Centering of the workpiece (Fig. 16)
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
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-turn-
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.
• The live center must be readjusted from time to time
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.
• Turn the workpiece by hand to check if it rests secured.
Marking of the workpiece, figure 17
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.
By means of the spindle locking bolt (E1), you can lock
the spindle.
12 screenings with respectively 30° are possible by mark-
ing out.
Specialized literature
Specialized shops offer appropriate specialized literature
about wood turning. They can be a great help for begin-
ners in their work as well as a source of ideas for experts.
m 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 con-
form 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 dam-
age.
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 cable.
• Insulation damage resulting from forcefully pulling out
of the wall socket.
• Cracks through aging of insulation.

Such defective electrical connection cables must not be
used as the insulation damage makes them extremely
hazardous.
Check electrical connection cables regularly for dam-
age. 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
• The mains voltage must coincide with the voltage spec-
ified on the motor's rating plate.
• Extension cables up to a length of 25 m must have a
cross-section of 1.5 mm , and beyond 25 m at least
2
2.5 mm .

• The connection to the mains must be protected with a
16 A slow-acting fuse.
Only a qualified electrician is permitted to connect the ma-
chine and complete repairs on its electrical equipment.
In the event of enquiries please specify the following data:
• Motor manufacturer
• Type of current of the motor
• Data recorded on the machine's rating plate
• Data recorded on the switch's rating plate
If a motor has to be returned, it must always be dis-
patched with the complete driving unit and switch.

Maintenance

• Overhauls, maintenance work, cleaning, as well as the
elimination of any malfunctions must only be under-
taken after turning off the motor.
• All protective and safety equipment must be reinstalled
immediately upon completion of any repair or mainte-
nance work.
• Clean and lightly oil the spindle thread of the tool hold-
er when changing tools.
• When possible, the tail stock sleeve should be re-
moved by unscrewing it, cleaned and then sprayed
with a dry lubricant. Grease the threaded spindle.
• Check the eccentric clamp of the tailstock as well as
the tool holder and adjust if necessary. In addition,
tighten the hex nut under the bracket.
• Check the drive belt and replace when necessary.
Accessories
Jaw chuck protection Fig. 18
When working with the jaw chuck (accessory), the jaw
chuck protection must be used.
Extension console, Fig. 19
When working on a piece with a max. diameter of up to
500 mm, the extension console which is used must be at-
tached on the frontal side. Thereby, the headstock is re-
moved from the lathe bed, rotated by 180°, attached to
the lathe bed and refastened. The standard tool support
is employed here.
