Cutting
(
Fig.

)
○
When cutting, operate engine at over 6500 min
-1
.
Extended time of use at low speed may wear out the
clutch prematurely.
○
Cut grass from right to left.
○
Blade thrust may occur when the spinning blade
contacts a solid object in the critical area.
A dangerous reaction may occur causing the entire
unit and operator to be thrust violently. This reaction
is called blade thrust. As a result, the operator may
lose control of the unit which may cause serious or
fatal injury. Blade thrust is more likely to occur in areas
where it is di
ffi
cult to see the material to be cut.
○
Wear the harness as shown in the
fi
gure. The blade
turns counter-clockwise, therefore, be advised to
operate the unit from right to left for e
ffi
cient cutting.
Keep onlookers out of working area at least 15 m.
NOTE
Press the quick release button or pull emergency
release
fl
ap in the event of emergency.
