SAFETY FEATURES
•
LOW-KICKBACK SAW CHAIN
significantly reduces the chance of kickback and the intensity of kickback, due to specially designed
depth gauges and guard links.
•
The
SPARK ARRESTER SCREEN
retains carbon and other flammable particles over 0.023 inches (0.6mm) in size from the 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. Refer to
Spark Arrestor Note
in the
Safety
section for additional information.
•
The
CHAIN BRAKE LEVER / FRONT HAND GUARD
helps protects the operator’s left hand if it slips off the front handle while the unit is
running. The chain brake lever is also used to manually engage the chain brake.
•
The
CHAIN BRAKE
reduces the chance of injury if kickback occurs, by stopping the saw chain in milliseconds. The chain brake is
designed to engage automatically in response to kickback. The chain brake can also be activated by pushing the chain brake lever
forward, either intentionally or if the operator’s hand strikes the lever during kickback.
•
The
ON/OFF SWITCH
immediately stops the engine when moved to the OFF position. The On/Off switch must be moved to the On
position to start the engine.
•
The
THROTTLE LOCKOUT
prevents accidental acceleration of the engine. The throttle control cannot be squeezed unless the throttle
lockout is depressed.
•
The
CHAIN CATCHER
reduces the chance of injury if the saw chain breaks or derails during operation. The chain catcher is designed to
intercept a whipping chain.
