Grounding and Electric
Requirements
The sprayer cord includes a grounding wire with an
appropriate grounding contact.
The sprayer requires:
100-130 Vac, 60 Hz, 11A, 1 phase, circuit with a
grounding receptacle.
Never use an outlet that is not grounded or an
adapter.
Do not use the sprayer if the electrical cord has a dam-
aged ground contact. Only use an extension cord with
an undamaged ground contact.
Recommended extension cords:
110-120V: 3-wire, 12 AWG (2.5 mm2) minimum, 300 ft
(90 m) maximum length.
NOTE: Smaller gauge or longer extension cords may
reduce sprayer performance.
Spray gun: ground through connection to a properly
grounded fluid hose and pump.
Fluid supply container: follow local code.
Solvent and Oil-based fluids: follow local code. Use
only conductive metal pails placed on a grounded sur-
face such as concrete. Do not place the pail on a non-
conductive surface such as paper or cardboard, which
interrupts grounding continuity.
Grounding the metal pail: connect a ground wire to the
pail by clamping one end to pail and other end to ground
such as a water pipe.
To maintain grounding continuity when flushing or
relieving pressure: hold metal part of the spray gun
firmly to the side of a grounded metal pail, then trigger
the gun.

Pressure Relief Procedure
6311990J
Pressure Relief Procedure
Follow the Pressure Relief Procedure whenever
you see this symbol.
1. Turn OFF power and turn pressure control to lowest
pressure setting.
2. Hold gun against side of grounded metal flushing
pail. Trigger gun to relieve pressure.
3. Turn prime valve down.
If you suspect the spray tip or hose is clogged or that
pressure has not been fully relieved after following the
steps above, VERY SLOWLY loosen tip guard retaining
nut or hose end coupling to relieve pressure gradually,
then loosen completely. Clear hose or tip obstruction.
4. Engage trigger safety lock on gun if unit is being
shut down or left unattended.
This equipment stays pressurized until pressure is
manually relieved. To help prevent serious injury
from pressurized fluid, such as skin injection,
splashing fluid and moving parts, follow the Pressure
Relief Procedure when you stop spraying and before
cleaning, checking, or servicing the equipment.

General Repair Information
311990J 7
General Repair Information
• 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 Trou-
bleshooting, page 8.
• 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
insulates the control board from accidental electric
shock.
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
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 freez-
ing. Never leave water or water-base paint in
sprayer when its not in use in cold weather. Freez-
ing fluids can seriously damage sprayer. Store
sprayer with Pump Armor to protect sprayer during
storage.
