the unit, disconnect the wire to the
spark plug. Remove the spark plug wire to
prevent the engine from starting by acci-
dent
1. Make sure the unit is on a hard flat surface.
2. Check the air pressure in the tyres. If the air
pressure is incorrect, the mower housing will
not cut level. Make sure the tyres are inflated
to: Front Tyres 0,97 BAR (14 PSI), Rear
Tyres 0,69 BAR (10 PSI).
3. (Figure 13) Move the lift lever (1) to the
lowest cut position (2).
WARNING: The lifter lever (3) is
spring loaded. Make sure the lift
lever (3) is locked in the lowest cut
position (2).
4. (Figure 14) Loosen the left and right ad-
juster knobs (1). Push down on each side of
the mower housing. Make sure both sides of
the mower housing are setting on a flat sur-
face. Also, make sure the lift links are loose
and can easily move up or down.
5. Push down on the lift links (2) and tighten
the left and right adjuster knobs (1). Make
sure the adjuster knobs (1) are tight. If
necessary, use a wrench to tighten the ad-
juster knobs (1).
6. (Figure 13) Raise the lift lever (1).
7. Mow for a short distance. If the height of cut
is not level, repeat the above steps.
Where To Lubricate (Figure 15)
Models with grease fittings:
Lubricate with grease gun.
Apply grease with a brush to
the areas shown.
Lubricate the areas shown
with engine oil.
NOTE: Apply grease to the steering gear as-
sembly.
CAUTION: If the unit is operated in dry areas
that have sand, use a dry graphite spray to
lubricate the unit.
Check The Tyres
Check the air pressure in the tyres. Tyres with
too much air pressure will cause the unit to ride
rough. Also, the wrong air pressure will keep the
mower housing from cutting level. The correct
air pressure is: Front Tyres 0,97 BAR (14 PSI),
Rear Tyres 0,69 BAR (10 PSI).
