HIGH PRESSURE SPRAY CAN CAUSE SERIOUS INJURY.
FOR PROFESSIONAL USE ONLY. OBSERVE ALL WARNINGS.
Read and understand all instruction manuals before operating equipment.
FLUID INJECTION HAZARD
General Safety
This equipment generates very high fluid pressure. Spray from
the gun, leaks or ruptured components can inject fluid
through your skin and into your body and cause extremely
serious bodily injury, including'the need for amputation. Also,
fluid injected or splashed into the eyes or
on the skin can
cause serious damage.
NEVER point the spray gun
at anyone or at any pan of the
body. NEVER put hand
or fingers over the spray tip.

Spray
Gun Safety Devices
Be sure all gun safety devices are operating properly before
each
use. Do not remove or modify any pan of the gun; this
can cause a malfunction and result in serious bodily injury.
Sefew Latch
Whenever you stop spraying, even for a moment, always set
the gun safety latch in the closed or "safe" position, making
the gun inoperative. Failure to set the safetv latch can result in
accidental triggering of the gun.
Diffuser
The gun diffuser breaks up spray and reduces the risk of fluid
injection when the tip
is not instelled. Check diffuser operation
regularly. Follow the Preeeure
Relief Procedure, to the
right, then remove the spray tip. Aim the gun into a grounded
metal pail. holding the gun firmly to the pall. Using the 1-
possible pressure, trigger the gun. If the fluid emitted is not
diffused into an irregular stream, replace the diffuser im-
mediately.
Tip Guard
ALWAYS have the tip guard in place on the spray gun while
spraying. The tip guard alerts you to the fluid injection hazard
and helps reduce, but does not prevent, the risk of acciden-
tally placing your fingers or any pan of your body close to the
spray tip.
Trig
er Guard
NEVfR operate the gun with the trigger guard removed. The
trigger guard reduces the risk of accidentally triggering the
gun if it is dropped or bumped.

Pressure Relief Procedure
To reduce the risk of serious bodily injury, including fluid injec-

whenever you stop spraying.

your local electrical code for detailed grounding instructions
for your area and type of equipment and be sure to ground all
of these components:

code. Use only metalpails, which are conductive. Do not
place the pail on a non-conductive surface, such as paper
or cardboard, which interrupts the grounding continuity.
