Operation
Preparing Guns/Cups for the Gun Washer
1.
Remove the pressure cup or fluid line and the air
line from the spray gun.
2.
Drain any excess fluid in the gun or cup into a fluid
container. The solvent in the gun washer will last
longer if pressure cups are thoroughly emptied
before placing them in the gun washer.
CAUTION
All pressure gauges must be removed before placing
the equipment in the gun washer to avoid damaging
the gauges.
3.
To lock the gun trigger in the open position, install
the wire trigger lock around the gun handle and
trigger as shown in Fig. 3.
If the wire trigger lock does not fit on your electro-
static gun, wrap the chain around the trigger and
handle to hold the trigger in an open position.
