■ Place the product on the right side of your body with
the engine behind and away from your body.
■ Trim grass and weeds in a left-to-right motion with the
line parallel to the ground.
TO ADVANCE THE CUTTING LINE (FIG.7)
Follow these steps to advance the cutting line.
■ Start the trimmer.
■ Tap the bump knob lightly on the ground while the
motor is running. The line will only advance with the
engine at full throttle. Do not hold the bump knob on
the ground.
■ Do not bump the knob on hard surfaces such as
concrete. This may cause damage to the bump knob.
Note:
The line cutting blade on the safety guard will
cut the line to the proper length.
Note:
To help prevent line tangle, tap only once to
lengthen the line. If additional line is required, wait a
few seconds before retapping the bump knob. Do not
allow the line to wear too short. Keep the cutting line
at full length.
OPERATING AS A BRUSHCUTTER (FIG. 8-9)
WARNING
Extreme care must be taken when using blades to
ensure safe operation. Read the safety information for
safe operation using the blade, refer to “Specific Safety
Rules for Brushcutter and Blade Use” earlier in this
manual.
TRI-ARC BLADE
The TRI-ARC blade is suited only for pulpy weeds and
vines. When the blade becomes dull, it can be turned over
to extend the life of the blade. Do not sharpen the TRI-
ARC blade.
Hold the brushcutter with the right hand on the trigger
handle and the left hand on the front handle. Keep a firm
grip with both hands while in operation. Brushcutter should
be held at a comfortable position with the trigger handle
about hip height. Maintain your grip and balance on both
feet. Position yourself so that you will not be drawn off
balance by the kick-back reaction of the cutting blade. If
using a shoulder strap adjust to position the brushcutter
at a comfortable operating position. Shoulder straps
are available as an accessory and may help to reduce
operator fatigue.
Exercise extreme caution when using the blade with this
unit. Blade thrust is the reaction which may occur when
the spinning blade contacts anything it cannot cut. This
contact may cause the blade to stop for an instant, and
suddenly “thrust” the unit away from the object that was
hit. This reaction can be violent enough to cause the
operator to lose control of the unit. Blade thrust may 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. For cutting ease and safety, approach
the weeds being cut from the right to the left. In the event
that an unexpected object or woody stock is encountered,
this could cause the blade thrust reaction.
