BATTERY PACK AND CHARGER
BATTERY CHARGING
1. Use only with 24V LawnMaster
®
battery chargers. The battery charger supplied is specifically designed for
the lithium-ion batteries used in this tool.
2. Check the power voltage! Battery chargers operate on 120V.
3. The batteries are charged between 40°F (4°C) and 100°F (38°C). This ensures an optimum battery
service life.
4. Protect the batteries from heat, from continuous exposure to sun and keep away from radiation or other
heat sources. Do not leave the batteries in the mower in direct sunlight over long periods.
5. The batteries are supplied partially charged. To ensure full capacity of each battery, charge the batteries
before using the tool for the first time. The lithium-ion batteries can be charged at any time without reducing
their service life. Interrupting the charging procedure does not affect the batteries.
LED CHARGER STATUS
1. If batteries are not inserted into the charger, continuous red LED lights indicate that the outlet plug is
plugged into an outlet socket and the battery charger is ready for operation.
2. Charging: Fashing green LEDs on the charger indicate that batteries are charging normally. The LED’s
flashing frequency is 1Hz.
3. Charged: Continuous green LEDs on the charger indicate that batteries are ready for use.
4. Technical Issue: Flashing red LED lights on the charger indicate that batteries have a charging problem
or might be defective.
a) One possible condition is the battery temperature is lower than 32°F (0°C). As soon as the permitted
temperature is reached, the battery charger will automatically switch to charging.
b) If the temperature range is correct and flashing red LED light continues, then remove and reinstall the
battery pack. If the LED status repeats a second time, try to charge another identical battery. If the battery
charges normally, dispose of the defective battery pack (see Environmental Safe Battery Disposal
section).
c) If the flashing red light continues after installing the second battery, the charger may be defective.
Replace with a new one.
5. Flashing green LED lights on the charger (the LED’s flashing frequency (2Hz) is faster than charging
normally (1Hz), which indicates the battery temperature is higher than 122°F (50°C). As soon as the
permitted temperature is reached, the battery charger will automatically switch to charging.
6. After continuous or repeated charging cycles without interruption, the charger may warm up. This is normal
and does not indicate a technical defect of the battery charger.
