D 50 ft (15.2 m) 16 AWG
D 100 ft (30.5 m) 14 AWG
D 150 ft. (45.7 m) 12 AWG

Smaller gauge or longer extension cords may reduce sprayer
performance.

4 309388

D Ground sprayer gun through connection to a

properly grounded fluid hose and pump.

D Ground fluid supply container. Follow local code.

Grounding and Electric Requirements

D Ground 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 non–conductive surface such
as paper or cardboard, which interrupts the grounding continuity.

D Ground the metal pail by connecting a ground wire to the

pail by clamping one end to pail and the other end to
ground such as as water pipe.

ti5850a

D Maintain grounding continuity when flushing or

relieving pressure by holding metal part of spray gun
firmly to side of a grounded metal pail, then trigger gun.

Thermal Overload

To reduce risk of injury from motor staring

unexpectedly when it cools, always turn power
switch OFF if motor shuts down.

ti5851a

D Motor has a thermal overload switch

to shut itself down if overheated.

Graco equipment with structures, accessories, equipment or materials not supplied by Graco, or the improper design, manufacture,

NOT LIMITED TO WARRANTY OF MERCHANTABILITY OR WARRANTY OF FITNESS FOR A PARTICULAR PURPOSE.
