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 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.

Installing a Blade 

NOTE: 

When installing certain blades, it may be  

necessary to temporarily remove the  

safety clip.

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.

 

WARNING!

Never operate the C3410 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 combination 

spark plug wrench/screwdriver, tighten 

the bolt firmly in a counter-clockwise 

direction.

7.  Remove the hex wrench.
