NOTE:
When installing certain blades, it may be nec-
essary to temporarily remove the safety clip.
CAUTION!
Install the blade so its printed sur-
face is visible to the operator when
the brushcutter is in the normal
operating position.
WARNING!
The blade must fit flat
against the holder flange.
The blade mounting hole must be
centered over the raised boss on
blade holder A.
WARNING!
Never operate the T231X
without the safety clip in
place!
4. Lock the blade in place by centering
the safety clip on the output shaft. See
Figure 14.
IMPORTANT!
The machined recess in holder B must
completely surround the safety clip, and
both holders must be flat against the
surface of the blade.
5. Install blade holder B on the output
shaft. See Figure 15. The recess in
the holder must completely cover the
safety clip, and must fit tightly against
the blade.
6. Install the bolt guard and then the
blade retaining bolt. Using the com-
bination spark plug wrench/screw-
driver, tighten the bolt firmly in a
counter-clockwise direction.
