Inserting the Tool

Open the drill chuck sufficiently for the tool to be in-

serted. Insert the tool. Turn the sleeve of the quick-

clamping drill chuck 3 forcefully by hand until a distinct

"click" is heard. The drill chuck is thereby automatically

locked.

Turn the chuck casing in the reverse direction to remove

the tool.

Clamp the screwdriver bit 12 directly in the drill chuck or

use an additional universal bit holder for screwdriver bits

(accessory magazine 13 ).

Initial Operation

Inserting the Battery

Set the rotational direction switch 5 to the cen-

tre = locked position, and notch the charged battery 7

into the grip.

Switching On and Off

Press the On/Off switch 4 and then let go again.

Run-On Brake

As soon as the On/Off switch 4 is let go, the speed of the

drill chuck is immediately slowed down together with the

inserted tool.

Stepless Speed Control

The machine runs with variable speed be-

tween 0 and maximum depending on the

pressure applied to the On/Off switch 4 .

Changing the Rotational Directions

The rotational direction switch 5 serves for alternating

the directional rotation of the machine. However, this is

not possible if the On/Off switch 4 is being pressed.

Speed Selector, Mechanical

Two speed ranges can be preselected with the gear se-

lector 1 :

1st gear:

Low rotational speed, high power.

2nd gear:

High rotational speed, low power.

The speed settings may only be changed when the ma-

chine is motionless. If the speed setting has not quite

notched in properly, briefly press the On/Off switch 4 .

For drilling and inserting

screws, set the rotational di-

rection CLOCKWISE

For unscrewing, switch to the

rotational

direction

ANTICLOCKWISE

Setting the Torque

In order to insert screws so that they are flush, one of the

5 settings must be chosen on the torque setting ring 2 :

Low setting, e. g., small screws, soft materi-

als.

High setting, e. g., large screws, hard materi-

als.

When the setting is correct, the overload clutch opens as

soon as the screw has been screwed in flush into the

material or as soon as the set torque has been reached.

When unscrewing screws, select a higher setting or set

to the drill symbol. The proper setting is best determined

with practical trials.

Drilling

Set the torque setting ring 2 to the drill sym-

bol.

Hammer Drilling (PSB..)

Set the torque setting ring 2 to the hammer

symbol.

Replacing the Drill Chuck

To change the chuck, place the setting ring 2 in

the

position.

The locking screw 6 safeguards the drill spindle from

loosening in the chuck. Open the chuck fully and com-

pletely unscrew the locking screw 6 (Note: lefthanded

thread!) .

Mounting the drill chuck takes place in the reverse order.

Practical Advice

Use only screwdriver blades/bits that fit properly in

the head of the screw.

It is advisable to first drill a pilot hole before attempt-

ing to screw in large, long screws in hard material.

For drilling in metal, use only flawlessly sharpened

HSS drills. The appropriate quality is guaranteed by

the Bosch accessories program.

Maintenance and Cleaning

Before any work on the machine itself, remove

the battery.

For safe and proper working, always keep the

machine and the ventilation slots clean.

If the machine should fail despite the rigorous manufac-

turing and testing procedures, repair should be carried

out by an authorised after-sales service centre for Bosch

power tools.

In all correspondence and spare parts orders, please al-

ways include the 10-digit order number given on the

nameplate of the machine.
