Before Use

Removing a battery
• To remove the Battery (10) from the drill, press the Battery Release (11) on
both sides of the tool, then pull the Battery out of the Hand Grip (8)
WARNING: DO NOT try to remove the Battery without pressing the Battery
Release button. The drill or Battery could be damaged.
Fitting a battery
1. To fit a charged battery, slide it on to the Hand Grip (8) of the drill until it
clicks and locks into position
Note: Make sure the Battery and drill are lined up correctly. If the Battery does
not slide into the drill easily, don't force it. Instead, slide the Battery out of the
drill again, check the top of Battery and the drill 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 (12)
2. Insert the Mains Plug (13) into a suitable mains socket
Note: The Green LED (14) on the Battery Charger will illuminate to indicate that
the charger is ready to charge the battery.
WARNING: ONLY use this charger 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 1 hour for a recently discharged battery.
However, if the Battery (8) has been left in a discharged state for some time, it
may take up to 1.5 hours to charge.
1. Slide a fully or partially discharged Battery on to the Battery Charger (12)
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 will illuminate
3. When the Battery is fully charged only the Green LED will be illuminated
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
• Batteries can become faulty over time, individual cells in the battery can fail
and the battery could short. The charger will not charge faulty batteries. Use
another battery, if possible, to check correct functionality of the charger and
purchase a replacement battery if a faulty battery is indicated
• DO NOT store Lithium-Ion battery packs in a discharged state long term.
This can damage the Lithium-Ion cells. For long-term storage, store batteries
in a high charge state disconnected from the power tool
• The capacity of batteries will reduce over time. After 100 charge cycles, the
battery's operation time and the maximum torque performance of the drill
will slightly reduce. This decline will continue until the battery has minimal
capacity after 500 charge cycles. This is normal and not a fault with the
battery pack
Fitting drill bits and accessories
WARNING: ALWAYS remove the Battery from the drill before attaching,
adjusting or removing accessories.
WARNING: DO NOT attempt to tighten drill bits (or any other accessory) by
gripping the front part of the chuck and switching the tool on. This can lead to
personal injury and can cause damage to the chuck.
WARNING: NEVER fit any accessory or bit with a maximum speed lower than
the no load speed of the power tool.
1. Open the Chuck Jaws (1) by holding the rear of the Chuck Collar (2) and
rotating the front of the Chuck Collar anti-clockwise
2. Place the drill bit or accessory centrally into the chuck
3. Tighten the Chuck Jaws by rotating the front of the Chuck Collar clockwise
while holding the rear of the Chuck Collar
4. When the drill bit or accessory is securely fastened, carefully run the
machine to test that it is running centrally, smoothly and evenly. If the bit is
'wobbling' or not running centrally, release the chuck, check the accessory
for damage, correct its position, retighten and test again
