Operating

Preparation before starting

The following checks should be made each time you
start to use the breaker. All these checks concern the
serviceability of the breaker. Some concern your
safety:
♦ Clean all safety stickers. Replace any that are
missing or cannot be read.
Inspect the hoses generally for signs of damage.
♦
Inspect the working tool for wear and damage.
♦
Do not use an excessively worn or damaged tool.
Connect the tool.
♦
Ensure that the hydraulic couplings are clean and
♦
fully serviceable.
Never invert the breaker without first isolating it
♦
from the power source. The working tool might
be ejected violently while connecting it, if the
breaker is connected to the power source.
Ensure that any power source you plan to use is
♦
compatible with the breaker model used (see the
"Technical data"). Use the recommended oil flow
divider, if the flow from the power source can
exceed the maximum allowed oil flow.
♦ Never exceed the maximum relief valve setting
stated on the tool.
♦ 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.

Safety and operating instructions
♦ 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.
