For metal, use only flawless, sharpened drills; for stone
and concrete, only masonry drills with hard metal inserts.
Always adapt the speed to the material to be worked and
the diameter of the drill. For precision working with metal
and wood, place the machine in a drill stand (accessory).
HAMMER-DRILLING
Wear protective glasses and hearing
protection. Do not apply too much pressure.
The performance is not increased in this manner.
For hammer drilling, work only with protective glasses,
hearing protection and the auxiliary handle. Check before
putting into operation if the shift knob is latched in the
position.
DRILLING IN TILES
Start drilling slowly on the tile. After the tile is drilled
through, switch to hammer drilling.

Screwdriver bits can be inserted into the adapter (see
accessory). Commercially available bits with a hexagonal
dimension of 6.35mm (1/4") can be used.
The screwdriver bits are held in the adapter with a
spring ring. Use only bits with a notch.

releases.
Remove the load from the machine immediately by
pulling back the drilling tool.
Always hold the machine tightly with both hands and
assume a secure stance.
