CHECK OIL LEVELĊMaintain oil level between
ADD and FULL range as shown on dipstick (Fig. 4).
CUTTING AND BAGGINGĊBest results are
achieved when only about 1/3 of the grass blade is
cut. If long grass must be cut, use highest height-
of-cut setting (E) for first mowing. Then recut the
grass at a more normal setting. If too long of grass is
cut, mower may plug and cause engine to stall.
When cutting in dry, dusty conditions move the
throttle to a slower speed to reduce the amount of
dust generated by mower.
SHARP BLADEĊBegin each cutting season with a
sharp blade. Periodically file down nicks.
CONTROLSĊThrottle, self-propel control bail (self-
propelled model only), blade control bail and recoil
starter are on upper handle (Fig. 5).

sired.
SELFĆPROPEL OPERATION (selfĆpropelled modĆ
el)ĊTo selfĆpropel the mower, squeeze selfĆpropelled
control bail against handle and hold (Fig. 8). To stop
self-propelled drive, release selfĆpropelled control
bail (Fig. 9).

The drive wheels are equipped with freewheelĆ
ing clutches which enable the mower to be pulled
rearward easier when the wheel drive is disengaged.
To disengage the clutches, mower must be pushed
forward at least 2.5 cm (1") after wheel drive operaĆ
tion has stopped.
