Assembly

f Before any work on the machine itself, pull

the mains plug.

Auxiliary Handle (see figure A)

f Operate your machine only with the auxilia-

ry handle 7.

The auxiliary handle 7 can be set to any position

for a secure and low-fatigue working posture.

Turn the bottom part of the auxiliary handle 7 in

counterclockwise direction and swivel the auxil-

iary handle 7 to the desired position. Then

retighten the bottom part of the auxiliary handle

7 by turning in clockwise direction.

Adjusting the Drilling Depth (see figure A)

The required drilling depth X can be set with the

depth stop 8.

Turn the bottom part of the auxiliary handle 7 in

anticlockwise direction and insert the depth

stop 8.

Pull out the depth stop until the distance be-

tween the tip of the drill bit and the tip of the

depth stop correspond with the desired drilling

depth X.

Afterwards, tighten the bottom part of the auxil-

iary handle 7 again by turning in clockwise direc-

tion.

The knurled surface of the depth stop 8 must

face upward.

Changing the Tool

Keyless Chuck (see figure B)

The drill spindle is locked when the On/Off

switch 5 is not pressed. This makes quick, con-

venient and easy changing of the tool in the drill

chuck possible.

Open the keyless chuck 1 by turning in rotation

direction n, until the tool can be inserted. Insert

the tool.

Firmly tighten the collar of the keyless chuck 1

by hand in rotation direction o until the locking

action (“click”) is no longer heard. This automat-

ically locks the chuck.

The locking is released again to remove the tool

when the collar is turned in the opposite direc-

tion.

Key Type Drill Chuck (see figure C)

f Wear protective gloves when changing the

tool. The drill chuck can become very hot

during longer work periods.

Open the key type drill chuck 10 by turning until

the tool can be inserted. Insert the tool.

Insert the chuck key 9 into the corresponding

holes of the key type drill chuck 10 and clamp

the tool uniformly.

Screwdriver Tools (see figure D)

When working with screwdriver bits 11, a uni-

versal bit holder 12 should always be used. Use

only screwdriver bits that fit the screw head.

For driving screws, always position the “Drill-

ing/Impact Drilling” selector switch 2 to the

“Drilling” symbol.

Replacing the Drill Chuck

f Before any work on the machine itself, pull

the mains plug.

f For power tools without spindle lock, the

drill chuck must be replaced by an author-

ised after-sales service agent for Bosch

power tools.

Removing the Drill Chuck (see figure E)

Disassemble the auxiliary handle and set the

gear selector 10 to the centre position between

the 1st and 2nd gear.

Insert a steel pin with a diameter of Ø 4 mm and

approx. 50 mm of length into the drill hole on the

spindle neck in order to lock the drill spindle.

Clamp the short end of an Allen key 13 into the

keyless chuck 1.

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

workbench). Hold the machine firmly and loos-

en the keyless chuck 1 by turning the Allen key

13 in rotation direction n. Loosen a tight-seated

keyless chuck by giving the long end of the Allen

key 13 a light blow. Remove the Allen key from

the keyless chuck and completely unscrew the

keyless chuck.
