Stop; Starting A Cut; Operation; When Taking A Break - Atlas Copco LH 11 Instrucciones De Seguridad Y De Funcionamiento

Safety and operating instructions

Stop

► Release the trigger. Press the breaker against
the surface, until the breaker has stopped
completely.
► Stop the power source.
► Disconnect the hoses and fit the protective caps
to the quick-release couplings.

Starting a cut

► Stand steady and make sure that your feet and
hands are at a safe distance from the working
tool.
► Press the machine against the surface of the
workpiece before starting.
► Adjust the breaking distance (A) so that the
working tool does not get stuck.
► Do not try to cut too big a bite.
► Trying to loosen a working tool that is stuck will
expose the operator to unnecessary vibrations.

Operation

► Let the machine do the work; do not press too
hard. The vibration-absorbing handle must
absolutely not be pressed all the way down to
the base.
► Hydraulic breakers with vibration-absorbing
handles: The feed force should be adapted so
that the handles are pressed down "half way".
The best vibration damping and breaking effect
is achieved at this position.
► Avoid working in extremely hard materials e.g.
granite and reinforcing iron (reinforcement bar),
which would cause substantial vibrations.
► Any form of idling, operating without working tool
or operating without adapted feed force must be
avoided.
► When no feed force is applied, the start and stop
device must not be activated.
► Check regularly that the machine is well
lubricated.

When taking a break

► During all breaks you must put the machine
away so that there is no risk that it will be
unintentionally started.
► In the event of a longer break or when leaving
the workplace: Switch off the hydraulic oil supply
and then bleed the machine by activating the
start and stop device.
