engine speed is too low, or the blade cuts too
deep into weeds. It is important to adjust the
engine speed and cutting depth accordingly to
the challenge.
WARNING
If the grass or any other object gets caught on
the blade, or if the unit starts to shake, vibrate or
the engine turns off. Thoroughly check the unit
before using it again and change the blade if it has
been damaged. Always turn off the engine before
attempting to check the blade and removing any
objects that are caught or entangled on the blade.
8.4 OPERATION
1. Check the bolt to fasten the blade and be sure
the bolt has no fault, and no abrasion.
2. Be sure that the blade and the holder have been
fastened according to instruction and that the
blade turns smoothly without abnormal noise.
3. To use the shoulder strap, hang the unit on your
right side. Adjust the strap length so the cutting
head becomes parallel to the ground
WARNING
8.4.1 CONTROLLING BLADE BOUNCE
Kick out can cause serious personal injury. Read this
section carefully to manage and understand what
causes kick outs, and how you can reduce it from
happening to remain in control of the unit if it does
occur.
8.4.2 WHAT CAUSES KICK OUT:
Kick out occurs when the moving blade makes con-
tact with an object that cannot be cut. The contact
causes the blade to stop for an instant and suddenly
move or “bounce” away from the object that was hit.
8.4.3 HOW YOU CAN REDUCE THE
CHANCE OF KICK OUT:
1. Recognize that kick out can happen by
understanding and knowing about bounce to
eliminate the element of surprise.
2.
Cut fibrous weeds and grass only. Do not let the
blade make contact with materials it cannot cut
such as hard, woody vines and bushes or rocks,
fences, metal, etc.
3. Be prepared for bounce if you must cut where
you cannot see the blade making contact such
as in areas of dense growth.
4. Keep the blade sharp. A blunt blade increases
the chance of bounce.
5.
Avoid feeding the blade too rapidly. The blade
can bounce away from material being cut if the
blade is fed faster than its cutting capability.
6. Cut only from your right to your left.
7. Keep your path in advance clear of material
that has been cut and other debris.
8.4.4 HOW YOU CAN MAINTAIN THE
BEST CONTROL:
1.
Keep a good firm grip on the unit with both
hands. A firm grip can neutralize bounce and
keep your right and left hands completely
around their respective handles.
2. Keep both feet spread apart in a comfortable
stance and yet braced for the possibility that
the unit could bounce. Do not overreach. Keep
firm footing and balance.
