WARNING
HOT SURFACES HAZARD
EXPLOSION HAZARD
Motor and drive housing may be very hot
during operation and could burn skin if
touched.
Flammable materials spilled on hot, bare
motor could cause fire or explosion.
Have enclosures in place during
operation to reduce risk of burns, fire, or
explosion.
D Keep all screws, nuts, washers, gaskets, and
electrical fittings that you remove during repair
procedures. These parts are not normally provided
with replacement assemblies.
D Test repairs after problems are corrected.
D If the sprayer does not operate properly, review
the repair procedure to verify that you did it cor-
rectly. See Troubleshooting on page 8 and
Advanced Troubleshooting on page 10.
D Overspray may build up in the air passages.
Remove any overspray and residue from the air
passages and openings in the enclosures whenever
you service the sprayer.
Do not operate the sprayer without the enclosure.
Replace if damaged. Enclosures direct cooling air
around the motor to prevent overheating. They also
reduce the risk of burns, fire or explosion. Read the
following WARNING.
WARNING
ELECTRIC SHOCK HAZARD
MOVING PARTS HAZARD
To reduce risk of serious injury, including
electric shock, do not touch moving or
electrical 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 enclosures allow for air
cooling of the mechanical parts and electronics
inside. If water gets into these openings, the sprayer
could malfunction or be permanently damaged.
Prevent pump corrosion and damage from freez-
ing. Never leave water or water-base paint in
the sprayer when it is not in use in cold weather.
Freezing fluids can seriously damage the sprayer.
Store the sprayer with mineral spirits/paint thinner or
Graco Pump Armor to protect equipment during
storage.
