Battery Charger Safety

Use the battery charger correctly
• Refer to the section of this manual relating to use of the battery charger before attempting to charge
the battery.
• Do not attempt to use the charger with any batteries other than those supplied. Keep your battery charger
clean; foreign objects or dirt may cause a short or block air vents. Failure to follow these instructions may
cause overheating or fire
• If the supply cord is damaged, it must be replaced by the manufacturer, its service agent or similarly
qualified persons in order to avoid a hazard
• Examine the battery charger regularly for damage, especially the cord, plug and enclosure. If the battery
charger is damaged, it must not be used until it has been repaired
• Children should be supervised to ensure that they do not play with the appliance
WARNING: DO NOT attempt to recharge non-rechargeable batteries.
Battery and charger safety features
The battery and charger are fitted with a number of safety features which may be triggered during charging
or operation:
• Over-charge protection: Charger automatically switches off when the battery has reached full charge
capacity, protecting the internal components of the battery
• Over-discharge protection: Prevents the battery from discharging beyond the recommended lowest
safety voltage
• Over-heat protection: Sensor switches off if the battery becomes too hot during operation. This can
happen if the tool is overloaded or being used for extended periods of time. Up to 30 minutes cooling time
may be required depending on the ambient temperature
• Overload protection: Battery temporarily stops if it is overloaded or the maximum current draw is
exceeded, protecting the internal components. The battery will resume normal operation when the current
draw returns to a normal safe level. This may take a few seconds
• Short circuit protection: The battery will stop working immediately if a short circuit occurs, this prevents
damage to the battery or tool

Before Use

Removing a battery
• To remove the Battery (11) from the tool, press the Battery Release (12), then slide the Battery out of the
Battery Slot (10)
WARNING: DO NOT try to remove the Battery without pressing the Battery Release button. The tool or Battery
could be damaged.
Fitting a battery
1. To fit a charged battery, slide it on to the Battery Slot (10) of the tool until it clicks and locks into position
Note: Make sure the Battery and tool are lined up correctly. If the Battery does not slide into the tool easily,
don't force it. Instead, slide the Battery out of the tool again, check the top of Battery and the tool battery slot
are clean and undamaged and that the contacts are not bent.
Setting up the battery charger
1. If fitted, remove any Battery from the Battery Charger (18)
2. Insert the Battery Charger mains plug into a suitable mains socket
Note: The Green LED (19) on the Battery Charger will flash to indicate that the charger is ready to charge
the battery.
WARNING: Use this charger ONLY to charge the supplied battery or additional purchased batteries that are
specifically designed for this tool.
WARNING: The charger is designed for indoor use only, and MUST NOT be used in damp or wet conditions.

Charging the battery

WARNING: Failure to follow the correct procedure when charging batteries will result in permanent damage.
Note: Normal charging time is approximately 1 hour for a recently discharged 3.0Ah capacity battery.
However, if the Battery (11) has been left in a discharged state for some time, it may take additional time to
charge.
1. Slide a fully or partially discharged Battery on to the Battery Charger (18)
Note: Make sure the Battery and Battery Charger are lined up correctly. If the Battery does not slide on to the
Battery Charger easily, don't force it. Instead, remove the Battery, check the top of Battery and the Battery
Charger slot are clean and undamaged and that the contacts are not bent.
2. Once charging commences, the Red LED (17) will illuminate
3. When the Battery is fully charged, the Green LED (19) will illuminate
Battery Charge Level: The Battery has a built-in Battery Charge Indicator (9) (Fig. I). Pressing on the button
to the right will indicate the charge level. The right LED indicates a high charge level and the left a low charge
level that will mean the battery pack will require charging soon.
IMPORTANT: When a low charge level is indicated, the tool may stop operating while in use. In some
instances this may be dangerous. Always ensure the battery pack has a good charge level.
Notes about battery charging:
• The battery should be charged at ambient temperatures between 10 and 40°C (ideally around 20°C)
• After charging, allow 15 minutes for the battery to cool before use
• Ensure that the charger is disconnected from the mains supply after use, and is stored correctly
• DO NOT leave batteries on charge for extended periods and NEVER store batteries on charge
• The Battery Charger monitors battery temperature and voltage while charging. Remove the Battery once
charging has been completed to maximise charge cycles of the battery and not waste power
