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.
Torque control
Note: This cordless drill is equipped with a torque control clutch allowing the
machine to be set to the correct torque for the individual application.
• The clutch settings are indicated by the symbols on the Torque Selector (3)
• Rotate the Torque Selector to select the desired setting: the higher the
number displayed on the torque ring, the higher the torque produced by the
tool
Gear selection
• Select gear 1 on the Gear Switch (4) for the higher torque. A lower speed
gear is generally more suitable for driving screws and fasteners
• Select gear 2 on the Gear Switch for the lower torque. A higher speed gear is
for drilling and must not be used for driving screws and fasteners
Note: ALWAYS read the documentation provided with drill bits and accessories
gear. See 'Speciication' for the maximum no load speed of each gear. for the recommended or maximum speed setting and use the most appropriate
Switching on/off
WARNING: ALWAYS wear adequate personal protection equipment when
setting up and operating this machine.
1. To start the drill, squeeze the Trigger Switch (7)
2. The built-in Work Light (9) will illuminate when the Trigger Switch is
squeezed
Note: If the Trigger Switch cannot be pressed down, check that the Forward/
Reverse Switch (6) is not set to its middle position, which locks the device (see
'Direction control').
3. The speed of the drill is controlled by the movement of the trigger: the further
the Trigger Switch is pressed down, the faster the drill will run
4. Release the Trigger Switch to stop the machine
Screwdriver use
Note: Always use a universal bit holder when working with screwdriver bits. Do
not mount screwdriver bits directly into the chuck.
• Select gear 1 using the Gear Switch (4)
• When driving screws NEVER use the machine in drill mode
• Always adjust the drill to the appropriate torque setting (see 'Torque control')

Note: If in doubt which torque setting best suits the application, start with a low
setting and increase, should more torque be required (e.g. if the screw is not
being driven far enough into the workpiece).
Drilling masonry and concrete
• Select hammer drilling mode
• Select the appropriate gear using the Gear Switch (4)
• Hammer drill mode should be used for drilling into masonry and concrete
• Apply moderate pressure to the rear of the drill, in line with the drill bit
• Use masonry drill bits only. Ensure that the bit size is within the maximum
• DO NOT apply too much pressure. If debris blocks the drill hole, run the drill
WARNING: The drill bit, especially the tip, will become very hot when drilling
masonry and concrete. DO NOT touch the bit and never allow it to come into
contact with combustible materials.
WARNING: DO NOT inhale masonry dust. Wear adequate breathing protection.
Dust from masonry, concrete and similar substances is harmful and may be
toxic.
Drilling wood
• Select drilling mode
• Select the appropriate gear using the Gear Switch (4)
• Ensure that drill bits are suitable for wood, and are within the maximum
WARNING: DO NOT inhale wood dust. Wear adequate breathing protection.
Some wood dusts may be toxic.
Drilling metal
• Select drilling mode
• Select the appropriate gear using the Gear Switch (4)
• Ensure that drill bits are suitable for the grade of metal being drilled, and are
• To ensure accuracy, mark the intended hole position using a hammer and
WARNING: The drill bit and the workpiece will become very hot when drilling
metal. DO NOT touch the bit and never allow it to come into contact with combustible materials when hot. Always use a suitable lubricant or cutting luid,
and drill at appropriate speeds.
• ONLY apply moderate pressure to the drill bit, ensuring eficient cutting and
• Use a countersink bit to remove sharp burrs from the hole, preventing cuts
WARNING: If the power tool gets excessively hot in use, stop using the tool
immediately and allow to cool before continuing work. The cooling period can
be reduced by operating the drill at maximum speed with no load. Always make
sure the Motor Vents (5) are not blocked and do not allow dust to enter the body
of the tool through the Motor Vents; dust, especially metallic dust, may damage
or destroy the tool.
