Know Your Controls
Know Your Controls
The ON/OFF power switch controls the main power to your sprayer.
The Pressure Control knob increases or decreases the pressure and flow of the paint.
The Prime/Spray Valve directs the fluid to either the Drain Tube or the hose and gun. It is used to prime the sprayer, which means to evacuate the air out of the pump, hose, and gun.
Your gun will not spray if there is air in the system. It is necessary to prime the pump, hose, and gun any time air enters the Suction Tube.
The Spray Tip is the key to airless spray technology. High pressure paint pumped through the very small hole in the Spray Tip comes out as a spray.
The Spray Tip has the ability to be reversed and quickly clear clogs.

High-pressure spray is able to inject toxins into the body and cause serious bodily injury. Do not stop leaks with hand or rag.
Fill Pump (Prime Pump)
The Prime/Spray Valve directs the fluid to either the Drain Tube or the hose and gun. It is used to prime the sprayer, which means to evacuate the air out of the pump, hose, and gun.
Your gun will not spray if there is air in the system. It is necessary to prime the pump, hose, and gun any time air enters the suction tube.
1.Move Suction Tube to paint pail and submerge Suction Tube in paint.
2.Turn ON/OFF switch to ON position.
3.Wait to see paint coming out of Drain Tube.
4.Turn ON/OFF switch to OFF position.
NOTE: If paint does NOT flow up the Suction Tube and out the Drain Tube, see Flush Storage Fluid, page 15.
Fill Gun and Hose
1.Rotate Spray Tip to UNCLOG position and ensure the Spray Tip Guard is tight.
2.Hold gun against waste pail. Point gun into waste pail.
a.Disengage trigger lock (A).
b.Pull and hold gun trigger (B).
c.Turn Prime/Spray Valve horizontal to SPRAY position (C).
d.Turn ON/OFF switch to ON position
(D).
3.Trigger gun into waste pail until only paint comes out of the gun.

Start Up
4.Release trigger. Engage trigger lock.
High-pressure spray is able to inject toxins into the body and cause serious bodily injury. Do not stop leaks with hand or rag.
NOTE: Inspect for leaks. If leaking occurs, perform Pressure Relief Procedure, page 14, then tighten all fittings and repeat Fill Pump (Prime Pump), page 16.
5.Transfer Drain Tube to paint pail and clip to Suction Tube.
6.Rotate Spray Tip back to SPRAY position and ensure the Spray Tip Guard is tight.
Refilling Paint Pail
When the paint pail runs low and the gun stops spraying, refill the paint pail and repeat the Fill Pump (Prime Pump) procedure, then the Fill Gun and Hose procedure.
You are now ready to spray!
NOTE: It is normal for the motor to stop once the sprayer is primed and under pressure. If the motor continues to run, the sprayer is not primed. Repeat the Fill Pump (Prime Pump) and Fill Gun and Hose processes.
Blockages
If paint does not come out of the gun, or if performing pressure relief procedure and you suspect pressure has not been fully relieved:
1.VERY SLOWLY loosen the hose connection to the gun and disconnect the airless spray hose from the gun.
2.Turn Prime/Spray Valve horizontal to SPRAY position.
3.While holding hose firmly, point end of hose into paint pail and turn ON/OFF switch to ON position.
a.If fluid does not flow out of hose, replace the hose and continue to step 4.
b.If fluid flows out of hose, see Clean the Gun and Gun Filter, page 27.
4.Reassemble the hose and gun, and repeat Fill Gun and Hose, page 16.
