Charging Advice
IMPORTANT
To obtain the best performance and lengthen the life of the battery pack it should be charged
correctly. DO NOT charge the battery pack in an air temperature below +0ºC (32ºF), or
above +40ºC (104ºF). This is important and will prevent serious damage to the battery pack.
It is normal for the charger and battery pack to become warm to the touch while charging.
The battery pack should be recharged when it fails to produce sufficient power to operate
the tool - (when it loses its “grunt”). DO NOT CONTINUE to use a battery with low voltage or
capacity. Immediately charge the battery.
Always keep the charger battery cavity clear. DO NOT put any metal objects into battery
cavity as it may short circuit the charger.
Always unplug the charger from the power supply or turn off the power supply when there is
no battery pack in the cavity. Unplug the charger before attempting to clean it.
To assist in the cooling of the battery pack after use, avoid placing the charger or battery
pack in a warm environment such as in a metal shed, or an un-insulated vehicle or trailer.
