3. Proper use

The chisel hammer is a pneumatic tool for general use. It can be used, for example, to cut grooves, to remove tiles or plaster, to knock holes through walls, to cut metal sheet and plate, and to knock off bolts and rivets.

The exhaust air leaves the housing to the front.

The equipment is to be used only for its prescribed purpose. Any other use is deemed to be a case of misuse. The user / operator and not the manufacturer will be liable for any damage or injuries of any kind caused as a result of this.

Please note that our equipment has not been designed for use in commercial, trade or industrial applications. Our warranty will be voided if the machine is used in commercial, trade or industrial businesses or for equivalent purposes.

Repairs and maintenance work are to be carried out only by authorized specialist workshops.

Please note!

The power of the tool will be reduced if you use a hose that has too small an inner diameter or which is too long.

5. Putting into operation

Screw the supplied plug-in nipple into the air connection after you have wound 2 to 3 layers of sealing tape around the thread. Insert the chisel of your choice in the hexagon tool holder. Slide the clamping spring over the chisel. Holding the clamping spring by its front clip, screw the clamping spring onto the thread of the cylinder as far as the stop. Use a flexible pneumatic pipe (internal 0 10 mm) and quick-action coupling to connect the chisel hammer to a powerful compressor or compressed-air system. Make sure that the air regulating screw (2) is open. Move the chisel hammer toward the workpiece and press the trigger lever (1) to start the tool.

To change the chisel, disconnect the tool from the air supply. Holding the clamping spring by its rear clip, screw the clamping spring off the cylinder of the chisel hammer. The chisel can be changed as described above.

The chisel shaft should be lubricated occasionally with a little standard grease.

6. Maintenance and cleaning

Observance of the following maintenance instructions will ensure that this quality tool gives you years of troublefree service. Clean the tool thoroughly as soon as you are finished with your work.

Regular lubrication is vital for the long-term, reliable operation of your chisel hammer. Use only special tool oil for this purpose.

You can choose from the following options for lubricating the tool:

6.1 By mist oiler

A complete conditioning unit includes a mist oiler and is fitted to the compressor.

6.2 By hand

Each time before you use your impactscrewdriver, feed 3-5 drops of special tool oil into the air connection. If the pneumatic tool has not been used for several days, you must feed 5-10 drops of oil into the air connection before you switch on. Keep your pneumatic tool in dry rooms only.
