Restarting a warm machine
If a hot engine stops after a short while or does not
start at all, use the following restart procedure:
1. Check that the choke is open (in position
WORK).
2. Pull the starter handle.
3. If the machine still does not start follow the
procedure for "Cold start" or see the section
"Troubleshooting".
Stopping
1. Stop the machine by sliding the stop button on
the left handle forward.
Operating
Starting a cut
◆
Stand in a stable position with your feet well
away from the working tool.
◆
Press the machine against the working surface
before starting. The feed force should be
adjusted so that the handle is pressed at least
'half way down'. This position provides the best
vibration damping and the best breaking force.
◆
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 leverage.
◆
Never break off too large pieces. Adjust the
breaking distance (A) so that the working tool
does not fasten.
A
Breaking
◆
Never use the machine as a lever, the material
should be broken by impact energy.
◆
Let the machine do the work. Never press too
hard. The vibration absorbing handle should
never be forced all the way to the bottom.
◆
Release the throttle lever when the machine is
lifted.
