MAINTENANCE
WARNING
Always protect hands by wearing heavy gloves and/or wrapping the cutting edges of the blade with rags
and other material when performing blade maintenance. Failure to heed this warning could result in
serious personal injury.
WARNING
Before performing any maintenance, make sure the mower is switched off and the safety key and
batteries have been removed. Failure to heed this warning could result in serious personal injury.
REPLACING THE MOWER BLADE
NOTE: Remove safety key and batteries before performing any maintenance!
1. Stop the motor and allow the blade to come to a complete stop.
2. With the blade stopped, remove the SAFETY KEY and the BATTERIES from the mower and store
in safe location.
3. Slowly turn the mower onto its side.
4. Wedge a block of wood between the blade and the mower deck in order to prevent blade from
turning while the blade nut is being removed (Fig. 13).
5. Loosen the blade nut using a wrench or socket (not provided).
6. Remove the blade nut by turning counter-clockwise, and then remove the blade.
7. Place the new blade on the shaft. Make sure it is installed with the curved ends pointing up toward
the mower deck and not down toward the ground.
8. Thread the blade nut on the shaft and finger tighten.
9. Torque the blade nut down using a torque wrench (not provided) to ensure the bolt is properly
tightened (Fig. 14).
NOTE: Make certain all parts are replaced in the exact order in which they were removed.
