WARNING!
Ø
Ensure the breaker is used only for suitable
applications.
Ø
Inspect the area of the project prior to operating
the breaker.
Ø
Pay particular attention to the safety of yourself
and others.
5.1 Correct working Methods
1) Prepare the excavator as for normal excavation
work. It is strongly advised that the front screen,
guard and door are closed to protect the operator.
-
Move the excavator to the required position.
-
Engage the parking brake if fitted.
-
Set drive to neutral .
-
Disengage the boom lock if fitted.
-
It is also strongly advised to wear hearing
protection at this point. Anyone in the
surrounding area should also wear protection
to prevent hearing damage.
2) Adjust the excavator manually or using the on-
board computer to produce the correct flow and
pressure for the breaker.
3) Place the tool perpendicular to the material.
-
Avoid small irregularities in the material that
will break easily causing idle strokes or an
incorrect working angle.
4)
Use the excavators boom to press the breaker
firmly against the object. Ensuring that the tool
remains perpendicular to the material
-
Never start the breaker until the correct force
has been applied to the tool.
5)
Start the breaker.
-
Stop the breaker immediately if someone
enters the working area. Whilst working, this
zone is much larger due to possible stone
fragments in the air. A reasonable perimeter
should be created during breaking.
6) Continuously feed the breaker.
-
As the tool penetrates the material the
breaker must also be fed into the material.
Failing to do so will cause idle strokes and
increased wear upon the breaker.
-
A continuous feed at the correct force will
increase the efficiency of the breaker.
7) Ensure the breaker remains perpendicular in
relation to the material.
-
If the material moves or its surfaces
breaks, the breaker should be repositioned
immediately. Failing to do so will cause
increased wear upon the breaker.
8) The breaker should not be worked continuously for
more than 15 seconds.
