Operating
Starting a cut
◆
Stand in a stable position with feet well away
from the working tool.
◆
Press the machine against the working surface
before starting.
◆
The impact unit is activated when the machine
is pressed down and loaded. When the
machine is lifted, the impact unit disengages
automatically.
◆
The working speed of the machine is controlled
via the throttle lever.
◆
Start collaring at such a distance from the edge
that the machine is capable of breaking the
material without levering.
◆
Never break off too large pieces. Adjust the
breaking distance (A) so that the working tool
does not become stuck.
Breaking
◆
Never use the machine as a lever, the material
must be broken by impact energy.
◆
If the tool becomes stuck, never try to lift it by
pulling on the top of the fuel tank.
◆
Check that the handle bar can move freely (up
and down) without binding.
◆
Let the machine do the work. Never press too
hard. The vibration absorbing handles must
never be forced all the way to the bottom.
◆
The feed force must be adjusted so that the
handles are pressed 'half way down'. This
position provides the best vibration damping
and the best breaking force.
◆
Avoid working in extremely hard material such
as granite or reinforcing iron, since such
materials can cause strong vibrations.
◆
Never block or cover the cooling air inlet (A)
during operation.
◆
Avoid idling; operation without a working tool
and operation with the machine lifted.
◆
Release the throttle lever when the machine is
lifted.
