Maintenance
Level the Mower Housing
If the mower housing is level, the blade will cut easier
and the lawn will look better.
1. Make sure the unit is on a hard flat surface.
2. Check the air pressure in the tires. If the air pres-
sure is incorrect, the mower housing will not cut
level. The correct air pressure is shown on the side
of the tires.
3. Move the lift lever to the lowest position (see
Figure 28
).
WARNING
Before you make an inspection, adjustment, or
repair to the unit, disconnect the wire to the spark
plug. Remove the spark plug wire to prevent the
engine from starting by accident.
WARNING
The lift lever (3) is spring loaded. Make sure the lift
lever (3) is locked in the lowest position (2).
4. Loosen the left and right adjuster knobs (1) (see
Figure 29
). Push down on each side of the mower
housing. Make sure both sides of the mower hous-
ing are setting on a flat surface. Also, make sure the
lift links are loose and can easily move up or down.
5. Push down on the adjuster knobs and the lift links.
Tighten the left and right adjuster knobs. Make sure
the adjuster knobs are tight. If necessary, use a
wrench to tighten the adjuster knobs. Tighten to
13,5 N-m (10 ft-lbs).
6. Raise the lift lever (1) (see F
Figure 28
).
7. Mow for a short distance. If the height of cut is not
level, repeat the above steps.
