Operation

Pressure Relief Procedure

WARNING

INJECTION HAZARD
Fluid under high pressure can be in-
jected through the skin and cause seri-
ous injury. To reduce the risk of an injury

from injection, splashing fluid, or moving parts, fol-
low the 

Pressure Relief Procedure whenever you:

are instructed to relieve the pressure,

stop spraying,

check or service any of the system equipment,

or install or clean the spray tips.

1. Engage the spray gun safety latch.

2. Close the pump air regulator.

3. Close the bleed-type master air valve (required in

your system).

4. Disengage the gun safety latch.

5. Hold a metal part of the gun firmly to a grounded

metal waste container and trigger to relieve the
fluid pressure.

6. Engage the safety latch again.

7. Open the pump drain valve (supplied with your

system), having a container ready to catch the
drainage.

8. Leave the drain valve open until you are ready to

spray again.

If you suspect that the spray tip or hose is completely
clogged, or that pressure has not been fully relieved
after following the steps above, 

very slowly loosen the

tip guard retaining nut or hose end coupling and relieve
pressure gradually, then loosen completely. Now clear
the tip or hose.

Flush the Pump Before Using

Pumps are tested with lightweight oil which is left in to
protect pump parts. To prevent fluid contamination,
flush the pump with a compatible solvent before using
it.

Starting and Adjusting the Pump

Note: Do not install the spray tip yet.

Connect the air line coupler (4) to the pin fitting (H).
Open the bleed-type master air valve (B).

Trigger the gun into a grounded metal container.
Holding a metal part of the gun firmly to the container,
slowly open the air regulator until the pump starts
running. Always use the lowest pressure necessary to
get the desired results.

WARNING

To reduce the risk of serious injury, including fluid
injection and splashing in the eyes or on the skin,
and property damage, never exceed the maximum
working pressure of the lowest rated component in
your system.

After all the air is purged, release the gun trigger. The
pump will start and stop as the gun is opened and
closed.

Follow the 

Pressure Relief Procedure at left and then

install the spray tip in the gun.

Never allow the pump to run dry of fluid being pumped.
A dry pump will quickly accelerate to a high speed,
possibly damaging itself (a pump runaway valve auto-
matically alerts you to this problem – see page 7). If
your pump accelerates quickly, or is running too fast,
stop it immediately  and check the fluid supply. If the
supply container is empty and air has been pumped
into the lines, prime the pump and lines with fluid, or
flush and leave filled with compatible solvent. Be sure
to eliminate all air from the fluid system.
