are spraying indoors or outdoors, and can cause a fire or ex-
plosion and serious bodily injury and property damage. Do not

G r o u n d i n g
To reduce the risk of static sparking, ground the pump and all
other spray equipment used or
located in the spray area.
CHECK your local electrical code for detailed grounding in-
structions for your area and type of equipment. BE SURE to
ground all of this spray equipment:
1. Pump: use a ground wire and clamp as shown in Fig
1.
2. Air hoses: use only grounded air hoses.
3.
Fluid hoses: use only grounded fluid hoses.
4. Air compressor: follow manufacturer's recommendations.

gun
or
dispensing velve: grounding is obtained
through connection to a properly grounded fluid hose and
pump.
6.
Fluid supply container: according to local code.
7.
Object being sprayed: according to your lo&l code.

Flushing
Safety
To reduce
the risk of injection injury, static sparking, or
splashing follow the Pressure Relief Procedure on page
2 ,
and remove the spray
tip
(spray guns or spray valves only)
before flushing. Hold a metal part of the gunlvalve firmly
to
the side of a grounded metal pail and use the lowest possible
fluid pressure during flushing.
MOVING PARTS HAZARD
The piston in the air motor, located behind the
air motor
plates, moves when air

supplied to the motor. Moving pa-
can pinch or amputate your fingers
or other body parts.
Therefore, NEVER operate the pump with the air motor plates
removed. KEEP CLEAR
of moving parts when starting or
operating the pump. Before checking or servicing the pump,
follow the Pressure Relief Procedure on page
2
to prevent
the pump from starting accidentally.
HOSE SAFETY
High pressure fluid in the hoses can be very dangerous. If the
