vice, as shown in the diagram above.
An in-line shutoff ball valve is an
important safety device because it
controls the air supply even if the
air hose is ruptured. The shutoff
valve should be a ball valve be-
cause it can be closed quickly.
Note: An oiler system should not be used
with this spray gun. The oil will mix
with the material being propelled,
causing poor results.
2. Attach an air hose to the compres-
sor's air outlet. Connect the air
hose to the Air Inlet of the spray gun.
Other components, such as a coupler
plug and quick coupler, will make
operation more efficient, but are not
required.
WARNING! TO PREVENT SERIOUS
INJURY FROM ACCIDENTAL
OPERATION:
Do not install a FEMALE quick
coupler on the spray gun. Such a
coupler contains an air valve that will
allow the spray gun to retain pressure
and operate accidentally after the air
supply is disconnected.
Note: Air flow, and therefore spray gun
performance, can be hindered by
undersized air supply components.
3. The air hose must be long enough
to reach the work area with enough
extra length to allow free movement
while working.
4. Release the spray gun's Trigger.
5. Close the in-line safety Valve be-
tween the compressor and the spray
gun.
6. Turn on the air compressor according
to the manufacturer's directions and

allow it to build up pressure until it
cycles off.
7. Adjust the air compressor's output
regulator so that the air output is
enough to properly power the spray
gun, but the output will not exceed
the spray gun's Operating Air Pres-
sure at any time. Adjust the pres-
sure gradually, while checking the air
output gauge to set the right pressure
range.
8. Inspect the air connections for leaks.
Repair any leaks found.
9. If the spray gun will not be used at
this time, turn off and detach the air
supply, safely discharge any residual
air pressure, and release the trigger
to prevent accidental operation.
Note: Residual air pressure should not be
present after the spray gun is discon-
nected from the air supply. However,
it is a good safety measure to attempt
to discharge the spray gun in a safe
fashion after disconnecting to ensure
that the spray gun is disconnected
and unpowered.
