How To Level The Mower Housing - Sears 536.270212 Owner's Manual

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 level surface.
2. Check the air pressure in the tires. If the air pressure is incor-
rect, the mower housing will not cut level. Make sure the rear
tires are inflated to 14 psi. (1 BAR) and the front tires to 22 psi.
(1.5 BAR).
3. Move the lever for the attachment clutch to the ENGAGE posi-
tion. Move the lift lever to the middle position.
4. There are two adjustment procedures below that will level the
mower housing.
THE SIDE TO SIDE ADJUSTMENT
There are measuring points on the mower housing indicated by
small round dimples A, B, C, and D shown in Figure 31. To
determine if an adjustment is needed, use a ruler and measure the
distance from the level surface to the bottom of the mower housing
at points C and D. In correct adjustment, the mower housing at
points C and D must be within 1/4" (6 mm) of the same height. If the
difference in the measurement is more than 1/4" (6 mm), adjust as
follows.

housing at points A and B. In correct adjustment, the front of the
mower housing at point A will be 1/8" to 3/8" (3mm to 9mm) lower
than the back of the mower housing at point B. Adjust as follows.

2. Turn the locknut clockwise to raise the front of the mower
housing. Turn the locknut counterclockwise to lower the front
of the mower housing.
