Total vibration values (vector sum in the three axes)
determined according to EN 60745.
Chiselling:
Vibration emission value ah …………………………………………. 6,2 m/s2

Uncertainty K= ………………………………………………………….. 0,5 m/s2

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 eff ects of vibration such as: maintain the tool and the accessories, keep the hands warm, organisation of work patterns.

WARNING Read all safety warnings, instructions, illustrations and specifications provided with this power tool. Failure to follow all instructions listed below may result in electric shock, fi re and/or serious injury.

Save all warnings and instructions for future reference.

SAFETY INSTRUCTIONS FOR BREAKER HAMMER

Wear ear protectors. Exposure to noise can cause hearing loss.
Use auxiliary handle(s), if supplied with the tool. Loss of control can cause personal injury.
Hold the power tool by insulated gripping surfaces only, 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.

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

Keep mains lead clear from working range of the machine. Always lead the cable away behind you.
When working in walls ceiling, or floor, take care to avoid electric cables and gas or waterpipes.
Always disconnect the plug from the socket before carrying out any work on the machine.
Always keep a safe footing and hold machine with both hands. Keep children or animals away from working area.

Do not direct the machine towards people standing close whilst it is operating. The inserted tool could be catapulted out and cause serious injuries.

Ensure that nobody is at risk of materials being catapulted out or falling. Always work carefully and attempt to anticipate potential dangers.

Put down the machine carefully. Do not throw the machine to the ground or drop it from great heights. If it is thrown to the ground, the machine may injure others or suffer damage itself.

SPECIFIED CONDITIONS OF USE

The hammer can be used for chiselling in stone and concrete.
Do not use this product in any other way as stated for normal use.

MAINS CONNECTION

Temporary voltage peaks cause voltage fluctuations and may affect other electrical products on the same circuit. Connect the machine to a power supply with a maximum impedance of 0.32 Ω to minimise voltage fluctuations.

Appliances used at many different locations including wet room and open air must be connected via a residual current device (FI, RCD, PRCD) of 30mA or less.

Connect only to single-phase AC system voltage as 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.

Make sure the machine is switched off before plugging in.

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.

TRANSPORT, HANDLING AND STORAGE

The machine is heavy. It may cause serious injuries if it is dropped.

The machine has no lifting or lashing points.

Lift the machine using the additional handle and place it on a suitable means of transport.

Secure the machine whilst it is being lifted, transported or stored to prevent it tipping over, falling or slipping.

Always allow the machine to cool down before placing it in storage.

Store the machine in a locked, clean, dry place which is protected from frost and inaccessible for children.

CHANGING THE TOOL

See the picture section for instructions on changing the tool.

The inserted tool must be suitable for the tool mounting.

The shaft of the inserted tool must be undamaged.

The inserted tool must be adequately sharp to prevent recoil.

The inserted tool must be suitable for the planned work.

After inserting the tool, check whether it has been locked correctly

COLD HAMMERING

If the tool is stored for a long period of time or at cold temperatures, the lubrication may become stiff and the tool may not hammer initially or the hammering may be weak. If this happens:

Insert a bit or chisel into the tool.
Run the tool against a scrap piece of concrete.
Pull and release the trigger every few seconds.

After 15 seconds to 2 minutes, the tool will start hammering normally. The colder the hammer is, the longer it will take to warm up.

Low temperatures have an influence on the lubricants in the chipping hammer. These become viscous, making it more difficult for the entire impact system to start.

We recommend storing the chipping hammer where temperatures will not be below minus 15°C when the machine is started.

To protect the electronics in the device, the overload protector (“Overload”) may respond and switch the device off .

If the overload protector has switched the device off , you will need to wait for min. 30 seconds.

If you attempt to start the device before this time has elapsed, the time until the device can be restarted will begin over again!

MAINTENANCE

The ventilation slots of the machine must be kept clear at all times.

Grease the machine at the lubricating nipple every 40 h, ~ 6 months of service (see picture section).

If the supply cord of this appliance is damaged, it must only be replaced by a repair shop appointed by the manufacturer, to avoid hazardous situations.

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.
