place. Replace if damaged. Motor shroud directs
cooling air around motor to prevent overheating and
insulate the control board from accidental electric
shock.
WARNING
Read Electric Shock Warning, page 3 and Burn
Hazard Warning, page 4.
WARNING
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.
WARNING
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
testing.
• Install all covers, gaskets, screws and washers
before you operate sprayer.
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.
