6.5 Correct operation
6.5.1 Working angle
n
Always position the tool so that it hits the material to
be broken at a right angle.
90°
If you do not do this, the hydraulic breaker will wear
faster and damage will occur after a while.
n
Slightly swing the hydraulic breaker to and fro when
carrying out the hammer impacts, but never swing it
through more than approx.5°.
90°
-5˚
+5˚
This swing action enables any dust under the tip or
the cutter of the working tool to escape. Otherwise a
layer of dust is created which would prevent the full
percussion energy being transferred to the material to
be broken. The tip of the working tool then becomes
hot and loses its hardness.
Larger swing angles would lead to bending loads and
damage to the working tool and the hydraulic
breaker.
6.5.2 Advance
Select the distance marked with "V“ such that the frag-
ment is released within 30seconds. If this is not the
case decrease the advance or apply the tool again to an-
other location.
Excessive advances do not improve the working result.
The working tool will then penetrate the material without
a satisfactory breaking result. The tip of the working tool
then becomes hot and loses its hardness. Work step by
step to achieve the optimum work result.
n
Start near the edge of the material to be broken and
work your way back to its centre.
V
6.5.3 Impact time
n
Never apply the hydraulic breaker to the same point
for more than 30seconds.
30 s
n
If the material fails to break, apply the tool to a new
location.
