SECTION 6: MAKING ADJUSTMENTS
Handle Height
The mower is shipped with the handle at a higher height
position. To lower the handle height, proceed as
follows.
Remove the starter rope from the rope guide.
Remove the hand knobs, washers and carriage
bolts securing the upper handle to the lower
handle. 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. Press outward on the legs of the
lower handle, and remove it from the mower.
Remove the carriage bolts and wing nuts from the
handle brackets. Press out on the legs of the lower
handle. Remove lower handle from the mower.
Turn the lower handle around so the notches on the
bottom of the lower handle are facing forward as
shown in Figure 12 . Reassemble, placing the
bottom holes in the handle over the weld pins in the
handle mounting bracket. Reattach hardware.

Place the hairpin clips in the inner holes of the weld
pins and replace the carriage bolts and wing nuts

Cutting Height
An adjusting plate and thumb lever at each wheel
position provides cutting height adjustment. Each
adjusting plate has nine height positions.
Simply depress the lever towards wheel and move
it to any of the nine positions for the desired cutting
height. See Figure 13. All four levers on the four
wheels must be placed in the same relative position
for uniform cutting height

Carburetor
Minor carburetor adjustments may be required to
compensate for differences in fuel, temperature,
altitude and load. To adjust carburetor, refer to the
engine manual.
NOTE: A dirty air cleaner will cause an engine to run
rough. Be certain air cleaner is clean and attached to
the carburetor before adjusting carburetor.
WARNING:
Do not at any time make any
adjustment to lawn mower without first
stopping the engine and disconnecting the
spark plug wire.
