Installation of cutting blade (Fig.1-10,10B)
(If so equipped)
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.
NOTE!
When installing cutter holder cap (1), be sure to
set concave side upward.
Insert the allen wrench (2) into the hole of the
angle transmission in order to lock the cutter
holder (3). Please note that the cutter fixing bolt
or nut (4) has left-handed threads, (clockwise to
loosen/counter-clockwise to tighten). Tighten the
fixing bolt or nut with the box wrench.
NOTE!
If your unit is of a nut securing type and
equipped with a cotter pin, the blade must be
retained with a new cotter pin (5) each time
installed. (Fig. 1-10C)
CAUTION!
Before operation, make sure the blade has been
properly installed.
CAUTION!
If your unit is equipped with protection cover
under a cutting blade, check it for wear or cracks
before operation. If any damage or wear is found,
replace it, as it is an article of consumption.
