MAINTENANCE
Battery Maintenance
■ Store the battery pack fully charged.
■ Do not allow the battery pack to become completely discharged.
■ Once the battery pack is fully charged, disconnect the charger from the outlet and remove the
battery from the charger.
■ Do not store the battery pack on the tool or on the charger.
■ Charge the battery at a temperature between 4°C and 40°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 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.
Cleaning the Exhaust Port and Muffler
If the blower appears less efficient or powerful, it may be due to the build-up of carbon deposits
around the exhaust port and muffler. This may occur depending on the type of fuel used, the type
and amount of lubricant used, or the operating conditions. In order to restore performance, take
the blower to a qualified service center or qualified individual to remove the blockage.
Cleaning the Air Filter
(See Figs. 25-28)
Keep the air filter clean for proper performance and long life.
■ Rotate the air filter knob counter-clockwise and gently pull off the air filter cover (Fig. 25).
■ Remove the air filter (

) (Fig. 26).
NOTE:
Inspect the filter for damage and replace with a new filter if necessary.
■ Clean the foam filter with warm soapy water and rinse. Air dry the air filter.
■ When the foam filter is completely dried, moisten it with a teaspoon of 2-stroke engine oil.
■ Place the air filter back, ensuring that it is properly seated onto the base. Installing the filter
correctly will decrease the chances of engine wear caused by dirt entering the engine (Fig. 27).
