• Keep the J-handle between the operator and cutting
attachment or blade at all times.
• NEVER cut with the cutting blade located over 30

occur without warning if the blade snags, stalls or
binds. This is more likely to occur in areas where it is
difficult to see the material being cut.

anything thicker than 1/2 inch or a violent kickback
could occur.
• Do not attempt to touch or stop the blade when it is
rotating.
• A coasting blade can cause injury while it continues to
spin after the engine is stopped or the throttle trigger
is released. Maintain proper control until the blade has
completely stopped rotating.
• Do not run the unit at high speed when not cutting.
