3. Place the sprayer in a stable location, and pull the
starter knob with the right hand while holding the
chemical tank down with the left hand. The starter knob
should first be pulled out lightly, then, when resistance
is felt, pulled more swiftly and vigorously.
IMPORTANT
• Do not pull the rope out completely or release the knob
so that the rope returns, as this can cause starter mal-
function.
4. Once the engine has started, gradually open the
choke, warm up at low speed for 1-2 minutes, then
return the throttle lever to the "slow" position.
IMPORTANT
• If the rope is pulled continuously with the choke
closed, the spark plugs may become flooded and the
engine may fail to start. If so, you should first remove
the spark plugs and dry the electrodes, then repeat
the starting procedure.
■
Stopping engine
WARNING
• Stop the engine immediately in the event of an emergency.
1. Lower the throttle lever fully and cool the engine down
for 1-2 minutes at low speed.
2. Hold down stop switch on the left side of the sprayer
frame until the engine has come to a complete stop .
IMPORTANT
• Except for an emergency, avoid stopping the engine
while pulling the throttle trigger.
■
Spraying
WARNING
• Please use correctly, observing the precautions in this
Manual ("For Safe Operation", p5 to 7).
• Before lifting the sprayer onto your back, check that
the chemical tank and fuel tank caps are tightly closed.
• When spraying, do not point the nozzle at your face,
or at other people, animals, etc.
• If the sprayer is tilted too much, chemical fluid or fuel
may leak out through the air holes in the cap. When
using, always try to maintain an upright posture.
IMPORTANT
• If the chemical tank becomes empty while spraying,
reduce the engine to low speed immediately. Empty
running of the engine may cause the spray pump to
break.
• Please avoid using multiple nozzles, jet nozzles, or
other nozzles that give a large spray volume, as spray-
ing efficiency is sometimes impaired owing to insuffi-
cient pressure.
