To spray

WARNING
• Please use correctly, observing the precautions in
this manual.
• Before lifting the sprayer onto your back, check that the
sprayer tank cap and fuel tank cap 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 fl uid or fuel
may leak out through the air holes in the cap. When
using, always try to maintain an upright posture.
IMPORTANT
• If the sprayer 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
spraying effi ciency is sometimes impaired owing to
insuffi cient pressure.

carrying.
