WARNING
CONTROLLING BLADE BOUNCE
Blade thrust can cause serious personal injury. Care-
fully study this section. It is important that you un-
derstand what causes blade thrust, how you can re-
duce the chance of blade thrust and how you can
remain in control of the unit if blade thrust does oc-
cur.
1. What causes blade thrust:
• blade thrust can occur when the moving blade
contacts an object that it cannot cut. This contact
causes the blade to stop for an instant and then
suddenly move or "bounce" away from the object
that was hit. The operator can lose control of the
unit and the blade can cause serious personal
injury to the operator or any person nearby if the
blade contacts any part of the body.
2. How you can reduce the chance of blade thrust:
a. Recognize that blade thrust can happen. By un-
derstanding and knowing about bounce, you can
help eliminate the element of surprise.
b. Cut fibrous weeds and grass only. Do not let the
blade contact materials it cannot cut such as hard,
woody vines and bushes or rocks, fences, metal,
etc.
c. Be extra prepared for bounce if you must cut where
you cannot see the blade making contact such as
in areas of dense growth.
d. Keep the blade sharp. A dull blade increases the
chance of bounce.
e. 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.
f. Cut only from your right to your left.
g. Keep your path of advance clear of material that
has been cut and other debris.
3. How you can maintain the best control:
a. Keep a good, firm grip on the unit with both hands.
A firm grip can help neutralize bounce. Keep your
right and left hands completely around the respec-
tive handles.
b. 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.
