♦
Make sure that there are no people in the danger
zone.
♦
Start the carrier as instructed by the carrier
manufacturer.
♦
Let the carrier heat up until the operating
temperature prescribed by the carrier manufacturer
has been reached.
♦
Put the carrier in its working position.
♦
Put the working tool on the material to be broken.
Switching the hydraulic
breaker on and off
After properly attaching the hydraulic attachment to
the carrier, the hydraulic attachment can be operated
using the carrier‘s hydraulic system. All functions for
normal carrier operation remain intact.
The hydraulic attachment is switched on and off using
electrical and hydraulic signals.
If you have any questions about electric/hydraulic
commands, consult the carrier manufacturer and/or
the Atlas Copco Customer Center/Dealer in your
area.
♦
Switch the hydraulic attachment on and off, as
described in the carrier‘s operating instructions.
♦
When leaving the driver’s cab, set the safety
switch/lever for the electrical/hydraulic attachment
installation to the „OFF“ position.
Carry out the above actions to prevent any
unintended start-up of the hydraulic attachment.
Functional test
Always carry out a functional test before putting the
hydraulic attachment into use to check that all
hydraulic lines and connections are tight and that the
hydraulic attachment works without any problems.
♦
Prepare the hydraulic attachment so that you can
start using it.
♦
Carry out a couple of test impacts on the material
to be broken.
♦
Check the hydraulic lines and make sure that the
hydraulic attachment works without any problems.
♦
Immediately switch off the hydraulic attachment if
oil escapes from the hydraulic lines or if other
defects in functioning occur.
♦
Depressurise the hydraulic system (see chapter
Depressurising the hydraulic system).
♦
Only use the hydraulic attachment again after
having repaired all leaks and operating defects.
Correct operation
Working angle
♦
Always position the tool so that it hits the material
to be broken at a right angle.
If you do not do this, the hydraulic breaker will wear
faster and damage will occur after a while.
♦
Slightly swing the hydraulic breaker to and fro
when carrying out the hammer impacts, but never
swing it through more than approx. 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.
