SECTION 7: MAKING ADJUSTMENTS
WARNING: Be sure to disconnect the spark
plug wire and DE-ENERGIZE starter before
performing any adjustments or repairs. DO
NOT attempt any maintenance or service to
the engine and/or mower equipped with the
safety key in the unlocked and/or energized
mode.
WARNING: NEVER assume starter is de-
energized, even if the key is in the locked
position and/or removed from the engine.
ALWAYS de-energize self starter prior to
performing any maintenance or service to the
engine and/or mower. Follow instructions on
the engine and/or machine to de-energize
starter.
Cutting Height Adjustment
There is an adjusting plate and thumb lever at each
wheel position to adjust the cutting height. Each
adjusting plate has nine height positions. Height of cut
will change if you move the thumb lever from one hole
to another.
Simply depress the lever towards wheel and move the
wheel and lever assembly to the desired position. All
wheels must be placed in the same relative position for
uniform cutting height. See Figure 8.
Figure 8
For rough or uneven lawns, move the height
adjustment handles to positions which will give a higher
cutting height. Both front and rear handles must be
placed in the same relative position.
Handle Height Adjustment
Figure 9
Your mower is shipped with the handle in the higher
height position. To lower the handle height, proceed as
follows.
Remove the starter rope from the rope guide.
Remove the upper handle by removing the hand
knobs and carriage bolts. Lay the upper handle out
of the way, being careful not to bend or kink the
cable.
Remove the hairpin clips from the weld pins on the
handle brackets. Press inward on the legs of the
lower handle. Remove lower handle from the
mower.
Turn the lower handle around so the notch on the
bottom of the lower handle is facing forward as
shown in Figure 9. Reassemble, placing the bottom
holes in the handle over the weld pins in the handle
mounting bracket.
Reassemble the upper handle.
Place the hairpin clips in the inner holes in the weld
pins and attach the starter rope as instructed in the
Set-Up Instructions.
