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.
• Cut while swinging the upper part of your body from
right to left.
• Always release the throttle trigger and allow the
engine to return to idle speed when not cutting.
• When done always unsnap unit from harness before
taking harness off.
The blade continues to spin after the engine is
turned off. The coasting blade can seriously cut
you if accidentally touched.
• Swing the unit in the same direction as the blade
spins, which increases the cutting action.
• Move forward to the next area to be cut after the
return swing and plant feet again.
• The cutting blade is designed with a second cutting
edge, which can be used by removing the blade,
turning it upside down, and reinstalling it.
Do not sharpen the cutting blade. Sharpening the
blade can cause the blade tip to break off while
in use. This can result in severe personal injury to
yourself or others. Replace the blade.
To reduce the chance of material wrapping around the
blade, follow these steps:
• Cut at full throttle.
• Swing the unit into material to be cut from your right
to your left (Fig. 5-7).
• Avoid the material just cut as you make the return
swing.
Do not clear away cut material with the engine
running or blade turning. To avoid serious per-
sonal injury, turn off engine. Allow the blade to
stop before removing materials wrapped around
the blade shaft.

Operation (continued)
DECORATIVE TRIMMING
Decorative trimming is accomplished by removing all
vegetation around trees, posts, fences, etc.
Rotate the whole unit so that the cutting attachment is
at a 30° angle to the ground (Fig. 5-6).
USING THE CUTTING BLADE
Always wear eye, hearing, foot, body protection
and the strap to reduce the risk of injury when
operating this unit.
Do not use the cutting blade for edging or as an
edger, severe personal injury to yourself or oth-
ers can occur.
Before operating the unit with the cutting blade stand
in the operating position (Figs. 5-4). Refer to Holding
the Trimmer, Pg. 16.
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. The blade has maximum cutting
power at full throttle and is less likely to bind, stall, or
cause blade thrust, which can result in serious per-
sonal injury to the operator or others.
