Pressure Relief Procedure - AIRLESSCO Spray & Stripe 3600 Service And Operation Manual

Pressure Relief Procedure

IMPORTANT!
To avoid possible serious body injury, always follow this procedure whenever the
sprayer is shut off, when checking it, when installing, changing or cleaning tips,
whenever you stop spraying, or when you are instructed to relieve the pressure.
1. Engage the gun safety latch. Refer to the
separate instruction manual provided with
your gun on its safety features and how to
engage safety latch.
2. Turn the unit off.
3. Disengage the gun safety latch and trigger
the gun to relieve residual fluid pressure.
Hold metal part of the gun in
contact with grounded metal pail.
USE MINIMUM PRESSURE !
If the SPRAY TIP OR HOSE IS CLOGGED, follow Step 1 through 5 above. Expect paint
splashing into the bucket while relieving pressure during Step 4.
If you suspect that pressure hasn't been relieved due to damaged Prime/Pressure
Relief Valve or other reason, engage the gun safety latch and take your unit to an
authorized Airlessco Service Center.
4. Turn Prime/Pressure Relief Valve (PR Valve)
to the open (priming) position to relieve
residual fluid pressure.
There will be a wider gap between valve
handle and cam body when in open
position. In the closed position there is
only a very slight gap.
.
Note: The valve handle can move both
clockwise and counter clockwise and can
face different directions.
5. Re-engage gun safety latch and
close Prime/Pressure Relief Valve.
