checking or servicing the equipment.
D Tighten all fluid connections before operating the equipment.
D Check the hoses, tubes, and couplings daily. Replace worn, damaged, or loose parts immediately.
FIRE AND EXPLOSION HAZARD
Improper grounding, poor ventilation, open flames or sparks can cause a hazardous condition and result in a fire or explosion and serious injury.
D Ground the equipment and the object being sprayed. Refer to Grounding on page 4.
D If there is any static sparking or you feel an electric shock while using this equipment, stop spray-
ing immediately. Do not use the equipment until you identify and correct the problem.
D Provide fresh air ventilation to avoid the buildup of flammable fumes from solvents or the fluid
being sprayed.

Grounding
WARNING
FIRE AND EXPLOSION HAZARD
Before operating the pump, ground the
system as explained below. Also read
the section FIRE AND EXPLOSION
HAZARD on page 3.
Although water generally provides a natural electrical
ground, the following equipment must be grounded if
the cleaning chemicals are volatile.
1. When cleaning in enclosed areas, such as storage
tanks, locate the pump and air compressor outside
the area and well away from it. Provide adequate
ventilation. If the area you are cleaning has stored
flammable materials. take appropriate precautions
to avoid static sparking. Consult your local codes.
2. Pump: use a ground wire and clamp. See Fig. 1.
Remove the ground screw (Z) and insert through
the eye of the ring terminal at end of ground wire
(Y). Fasten the ground screw back onto the pump
and tighten securely. Connect the other end of the
wire to a true earth ground. Order Part No. 222011
Ground Wire and Clamp.
3. Air and fluid hoses: use only electrically conductive
hoses.
4. Air compressor: follow manufacturer’s recommendations.
5. Spray gun: ground through connection to a properly grounded fluid hose and pump.
6. Fluid supply container: follow your local code.
7. Object being sprayed: follow your local code.
8. Solvent pails used when flushing: follow your local
code. Use only metal pails, which are conductive,
placed on a grounded surface. Do not place the
pail on a nonconductive surface, such as paper or
cardboard, which interrupts the grounding continuity.
Fig. 1
9. To maintain grounding continuity when flushing or
relieving pressure, hold a metal part of the spray
gun firmly to the side of a grounded metal pail,
then trigger the gun.
