SECTION 8: ADJUSTMENTS
WARNING: Do not at any time make
any adjustment to lawn mower without first
stopping engine and disconnecting spark
plug wire.
CUTTING HEIGHT ADJUSTMENT
An adjusting plate and lever at each wheel position
provides cutting height adjustment. Each adjusting
plate has nine height positions. Height of cut will be
changed when the lever is moved from one position
to another. Simply depress the lever towards wheel
and move wheel and lever assembly to desired
position. All wheels must be placed in the same
relative position. See Figure 10.

THROTTLE CONTROL ADJUSTMENT
NOTE: Your unit may be a constant speed engine,
which is set at full throttle for best performance. This
engine requires no throttle adjustment.
If you have a unit with a the throttle control which
needs adjustment or if it has been replaced, adjust
as follows.
1. Remove the screw shown in Figure 11. Remove
the cable clamp from the cable.
NOTE: If you have a Tecumseh engine, simply
loosen the screw shown in Figure 12 so the cable
will move freely beneath the clamp. It is not
necessary to remove the screw and clamp
completely.
2. Push the throttle control lever on the handle all
the way forward as far as it will go, then back it
off one “click.” Make certain the throttle control
lever remains in this position.
3. Push the control lever on the engine as far
toward the rear of the engine as it will go.
Secure the cable in this position with the cable
clamp and screw.
