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 torque 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.
