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.

the Cutting
Blade for instructions
on
removing
the blade.
_IWARNING!
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.
Failure
to heed this warning
could result in serious personal injury.
_kWARNING!
Before
performing
any
maintenance,
make sure
the mower
is unplugged

could result in serious personal injury.
REPLACING
THE CUTTING
BLADE
See Figures 15 - 16.
NOTE: Only use identical replacement
blades.
• Stop the motor and disconnect
the power supply.
Allow the blade to come to a complete stop.
• Turn the mower on its side.
• Wedge
a block of wood
between
the blade
and
mower deck to prevent the blade from turning.
• Loosen the Made nut using a 15 mm wrench or
socket (net provided).
• Remove the blade nut, spacer, blade insulator, and
blade.
•
Make
certain
the
fan
assembly
is pushed
completely
against the motor shaft.
• Place the new blade
on the shaft against
the fan
assembly.
Make sure it is installed
with the curved
ends pointing
up toward
the mower
deck and not
down toward the ground.
• Replace the blade insulator and spacer, then thread
the blade nut on the shaft and finger tighten.
NOTE:
Make
certain
all parts are replaced
in the
exact order in which they were removed.
• Torque the blade nut down using a torque wrench
(not provided) to ensure the bolt is properly tightened.
The recommended
torque for the blade
nut is 220-
310 in. Ibs.
SHARPENING
THE BLADE
See Figure 17.
For best mowing
performance,
the mower
blade
must be kept sharp. A dull blade does not cut grass
evenly
and overloads
the
motor.
Under
normal
circumstances,
sharpening
the blade twice during the
mowing season is usually sufficient.
However,
if your lawn has sandy soil, more frequent
sharpenings
may be required.
• Following
the instructions
in the Replacing
the
Cutting Blade section, remove the mower blade. DO
NOT attempt to sharpen
the blade while it is attached
to the mower.
_IiWARNING!
When
removing,
inspect
the
blade carefully.
If blade is bent or damaged,
replace
immediately
with
a new blade.
Failure
to replace
a bent or damaged
blade
could cause an accident
resulting
in possible serious injury.
