Loosening the Drill Chuck

(see figure )

Place the machine on a stable surface (e. g.

workbench). Hold the machine firmly and loosen

the chuck by turning to the left, as when unscrew-

ing a screw (

➊). Loosen a tight chuck by giving

the long end of the Allen key 16 a sharp blow.

Tightening the Drill Chuck

(see figure )

The drill chuck is mounted in reverse order (

➋

The chuck must be tightened with a torque of

approx. 35–40 Nm.

Speed as well as torque setting depend on the

material and can be determined by practical test-

ing. Always start with the lowest setting.

After longer periods of working at low speed, al-

low the machine to cool down by running for ap-

prox. 3 minutes at maximum speed with no load.

For drilling in tiles, set the selector switch 2 to the

symbol “Drilling and Screwdriving”. Do not switch

over to the symbol “Impact Drilling” or work with

impact until after drilling through the tile.

Carbide tipped drill bits are required for jobs

when working in concrete, masonry and brick

wall.

■ Before any work on the machine itself, pull the

mains plug.

■ For safe and proper working, always keep the

machine and the ventilation slots clean.

If the machine should fail despite the care taken

in manufacturing and testing procedures, repair

should be carried out by an after-sales service

centre for Bosch power tools.

In all correspondence and spare parts orders,

please always include the 10-digit order number

given on the nameplate of the machine.
