SAFETY PRECAUTIONS IMPORTANT READ and UNDERSTRND
United States Government safety standards have been adopted under the Occupational Safety and Health Act.
These standards
- particularly the General Standards, Part 1910, and the Construction Standards, Part 1926 -
should be consulted in connection with your use of airless spray painting equipment.
HIGH PRESSURE SPRAY CAN CAUSE SERIOUS INJURY. Because of the high pressure and velocity of the
spray, paint, solvent and fluids could penetrate the skin causing serious injury. Operate equipment only after
all
instructions are clearly understood.
KEEP AWAY FROM SPRAY
NEVERpoint the gun at yourself oranyone else. The tip
guard can provide additional protection against in-
jection injuries. Never put your hand, fingers or body
directly over the spray tip.
Always have the tip guard in place while spraying.
Even after you shut off the pump, there is high pressure

pressure. Leave drain valve
in open position during all
service operations. Have
a container ready to catch the
draining paint.
If the spray appears to have penetrated the skin,
SEEK
IMMEDIATE MEDICAL AlTENTION. DO NOT
TREAT AS A SIMPLE CUT.
Be ready to tell the doctor
exactly what fluid was injected.
Don't exceed
5000 PSI (350 bar1 working pressure to
gun. Be sure that all accessory items and system com-
ponents will withstand the pressures developed. NEVER
exceed the pressure rating of any component in system.
NEVER alter or modify equipment.
2 307-046
When spray gun is not actually spraying, always set gun
safety latch in closed, or "SAFE" position, making the
trigger inoperative.
Always remove tip from gun to clean
it.
Be very careful when removing spray tip or hose from
gun. A plugged line contains fluid under pressure. If the
tip or line is plugged, open drain valve, then loosen
tip
guard or hose coupling slightly and release pressure
slowly before removing completely.

Don't exceed maximum recommended air or hydraulic
PREVENT STATIC SPARKING
The high velocity flow of material through the spray tip
may develop static electricity. Be sure your gun is
grounded. Use grounded paint hoses and be sure your
supply pump and the object you are painting are
grounded.
Always use the lowest pressure possible when flushing
and hold gun firmly against metal waste container.
