Bosch Power Tools
Assembly
Before any work on the machine itself, pull the mains
plug.
Auxiliary Handle
Operate your machine only with the auxiliary handle
10.
Changing the position of the auxiliary handle
(see figure A)
The auxiliary handle
10
can be set to any position for a secure
and low-fatigue working posture.
– Turn the wing bolt for adjustment of the auxiliary handle
9
in anticlockwise direction and set the auxiliary handle
10
to the required position. Then tighten the wing bolt
9
again
in clockwise direction.
Adjusting the Drilling Depth (see figure B)
The required drilling depth
X
can be set with the depth stop
11
.
– Press the button for the depth stop adjustment
8
and in-
sert the depth stop into the auxiliary handle
10
.
The knurled surface of the depth stop
11
must face down-
ward.
– Insert the SDS-plus drilling tool to the stop into the SDS-
plus tool holder
1
. Otherwise, the movability of the SDS-
plus drilling tool can lead to incorrect adjustment of the
drilling depth.
– Pull out the depth stop until the distance between the tip of
the drill bit and the tip of the depth stop corresponds with
the desired drilling depth
X
.
Selecting Drill Chucks and Tools
For hammer drilling, SDS-plus tools are required that are in-
serted in the SDS-plus drill chuck.
For drilling without impact in wood, metal, ceramic and plas-
tic as well as for screwdriving, tools without SDS-plus are
used (e.g., drill bits with cylindrical shank). For these tools, a
keyless chuck or a key type drill chuck are required.
Changing the Key Type Drill Chuck
To work with tools without SDS-plus (e.g., drills with cylindri-
cal shank), a suitable drill chuck must be mounted (key type
drill chuck or keyless chuck, accessories).
Mounting the Key Type Drill Chuck (see figure C)
– Screw the SDS-plus adapter shank
15
into a key type drill
chuck
14
. Secure the key type drill chuck
14
with the se-
curing screw
13
.
Please observe that the securing
screw has a left-hand thread.
Inserting the Key Type Drill Chuck (see figure D)
– Clean the shank end of the adapter shank and apply a light
coat of grease.
– Insert the key type drill chuck with the adapter shank into
the tool holder with a turning motion until it automatically
locks.
– Check the locking effect by pulling the key type drill chuck.
Removing the Key Type Drill Chuck
– Push the locking sleeve
3
toward the rear and pull out the
key type drill chuck
14
.
Changing the Tool
The dust protection cap
2
largely prevents the entry of drilling
dust into the tool holder during operation. When inserting the
tool, take care that the dust protection cap
2
is not damaged.
A damaged dust protection cap should be changed im-
mediately. We recommend having this carried out by
an after-sales service.
Inserting SDS-plus Drilling Tools (see figure E)
The SDS-plus drill chuck allows for simple and convenient
changing of drilling tools without the use of additional tools.
– Clean and lightly grease the shank end of the tool.
– Insert the tool in a twisting manner into the tool holder until
it latches itself.
– Check the latching by pulling the tool.
As a requirement of the system, the SDS-plus drilling tool can
move freely. This causes a certain radial run-out at no-load,
which has no effect on the accuracy of the drill hole, as the
drill bit centres itself upon drilling.
Removing SDS-plus Drilling Tools (see figure F)
– Push back the locking sleeve
3
and remove the tool.
Inserting Drilling Tools without SDS-plus
Note:
Do not use tools without SDS-plus for hammer drilling!
Tools without SDS-plus and their drill chucks are damaged by
hammer drilling.
– Insert a key type drill chuck
14
(see “Changing the Key
Type Drill Chuck”, page 8).
– Open the key type drill chuck
14
by turning until the tool
can be inserted. Insert the tool.
– Insert the chuck key into the corresponding holes of the
key type drill chuck
14
and clamp the tool uniformly.
– Set the selector switch
7
to the “Drilling” symbol.
Removing Drilling Tools without SDS-plus
– Turn the sleeve of the key type drill chuck
14
with the drill
chuck key in anticlockwise direction until the drilling tool
can be removed.
Dust Extraction with the Dust Extraction
Attachment (Accessory)
Dust 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 dust can cause
allergic reactions and/or lead to respiratory infections of
the user or bystanders.
Certain dust, such as oak or beech dust, is considered car-
cinogenic, especially in connection with wood-treatment
additives (chromate, wood preservative). Materials con-
taining asbestos may only be worked by specialists.
– As far as possible, use a dust extraction system suitable
for the material.
– Provide for good ventilation of the working place.
– It is recommended to wear a P2 filter-class respirator.
