PRESSURE RELIEF PROCEDURE
5. Re-engage gun safety latch and close Prime/Pressure
Relief Valve.
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.
RELIEVING PRESSURE WILL BE DIFFERENT FOR EVERY BRAND OF AIRLESS PAINT SPRAYER, REFER
TO THE MANUAL THAT CAME WITH YOUR MACHINE TO RELIEVE PRESSURE. FOR AIRLESSCO BRANDED
MACHINES, USE THE PROCEDURE BELOW.
IMPORTANT!
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 uid pressure.
HOLD METAL PART OF THE GUN IN CONTACT WITH
GROUNDED METAL PAIL. USE MINIMUM PRESSURE !
100-180: 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.
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.
