Inserting and removing bits
The drill is fitted with auto spindle lock which means if you
try and rotate the chuck by hand the spindle of the drill
will automatically lock. This means you only need to grasp
the chuck and rotate the chuck housing to remove or fit
accessories.
This drill has a keyless chuck, hence a chuck key is not
needed to secure a bit in the drill. Always set the forward/
reverse switch (4) to the locked ‘OFF’ position when
installing and removing bits. It is also recommended to
remove the battery pack to avoid unintentional starting.
1. Open the chuck jaws by firmly holding the chuck
housing and rotating the
housing in an anti-clockwise
direction. Open the jaws
sufficiently so as to fit the
desired accessory.
2. Ensure the accessory is fully
inserted, so that the jaws of
the chuck grip onto the flat
section of the accessory.
3. To firmly clamp the accessory in the chuck, grasp
the chuck housing and rotate the chuck housing in a
clockwise direction. Ensure the bit is retained firmly or
damage to the chuck jaws can result.
4. To remove the accessory, open the chuck jaws by firmly
holding the chuck housing and rotating the housing in
an anti clockwise direction. Open the jaws sufficiently so
as to remove the specific accessory.
Adjustable side handle
1. Turn the side handle clamp
knob (6) anti-clockwise
to loosen the collar fully and
slip it over the chuck (1) onto
the drill.
2. Adjust the position of the side
handle (5) to suit the
application and tighten the side handle clamp knob (6)
to secure it in place.
Drilling
Drilling metals
•
For maximum performance, use high speed steel bits for
metal or steel drilling.
•
Ensure that the torque adjustment / hammer selection
collar (2) is in normal drilling mode.
•
Begin drilling at a very low speed to prevent the bit from
slipping off the starting point.
•
Always clamp sheet metal.
•
Support thin metal with a block of wood to avoid
distorting it.
•
Use a punch to mark the centre of the hole.
•
Use a suitable lubricant for the material you are working on.
Use:
for:
Oil
Steel
Turpentine or paraffin
Aluminium
Do not lubricate
Brass, copper or cast iron
Drilling plastics and plastic coated chipboard
•
Use high speed drill bits
•
See drilling wood below
Drilling masonry
•
For maximum performance use carbide-tipped masonry
impact bits when drilling holes in brick, tile, concrete etc.
•
Turn the mode selector to hammer mode, then rotate the
torque collar to the drill position.
•
Apply light pressure and medium speed for best results
in brick.
•
Apply additional pressure and high speed for hard
materials such as concrete.
•
When drilling holes in tile, practice on a scrap piece to
determine the best speed and pressure.
