Installing A Blade - Shindaiwa 81714 Owner's/Operator's Manual

Installing a Blade

Turn the C3410 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 1.
. 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 C3410 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
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.
