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. • For the BLADE I, loosen the blade nut by 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 (as viewed from bottom of mower) using a 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 (4) 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 against the motor assembly. Install the blade insulator (5) and spacer (6), then thread the blade nut (7) on the shaft and finger tighten. 1 3 4 2 1 5 5 6 6 7 7 NOTE: Make certain all parts are replaced in the exact order in which they were removed. • For the BLADE I, torque the blade nut down clockwise using a torque wrench (not provided) to ensure the bolt is properly tightened.
