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 signifi cantly 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 signifi cantly 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, fi re and/or serious injury.
Save all warnings and instructions for future reference.
ROTARY HAMMER SAFETY WARNINGS
Wear ear protectors when impact drilling. Exposure to
noise can cause hearing loss.
Use auxiliary handle(s), if 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. Cutting accessory contacting
a „live" wire may make exposed metal parts of the power
tool „live" and could give the operator an electric shock.
ADDITIONAL SAFETY AND WORKING INSTRUCTIONS
Use protective equipment. Always wear safety glasses when
working with the machine. The use of protective clothing is
recommended, such as dust mask, protective gloves, sturdy
non-slip footwear, helmet and ear defenders.
The dust produced when using this tool may be harmful to
health. Do not inhale the dust. Wear a suitable dust
protection mask.
Do not machine any materials that present a danger to
health (e.g. asbestos).
Switch the device off immediately if the insertion tool stalls!
Do not switch the device on again while the insertion tool is
stalled, as doing so could trigger a sudden recoil with a high

reactive force. Determine why the insertion tool stalled and
rectify this, paying heed to the safety instructions.
The possible causes may be:
• it is tilted in the workpiece to be machined
• it has pierced through the material to be machined
• the power tool is overloaded
Do not reach into the machine while it is running.
The insertion tool may become hot during use.
WARNING! Danger of burns
• when changing tools
• when setting the device down
Chips and splinters must not be removed while the machine
is running.
When working in walls ceiling, or fl oor, take care to avoid
electric cables and gas or waterpipes.
Clamp your workpiece with a clamping device. Unclamped
workpieces can cause severe injury and damage.
When working with large drill diameters, the auxiliary handle
must be fastened in a right angle with the main handle (see
illustrations, section "Twisting the handle").
Remove the battery pack before starting any work on the
machine.
Do not dispose of used battery packs in the household
refuse or by burning them. Milwaukee Distributors offer to
retrieve old batteries to protect our environment.
Do not store the battery pack together with metal objects
(short circuit risk).
Use only System Milwaukee 28 V chargers for charging
System Milwaukee 28 V battery packs. Do not use battery
packs from other systems.
Never break open battery packs and chargers and store
only in dry rooms. Keep dry at all times.
Battery acid may leak from damaged batteries under
extreme load or extreme temperatures. In case of contact
with battery acid wash it off immediately with soap and
water. In case of eye contact rinse thoroughly for at least 10
minutes and immediately seek medical attention.
No metal parts must be allowed to enter the battery section
of the charger (short circuit risk).
SPECIFIED CONDITIONS OF USE
The battery rotary pneumatic hammer can be used for
hammer drilling and drilling in wood, metal as well as plastic
for independent use away from mains supply.
Do not use this product in any other way as stated for
normal use.

BATTERIES
New battery packs reach full loading capacity after 4 - 5
chargings and dischargings. Battery packs which have not
been used for some time should be recharged before use.
Temperatures in excess of 50°C (122°F) reduce the
performance of the battery pack. Avoid extended exposure
to heat or sunshine (risk of overheating).
The contacts of chargers and battery packs must be kept
clean.
For an optimum life-time, the battery packs have to be fully
charged, after use.
To obtain the longest possible battery life remove the battery
pack from the charger once it is fully charged.
For battery pack storage longer than 30 days:
Store the battery pack where the temperature is below 27°C
and away from moisture
Store the battery packs in a 30% - 50% charged condition
Every six months of storage, charge the pack as normal.
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 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 Article No. as well as the machine type
printed 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.
