Introductions
The Shindaiwa 502s chain saw is
designed and built to deliver superior per-
formance and reliability without compro-
mise to quality, comfort, safety, or durabil-
ity. Shindaiwa high performance engines
represent the leading edge of 2-cycle
engine technology, and deliver exception-
ally high power at remarkably low dis-
placement and weight. As a professional
owner/operator, you’ll soon discover why
Shindaiwa is simply in a class by itself.

WARNING! Chain saws can be
dangerous! Careless or improper
use can result in serious or fatal
injury to the operator or others.
Read and follow the Operator’s
Manual. Failure to do so could
result in serious injury.
Wear eye and hearing protec-
tion at all times during the oper-
ation of this unit.
Always hold the saw with both
hands.
Beware of Kickback! Kickback can
occur whenever the tip of the guide
bar touches an object while the saw
is operating. Kickback may force the
bar up and back toward the opera-
tor with a lightning-fast reaction!
Never let the guide bar tip come
in contact with any object.
Pinching the saw along the top of
the guide bar may force the bar
rapidly back toward the operator.
Pinching can occur whenever wood
closes in around the moving chain.
