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) 14 AWG (2.1 mm
• 100 ft (30.0 m) 12 AWG (3.3 mm
Spray gun: ground through connection to a properly
grounded fluid hose and pump.
NOTE: Smaller gauge or longer extension cords may
reduce sprayer performance.

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 conti-
nuity when flushing or reliev-
ing pressure: 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 approximately 45
minutes for unit to cool. Once cool, switch will close and
unit will restart.

To reduce risk of injury from motor starting unex-
pectedly when it cools, always turn power switch
OFF if motor shuts down.
