Blade Engagement Cable
If the blade won't cut, or seems to slip in
heavy material, check the blade engagement
cable. Remove the black belt guard and
measure the length of the blade clutch spring
(the spring that attaches the cable to the
blade clutch) (Figure 31). When the blade is
engaged (lever pulled back) the spring
should measure 3-1/2" to 3-3/4".
Note: Do not adjust the spring longer than
3-3/4".
Tools Needed:
· 1/2" open-end wrench
!
WARNING: Always remove the spark
plug wire before servicing your machine.
1. On the right handlebar there is a bracket
with two nuts (one on each side) for
adjusting the blade engagement cable
(Figure 32). Loosen the nuts and push
the threaded cable housing down about
1/8" at a time into the bracket. Check the
spring measurement again and adjust as
needed.
2. Retighten the nuts.
Transmission
The transmission is maintenance-free and
does not need additional lubrication.

2. Rotate the tire so the key slot is facing
upwards.
3. Use the screwdriver to remove the U-
shaped lock ring (Figure 33), remove the
washer and slide the wheel off.
