Grounding and Electrical Requirements
Spray gun: ground through connection to a properly
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.
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.

Thermal Overload

Motor has a thermal overload switch to shut itself down
if overheated.
WARNING
To reduce risk of injury from motor starting unex-
pectedly when it cools, always turn power switch
OFF if motor shuts down.
