Startup
Before you start the sprayer
1. See Flushing on page 15 to determine if you should
flush the sprayer .
2.
Be sure the gas tank is full.
3. Check the engine oil level.
NOTE: The
engine stops automatically , or will not start,
if it is low on oil. If you try to start it again without adding
more oil, a red light near the engine on/off switch glows
as
you pull the starter rope.
4. Be sure the spark plug cable (G) is firmly pushed
onto the plug.
Startup
NOTE: Refer to Fig. 4 as you start the sprayer .
1. When
starting a sprayer that IS NOT PRIMED, re -
move
the spray tip.
2. If a secondary hose and gun is not installed, be
sure
the cap (56) is securely plugging the secondary
outlet fitting.
3. Place the suction tube into the paint, water or
solvent container, depending on whether you are
flushing
or are ready to spray .
4. Open the black fuel shutoff lever (H) by pushing
it
in the direction of the arrow .
CAUTION
Never try to start the engine unless fluid pressure is
relieved and the pressure control switch (A) is OFF.
Trying
to start the engine when it is pressurized could
damage the recoil system.
5. Turn the pressure control switch (A) to OFF.
6. To start the engine:
a. Turn
the pressure adjusting knob (B) fully coun -
terclockwise
to the lowest pressure setting.
b. Slide the metal throttle lever (K) away from the
fuel
tank to maximum position (fully left).
c. If the engine is cold, close the choke by moving
the gray lever (J).
If the engine is warm, close the choke by moving
the gray lever only half way or not at all.
d. T urn the engine switch (L) to ON.
WARNING
A rope which recoils too quickly may hit someone and
cause serious injury . The rope could also jam in recoil
assembly.
e. 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 re -
turn
the rope until the engine starts.
f. Open the choke as soon as the engine starts, ex -
cept in cold weather. In cold weather, leave the
choke
closed for 10 to 30 seconds before open -
ing
it to keep the engine running.
7. Disengage the trigger safety latch (N).
8. To start the pump:
a. Open the pressure drain valve (53).
b. T urn the pressure control switch (A) to ON.
c. Turn the pressure control knob (B) 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 (53). 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. Engage the trigger safety
latch (N).
9. If
you have not primed the sprayer with paint yet,
move the suction tube to the paint container . Release
the trigger safety latch. Trigger the gun into the wa-
ter/solvent pail just until paint appears. Release the
trigger and engage the trigger safety latch. Repeat
for
the second gun if two guns are used.
WARNING
To reduce the risk of serious injury from fluid injection,
NEVER operate the spray gun with the tip guard re-
moved.
10. Install the spray tip in the gun. See the separate
tip
instruction manual, 307–848, supplied.
11. Adjust the engine speed and pump pressure. Re -
lease
the trigger safety latch (N). T rigger the gun onto
test paper to check the spray pattern and atomiza-
tion. Turn the pressure adjusting knob (B) until you
get
a good pattern. Then slowly lower the throttle (K)
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
and premature tip and pump wear .
Close the black fuel shutoff lever (H) 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 dif ficult.
CAUTION
