WARNING!
Never repair a damaged blade
■
by welding, straightening, or by
modifying its shape. An altered
blade may break during opera-
tion, resulting in serious per-
sonal injury.
Blades are not interchangeable
■
between Shindaiwa edgers and
unit/brushcutter models. Oper-
ating any unit with a blade or
attachment not approved for the
unit can be hazardous and may
cause serious injury.
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.
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 lubri-
cated. Without the heavy duty 2-stage
air lter equipped on all H4 engines,
dust and dirt could also move through
the engine, decreasing engine life,
increasing 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.
