5. Maintenance
Correct and regular cleaning will improve the safe-
ty and extend the lifespan of the device.
For safe and proper working, always keep the
tool and ventilation slots clean.
Τhe tool may be cleaned most effectively with
compressed dry air. Always wear safety goggles
when cleaning tools with compressed air.
Certain cleaning agents and solvents damage
plastic parts. Some of these are: gasoline, carbon
tetrachloride, chlorinated cleaning solvents,
ammonia and household detergents that contain
ammonia.
Store the tool, operating instructions and where
necessary the accessories in the original packag-
ing. In this way you will always have all the informa-
tion and parts ready to hand.
WARNING:
T urn the device off, disconnect it from the mains and wait
until it cools down before cleaning or maintenance to
avoid electric shock or burn.

Install the correct driver bit. Ensure that the Oper -
ating mode selection switch is set to drill mode.
Use the correct speed for the job and apply mini-
mal pressure to the trigger initially. Only increase
the speed when full control can be maintained.
Ke ep sufficient pressure on the drill to prevent the
bit turning out of the screw head. The screw head
can easily become damaged making it difficult to
drive or even remove it.
When attempting to drill a large diameter hole, it is
sometimes best to start with a smaller drill bit
then work up to the required size. This prevents
overloading the drill.
I f the drill bit snugs, switch off immediately to pre-
vent permanent damage to the drill. Try running
the drill in reverse to remove the bit.
K eep the drill in line with the hole. Ideally, the drill
bit should enter at right angles to the work piece.
If the angle is changed during drilling, this could
cause the bit to snap off blocking the hole and
perhaps causing injury.
R educe pressure as the drill is about to break
through the item being drilled. Don’t force the tool,
let it work at its own pace.
For maximum performance, use HSS drill bits for
metal drilling. Set the tool to the drill mode.
Mark off the centre of the hole using a centre
punch.
Use a suitable lubricant for the material you are
working on. 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.
For maximum performance when drilling larger
holes, use auger bits or spade bits for wood
drilling.
Set the tool to the drill mode. Begin drilling at a
very low speed to prevent the bit from slipping off
the starting point. Increase the the speed as it bites
into the wood.
For maximum performance, use high quality
carbide-tipped masonry drill bits when drilling
holes in brick, tile, concrete etc. Use the drilling
setting initially then revert to the hammer action
once the holes are established.
W hen drilling holes in tile, practice on a scrap piece
to determine the best speed and pressure.

Place a block of wood behind the work piece to
prevent ragged or splintered edges on the back of
the hole.
