is no pressure in the unit, and close the prime/pressure relief valve for storage.

Never leave pump

! WARNING unattended while it is under pressure!

6. START UP AFTER STORAGE: Before using water-base paint, flush with soapy water and then a clean water flush. Before using oil-base paint, flush out the mineral spirits with the material to be sprayed.

HOW TO FLUSH

IMPORTANT COMPONENTS

●Prime/Pressure Relief Valve (Prime/PR

Valve, Figure 2). Used to

relieve pressure from

gun, hose and tip and to

prime the unit when in OPEN

position. (It is in open position when there is a wider gap between valve handle and cam body.) When in CLOSED position, there is only a very slight gap between handle and body. When closed, the system is pressurized.

●Pressure Control Knob (Figure 3). Used to adjust

pressure. Turn Figure 3 - Pressure

clockwise to Control increase pressure and counterclockwise to decrease it.

●Toggle Switch (Figure 4).

ON OFF

PROCEDURE

1.Make sure the gun trigger lock is engaged and there is no spray tip in the gun. Refer to Figure 5. (Refer to Figure 10 for information on how to lock the trigger lock and the gun's safety features.)

Figure 5 - Engaging trigger lock

To reduce the risk of static sparking,

which can cause fire or explosion, always hold a metal part of the gun firmly against the grounded pail when flushing. (This also reduces splashing.)

2. Pour enough clean, compatible solvent into a large, empty 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 3.

5. Point the gun into the pail and hold a metal part of the gun firmly against the pail. Refer to Figure 6.

6.Disengage the gun safety latch and squeeze the gun trigger. Turn the

ON-OFF Toggle Switch to the "ON" position (Figure 4) and turn Pressure Control Knob (Figure 3) clockwise to increase pressure just enough to start the pump.

7.Turn the Prime/PR Valve to the "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 trigger lock.

9.If you are going to start spraying, place the suction tube into the supply container. Release the gun safety latch and trigger the gun into another empty, metal container, holding a metal part of the gun firmly against the pail and force the solvent from the pump and hose. Engage the gun safety latch until you are ready to spray.

10.If you are going to store the sprayer, remove the suction tube from the solvent pail, holding a metal part of the gun firmly against the pail and force the solvent from the pump and hose. Engage the gun safety latch. Refer to "Storage" Procedure on page 4.

11.Whenever you shut off the sprayer, follow the "PRESSURE RELIEF PROCEDURE" on page 3.

SETTING UP

1.Connect the hose and gun.

a.Remove the plastic cap plug from the outlet tee and screw a conductive or grounded 3000 psi airless spray hose onto fluid outlet.

b.Connect an airless spray gun to the other end of the hose.
