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.
2.4.1 Noise emission specifications
Noise emission values determined according to EN 62841-1 and EN 62841-2-1:
Sound pressure level (LpA)
Sound power level (LWA)

2.6 Use according to intended purpose
The drill driver A12 M is suitable for drilling in metal,
wood, plastic and similar materials as well as for
screwing and tapping.
Any other use than described above is not
permissible. The manufacturer cannot be held liable
for any damage arising from such other use.
In order to use the appliance as intended, you must
comply with the operating, maintenance and repair
instructions specified by MAFELL.
Corrective maintenance work must be carried out by
MAFELL authorised dealers or MAFELL customer
service stations.
The safety instructions applicable in the respective
country of use as well as other generally recognised
rules pertaining to safety and occupational health
must be observed.
Unauthorized changes to the appliance shall rule out
any manufacturer liability for damages resulting
thereof.
Only use original Mafell / CAS rechargeable batteries
and accessories.
3Safety instructions
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 drill
drivers. Exposure to noise can cause loss of
hearing.
- 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
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, 10): Do not directly look at the
LED radiation with optical instruments.

5.7 Tool change
Only use high-grade tools, which
are suitable for the forces and
torques occurring! Broken tools will
lead to a machine defect. If repairs
are necessary, contact the
customer service stations for
MAFELL electrical tools.

chuck. Turn the chuck (1) in direction of rotation
until the tool is firmly mounted.
5.7.2 Angle attachment
The angle attachment can be used to work at right
angles to the screwdriver axle.
Mount the bits directly by means of the ¼‘‘ hexagon
adapter or by attaching the chuck or bit holder.

6Service and maintenance
Danger
Unplug the rechargeable battery for
all service work.
MAFELL machines are designed to be low in
maintenance.
Always keep the appliance clean.
Should the appliance fail despite thorough
manufacturing and testing procedures, the repair
must be carried out by an authorised customer
service station for MAFELL electrical tools.
Store the appliance in a dry and frost-proof place.
Only use MAFELL accessories and spare parts. Have
components, the replacement of which has not been
described, replaced at a MAFELL customer service
station.
6.1 Storage
Clean the machine thoroughly if the machine is not
used for a longer period of time. Spray blank metal
parts with a rust-proofing agent.
6.2 Transport
The included Li-ion rechargeable batteries are subject
to the requirements of dangerous goods legislation.
The rechargeable batteries can be transported by the
user on the road without any further requirements.
For the dispatch by third parties (e.g.: air transport or
forwarding agent), special requirements for packaging
and labelling must be observed. In this case, a
dangerous goods expert must be consulted when
preparing the package.
Only dispatch rechargeable batteries if their housing
is undamaged. Tape open contacts and pack the
rechargeable battery so that it does not move in the
packaging.
Please also observe any further national regulations.
6.3 Disposal of rechargeable batteries/batteries
Electrical tools, rechargeable
batteries, accessories and
packaging should be recycled in an
environmentally friendly manner.
Do not dispose of electrical tools together with
domestic waste!

According to the European
Directive 2002/96/EC, power tools
that are no longer serviceable, and
according to the European
Directive 2006/66/EC, defective or
used rechargeable
batteries/batteries must be
collected separately and recycled
in an environmentally sound
manner.
Return unusable rechargeable batteries/batteries
directly to:

7Troubleshooting
Danger
Determining the causes for existing defects and eliminating these always requires
increased attention and caution.
If the machine switches off automatically, the electronic system has activated self-protection mode.
Despite this protective function, overload and as a consequence damage to the machine may occur during
certain applications.
Some of the most frequent defects and their causes are listed in the following chart. In case of other defects,
please contact your dealer or the MAFELL customer service directly.
Defect
Cause
Remedy
Machine switches off and an LED
on the capacity display (9) flashes.
Rechargeable battery is almost
empty.
The electronic system protects
the rechargeable battery from
deep discharge.
Charge the rechargeable battery.
The machine switches off and
cannot be switched on again. A
warning signal sounds and the LED
light (10) flashes.
Overload
A sustained load has overheated
the machine or the rechargeable
battery.
Signal goes out after releasing
the switch trigger (11).
Allow the machine and the
rechargeable battery to cool
down.
Note: The machine cools down
faster when it is allowed to idle
after it is switched on again.
Machine switches off. A warning
signal sounds and the LED light
(10) flashes.
Machine restarts when it is switched
on again.
Excessive current rating.
This leads to the machine being
switched off, e.g. in the event of
prolonged blockage.
Switch off the machine by
releasing the switch trigger (11).
Afterwards, you can switch the
machine back on again and
resume work.
Try to avoid further blockages.
