performing any maintenance on the blades.
ALWAYS remove battery when servicing or
transporting the mower.
NOTE: Only use authorized replacement
blades.
• Stop the motor. Allow blade to come to a
complete stop.
• Remove the battery pack.
• Turn the mower on its side.
• Wedge a block of wood between the blade
and mower deck to prevent the blade from
turning.

turning it counterclockwise (as viewed from
bottom of mower) using a 15 mm wrench
or socket (not provided). For the BLADE II,
loosen the blade nut by turning it clockwise

15 mm wrench or socket (not provided).
• Remove the blade nut, spacer, blade
insulator, and blade.
• Make certain the motor assembly is pushed
completely against the motor shaft.
• Place the new blade on the shaft against
the motor assembly (3). Ensure blade is
properly seated with shaft going through
center blade hole and the two blade posts

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
