Spray GurdDispensing Valve Safety Devices
Be sure all gunldispensing valve safety devices are operating
properly before each use.
Do not remove or modify any part of
the gun or dispensing valve; this can cause a malfunction and
result in serious bodily injury.
Safety Latch
Whenever you stop spreyingldispensing, even for a moment,
always set the safety latch
in the closed or " safe " position,
making the gunldispensing valve inoperative. Failure to set
the safety latch cen result
in accidental triggering of the
gunldispensing valve.
Diffuser (only
on spray guns)
The gun diffuser breaks up spray and reduces the risk of fluid
injeciion when the tip is not installed. Check diffuser operation
regularly. Follow the Pressure Relief Procedure, at the
right, and then remove the spray tip. Aim the gun into a
grounded metal pail, holding the gun firmly to the
pail. Using
the lowest possible pressure, trigger the gun. If the fluid emit

General
Safety
Any misuse of the sprayldispensing equlpmenr or ac -
cessories, such as overpressurizing, modifying parts, using in -
compatible chemicals and fluids, or using worn or damaged
parts, can cause them to rupture and result in fluid injection or

Read and follow the fluid and solvent manufacturer's literature
regarding the use of protective clothing and equipment.
System Pressure
The maximum safe working pressure is determined by the air
motor.
DO NOT exceed the maximum working pressure stated
on your complete pump. Be sure
that all system components
and accessories are rated to withstand the maximum working
pressure of the complete pump.
Fluid Compatibility
BE SURE that all fluids and solvents used ere chemically corn:
oatible with the wetted Darts shown in the Technical Date on
the back cover. Always read the manufacturer's literature
bwfore using fluid or solvent in this pump.

IMMEDIATELY. Check the entire system for positive ground-
identified and corrected.
Grounding
To reduce the risk of static sparking, ground the pump and ail
other components used or located in the sprayldispensing
area. CHECK your local electrical code foi detailed grounding
instructions for your area and type of equipmenrand be sure
to ground all
of these components:
1.
Pump: Ground the complete pump as indicated in your
separate instruction manual.
2. Air and fluid hoses: use only grounded hoses with a max -
imum of 500 feet (150 m) combined hose length to en -
sure grounding continuity. Refer to Hose Grounding
, Continuity.
3. Air compressor: follow the air compressor manufacturer's
recommendations.
4. Spray gun/dispensing valve: obtain grounding through
connection to
a properly grounded fluid hose and pump.
5. Fluid Supply Container: according to local code,
6. Object being sprayed: according to local code.
7. All solvent pails used when flushing, according to local
code. Use onlymetalpails, which are conductive.
Do not
place the pail on a non
- conductive surface, such as paper
or cardboard, which interrupts the grounding continuity.
8. To maintain grounding continui?y when flushing orreliev-
ingpressure, always hold a metal part of the gun firmly to
the side of a grounded metal pail, then trigger the gun.
Flushing Safety
Before flushing, be sure the entire system and flushing pails
are properly grounded. Refer to Groundlng, above. Follow
the Pressure Rellef Procedure on page
2, and remove the
the lowest possible fluid pressure, and maintain firm metal-to-
spray tiplnozzle from the gun/dispensing valve. Always use
metal contact between the gunldispensing valve and the pail
during flushing to reduce the risk of fluid injection injury, static
sparking and splashing.
HOSE SAFETY
High pressure fluid in the hoses can be very dangerous. If the
hose develops
a leak, split or rupture due to any kind of wear,
damage
or misuse, the high pressure spray emitted from it can
cause a fluid injection injury or other serious bodily injury or
properly damage.
ALL FLUID HOSES MUST HAVE SPRING GUARDS ON
BOTH ENDS1 The spring guards help protect the hose from
kinks or bends at or close to the coupling which can result
in
hose rupture.
TIGHTEN all fluid connections securely before each use. High
pressure fluid can dislodge a loose coupling or allow high
pressure spray to
be.emitted from the coupflng.
NEVER use a damaged hose. Before each use, check the en -
tire hose for cuts, leaks, abrasion, bulging cover, or damage or
movement of the hose couplings.
If any of these conditions
exist. replace the hose immediately.
DO NOT try to recouple
high pressure hose or mend
it with tape or any other device. A
repaired hose cannot contain the high pressure fluid.
HANDLE AND ROUTE H O SES CAREFULLY . DO not pull on
hoses to move eouiDment. Do not use fluids or solvents which

MOVING PARTS HAZARD
The piston in the air motor, located behind the air motor

can pinch or amputate your fingers or other body parts.
