SERVICE AND ADJUSTMENT
HOW TO LEVEL THE MOWER HOUSING
If the mower housing is level, the blade will cut easier and the lawn
wi!! 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.
