Use
Fit a suitable drill or bit for the task. Select
gear, direction and torque.
Start the drill by pressing the on/off button
(8). The longer the button is depressed, the
faster the chuck will revolve. The LED work
light (10) comes on and lights up the working
area when you press the on/off button.
Allow the drill to reach full speed before
starting to drill.
Do not press the drill too hard. Select a low
speed for screwing, large drill bits or hard
materials and a higher speed for small drill
bits or softer materials.
Switch off by releasing the on/off button.
Useful tips for drilling
When drilling in smooth surfaces, e.g. tiles,
stick a piece of strong tape on the drilling
point before drilling to prevent the bit
slipping. Always centre-punch the drilling
point � rst when drilling steel.
Place a piece of scrap wood under the item
when drilling thin sheet metal to avoid
deforming the sheet. Lubricate the drilling
point with oil when drilling into metal. Use
machine oil for steel and paraffi n oil for
aluminium.
To avoid splinters when drilling wood or
plastic, place a piece of scrap wood under
the item or drill from both sides.
Use a high speed drill bit when drilling
plastic.
For large diameter holes, start with a small
diameter drill and then use the desired
diameter.

Cleaning and maintenance

Clean the drill with a slightly damp cloth or
compressed air after use and always keep all
surfaces and ventilation slots free from dust.
Never use corrosive or abrasive cleaning
agents, as they may attack the plastic parts
of the drill.
