The vibration level given in this information sheet has been
measured in accordance with a standardised test given in
EN 60745 and may be used to compare one tool with anoth-
er. It may be used for a preliminary assessment of exposure.
The declared vibration emission level represents the main ap-
plications of the tool. However if the tool is used for different
applications, with different accessories or insertion tools or is
poorly maintained, the vibration emission may differ. This
may significantly increase the exposure level over the total
working period.
An estimation of the level of exposure to vibration should also
take into account the times when the tool is switched off or
when it is running but not actually doing the job. This may sig-
nificantly reduce the exposure level over the total working
period.
Identify additional safety measures to protect the operator
from the effects of vibration such as: maintain the tool and the
accessories, keep the hands warm, organisation of work pat-
terns.
Assembly
 Before any work on the machine itself, pull the mains
plug.
Auxiliary Handle (see figure A)
 Operate your machine only with the auxiliary handle 9.
 Before any work, make sure that the wing bolt 21/18 is
tightened. Loss of control can cause personal injury.
Turn the wing bolt 21/18 counterclockwise and guide the
auxiliary handle 9 over the drill chuck onto the spindle collar
of the power tool.
You can swivel the auxiliary handle 9 in order to achieve a safe
work posture that minimises your fatigue.
Swivel the auxiliary handle 9 to the required position and
retighten the wing bolt 21/18 in clockwise direction.
Adjusting the Drilling Depth (see figure B)
The required drilling depth X can be set with the depth stop
23.
Press the button for depth stop adjustment 22 and insert the
depth stop into the auxiliary handle 9.
The knurled surface of the depth stop 23 must face down-
ward.
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.
Drill Assistant
Attaching the Drill Assistant (see figures C–D)
The Drill Assistant 10 can be used with and without dust col-
lection device 13. Use of the dust collection device 13 is lim-
ited to drill bits with a diameter of 12 mm and a length of
120 mm.
Attach the dust collection device 13 to the mounting 26.
Press the unlocking button 8 to release the Drill Assistant 10
from its parked position.
Bosch Power Tools
Guide the Drill Assistant 10 over the drill chuck onto the spin-
dle collar of the power tool.
Lock it by turning the wing bolt 18 in clockwise direction.
Adjusting the Drilling Depth (see figures E – F)
Mount the drill bit (see section "Changing the Tool").
You can use the setting ring 17 to set the required drilling
depth X.
Unlock the setting ring 17 by turning it to the left
the dust box 11 or the mounting 26 flush against the wall or
workpiece. Move the tip of the drill bit to the wall or work-
piece.
Slide the setting ring 17 backward until the distance matches
the required drilling depth X or place a wall plug on the rail
and slide the setting ring 17 backward to the wall plug. Lock
the setting ring 17 by turning it to the right
plug out of the rail again. The drilling depth now matches the
set length X on the rail.
Note: It is important to have the exact drilling depth when us-
ing wall plugs. If the drilled hole is too deep, the wall plug will
slip too far into the wall or workpiece. If the hole is too small,
the wall plug will stick out.
Emptying the Dust Box (see figure G)
The dust box 11 is enough for drilling about 25 holes in ma-
sonry at a drilling depth of 30 mm with a drill bit diameter of
6 mm.
– To remove the dust box 11, press the side-mounted un-
locking buttons 12 and pull the dust box off in a downward
direction.
– Empty the dust box 11 and reinsert it (until it can be heard
to engage).
Removing the Drill Assistant
– Press and hold the clip 16 of the dust collection device 13
and pull the dust box 13 off toward the front.
– Turn the wing bolt 18 counterclockwise until the auxiliary
handle 9 can be moved and pull the auxiliary handle 9 off
the power tool.
– Unlock the setting ring 17 by turning it to the left
– Hold the auxiliary handle 9 in place and slide the rail to-
wards the auxiliary handle until it can be heard to engage.
Dust Extraction/Dust Box
 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.
– Use a dust extraction system suitable for the material
being worked.
– 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.
