SAFETY FEATURES
Numbers preceding the descriptions correspond with the numbers above to help you locate the safety feature.
2. LOW KICKBACK SAW CHAIN helps significantly reduce kickback, or the intensity of kickback, due to specially
designed depth gauges and guard links.
4. SPARK ARRESTER SCREEN retains carbon and other flammable particles over 0.023 inches (0.6mm) in size from
engine exhaust flow. Compliance with local, state and federal laws and/or regulations governing the use of a spark
arrester screen is the user's responsibility. See Safety Information for additional information.
5. CHAIN BRAKE LEVER / FRONT HAND GUARD helps protects the operator's left hand in the event it slips off the
front handle while the unit is running.
CHAIN BRAKE is designed to reduce the possibility of injury due to kickback by stopping a moving saw chain in
milliseconds. It is activated when pressure is applied to the chain brake lever, as in the event of the operator's hand
striking the lever during kickback.
10. STOP SWITCH immediately stops the engine when moved to the STOP position. The stop switch must be pushed
to the RUN position to start or restart the engine.
11. SAFETY LATCH prevents accidental acceleration of the engine. The throttle control trigger (20) cannot be squeezed
unless the safety latch is depressed.
21. CHAIN CATCHER reduces the danger of injury in the event the saw chain breaks or derails during operation. The
chain catcher is designed to intercept a whipping chain.
