Decorative Trimming; Using The Cutting Blade - Troy-Bilt TB490BC Manual Del Operador

DECORATIVE TRIMMING

Decorative trimming is accomplished by removing all
vegetation around trees, posts, fences and more.
Rotate the whole unit so that the cutting attachment is at
a 30° angle to the ground (Fig. 29).

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. 30). Refer to Holding the
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: 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 you are finished, always unsnap the unit from
the harness before taking off the harness.
OPERATING INSTRUCTIONS

WARNING: 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 opposite direction that 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 right to
your left (Fig. 31)
• 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.
