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 Basic
Troubleshooting, page 11 and Advanced Trouble-
shooting, page 16.
• 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 cover in
place. Replace if damaged. Covers direct cooling air
around motor to prevent overheating.
Flammable materials spilled on hot, bare, motor

fire or explosion, do not operate sprayer with cover
removed.

shock:
• Do not touch moving or electric pars with fingers or
tools while testing repair.
• Unplug sprayer when power is not required for test-
ing.

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.
