Preparing the tool for use / Cleaning and Maintenance
Note: The integrated motor brake ensures the
shaft quickly stops rotating - so that you can get to
work again fast.
Q Switching direction of rotation
j
To switch the direction of rotation, push the
direction of rotation switch 3 to either the
right or to the left.
Q Tips and Tricks
When screwing into wood, metal and
other materials, take note of the following
advice:
j
Before you use the appliance, check to see
that the screw or drill bit is properly fitted, i.e.
located centrally in the chuck.
j Screw bits are designated with their dimensions
and their shape. If you are unsure, always try
the particular screw bit out to see whether it sits
in the screw head without any free play.
Torque:
j Smaller screws and bits in particular can be
easily damaged if you adjust the appliance
with too high a torque and/or rotation speed.
Hard screw bed:
j Particularly high torques can occur, for example
with metal screws tightened by socket tool bits.
Select a lower rotation speed.
Soft screw bed:
j You should also select a low speed in order not
to damage the wood workpiece surface through
contact with the metal screw head. Use a coun-
tersinker.
When drilling into wood, metal and other
materials, take note of the following advice:
j
With small diameter drill bits use a high drill
speed. for large diameter drill bits, use a low
drill speed.
j for hard materials, select a low drill speed.
for soft materials, select a high drill speed.
j Secure or fix down the workpiece (if possible)
in a clamp or vice.
j Mark the intended position of the hole with a
centre punch or a nail and select a low drill speed
for drilling.
j Take the rotating drill bit out of the hole frequently
so that swarf or drill dust can be re-moved and
the hole and tool is ventilated.
Drilling in metal:
j
Use a metal drill bit (HSS). for the best results,
you should cool the bit with oil. Metal drill bits
can also be used to drill into plastic.
Drilling in wood:
j
normally you should use a wood drill with a
centring point. for deep holes, use an auger
type bit. for large diameter holes, use a forst-
ner bit. You can screw small screws into soft
wood without the need for pre-drilling.
Q Cleaning and Maintenance
m CAUTION! Place the direction of rotation
switch 3 into the middle position before carrying
out any tasks on the device, e.g. changing tools or
maintenance, or before transporting or storing the
device. Inadvertent operation of the On / Off
switch
4 may result in injury.
Always pull the mains adapter 10 out of the mains
socket and remove the battery pack before you
clean or maintain the device.
The Cordless Drill / Screwdriver is maintenance-free.
j Always keep the device clean, dry and free of
oil or grease.
j
Clean the device immediately after you have
finished using it.
j
Do not allow any liquids to enter the device.
Use a cloth to clean the housing.
j
never use petrol, solvents or cleaning agents
that might attack plastic.
