Battery Pack Operation
Battery Charging
Ensure the batteries are charged between 4°C and 40°C. This ensures an optimum battery service
life.
Protect the batteries from heat, from continuous exposure to sun and keep away from radiation or
other heat sources. Do not leave the battery in the mower in direct sunlight over long periods.
The batteries are supplied partially charged. To ensure full capacity of each battery, charge the
any time without reducing their service life. Interrupting the charging procedure does not affect the
batteries.
Battery LED Indicators
The battery is equipped with a charge-level indicator panel which indicates its charge condition.
This charge-level indicator panel consists of 4 LEDs on the battery. Press and hold the charge
indicator button on the battery to actuate the charge level indicator. The charge level indicator
LEDs go out after releasing the button. The battery charge level can be checked either when the

MAINTENANCE
Balancing the Blade (See Fig. 21)
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.
To check the blade balance:
NOTE: If a vise is not available, a straight nail can also be used.
When removing, inspect the blade carefully. If the 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.

NOTE: Make certain all parts are replaced in the exact order in which they were removed.
Sharpening the Blade (See Fig. 20)
For best mowing performance, the mower blade must be kept sharp. A dull blade does not cut
