CABLE ADJUSTMENT
Push the button down on the blade control lever and measure
the free play at the top of the lever.
If adjustment is necessary:
1. Loosen the lock nuts and move the adjuster up or down as
required.
2. Tighten the lock nuts and recheck free play.
3. Start the engine outdoors. Move the throttle to the FAST
position. Operate the blade control lever. The blades
should engage when you push the lever forward, and the
blades should stop quickly when you release the lever.
INSPECTION
Before inspecting brake or clutch wear, it is important to make
sure the blade control lever free play is correct.
If any measurements are less than the service limit, replace
the driven disc and inspect the clutch spring (P. 4 - 2
).
If the clutch spring is not within specifications, replace the
clutch spring (P. 4 -4
).

With the blade control lever released, measure the distance
between the edge of the brake plate and the indicator.
Replace the disc if below the service limit.
Blades have been removed for clarity.
CLUTCH WEAR
With the blade control lever pushed forward against the
handlebar, use a clean feeler gauge to measure the distance
between the brake plate and the driven disc.
Replace the disc if below the service limit.
