Rotary drill
Weight according to
EPTA-Procedure 01:2014
Protection class
The specifications apply to a rated voltage [U] of 230 V. These spe-
cifications may vary at different voltages and in country-specific mod-
els.
Noise/vibration information
Noise emission values determined according to
EN 62841-2-1.
Typically, the A-weighted noise level of the power tool is:
Sound pressure level 85 dB(A); sound power level
96 dB(A). Uncertainty K = 5 dB.
Wear hearing protection!
Vibration total values a

The vibration level and noise emission value given in these
instructions have been measured in accordance with a
standardised measuring procedure and may be used to com-
pare power tools. They may also be used for a preliminary
estimation of vibration and noise emissions.
The stated vibration level and noise emission value repres-
ent the main applications of the power tool. However, if the
power tool is used for other applications, with different ap-
plication tools or is poorly maintained, the vibration level
and noise emission value may differ. This may significantly
increase the vibration and noise emissions over the total
working period.
To estimate vibration and noise emissions accurately, the
times when the tool is switched off or when it is running but
not actually being used should also be taken into account.
This may significantly reduce vibration and noise emissions
over the total working period.
Implement additional safety measures to protect the oper-
ator from the effects of vibration, such as servicing the
power tool and application tools, keeping their hands warm,
and organising workflows correctly.
Assembly
Pull the plug out of the socket before carrying out any
u
work on the power tool.
Auxiliary Handle (see figure A)
Only use your power tool with the auxiliary handles
u
(2) and (4).
Screw the auxiliary handle (2) into the thread (3) on the mo-
tor housing.
The auxiliary handle (4) can be continuously rotated through
360°.

Wear protective gloves when changing tools. The drill
u
chuck may heat up significantly when it is used for long
periods.
/ II
Keyed chuck with automatic lock (see figure B)
Open the keyed chuck (1) by turning it until the tool can be
inserted.
Insert the tool. Insert the drill chuck key (9) into the corres-
ponding holes of the keyed chuck (1) and clamp the tool
evenly.
Changing the drill chuck (see figure C)
Pull the plug out of the socket before carrying out any
u
work on the power tool.
Removing the securing screw
A securing screw (10) protects the keyed chuck (1) from be-
2
ing accidentally separated from the drill spindle.
Open the keyed chuck (1) fully and unscrew the securing
screw (10) clockwise. Note that the securing screw has a
left-hand thread.
When the securing screw (10) is securely seated, place a
screwdriver on the screw head and undo the securing screw
by hitting the handle of the screwdriver.
Removing the drill chuck
To remove the drill chuck (1), place an open-ended spanner
(SW 17) onto the nut on the drive spindle.
Hold the keyed chuck firmly in one hand and use your other
hand to turn the open-ended spanner anticlockwise until the
drill chuck comes away from the drill spindle cone.
Installing the drill chuck
Keep the cone of the drill spindle and the hole of the
u
drill chuck free of grease and dirt.
To install the keyed chuck (1), turn the nut on the drive
spindle clockwise as far as it will go.
Push the keyed chuck onto the drive spindle until it is se-
curely seated, but do not use force when doing so.
Use a rubber hammer to lightly hit the front side of the keyed
chuck (1) in order to ensure that the keyed chuck is securely
seated. When doing so, ensure that the clamping jaws of the
keyed chuck do not protrude to avoid damaging the chuck.
Installing the securing screw
Screw the securing screw (10) anticlockwise into the open
keyed chuck. Always use a new securing screw because a se-
curing adhesive substance is applied on its thread and is
rendered ineffective after repeated use.
Dust/Chip Extraction
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.
