Startup
WARNING
A rope which recoils too quickly may hit someone
and cause serious injury. The rope could also jam
in recoil assembly.
f. Hold the frame of the sprayer with one hand
and pull the starter rope rapidly and firmly.
Continue holding the rope as you let it return.
Pull and return the rope until the engine starts.
g. Open the choke as soon as the engine starts,
except in cold weather. In cold weather, leave
the choke closed for 10 to 30 seconds before
opening it to keep the engine running.
7. Unlock the gun trigger safety.
8. To start the pump:
a. Open the pressure drain valve.
b. Turn the pressure control switch to ON.
c. Turn the pressure control knob about 1/4 turn
from minimum pressure. Run the pump until
fluid is flowing smoothly from the pressure
drain valve, indicating the pump is fully primed.
d. Close the pressure drain valve. Hold a metal
part of the gun firmly against a grounded metal
pail and squeeze the trigger until fluid flows
from the gun.
e. Release the trigger. Lock the gun trigger
safety.
9. If you have not primed the sprayer with paint
yet, move the suction tube to the paint container.
Unlock the gun trigger safety. Trigger the gun into
the water/solvent pail just until paint appears.
Release the trigger and lock the trigger safety.
Repeat for the second gun if two guns are used.
WARNING
To reduce the risk of serious injury from fluid injec-
tion, NEVER operate the spray gun with the tip
guard removed.
10. Install the spray tip in the gun. See the separate
tip instruction manual, 308644, supplied.
11. Adjust the engine speed and pump pressure.
Unlock the gun trigger safety. Trigger the gun onto
a test paper to check the spray pattern and atom-
ization. Turn the pressure adjusting knob until you
get a good pattern. Then slowly lower the throttle
setting as far as you can without changing the
spray pattern.
CAUTION
Always use the lowest needed fluid pressure and the
lowest needed throttle setting, to increase the life of
the sprayer. Higher settings cause excessive clutch
cycling, premature tip wear and premature pump
wear.
CAUTION
Close the black fuel shutoff lever whenever you are
transporting the sprayer to prevent fuel from flooding
the engine.
Keep the sprayer upright and level when operating it
and when transporting it. This prevents crankcase oil
from leaking into the combustion chamber, which
makes startup very difficult.
