Adjusting Handle Height
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
cables.
Remove the hairpin clips from the weld pins on the
handle brackets. Refer to Figure 5. 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.
Figure 16
Reassemble the upper handle to the lower handle.
Place the hairpin clips in the inner holes of the weld
pins and attach the starter rope as instructed in the
Assembly section.
Adjusting Cutting Height
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 will
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 be changed when the thumb lever is moved from
one location to another.
Simply depress the lever towards the wheel and
move the lever assembly to desired position. See
Figure 17.
For rough or uneven lawns, move the height
adjustment handles to higher cutting height
position.

Adjusting Carburetor
If the engine is running rough, minor adjustments to the
carburetor may be required to compensate for
differences in fuel, temperature, altitude and load.
NOTE: A dirty air cleaner may cause an engine to run
rough.
Make sure that the air cleaner is clean and attached to
the carburetor before deciding to adjust the carburetor.
To adjust the carburetor, please follow the
recommendations and instructions on carburetor
adjustment in the engine manual.
WARNING: 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.
