Intended Use

General-purpose cordless power drill for driving screws and for light drilling applications
(excluding masonry).

Unpacking Your Tool

• Carefully unpack and inspect your new sander. Familiarise yourself with all its features
and functions
• Ensure that all parts of the tool are present and in good condition. If any parts are missing
or damaged, have such parts replaced before attempting to use this tool

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 in 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 into the Battery Charger (12)
Note: Make sure the Battery and Battery Charger are lined up correctly. If the Battery does
not slide into 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

Operation

Direction control
WARNING: NEVER change the direction of rotation while the tool is running. This may cause
permanent damage to the tool.
• The direction of rotation can be set using the Forward/Reverse Switch (6)
• For anti-clockwise rotation, push the switch to the right
• For clockwise rotation, push the switch to the left
Note: When the Forward/Reverse Switch is in the central position, the drill is locked and
cannot be switched on. Use this setting as a safety feature to prevent the drill from being
switched on accidentally.
