REPLACING
THE CUTTING
BLADE
See Figures 12 - 13.
Since the mower
is equipped
with a sealed battery,
the mower can be tipped for maintenance
without the
danger of acid spillage.
NOTE: Only use identical replacement
blades.
• Stop the motor and remove the switch key. Allow
blade to come to a complete stop.
• Turn the mower on its side.
• Wedge
a b]ock of wood between
the blade
and
mower deck to prevent the blade from turning.
• Loosen
the blade
nut using a 15 mm wrench
or
socket (not 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 b)ade 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
oil 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 bait is properly tightened.
The recommended

for the blade nut is 220-
310 in. Ibs.
SHARPENING
THE BLADE
See Figure 14.
For best
mowing
performance,
the mower
blade
must be kept sharp. A duff blade does not cut grass
evenly
and overloads
the motor.
Under
normal
circumstances,
sharpening
the blade twice during the
mowing
season is usually sufficienL
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.
