(Optional blade usage)
English
8. Operation (EX2-BC only)
2. How you can reduce the chance of blade thrust:
a. Recognize that blade thrust can happen. By
understanding 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 brush or rocks, fences,
metal, etc
c. Be extra prepared for blade thrust 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 increase the
chance of blade thrust.
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 respective 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.
