Installing a Blade
Turn the C2510 upside down so the gear
case output shaft is facing UP and remove
the shaft bolt, bolt guard and holder B from
the gear case shaft.
1. Align the hole in blade holder A with
the matching hole in the gear case
flange and then temporarily lock the
output shaft by inserting a hex wrench
through both holes. See Figure 12.
2. Slide the safety clip off-center. See
Figure 13.
3. Fit the blade over the safety clip and
then center it over the flange on holder
A. See Figure 14.
CAUTION!
Install the blade so its printed surface
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.
NOTE:
When installing certain blades, it may be
necessary to temporarily remove the safety clip.
4. Lock the blade in place by centering
the safety clip on the output shaft.
See Figure 14.
WARNING!
Never operate the C2510 without the
safety clip in place!
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.
