Tailstock center replacement, Fig. 1.1, 4
• Turn tailstock spindle sleeve totally backwards until
the tip can be removed.
Tool holder, Fig. 1.1, 3
• The tool holder both insures safe use of wood turn-
ing tools and at the same time serves as a support
for the hand.
The height of the tool holder can be adjusted once
the binder has been loosened. To turn further, pull in
the direction indicated by the arrow.
• Place the tool holder at a distance of 1 – 3 mm from
the workpiece. Check the adjustment in addition to
rotating the workpiece by hand.
• Set the tool holder ca. 3 mm above the axis of the
workpiece.
Check the adjustment once again by rotating the
workpiece by hand.
• Once the eccentric clamp has been loosened,
the holder console can be moved along the entire
length of the bed and in the direction perpendicular
to the workpiece. Furthermore, the holder console
can be tilted over approx. 45º to either side.
• To work with a plane surface, turn the tool holder
90º and place up against the surface to be worked.
Depending on the wood turning tool, place the tool
holder up to 6 mm underneath the axis of the work-
piece.

Examples of how to use the tools when working with
the most frequent forms. Once the machine has been
plugged in, it is ready to be used. Observe the operat-
ing instructions in „Electrical connection“.
Operations
A perfect and sharp wood turner tool is a precon-
dition for professional wood-turning.
Selection of materials
• Wood to be turned must be of good quality and with-
out imperfections such as fissures against the grain,
a marred surface, or knots. Faulty wood tends to
split and becomes a risk for both the operator and
the machine.
• Workpieces that have been glued together should
only be processed by experienced craftsmen. Be-
cause the workpiece can explode as a result of
developing centrifugal force, turning such wood de-
mands careful gluing without weak points.
Note: Beginners should first master fundamental skills
by working exclusively with solid material.
Preparation of the materials
• To turn long pieces of wood, the material must be
cut into a square form beforehand.
• To turn a cross-arm, the material must be cut to size
in its natural state as well. Saw out the rough form
with a band saw. An octagonal form is recommend-
ed for the material so that vibrations are reduced.
Centering of the workpiece, Fig. 05
Centering the prepared workpiece is an important
operation to be performed before placing it into the
machine.
Centering consists of measuring the middle point of
the workpiece and marking it with a center punch.
Make a depression of 1.5 to 2 mm in the middle point.
If the workpiece has not been centered exactly, strong
vibrations will develop as a result of the imbalance. It
is possible that the workpiece could be hurled outward
as a result.
NOTE: Exact centering of the workpiece produces
smooth concentricity.
While working with the turner
• Work with a rough workpiece should be conducted
at low speeds.
• Only after the wood has been pre-turned (the pre-
turning operation is complete once the basic form of
the workpiece as well as an even concentricity have
been achieved) can the speed be raised.
TURN OFF AND UNPLUG THE MOTOR FIRST
• The live center must be readjusted from time to time
with the hand wheel. This operation only should be
performed when the motor has been turned off.
The tailstock center should rest firmly in the wood.
• Turn the workpiece by hand to check if it rests se-
cured.
Marking of the workpiece
Sometimes the workpiece has to be taken out before
it has been completed. It is advantageous to mark the
workpiece and the driver with a pencil first.
When placing the workpiece back in the machine,
match the marks on the workpiece and the driver.
Specialized literature
Specialized shops offer appropriate specialized litera-
ture about wood turning. They can be a great help for
beginners in their work as well as a source of ideas
for experts.

Electrical connection
The installed electric motor is completely wired ready
for operation.
The customer’s connection to the power supply sys-
tem, and any extension cables that may be used, must
conform with local regulations.
Important remark:
The motor is automatically switched off in the event of
an overload. The motor can be switched on again after
a cooling down period that can vary.
Defective electrical connection cables
Electrical connection cables often suffer insulation
damage.
Possible causes are:
• Pinch points when connection cables are run
through window or door gaps.
• Kinks resulting from incorrect attachment or laying
of the connection cable.
• Cuts resulting from running over the connecting ca-
ble.
• Insulation damage resulting from forcefully pulling
out of the wall socket.
• Cracks through aging of insulation.
