location. If the drill-hole is deep, the drill-bit may become jammed in the hole. In this event a high torque could
damage the drill bit or the drill. If the bit becomes jammed, hold the machine firmly and immediately release the
On/Off trigger. Switch to anticlockwise rotation, and use a low rotation speed to remove the jammed drill bit
more easily.
4. Drilling in Plastic
For drilling in plastic use a steel drill and follow the same instructions as for drilling in wood.
5. Drilling in Stone, Brick, Masonry or similar
For drilling in walls, stone, masonry etc. use a masonry-bit. Do not put too much pressure on the machine.
Follow the same instructions as for drilling in metal.
6. Using the Drill as a Screw-driver
Before using the machine check whether the screw-bit is inserted correctly. Avoid over-tightening screws,
otherwise the screw head may be damaged or stripping of the threads may occur.
7. Screw Insertion
Set the direction of rotation of the drill to the clockwise direction. Insert the screw-bit into the slot in the head of
the screw. Hold the screw bit perpendicular to the head of the screw, otherwise the screw or the screw head
may be damaged. Press the screw bit against the screw with a constant pressure while driving in the screw.
When the screw is completely screwed in, hold the machine firmly and release the forward & reverse switch,
otherwise the screw or the screw head may be damaged. If the forward & reverse switch is not released
immediately a high torque could also damage the drill bit or the drill.
8. Screw Removal
Set the direction of rotation of the drill to the anticlockwise direction. Insert the screw-bit into the slot in the head
of the screw. Hold the screw-bit perpendicular to the head of the screw, otherwise the screw or the screw head
may be damaged. Press the screw bit against the screw with a constant pressure while removing the screw.
Maintenance and Clean
Attention! Always remove the battery before carrying out any work on the machine.
To clean, always use a dry or moist, but not wet, towel. Many cleaning agents contain chemical substances
which may cause damage to the plastic parts of the machine. Therefore do not use any strong or inflammable
cleaners such as petrol, paint thinner, turpentine or similar cleaning agents.
Always keep air ventilation holes free of dust deposits to prevent overheating.
