Operations
A perfect and sharp wood turner tool is a precondition for pro-
fessional wood-turning.
Selection of materials
-
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.
workpiece can explode as a result of developing cen-
trifugal force, turning such wood demands careful gluing
without weak points.
Note: working exclusively with solid material.
Preparation of the materials
into a square form beforehand.
its natural state as well. Saw out the rough form with a
band saw. An octagonal form is recommended for the
material so that vibrations are reduced.
Centering of the workpiece (Fig. 06)
Centering the prepared workpiece is an important opera-
tion 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 vi-
brations 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
speeds.

ing 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
with the hand wheel. This operation only should be per-
formed when the motor has been turned off.
The tailstock center should rest firmly in the wood.
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 literature
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 system,
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 cool-
ing down period that can vary.
Defective electrical connection cables
Electrical connection cables often suffer insulation dam-
age.
Possible causes are:
window or door gaps.
the connection cable.
of the wall socket.
Such defective electrical connection cables must not be
used as the insulation damage makes them extremely haz-
ardous.
Check electrical connection cables regularly for damage.
Make sure the cable is disconnected from the mains when
checking.
Electrical connection cables must comply with the regula-
tions applicable in your country.
Single-phase motor

Only a qualified electrician is permitted to connect the ma-
