WARNING:
Before performing any maintenance, make sure the mow-
er battery and fuse key are removed to avoid accidental
starting and possible serious personal injury.
WARNING:
When servicing, use only authorized replacement parts.
Use of any other parts may create a hazard or cause
product damage.
WARNING:
Always wear eye protection with side shields marked to
comply with ANSI Z87.1. Failure to do so could result in
objects being thrown into your eyes resulting in possible
serious injury.
GENERAL MAINTENANCE
Avoid using solvents when cleaning plastic parts. Most
plastics are susceptible to damage from various types of
commercial solvents and may be damaged by their use. Use
clean cloths to remove dirt, dust, oil, grease, etc.
WARNING:
Do not at any time let brake fluids, gasoline, petroleum-
based products, penetrating oils, etc., come in contact
with plastic parts. Chemicals can damage, weaken, or
destroy plastic which may result in serious personal
injury.
Periodically check all nuts and bolts for proper tightness to
ensure safe operation of the mower.
Remove any buildup of grass and leaves on or around the
motor cover. Wipe the mower clean with a dry cloth occa-
sionally. Do not use water.
LUBRICATION
All of the bearings in this product are lubricated with a suf-
ficient amount of high grade lubricant for the life of the unit
under normal operating conditions. Therefore, no further
bearing lubrication is required.
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.
Contact with the blade could result in serious personal
injury.
REPLACING THE CUTTING BLADE
See Figure 14 - 15.
NOTE: Only use authorized replacement blades.

Stop the motor and remove the fuse key. 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.
 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.
 Make certain the fan assembly is pushed completely
against the motor shaft.
 Place the new blade on the shaft against the fan as-
sembly. Ensure blade is properly seated with shaft go-
ing through center blade hole and the two blade posts
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 fan
assembly.
 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 tight-
ened. The recommended torque for the blade nut is 350-
400 in. lbs.
