WARNING
To reduce the risk of static sparking and splashing
when flushing, always remove the spray tip from
the gun and hold a metal part of the gun firmly to
the side of a grounded metal pail.
WARNING
To reduce the risk of a serious injury, follow the
Pressure Relief Procedure on page 4 whenever
you are instructed to relieve the pressure.
1.
Relieve the pressure.
2.
Turn the pressure–adjusting knob (A) fully counter-
clockwise to the minimum pressure.
3.
Remove the spray tip from the gun. Remove the
filter bowl (B) and the screen (C), but leave the
support (D) in place. Install the bowl without the
screen. See Fig. 7.
4.
Put the suction tube into a grounded metal–pail
with 1/2 gallon (2 liters) of a compatible solvent.
5.
Start the sprayer. See page 12. To save the fluid
still in the sprayer, trigger the gun into another
container until the next fluid appears, then trigger
the gun back into the fluid you are pumping. Circu-
late the flushing fluid for a few of minutes to thor-
oughly clean the system.
6.
Do not run the pump dry for more than 30 seconds
to avoid damaging the pump packings!
7.
Relieve the pressure. Lock the gun trigger safety.
