WARNING
When servicing, use only identical replacement
parts. Use of any other parts may create a hazard
or cause product damage.
WARNING
Always wear safety goggles or safety glasses with
side shields during power tool operation or when
blowing dust. If operation is dusty, also wear a
dust mask.

GENERAL MAINTENANCE

Avoid using solvents when cleaning plastic parts. Most
plastics are susceptible to damage from various types
of commercial solvents and may be damaged by their
use. Use clean cloths to remove dirt, dust, oil, grease,
etc.
Periodically check all nuts and bolts for proper tightness
to ensure safe operation of the mower.
Remove any buildup of grass and leaves on or around
the engine and engine cover. Wipe the mower clean with
a dry cloth occasionally. Do not use water.

LUBRICATION

All of the bearings in this product are lubricated with a suf-
ficient amount of high grade lubricant for the life of the unit
under normal operating conditions. Therefore, no further
bearing lubrication is required.
WARNING
Always protect hands by wearing heavy gloves
and/or wrapping the cutting edges of the blade
with rags and other material when performing
blade maintenance. Improper handling of blade
could result in serious personal injury.
WARNING
Before performing any maintenance, stop the
mower, allow the blade to come to a complete
stop, and disconnect the spark plug wire from the
spark plug. Failure to follow this warning could
result in serious personal injury.
REPLACING THE CUTTING BLADE
For best results, the mower blade must be kept sharp.
Replace a bent or damaged blade immediately.
WARNING
Only use replacement blades approved by the
manufacturer of your mower. Using a blade not
approved by the manufacturer of your mower
is hazardous and could result in serious injury,
damage your mower, and void your warranty.
