Grounding and Electric
Requirements
Sprayer must be grounded. Grounding reduces
the risk of static and electric shock by providing an
escape wire for electrical current due to static build
up or in the event of a short circuit.
• The 120 Vac
sprayers require a
120 Vac, 60 Hz,
15A 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
damaged ground prong.
• Only use an extension cord
with an undamaged 3-prong
plug.
Recommended extension cords for use with
this sprayer:
• 50 ft (15.0 m) 16 AWG (1.0 mm2)
• 100 ft (30.0 m) 14 AWG (1.5 mm2)
Spray gun:ground through connection to a prop-
erly grounded fluid hose and pump.
Fluid supply container:follow local code.
Solvent pails used when flushing: follow local
code. Use only conductive metal pails, placed on a
grounded surface such as concrete. Do not place
the pail on a nonconductive 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.
Maintaining grounding
continuity when flush-
ing or relieving pres-
sure: hold metal part of
the spray gun firmly to the
side of a grounded metal
pail, then trigger the gun.
Thermal Overload
Motor has a thermal overload switch to shut itself
down if overheated. If unit overheats, allow approx-
imately 45 minutes for unit to cool. Once cool,
switch will close and unit will restart.
WLD
WLD
Smaller gauge or longer extension cords may
reduce sprayer performance.
To reduce the risk of injury from motor starting
unexpectedly when it cools, always turn power
switch OFF if motor shuts down.
