Figure 10

A height adjustment lever at each wheel provides cutting height adjustment. Each adjuster has nine height positions. Height of cut will be changed when the lever is moved from one position to another.

Depress the lever towards wheel and move the wheel and lever assembly to desired position. Refer to Figure 11.

To raise the height, push the lever towards the front of the mower on both front wheels, and push the lever toward the back of the mower on the rear

wheels.

All wheels must be placed in the same relative position. For rough or uneven lawns, move the wheels to a position which will give a higher cutting height.

Figure 11

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 cable ties that hold the control cable to the upper and lower handles.

Remove the upper handle by removing the wing nuts 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. Press out on the legs of the lower handle and remove the 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 11. 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.

Place the hairpin clips in the inner holes in the weld pins and attach the starter rope as instructed in the Assembling Your Lawn Mower section.

SECTION 8: MAINTAINING YOUR LAWN MOWER

NOTE: When tipping the unit, empty the fuel tank, keep the engine’s spark plug side up. Never tip the mower more than 90 degrees and do not leave the mower tipped for a sustained length of time. Oil can drain into the upper part of the engine causing starting problems.
