SECTION 8: MAKING ADJUSTMENTS
Adjusting HandleHeight
Your mower is shipped with the handle in the higher
height position. To lower 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 upper handle out of
the way, being careful not to bend or kink cables.
Remove the hairpin clips from the weld pins on the
handle brackets. Refer to Figure 4. Press out 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 16. Reassemble, placing the
bottom holes in the handle over the weld pins in the
handle mounting bracket.
Reassemble the upper handle to the lower handle.
Insert hairpin clips in the inner holes of the weld
pins and attach the starter rope as instructed in the
"Assembling Your Lawn Mower" section.

IMPORTANT: All wheels must be placed in the same
relative position. For rough or uneven lawns, move the
height adjustment lever to a higher position. This wilt
help stop scalping of the grass.
An adjusting plate and thumb lever at each wheel
position provides cutting height adjustment. Each
adjusting plate has nine height positions. Height of cut
will change when you move the thumb lever from one
position to another.
Simply depress the lever towards the wheel and
move the lever assembly to desired position. See
Figure 17.

NOTE: A dirty air cleaner may cause an engine to run
rough too. Make sure that the air cleaner is clean and
attached to the carburetor before deciding to adjust the
carburetor.

If any adjustments are made to
the engine (e.g. carburetor) while the engine is
running, keep clear of all moving parts. Be
careful of heated surfaces like the muffler.
To adjust carburetor, please follow the engine manual.
