Pressure Relief Procedure; Daily Maintenance - AIRLESSCO LP460 Service & 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 & unplug it from the electrical outlet.
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
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.
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.

DAILY MAINTENANCE

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.
