WHERE TO LUBRICATE
Lubricate the areas shown with engine oil.
Apply grease with a brush to the areas shown.
Models with grease fittings: Lubricate with grease gun.
NOTE: Apply grease to the steering gear assembly.
CAUTION: If the unit is operated in dry areas that have sand,
use a dry graphite spray to lubricate the unit.
HOW TO CHECK THE FUEL FILTER
NOTE: Before you replace the fuel filter or the fuel line, the fuel
tank must be empty.
If the fuel filter is dirty, the engine will run rough and have less
performance. Remove the old filter (Figure 21). Replace the old
filter with a new filter. Use an original equipment part. See an
authorized service dealer in your area.

CHECK THE TIRES
Check the air pressure in the tires. Tires 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 14 PSI (1 BAR).
