2.4 Emissions
The values stated are emission levels. Although there is a correlation between emission and imission level, it
cannot be reliably derived from this whether additional precautions are necessary. Factors influencing the current
immission level existing at the workplace comprise the duration of exposure, the room characteristic, other source
of noise, etc. such as e.g. the number of machines and other adjacent machining operations. In addition, the
permissible immission level may differ from country to country. This information is nevertheless suitable for
providing the machine user with an improved assessment of the hazard and risk.

3Safety information
Danger
Electrical appliances may be
dangerous if used incorrectly.
Therefore, always observe the
safety instructions summarised in
this chapter and the safety
regulations applicable in the
respective country of use!
3.1 Safety instructions for all types of work
- Wear ear protectors during the use of impact
drill drivers (machines with the designation
ASB). Exposure to noise can cause loss of hearing.
- Make use of the additional handle supplied with
the appliance. Loss of control can lead to injuries.
- Always hold the appliance by the insulated
gripping surfaces when carrying out work
during which the bit may hit concealed power
lines. Cutting accessory contacting a "live" wire
may make exposed metal parts of the power tool
"live" and could give the operator an electric shock.
3.2 Safety instructions for the use of long drill bits
- Always start drilling at low speed and with the
drill bit in contact with the workpiece.
- On no account may you work at a speed that
exceeds the maximum speed permitted for the
drill bit. At higher speeds, the drill bit can easily

-20-
bend if allowed to turn freely (without contact with
the workpiece); this can lead to injuries.
- Do not apply excessive pressure and only apply
pressure in the longitudinal direction to the drill
bit. Drill bits can bend and thus break or lead to a
loss of control and injuries.
3.3 Additional safety instructions
- Ensure that the machine is switched off when you
push in the rechargeable battery.
- Remove the rechargeable batteries from the
machine before carrying out any setting, retooling,
maintenance or cleaning tasks.
- Dust originating from materials such as leaded
paint, some types of wood, minerals and metal can
be harmful to health. Touching or inhaling these
dusts can cause allergic reactions and/or
respiratory disorders in the user or persons staying
in the vicinity.
- As far as possible, make use of a dust extraction
system.
- Provide for good ventilation of the workplace.
- It is recommended to wear a respirator mask with
filter class P2.
- Observe the regulations valid in your country for the
materials to be machined.
- Secure the workpiece against shifting, e. g. by
means of fastening devices.
- LED light (Fig. 1, 7): Do not directly look at the LED
radiation with optical instruments.

Opening the chuck: Turn the chuck (1) in direction of
rotation .
Tensioning the tool: Turn the sleeve in direction
until the perceptible mechanical resistance has been
overcome. Caution! The tool is not yet tensioned!
Continue turning forcefully (a "clicking" sound must be

-22-
heard while doing so) until it is not possible to turn any
further - only now the tool is reliably tensioned.
In case of a soft tool shaft, it may be necessary to
retension after a short drilling time.
Notes on ASB18 M and A18
•The ratchet sound that may be heard after
opening the chuck (functional) is switched off by
counter-rotating the sleeve.
Cleaning: Hold the machine occasionally with the
