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 fasten.
Breaking
◆
Never use the machine as a lever, the material
must be broken by impact energy.
◆
If the tool fastens, 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 handle must
never be forced all the way to the bottom.
◆
The feed force must be adjusted so that the
handle is pressed 'half way down'. This position
