WARNING
The vibration emission 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 another. It may be used for a preliminary assessment of exposure.
The declared vibration emission level represents the main applications of the tool. However if the tool is used for different
applications, with different accessories or 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 significantly 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 patterns.
WARNING! Read all safety warnings and all
instructions. Failure to follow the warnings and instructions
may result in electric shock, fire and/or serious injury.
Save all warnings and instructions for future reference.
SAFETY INSTRUCTIONS
Wear ear protectors. Exposure to noise can cause
hearing loss.
Use auxiliary handles supplied with the tool. Loss of
control can cause personal injury.
Hold power tool by insulated gripping surfaces, when
performing an operation where the cutting accessory
may contact hidden wiring or its own cord. Cutting
accessory contacting a „live" wire may make exposed metal
parts of the power tool „live" and could give the operator an
electric shock.
Appliances used at many different locations including open
air should be connected via a residual current device of
30 mA or less.
Always wear goggles when using the machine. It is
recommended to wear gloves, sturdy non slipping shoes
and apron.
Sawdust and splinters must not be removed while the
machine is running.
Always disconnect the plug from the socket before carrying
out any work on the machine.
Only plug-in when machine is switched off.

MAINS CONNECTION
Connect only to single-phase a.c. current and only to
the system voltage indicated on the rating plate. It is
also possible to connect to sockets without an earthing
contact as the design conforms to safety class II.
This is a device for professional use which may slightly
exceed the guide values for current harmonics when it is
connected to the public low voltage mains supply. You
should therefore contact your energy supply company
before you connect the device to the public low voltage
mains supply.
MAINTENANCE
The ventilation slots of the machine must be kept clear at all
times.
Important note! If the carbon brushes are worn, in addition
to exchanging the brushes the tool should be sent to
after-sales service. This will ensure long service life and top
performance.
Use only Milwaukee accessories and Milwaukee spare
parts. Should components need to be replaced which have
not been described, please contact one of our Milwaukee
service agents (see our list of guarantee/service addresses).
If needed, an exploded view of the tool can be ordered.
Please state the machine type printed as well as the six-digit
No. on the label and order the drawing at your local service
agents or directly at: Techtronic Industries GmbH,
Max-Eyth-Straße 10, 71364 Winnenden, Germany.
SYMBOLS
Please read the instructions carefully before
starting the machine.
Always disconnect the plug from the socket
before carrying out any work on the
machine.
Accessory - Not included in standard
equipment, available as an accessory.
Do not dispose of electric tools together
with household waste material! In
observance of European Directive 2002/96/
EC on waste electrical and electronic
equipment and its implementation in
accordance with national law, electric tools
that have reached the end of their life must
be collected separately and returned to an
environmentally compatible recycling
facility.
Class II construction, tool in which
protection against electric shock does not
rely on basic insulation only, but in which
additional safety precautions, such as
double insulation or reinforced insulation,
are provided.
