Start slowly
Start driving screws or drilling slowly (i.e. with a low rotational speed, and gradually increase the speed). Press the main switch of your BOSCH Cordless Screwdriver or Impact Drill/Driver only slightly at the start. The more firmly you press the main switch, the faster the machine drives screws or drills. This enables you to start cleanly and prevents the screwdriver bit from slipping out of the screw or the drill bit from slipping away from the marked position.

Hold the machine correctly
Always hold the BOSCH Cordless Screwdriver and Cordless Impact Drill/Driver in a straight position and press it perpendicular to the surface of the wall or of the work piece. BOSCH Cordless Impact Drills/Drivers have an auxiliary handle. You can use this to increase the pressure you apply to the tool and have it better under control. It does not slip away from you so easily.

Drive screws with the right bit
When driving screws, using the wrong bits leads to rapid destruction of the screw head. You should therefore ensure that you have not only the right shape (slotted, cross-head, hexagon socket or Torx) but also the right size.

Use the right screws
Depending on the material and how you attach something, you should ensure that you are using the appropriate screws. The plaster in plasterboard, for example, corrodes non-oxidised screws. For this reason, use black oxidised dry wall screws. The diameter and length of the screws must also be chose carefully: if the screws are too long, they will pass right through the work piece. If they are too thick, they can split thin wood.

Easier drilling in metal
On smooth surfaces such as metal, it is easy for the drill bit to slip slightly and then you drill in the wrong place. To avoid this, first knock a small hole in the metal. Normally you use a punch for this - a steel rod with a surface for hammer blows at one end and a sharp tip at the other. You then place the drill bit in this small hole. In the case of hard material, you can 'pilot drill' with a small diameter drill bit and then complete your drilling with a drill bit of the correct diameter.

Charge the battery correctly
So that the battery pack of your BOSCH Screwdriver has the longest possible service life, it must be treated properly. The greatest danger to a battery pack is from heating during 'overcharging'. To avoid this, BOSCH supplies all cordless screwdrivers and impact drill/drivers with an 'intelligent' quick charger. This detects the remaining charge of the battery pack and stops the current flow as soon as it is fully changed.
