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.
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 fluid pressure.
HOLD METAL PART OF THE GUN IN CONTACT WITH
GROUNDED METAL PAIL. USE MINIMUM PRESSURE !
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.
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.
1. Keep the displacement pump packing nut/wet cup lubricated with Airlessco TSO (Throat Seal Oil) at all times. The
TSO helps protect the rod and the packings.
2. Inspect the packing nut daily. Your pump has a patented Triple Life Packing System. Packing life will be extended a
minimum of three times if the following "Packing Adjustment" procedure is followed:
IF SEEPAGE OF PAINT INTO THE PACKING NUT AND/OR MOVEMENT OF THE PISTON UPWARD IS FOUND
(WHILE NOT SPRAYING), THE PACKING NUT SHOULD BE TIGHTENED ENOUGH TO STOP LEAKAGE ONLY,
BUT NOT ANY TIGHTER. OVERTIGHTENING WILL DAMAGE THE PACKINGS AND REDUCE THE PACKING LIFE.
DAILY MAINTENANCE
