Where To Lubricate (Figure 21)
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).
