NOTE:
When installing certain blades, it may
be necessary 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 T272X
without the safety clip in place!
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 sur-
face of the blade.
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.
Install the bolt guard and then the
blade retaining bolt. Using the combi-
nation spark plug wrench/screwdriver,
tighten the bolt firmly in a counter-
clockwise direction.
Remove the hex wrench.
