Graco 257070 Manual De Usuario

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 spray-
ers require a 120 
Vac, 60 Hz, 15A cir-
cuit with a ground-
ing 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 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

2

)

•

100 ft (30.0 m) 12 AWG (3.3 mm

2

)

 

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 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.

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.

Smaller gauge or longer extension cords may 
reduce sprayer performance.

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