ENGLISH
Use percussion carbide tipped masonry drill-bits.
When drilling a hard, smooth surface (e.g. tiles), cover the point to be drilled with
adhesive tape in order to prevent the drill tip from skidding.
Center punch the point you have marked for drilling.
Always hold sheet metal firmly in a vice.
Lay a block of wood under thin metal to prevent it from distorting.
Use HSS spiral drill bits. (For white cast iron, use drill bits with special tips.)
Before drilling large-diameter holes, first drill a small pilot hole.
Use lubricant:
Steel: Oil
Aluminium: Turpentine, paraffin
Brass, copper, cast iron: no lubricant, but take the drill out of the hole frequently to
cool it off.
Center punch the point you have marked for drilling. To prevent the wood from
splintering when the drill bit tip breaks through, lay a piece of scrap wood underneath
it, or drill from both sides.The maximum drill-diameter can only be reached with a
Forstner–drill bit.
Use screwdriver bits of the appropriate size and shape.
Suitable screws can be driven into softwood without pre-drilling.
Pre-drill into hardwood or for screws of large diameter.
Pre-drill further for countersunk screws.
For woodscrews threaded less than their full length, pre-drill approx. half the length
of the screw.
The ventilation slots of the machine must be kept clear at all times.
Always disconnect the plug from the
socket before carrying out any work on the
machine.

If the machine is mainly used for percussion drilling, regularly remove collected
dust from the chuck. To remove the dust hold the machine with the chuck facing
down vertically, and completely open and close the chuck. The collected dust will
fall from the chuck.
It is recommended to regularly use cleaner for the clamping jaws and the clamping
jaw borings.
