SHARPENING THE BLADE
See Figure 14
For best mowing performance, the mower blade must be
kept sharp. A dull blade does not cut grass evenly and
overloads the motor. Under normal circumstances,
sharpening the blade twice during the mowing season is
usually sufficient. However, if your lawn has sandy soil,
more frequent sharpenings may be required.
•
Following the instructions in the
Replacing the
Cutting Blade
section, remove the mower blade.
DO NOT attempt to sharpen the blade while it is
attached to the mower.
•
Using a fine tooth file or stone, sharpen cutting edg-
es on both ends of the blade, removing equal
amounts of material from both ends.
BALANCING THE BLADE
See Figure 15
When sharpening, care should be taken to keep the
blade balanced. An unbalanced blade will cause
excessive vibration when the mower is running. This
vibration will eventually cause damage to the mower,
especially the motor.
WARNING:
When removing, inspect the blade carefully. If blade is
bent or damaged, replace immediately with a new
blade. Failure to replace a bent or damaged blade
could cause an accident resulting in possible serious
injury.
MAINTENANCE
To check blade balance:
•
Clamp a screwdriver horizontally in a vise as
shown.
NOTE:
If a vise is not available, a straight nail can also
be used.
•
Place the center hole of blade on the screwdriver
(or nail) shank.
•
If blade is balanced, it will remain in a horizontal
position. If either end of the blade drops downward,
sharpen the heavy side until the blade is balanced.

BATTERY MAINTENANCE
It is recommended to charge the mower every 3
months for optimum performance when not in use. If
the battery has been in storage for a long time without
recharging, it will be in a low charge state.
