REAR DEFLECTOR
The rear deflector, attached between the rear wheels of
your mower, is provided to minimize the possibility that
objects will be thrown out of the rear of the mower into the
operator mowing position. If the deflector becomes dam-
aged, it should be replaced.
ENGINE
CARBURETOR
The carburetor has been preset at the factory and adjust-
ment should not be necessary. However, minor adjust-
ment may be required to compensate for differences in fuel,
temperature, altitude or load.
The air filter must be assembled to the carburetor when
running engine.
Best carburetor adjustment is obtained when fuel tank
is 1/4 full.
In order for the engine to run, the operator presence
control bar must be held in the operating position.
Therefore, and assistant will be required to hold the
control bar in the operating position when making final
adjustment to the carburetor.
See the adjustment section of your engine manual for
further instructions.

increase engine speed as it may result in personal injury.
If you believe the engine is running too fast or too slow, take
your lawn mower to an authorized engine service center for
repair and adjustment.

control, see the adjustment section of your engine manual.
