5. Before starting the equipment

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 fl exible pneumatic pipe
(internal Ø 10 mm) and quick-action coupling to
connect the chisel hammer to a powerful com-
pressor 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. Operation

Observance of the following maintenance inst-
ructions will ensure that this quality tool gives you
years of troublefree service.
Clean the tool thoroughly as soon as you are fi ni-
shed with your work.
Regular lubrication is vital for the long-term, reli-
able 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 fi tted 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 con-
nection. 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.
