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).
CAUTION:
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 left to
right
• Always release the throttle trigger and allow the engine to
return to idle speed when not cutting.
WARNING:
The blade continues to spin after the
engine is turned off. The coasting blade can
seriously cut you if accidentally touched.
• 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 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.
WARNING:
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 left to
your right (Fig. 25)
• Avoid the material just cut as you make the return swing
CAUTION:
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.
NOTE: Please read the California/EPA statement that
came with the unit for a complete listing of terms and
coverage for the emissions control devices, such as the
spark arrestor, muffler, carburetor, etc.
WARNING:
To prevent serious injury, never
perform maintenance or repairs with unit running.
Always service and repair a cool unit. Disconnect the
spark plug wire to ensure that the unit cannot start.
