MAINTENANCE
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.
WARNING:
Do not at any time let brake fluids, gasoline, petroleum-
based products, penetrating oils, etc., come in contact
with plastic parts. Chemicals can damage, weaken, or
destroy plastic which may result in serious personal
injury.
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
motor cover. Wipe the mower clean with a dry cloth occa-
sionally.
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.
At the beginning and end of each mowing season:
 Lubricate the springs on the rear discharge door with light
oil.
 Lubricate the height adjustment lever and related hardware
with light oil.
 Remove the wheels and lubricate the surface of the axle
bolt and the inner surface of the wheel with light oil.
 Remove the blade and blade hub assembly and lubricate
the motor shaft with light oil or engine oil. See Replac-
ing the Cutting Blade for instructions on removing the
blade.
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. Fail-
ure to heed this warning could result in serious personal
injury.
WARNING:
Before performing any maintenance, make sure the
mower is unplugged from the power supply. Failure
to heed this warning could result in serious personal
injury.
