Note:
Check with your local Electricity
Board or electrician if in doubt whether
your house service connection meets
these requirements.
Position power supply cable in a way
that it does not interfere with the work
and is not damaged.
Protect power supply cable from heat,
aggressive liquids and sharp edges.
Use only rubber-jacketed cable of suf-
ficient lead cross section as exten-
sion cable.
Do not pull on power supply cable to
unplug.
B
Changing the direction of rota-
tion!
Depending on the phase sequence it
is possible that the motor will turn in
the wrong direction. This can lead to
the log being hurled away when
attempting to make a cut. Therefore
the rotational direction must be
checked every time the machine is
connected to a different outlet. With
an incorrect direction of rotation the
phase changer inside the machine's
CEE plug needs to be changed-over:
1. Install machine ready for work
and connect it to the power
mains.
2. Start machine and immediately
turn OFF again.
3
Note:
The humming sound after switch-
ing OFF is caused by the responding
electronic motor brake. It is not a
machine fault!
3. Check the saw blade's direction
of rotation from the left-hand side
of the saw. The saw blade must
rotate clockwise.
4. If the saw blade rotates counter-
clockwise, unplug
cable at the saw.
5. Using a flat-bladed screwdriver,
push the phase changer down
and rotate it by 180.

Caution!
Do not attempt to turn the
phase changer at the contact pins!

6. Operation

Please take note of the following
safety information before operating
the machine!
Also follow the safety instructions
given at the beginning of this manual!
A
Hazard generated by machine
defects!
Before starting any work, check to see
that the following are in proper working
order:
Saw blade (firmly mounted? undam-
aged? sharp? sufficient distance to
other parts?)
Blade guard (undamaged? distance
to saw blade sufficient? does exten-
sion arm return to starting position
automatically?)
Feed rocker (must automatically
return to the starting position)
Power cable, power cable plug and
switch (if damaged, have replaced
by a qualified electrician)
Motor brake (after switching OFF,
no more than 10 seconds post-run-
ning of saw blade)
A
Risk of injury by inhaling wood
dust!
Dust of certain timber species (e.g. oak,
beech, ash) can cause cancer when
inhaled:
Work only out of doors.
When working, take care that as lit-
tle wood dust as possible will get
into the surroundings:
Remove wood dust deposits in the
work area (do not blow away!).
A
Hazard generated by insuffi-
cient personal protection gear!
Wear suitable work clothing, provid-
ing protection against falling logs.
Wear hearing protection.
Wear safety glasses.
the power
Wear dust mask.
Wear non-slip safety shoes.
Take care that no parts of your body
or clothing are caught by rotating
components (do not wear neckties
or loose fitting garments; contain
long hair with a hairnet).
ENGLISH
A
Risk of personal injury and
crushing by moving parts!
Do not operate the machine without
installed guards.
Keep sufficient distance to driven
components when operating the
machine.
Remove small cutoffs, splinters, etc.
near the rotating saw blade only with
the blade at standstill.
Always use the feed rocker to feed
the logs to be cut.
Always hold the feed rocker with
boths hands at its handle.
Assume proper operating position:
at the front of the saw;
in front of the saw;
offset to the line of cut.
After each cut return the feed rocker
completely to its starting position.
A
Hazard generated by pieces of
wood being hurled away!
Always place curved logs on the
feed rocker with the curved side fac-
ing the handle.
Do not jam the log to be cut.
Do not attempt to stop the saw
blade by pushing the workpiece
against its side.
Avoid cutting workpieces or cuts,
which may result in several small
pieces that may be hurled away or
could get stuck.
Always use sharp saw blades.
If in doubt, inspect the logs for for-
eign matter (e.g. nails or screws).
Never cut several logs at the same
time – and also no bundles contain-
ing several individual pieces. Risk of
personal injury if individual pieces
are caught by the saw blade uncon-
trolled.
Avoid making cuts that will cause
the position of the workpiece to
change uncontrolled.
Cut only logs of permissible dimen-
sions (see "Technical Specifica-
tions").
6.1

Cutting

1. Start machine and let the motor
reach full speed.
2. Place a log on the feed rocker.
3. To make the cut, push the feed
rocker (18) with both hands at the
handle towards the saw blade:
exert only so much pressure that
the motor speed does not fall off
push feed rocker all the way
against the stop.
