RiDiNG MOWER

any maintenance.
BRAKE OPERATION
If riding mower requires more than four (4)
feet to stop at highest speed in highest gear
on a level, dry concrete or paved surface,
then brake must be serviced at your nearest
authorized service center.
TIRES
• Maintain tire pressure at 12 PSI.
Keep tires free of gasoline, oil, or insect
control chemicals which can harm rubber.
Avoid stumps, stones, deep ruts, sharp
objects and other hazards that may cause
tire damage.
NOTE: To seal tire punctures and prevent
flat tires due to slow leaks, tire sealant may
be purchased from your local parts dealer.
Tire sealant also prevents tire dry rot and
corrosion.

be properly lubricated.
Wheel axles and spindles should be
lubricated with grease.
