OPERATING INSTRUCTIONS
USING THE CUTTING BLADE
WARNING:
Always wear eye, hearing, foot, body protection and
the shoulder strap to reduce the risk of injury when operating this unit.
WARNING:
Do not use the cutting blade for edging or as an
edger. Severe personal injury to yourself or others can result.
Before operating the unit with the cutting blade, stand in the operating
position (Fig. 21). Refer to Holding the Trimmer.
Cutting Blade Operating Tips
WARNING:
Blade thrust may occur when the 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.
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).
• 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.
• Swing the unit in the opposite direction as the blade spins, which
increases the cutting action.
• After the return swing, move forward to the next area to be cut and plant
your feet again.
• The cutting blade is designed with a second cutting edge. You can use it
by removing the blade, turning it upside down and reinstalling it.
To reduce the chance of material wrapping around the blade, follow these steps:
WARNING:
The blade continues to spin after the engine is turned
off. The coasting blade can seriously cut you if accidentally touched.
• Cut at full throttle.
• Swing the unit into material to
be cut from your left to your
right (Fig. 22).
• Avoid the material just cut as
you make the return swing.
WARNING:
Do not clear away any cut material with the engine
running or blade turning. To avoid serious personal injury, turn off
the engine. Allow the blade to stop before removing materials
wrapped around the blade shaft.
