HOW TO ADJUST THE BLADE ROTATION CONTROL
A
ARNING: To prevent an injury, the blade rotation
control must operate correctly.
In normal usage, the blade rotation control
will not require an
adjustment. However, if the cutting performance decreases or the
quality of cut is poor, make the following changes.
1.
When you mow, make sure the throttle control in in the FAST
position.
2.
Move the blade rotation controlto the DISENGAGE position
(Figure 19).
3.
Stop the engine. Disconnect the wire from the spark plug.
6.
Attach the wire to the spark plug. Mow for a short distance and
again check the quality of cut. If necessary, move the blade
drive spring to the bottom hole.
7.
Again check the quality of cut. If the quality of cut has not im-
proved, replace the mower drive belt. See =How To Replace
The Mower Drive Belt'. If replacing the belt does not correct the
problem, take the unit to an authodzed service center.

tion. Stop the engine. Disconnect the wire from the spark plug.
Check the operation ofthe blade brake. Rotate the pulleys with
your hand. Make sure the brake pads are pressed tightly
against the pulleys (Figure 21).
