BATTERY MAINTENANCE
■ Store the battery pack fully charged.
■ Charge the battery pack whenever there is a noticeable reduction in the trimming performance.
Do not allow the battery pack to become completely discharged.
■ Once the battery pack is fully charged, remove the battery from the charger and disconnect the
charger from the outlet.
■ Do not store the battery pack on the tool or on the charger.
■ Charge the battery at a temperature between 40°F (4°C) and 100°F (38°C). If the battery pack
is hot, allow it to cool down before charging.
Storing the battery for 30 days or longer:
If the lithium-ion battery is being stored for 30 days or longer, store the battery pack in a location
where the temperature does not exceed 80°F (26°C) and is free of moisture.
- Store the battery pack in a 30%-50% charged condition.
- Fully charge the battery back every six months.
- The exterior part of the battery pack may be cleaned with a cloth or soft non-metallic brush.
CHARGER MAINTENANCE
■ Keep the charger clean and clear of debris. Do not allow foreign material into the recessed
cavity or on the contacts. Wipe with a dry cloth. Do not use solvents, water, or place in wet
conditions.
■ Always unplug the charger when the battery pack is not installed on the charger.
■ Keep the charger stored at normal room temperature. Do not store it in excessive heat. Do not
use in direct sunlight.
■ Disconnect the charger from the AC power outlet when not in use and once the battery has
reached a full charge.
SPOOL REPLACEMENT

■ Hold the trimmer head cover. Using the index finger and thumb firmly squeeze the locking tabs
on the trimmer head housing. Then remove the trimmer head cover (Fig. 22).
