Maintenance; Important - Shindaiwa PS344 PowerBroom Owner's/Operator's Manual

Operating continued)
Operating Techniques
Operate the PowerBroom at or near full
throttle with its sweeper fins resting on
the work surface.

IMPORTANT!

It is both tiring and unnecessary to lift
or hold the fins from the work surface
during sweeping.
When sweeping narrow areas such
as sidewalks, the PowerBroom can be
used to throw material directly ahead of
the operator. Clearing wider areas may
require sweeping at an angle to create
windrows to one side of the path being
cleared.
Windrows of lighter materials often
can be combined into one main row or
pile for eventual pickup, while heavy
or bulky material may need to be col-
lected row-by-row.
To pull debris from corners, reverse
sweeper drum rotation by turning the
powerhead over (throttle facing "up").

throttle settings and be aware that
thrown debris may also affect your
footing!

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 fil-
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 filter as instructed in
the 10-Hour Maintenance section that
