Although a shoulder strap accessory
is not required for use with a grass
unit, a shoulder strap can increase
operator comfort during extended
periods of operation.
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 internal
parts of the engine in a similar way
that a 2-stroke engine is lubricated.
Without the heavy duty 2-stage air
filter 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.
