2. Pour enough clean, compatible solvent into a large,
empty metal pail to fill the pump and hoses.
3. Place the suction tube into the pail.
4. Turn the Prime/Pressure Relief (PR) Valve to the
"OPEN" , priming position. Refer to Figure 1.
5. Point the gun into the metal pail and hold a metal
part of the gun firmly against the pail. Refer to Figure 5.
To reduce the risk of static sparking
which can cause fire or explosion,
always hold a metal part of the gun firmly
against the metal pail when flushing. This
also reduces splashing.

6. Disengage the gun safety latch and squeeze the
gun trigger. Turn the ON-OFF Toggle Switch to the
"ON" position (Figure 3) and turn Pressure Control
Knob (Figure 2) clockwise to increase pressure just
enough to start the pump.
7. Turn the Prime/PR Valve to the PRESSURE
"CLOSED" position. This will allow solvent to be
flushed through the pump, hoses and gun. Allow the
unit to operate until clean solvent comes from the gun.
8. Release the trigger and engage the gun safety
latch.
9. Whenever you shut off the sprayer, follow the
"PRESSURE RELIEF PROCEDURE".
