REPLACING THE CUTTING BLADE

See Fig 9
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 the
mower deck in order to prevent the blade from turning
when the nut is being removed.
■ Loosen the blade nut using a 14 mm wrench or
socket (not provided).
■ Remove the blade nut, and blade.
■ Make certain that the fan assembly does not slide off
of 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.
■ Thread the blade nut on the shaft and fi nger tighten.
NOTE: Make certain all parts are replaced in the exact
order in which they were removed.
■ Torque the blade nut down to 142-159 in. lbs. using a
torque wrench (not provided) to ensure the blade bolt is
properly tightened!

SHARPENING THE BLADE

See Fig 10-A
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 suffi cient. 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.
■ Using a fi ne-tooth fi le or sharpening stone, sharpen
cutting edges on both ends of the blade, removing
equal amounts of material from both ends.
When removing, inspect the blade carefully. If blade
is bent or damaged, replace immediatelywith a new
blade. Failure to replace a bent or damaged blade
could cause an accident resultingin possible serious
injury.
