Practical Advice
Pull the plug out of the socket before carrying out any
u
work on the power tool.
Only apply the power tool to the screw/nut when the
u
tool is switched off. Rotating tool inserts can slip off.
After working at a low speed for an extended period, you
should operate the power tool at the maximum speed for ap-
proximately three minutes without load to cool it down.
To drill into tiles, set the selector switch (2) to the "drilling"
symbol. After drilling through the tile, set the selector switch
to the "impact drilling" symbol and drill with impact.
Use carbide drill bits when working with concrete, stone and
masonry.
When drilling into metal, only use sharpened HSS drills (HSS
= high-speed steel) which are in perfect condition. The
Bosch accessory range guarantees appropriate quality.
Using the drill bit sharpener (accessory), you can effortlessly
sharpen twist drill bits with a diameter of 2.5–10 mm.
