Bosch Power Tools 2 609 140 654 | (21.7.11)

Assembly

f Before any work on the machine itself, pull the mains

plug.

Changing the Tool

f Wear protective gloves when changing the tool. The

drill chuck can become very hot during longer work peri-

ods.

Keyless Chuck (see figure A)

Hold the rear sleeve 3 of the keyless chuck 1 tight and turn the

front sleeve 2 in rotation direction n, until the tool can be in-

serted. Insert the tool.

Hold the rear sleeve 3 of the keyless chuck 1 tight and firmly

tighten the front sleeve 2 by hand in rotation direction o, un-

til the locking action (click) is heard. The drill chuck is locked

automatically.

The locking is released again to remove the tool when the

front sleeve 2 is turned in the opposite direction.

Screwdriver Tools (see figure B)

When working with screwdriver bits 9, a universal bit holder

10 should always be used. Use only screwdriver bits that fit

the screw head.

Replacing the Drill Chuck

For machines without spindle lock, the drill chuck must be re-

placed through an authorized after-sales service agent for

Bosch power tools.

The drill chuck must be tightened with a tightening

torque of approx. 31–35 Nm.

Dust/Chip Extraction

f Dusts from materials such as lead-containing coatings,

some wood types, minerals and metal can be harmful to

one’s health. Touching or breathing-in the dusts can cause

allergic reactions and/or lead to respiratory infections of

the user or bystanders.

Certain dusts, such as oak or beech dust, are considered

as carcinogenic, especially in connection with wood-treat-

ment additives (chromate, wood preservative). Materials

containing asbestos may only be worked by specialists.

– Provide for good ventilation of the working place.

– It is recommended to wear a P2 filter-class respirator.

Observe the relevant regulations in your country for the

materials to be worked.

f Prevent dust accumulation at the workplace. Dusts can

easily ignite.

Operation

Starting Operation

f Observe correct mains voltage! The voltage of the pow-

er source must agree with the voltage specified on the

nameplate of the machine. Power tools marked with

230 V can also be operated with 220 V.

Reversing the Rotational Direction (see figure C)

The rotational direction switch 7 is used to reverse the rota-

tional direction of the machine. However, this is not possible

with the On/Off switch 6 actuated.

Right Rotation: For drilling and driving in screws, push the

rotational direction switch 7 left to the stop.

Left Rotation: For loosening and unscrewing screws and

nuts, press the rotational direction switch 7 through to the

right stop.

Switching On and Off

To start the machine, press the On/Off switch 6 and keep it

pressed.

To lock the pressed On/Off switch 6, press the lock-on button

To switch off the machine, release the On/Off switch 6 or

when it is locked with the lock-on button 5, briefly press the

On/Off switch 6 and then release it.

Adjusting the Speed

The speed of the switched on power tool can be variably ad-

justed, depending on how far the On/Off switch 6 is pressed.

Light pressure on the On/Off switch 6 results in a low rotation-

al speed. Further pressure on the switch results in an increase

in speed.

Working Advice

f Apply the power tool to the screw/nut only when it is

switched off. Rotating tool inserts can slip off.

For drilling in metal, use only perfectly sharpened HSS drill

bits (HSS=high-speed steel). The appropriate quality is guar-

anteed by the Bosch accessories program.

Twist drills from 2.5–10 mm can easily be sharpened with

the drill bit sharpener (see accessories).

Belt Clip

With the belt clip 4, the machine can be hung onto a belt. The

user has both hands free and the machine is always at hand.

Maintenance and Service

Maintenance and Cleaning

f Before any work on the machine itself, pull the mains

plug.

f For safe and proper working, always keep the machine

and ventilation slots clean.

If the replacement of the supply cord is necessary, this has to

be done by Bosch or an authorized Bosch service agent in or-

der to avoid a safety hazard.

If the machine should fail despite the care taken in manufac-

turing and testing procedures, repair should be carried out by

an after-sales service centre for Bosch power tools.

In all correspondence and spare parts order, please always in-

clude the 10-digit article number given on the type plate of

the machine.
