Safety and operating instructions
Always connect T and P hoses before starting.
♦

Starting a cut

♦ Stand in a stable position with your feet well away
from the inserted tool.
♦
Press the machine against the working surface
before you start.
♦ Start collaring at such a distance from the edge
that the machine is capable of breaking the
material without leverage.
♦ Never break off too large pieces. Adjust the
breaking distance (A) so that the inserted tool does
not get stuck.

Breaking

♦ Let the machine do the work; do not press too
hard. The vibration-reducing handle must
absolutely not be pressed all the way down to the
base.
♦ Hydraulic breakers with vibration-reducing
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 for
♦
example granite and reinforcing iron (re-bar) which
would cause substantial vibrations.
Any form of idling, operating without insertion tool
♦
or operating with an uplifted machine must be
avoided.
When the machine is lifted, the start and stop
♦
device must not be activated.
Check regularly that the machine is well lubricated.
♦
Never use the machine as a hand held impact
♦
tool.
♦ Ensure that the work piece is securely fixed.
