Starting Up
1.Learn the Functions of the Controls.
PRIME/PRESSURE (PR) RELIEF VALVE is used to prime pump and to relieve pressure from gun, hose and tip.
Prime/Pressure Relief Valve (Prime/PR Valve)
Used to relieve pressure from gun, hose & 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 & body. When closed the system is pressurized. Handle as a loaded firearm!
PRESSURE CONTROL KNOB is used to adjust pressure. Turn clockwise (CW) to increase pressure and counterclockwise (CCW) to
decrease pressure.
2.Prepare the Material
a.Prepare the material according to the material manufacturer's recommendations.
b.Place the suction tube into the material container.
3.Starting the Sprayer
a.Prime/PR Valve must be "OPEN" in the priming position.
b.When you have ensured that the gun safety latch is engaged, attach tip and safety guard.
c.Turn the engine ON/OFF switch to the "ON" position. Pull rope vigorously until engine starts.
d.Turn Pressure Control Knob clockwise to prime the pump.
e.After the pump is primed, turn Prime/PR Valve to the "Closed" position.
f.Turn Pressure Control Knob to the desired spray pressure.
g.Disengage the gun safety latch and you are ready to spray.
4.Adjusting the Pressure
a.Turn the Pressure Control Knob Clockwise to increase pressure and counterclockwise to decrease pressure.
b.Always use the lowest pressure necessary to completely atomize the material.
Note: Operating the sprayer at higher pressure than needed, wastes material, causes early tip wear, and shortens sprayer life.
c. If more coverage is needed, use a larger tip rather than increasing the pressure.
d. Check the spray pattern. The tip size and angle determines the pattern width and flow rate.
Follow the "Pressure Relief Procedure". To reduce the risk of injection, never hold your hand, body, fingers or hand in a rag in front of the spray tip when cleaning or checking for a cleared tip. Always point the gun toward the ground or into a waste container when checking to see if the tip is cleared or when using a
When you spray into the paint bucket, always use the lowest spray pressure and maintain firm metal to metal contact between gun and container.
To stop the unit in an emergency, turn the engine off. Then relieve the fluid pressure in the pump and hose as instructed in the Pressure Relief Procedure.
