GENERAL RECOMMENDATIONS
• Always observe safety rules when
performing any maintenance.
• The warranty on this lawn mower does
not cover items that have been
subjected to operator abuse or
negligence. To receive full value from the
warranty, operator must maintain mower
as instructed in this manual.
• Once a year check blade for wear.
• Follow the maintenance schedule in this
manual.
• Before each use check for loose
fasteners.
LUBRICATION
No lubrication is required.
IMPORTANT: Do not oil or grease plastic
wheel bearings. Viscous lubricants will
attract dust and dirt and will shorten the
life of the self-lubricating bearings. If you
feel they must be lubricated, use only a
dry, powdered graphite tube lubricant
sparingly.
TIRES
• 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.

TO BALANCE BLADE
• Check balance of blade by placing
center hole in blade over a nail or
screwdriver shank, clamped horizontally
in a vise. If either end of the blade
rotates downward, file that end. Blade is
properly balanced when neither end
drops.
