Using The Blower
Operating Tips
In the hands of an experienced opera-
tor, the blower can efciently move
a wide variety of debris ranging from
grass clippings to gravel. As a general
rule, operate your blower at the lowest
throttle setting required to get the job
done:
Use low throttle settings when
■
clearing lightweight materials from
around lawns or shrubbery.
Use medium to higher throttle set-
■
tings to move grass or leaves from
parking lots or walkways.
Use full throttle when moving heavy
■
loads such as dirt or snow.
IMPORTANT!
Blower noise increases at higher
throttle settings! Always use the lowest
throttle setting required to get the job
done!
This engine is equipped with a heat
sensor in order to prevent overheat-
ing. If engine overheating occurs,
the engine speed will be reduced to
5,000 RPM, and engine stops after 10
seconds.
CAUTION!
If the engine speed is automati-
cally reduced again after cooling
the engine, please consult with an
authorized servicing dealer.

Mufer
This unit must never be operated with
a faulty or missing spark arrester or
mufer. Make sure the mufer is well
secured and in good condition. A worn
or damaged mufer is a re hazard and
may also cause hearing loss.
Spark Plug
Keep the spark plug and wire connec-
tions tight and clean.
Fasteners
Make sure nuts, bolts, and screws
(except carburetor adjusting screws)
are tight.
Air Filter
The H4 engine that powers your
Shindaiwa model is a hybrid 4-stroke
engine. As a hybrid, the engine is
lubricated by oil mixed with the gaso-
line and air from the carburetor that
moves through and around the inter-
nal parts of the engine in a similar way
that a 2-stroke engine is lubricated.
Without the heavy duty 2-stage air l-
ter equipped on all H4 engines, dust
and dirt could also move through the
engine, decreasing engine life, increas-
ing valve wear and the need for more
frequent valve adjustments. To keep
your H4 engine strong and reliable,
Shindaiwa recommends that you check
and service the air lter as instructed in
the 10-Hour Maintenance section that
follows.
