Grounding
8 3A2333B
Grounding
The sprayer cord includes a grounding wire with an appro-
priate grounding contact.
This sprayer requires 220-240 VAC, 50/60 Hz 10A circuit (or
110 VAC, 50/60 Hz 15A for UK units) with a grounding recep-
tacle. Never use an outlet that is not grounded.
Do not modify plug! Tampering with the plug will result in a
voided warranty. Do not use sprayer if electrical cord has
damaged ground prong.
If plug will not fit in outlet, have grounded outlet installed by a
qualified electrician. Do not use an adapter.
NOTE: Smaller
gauge or longer extension cords may reduce sprayer perfor-
mance.
Pails
Do not place pail on a nonconductive surface such as
paper or cardboard which interrupts grounding continuity.
Grounding a metal pail: connect a ground wire to the pail by
clamping one end to pail and other end to a true earth ground.
To maintain grounding continuity when flushing or
relieving pressure:
hold metal part of spray gun firmly to side
of a grounded metal pail. Then trigger gun.
Thermal Overload
Motor has a thermal overload switch to shut itself down if over-
heated. If sprayer overheats, allow approximately 45 minutes
for sprayer to cool. Once cool, switch will close and sprayer
will restart.
The equipment must be grounded to reduce the risk of static
sparking and electric shock. Electric or static sparking can
cause fumes to ignite or explode. Improper grounding can
cause electric shock. Grounding provides an escape wire for
the electric current.
To reduce the risk of static sparking, explosion and elec-
tric shock when using solvent and oil/based fluids,
use
only conductive metal pails, placed on a grounded surface
such as concrete.

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