Installation of cutting blade (Fig. 13)
When installing a cutting blade, make sure that there are no
cracks or any damage in it and that the cutting edges are
facing the correct direction.
Align the notch hole of the cutter holder with the hole on
the gear case cover and insert the Allen wrench to stop
turning. Turn the fi xing nut clockwise and remove the fi xing
nut, protection cover, cutter holder cap, and toothed lock
washers.
The installation of the cutting blade is as follows: insert the
Allen wrench into the notch hole of the cutter holder and
the hole on the gear case. Then, install the cutting blade
(check the installing direction, as referring to Fig. 14), the
cutter holder cap, protection cover and toothed lock washers
onto the cutter holder in this order. Finally, tighten the fi xing
nut with the combi box spanner with a tightening torque of
22±2 N · m. Please note that the fi xing nut has left-handed
threads (clockwise to loosen/counter-clockwise to tighten).
(Fig. 13)
CAUTION
○ When installing the cutting blade, set its center hole to
the convex part of the cutter holder and hold it with the
concave surface of the cutter holder cap. Then, tighten
the fi xing nut to prevent the cutting blade from being
eccentric. (Fig. 13)
After installing the cutting blade, be sure to remove the
Allen wrench and Combi box spanner.
○ Before operation, make sure the blade has been properly
installed. (Fig. 15)
○ Before operation, check the cutter holder cap under the
cutting blade for wear or cracks. If any damage or wear
is found, replace it, as it is an article of consumption.
NOTE
○ The blade must be retained with a new cotter pin each
time installed. (Fig. 13)
○ When installing or removing a blade, make sure to wear
gloves and place the blade cover over the blade.
CAUTION
Check a nut cover for wear or cracks before operation. If
any damage or wear is found, replace it, as it is an article
of consumption.
WARNING
○ When installing a cutting blade, make sure that there are
no cracks or any damage in it and that the cutting edges
are facing the correct direction.
○ Remove any surface grit from blade installation fi ttings.
Failure to do so may result in the loosening of nuts.
○ The protrusion of the cutter holder may become
misaligned with the blade while tightening nut. Before
operation, make sure the blade has been properly
installed. (Fig. 15)
○ Rotate the blade by hand and make sure there is no
rocking or abnormal noise. Rocking may cause abnormal
