Residual risks
Even if you use the equipment in accordance
with the instructions, certain residual risks
cannot be eliminated. The following hazards may
arise in connection with the equipment's
construction and layout:
1. Lung damage if no suitable protective dust mask
is used.
2. Damage to hearing if no suitable ear protection is
used.
3. Health damage caused by hand-arm vibrations if
the equipment is used over a longer period or is
not properly guided and maintained.
Air supply:
Via a compressed air source with pressure setting
function, e.g. a compressor. Before starting up,
please also read section 8 "Care and maintenance".
Performance values of the compressor:
The compressor used should have a tank volume of
at least 50 liters and a motor rating of approx. 2.2 kW.
Setting values for work with the suction spray
gun:
Set a maximum working pressure of 6.3 bar at your
compressed air supply.
6. Starting up (Fig. 3)
Screw the supplied nipple (4) into the air connection
after you have wound 2-3 layers of sealing tape
around the thread. Plug the required chisel into the
hexagon mount of the chisel hammer. Slip the
tensioning spring (5) over the chisel. Turn the
tensioning spring onto the thread of the cylinder (1) as
far as the stop. As you do this, hold the tensioning
spring by the front arm.
Connect the chisel hammer to a compressor or
compressed air network with matching power. Do this
with a flexible compressed air hose
(Ø 10 mm internal) with quick-lock coupling. Make
sure that the air regulation screw (3) is adjusted so
that air can flow through. Move the chisel hammer

hammer by holding it by its rear arm. The chisel can
now be changed as described above.
The chisel shaft should be lubricated with a little
normal lubricating grease from time to time.
