9. Hold the air chipping hammer firmly with both hands and put the chisel tip up
against the workpiece you want to chip.
10. Press the trigger (3) and slowly move the air chipping hammer along the
workpiece. Do not push down the chisel against the workpiece. If the results
are not satisfactory, check the chisel for wear.

exchanging the chisel, when not using the unit, after finished working and
when applying maintenance work. Press the trigger in order to remove any
remaining air from the chipping hammer.

Air Pressure and Air Volume

Operate the air chipping hammer with a pressure of 6 bar (90 psi). Exceeding
the max. permitted pressure level of 8 bar will significantly reduce the lifetime
of the tool. Operate the air chipping hammer using a compressor with an air
suction capacity of > 350 l/min. The ideal capacity is provided by compressors
with a suction capacity greater than 400 l/min.
Only use air hoses with an inner diameter of at least 9 mm. When setting up
the air pressure, always keep in mind that the pressure will decrease by
approx. 0.6 bar when using a 10 m long hose with an inner diameter of 9 mm.
