•

Keep all screws, nuts, washers, gaskets, and elec-
trical fittings removed during repair procedures. 
These parts usually are not provided with replace-
ment kits.

•

Test repairs after problems are corrected.

•

If sprayer does not operate properly, review repair 
procedure to verify you did it correctly. See

Troubleshooting, page 13 and Advanced Trou-
bleshooting, page 18.

•

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 could 
cause fire or explosion. To reduce risk of burns, fire or 
explosion, do not operate sprayer with cover 
removed.

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.

• 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 malfunc-
tion 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.
