Before operating the unit with the cutting blade, stand in

Trimmer.
Cutting Blade Operating Tips
To establish a rhythmic cutting procedure:
• Plant feet firmly, comfortably apart.
• Bring the engine to full throttle before entering the
material to be cut. At full throttle the blade has
maximum cutting power and is less likely to bind, stall
or cause blade thrust (which can result in serious
personal injury to the operator or others).
WARNING:
spinning blade contacts an object that it does
not immediately cut. Blade thrust can be violent
enough to cause the unit and/or operator to be
propelled in any direction, and possibly lose
control of the unit. Blade thrust can 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.
• Cut while swinging the upper part of your body from
left to right.
• Always release the throttle trigger and allow the engine
to return to idle speed when not cutting.
• When you are finished, always unsnap the unit from
the harness before taking off the harness.
