RIDING MOWER
Always observe safety rules when per form ing any
main te nance.
BRAKE OPERATION
If riding mower requires more than four (4) feet to stop at
highest speed in high est gear on a level, dry concrete or
paved surface, then brake must be serviced. (See “TO
ADJUST BRAKE” in the Ser vice and Ad just ments section
of this manual).
TIRES
• Maintain proper air pressure in all tires (See PSI on
tires).
• Keep tires free of gasoline, oil, or insect control chemi cals
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 pre vent flat tires due
to slow leaks, tire sealant may be purchased from your
local parts dealer. Tire sealant also pre vents tire dry rot
and corrosion.

• Front wheel axles and front spindles should be properly
lubricated.
• Wheel Axles should be lubricated with a dry, powdered
graphite type lubricant.
• Spindles should be lubricated with a spray type silicone
