2. Place the pump or suction tube into the material
container.
3. Start the sprayer.
a. Prime/PR Valve must be “OPEN” in the prim-
ing position.
b. Pressure Control Knob must be in low pres-
sure.
c. Turn the engine ON/OFF switch to ON.
d. Move the choke toward the closed position.
e. Move the throttle lever slightly to the left.
f. Turn the fuel valve ON. Pull the start rope. Pull
the engine over against compression stroke
and then let the rope rewind slowly into the
starter. Pull firmly and rapidly to start the
engine. Do NOT drop the rope. Hold on to the
handle while rewinding, or the rope may
rewind improperly and jam the assembly. If
the engine does not start, open the choke all
the way and continue cranking.
g. After the engine is warm, gradually close the
choke lever, raise the RPM of engine slightly
by moving throttle to the left. Close the prime
valve.
h. Point the gun into the metal pail and hold a
metal part of the gun firmly against the pail.
Maintain firm metal to metal contact between
gun and container.
i. Disengage the gun trigger lock and squeeze
the trigger. At the same time, slowly turn the
pressure control knob clockwise, just enough
to move liquid at low pressure.
4. Prime the Pump
a. Allow pump to operate until paint comes from
gun.
b. Release the trigger and engage the gun trig-
ger lock.
c. Turn Prime Valve OPEN to the prime position
ensuring the pressure is released from the
system.
d. Turn Pressure Control Knob to minimum pres-
sure.
e. Install spray tip onto gun.
f. Close the prime valve to the pressure position.
g. Turn the pressure control knob to desired
spray pressure.
h. Disengage the gun safety lock and you are
ready to start spraying.
Adjusting the Pressure
1. Turn the Pressure Control Knob Clockwise to
increase pressure and counterclockwise to
decrease pressure.
2. Always use the lowest pressure necessary to com-
pletely atomize the material.
3. If more coverage is needed, use a larger tip rather
than increasing the pressure.
4. Check the spray pattern. The tip size and angle
determines the pattern width and flow rate.
Shutdown
1. Relieve Pressure, page 6.
2. Clean the tip and gun as recommended in the sepa-
rate Gun Manual supplied with the gun.
3. If spraying water-based material or a material that
could harden in the sprayer overnight, flush the
sprayer after use. See Flushing, page 7.
• 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 self cleaning tip.
• When you spray into the paint bucket, always use
the lowest spray pressure and maintain firm metal
to metal contact between the gun and container.
• To stop the unit in an emergency, turn the engine
off. Then relieve the fluid pressure in the pump and
hose. See Pressure Relief Procedure, page 6
