HOW TO LEVEL THE MOWER HOUSING
If the mower housing is level, the blade will cut easier and the lawn
will look better.
WARNING: Before you make an inspection, adjust-
ment, 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.
1. Make sure the unit is on a hard flat surface.
2. Check the air pressure in the tires. If the air pressure is incor-
rect, the mower housing will not cut level. The correct air pres-
sure is shown on the side of the tire.
3. Make sure the blade rotation control is in the DISENGAGE
position.
4. Open the cover (see Figure 26).
5. Move the lift lever to the LEVEL ADJUSTMENT position (see
Figure 26).
6. Loosen the front and rear adjuster knobs (see Figure 26 and
Figure 27). Make sure both sides of the mower housing are set-
ting on a flat surface.
7. Make sure that the adjuster plate is loose and can easily move
up or down (see Figure 27).
8. Tighten the front and rear adjuster knobs. Make sure the ad-
juster knobs are tight. If necessary, use a wrench to tighten the
adjuster knobs. Tighten to a torque of 10 foot pounds (13,5
N−m).
9. Raise the lift lever from the LEVEL ADJUSTMENT position to
a CUTTING HEIGHT position (Figure 28).
10. Close the cover.
11. Attach the spark plug wire to the spark plug.
12. Mow for a short distance. If the height of cut is not level, repeat
the above steps.
CAUTION: Do not operate with the mower housing in the
LEVEL ADJUSTMENT position. If you operate in the LEVEL
ADJUSTMENT position, the mower housing and blades can be
damaged.
