4. Turn Pressure Control Knob counter clockwise to
lowest setting.
5. Open the prime valve to the open - “Priming Posi-
tion”. This will allow an easy start.
6. Turn the engine ON/OFF switch to ON.
7. Move the choke toward the closed position.
8. Move the throttle lever slightly to the left.
9. 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.
10. After the engine is warm, gradually close the choke,
raise the RPM of engine slightly by moving throttle
to the left. .
11. 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.
12. 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. Close the prime spray valve.
13. Allow the pump to operate until clean solvent comes
from the gun.
14. Release the trigger and engage the gun trigger lock.
15. If you are going to start spraying, place the pump or
suction tube into the supply container. Release the
gun trigger lock and trigger the gun into another
empty, metal container, holding a metal part of the
gun firmly against the metal pail, forcing the solvent
from the pump and hose. When paint starts coming
from gun, turn pressure control knob to minimum
pressure, place prime valve in prime (open) position
and engage the gun trigger lock.
16. If you are going to store the sprayer, remove the
suction tube or pump from the solvent pail, force the
solvent from the pump and hose. Engage the gun
trigger lock. See Storage, 9.
