MAINTENANCE
REPLACING THE CUTTING BLADE
See Figures 18 - 19.
NOTE: Only use authorized replacement blades.

Stop the motor and remove the start key. Allow the blade
to come to a complete stop.

Remove the battery pack from the battery port.

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 blade nut by turning it counterclockwise (as
viewed from bottom of mower) using a 15 mm wrench
or socket (not provided).

Remove the blade nut, spacer, blade insulator, and blade.
Do not remove the hub or the adaptor.
WARNING:
If the hub and/or the adaptor have been removed, replace
them before placing blade on the shaft. Failure to do so
could cause the blade to detach or become unbalanced
since blade will not tighten properly, which can result in
serious personal injury.

Place the new blade on the shaft against the blade posts
on the hub. Ensure blade is properly seated with shaft go-
ing through center blade hole and the two blade posts on
the hub inserted into their respective holes on the blade.
Make sure it is installed with the curved ends pointing up
toward the mower deck and not down toward the ground.
When seated properly, the blade should be flat.

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 clockwise using a torque
wrench (not provided) to ensure the bolt is properly
tightened. The recommended torque for the blade nut is
310 – 360 in.lbs.
WARNING:
Ensure blade is properly seated and the blade nut is
tightened to the torque specifications above. Failure to
properly attach the blade could cause it to come loose
and result in possible serious personal injury.
STORING THE MOWER

tery storage compartment and start key and store in a

ous personal injury.
