WARNING
INJECTION HAZARD
T
o reduce the risk of serious injury from
fluid injection, never operate the spray
gun with the tip guard removed.
12. Install the spray tip in the gun.
See the separate

-
tion. T
urn pressure adjusting knob until you get a
good pattern. 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.
Close
the black fuel shutof
f 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 dif
ficult.
