5.1 Delivery
After delivery, check the lathe for visible transport da-
mage. If you discover any damage to the lathe, report it
immediately to the transport company or dealer.
Transport
Improper transport is accident-prone and can cause da-
mage or malfunctions for which we do not grant any liabi-
lity or guarantee.
Transport the scope of delivery secured against shifting
or tilting with a sufficiently dimensioned industrial truck to
the installation site.
General risks during internal transport
Devices may only be transported by authorized and qua-
lified persons. Act responsibly during transport and al-
ways consider the consequences. Refrain from daring
and risky actions.
Gradients and descents (e.g. driveways, ramps and the
like) are particularly dangerous. If such passages are
unavoidable, special caution is required.
Before starting the transport check the transport route for
possible danger points, unevenness and disturban-ces
as well as for sufficient strength and load capacity.
Danger points, unevenness and disturbance points must
be inspected before transport. The removal of danger
spots, disturbances and unevenness at the time of trans-
port by other employees leads to considerable dangers.
Careful planning of internal transport is therefore essen-
tial.
Transport with a forklift/lift truck:
For shipping, the device packed in a wooden box is deli-
vered on a pallet so that it can be transported with a
forklift truck or pallet truck.
5.2 Packaging
All of the machine‘s packaging materials and packing
aids are suitable for recycling and must always be dispo-
sed of using material-based recycling systems.
Packaging materials made of cardboard must be shred-
ded and disposed of as part of waste paper recycling.
The foils are made of polyethylene (PE), padding is
made of polystyrene (PS). Dispose of these substances
at a recycling centre or hand them over to the relevant
waste disposal company.
5.3 Storage
Let the lathe cool down completely. Storage the thoro-
ughly cleaned lathe in a dry, clean and frost-free environ-
ment.
Environmental temperature range: -25 °C to +55 °C.
WARNING!
Severe or fatal injuries may occur if parts of the
machine tumble or fall down from the forklift
truck, pallet truck or from the transport vehicle.
Follow the instructions and information on the trans-
port box.
Note the total weight of the machine. The weight of
the machine is indicated in the "Technical data" of the
machine. When the machine is unpacked, the weight
of the machine can also be read on the rating plate.
Only use transport devices and load suspension gear
that can hold the total weight of the machine.
WARNING!
The use of unstable lifting and load suspension
equipment that might break under load can cause
severe injuries or even death. Check that the lifting
and load suspension gear has sufficient load-bea-
ring capacity and that it is in perfect condition.
Observe the accident prevention regulations issued
by your Employers Liability Insurance Association or
other competent supervisory authority, responsible
for your company.
Fasten the loads properly.
WARNING: DANGER OF TIPPING
The device may be lifted unsecured by a maximum
of 2cm.
Employees must be outside the danger zone, the
reach of loads.
Warn employees and, if necessary, advise employ-
ees of the hazard.

Operation
9.1 Speed adjustment
Change the speed only when the motor is running!
To change the speed, the setting lever must be tightened
slightly to release it from its locked position. The desired
speed can be read on the digital display. Make sure that
the setting lever clicks into place again after adjustment.
The speed depends on the following factors:
- Type and nature of woods
- Glued woods
- Dimensions, such as diameter and length of the
workpiece
- Workpieces with large unbalance
- Dry or seasoned woods
- Lathing tools
- Lathe technology
Select a low speed for:
- Large diameter workpieces
- Glued workpieces
- Long workpieces
- Unbalanced workpieces
- Hard workpieces
9.2 Handling the clamping tools
Fig. 10: Handling the clamping tools
Mounting the face plate
Screw the face plate hand-tight onto the main spindle. In-
sert the rod (Pos.1, Fig. 10) into the compatible hole in
the faceplate and hold the main spindle in place using
the open-end wrench (Pos. 2, Fig. 10). Tighten the face
plate firmly to avoid loosening during operation.
Replacement of the face driver
Insert the face drivers manually into the main spindle. To
loosen it again, insert the rod (Pos.1, Fig. 9) at the back
of the main spindle and carefully knock out the face
driver. Hold it firmly to prevent it from falling down and
getting damaged.
Use the face driver only for work "between lace".
Replacing the travelling tailstock centre
Fig. 11: Replacing the travelling tailstock centre
Release the clamping lever for the spindle clamping
(Pos. 1, Fig. 11). Turn the spindle on the handwheel (
Pos. 2, Fig. 11) completely backwards to remove the tail-
stock centre (Pos. 3, Fig. 11).
9.3 Adjustment of the spindle head
Release the spindle head clamp and pull the locking bolt.
Swivel the spindle head to the desired angle. The pos-
sible locking positions are 60°, 90°, 120° and 180°. As
soon as the spindle head is in the correct position, it
must be clamped again.
CAUTION!
Danger of crushing!
Improper work on the machine may result in injury to
the upper limbs
ATTENTION!
Before starting up, check the electrical connection,
cables and contacts.
Use hearing protection!
Wear safety boots!
Wear protective clothes!
Use eye protection!
ATTENTION!
Do not turn the spindle head more than 180° clock-
wise. Damage to the power cable may result.

Fig. 12: Adjustment of the spindle head
Step 1: Do not turn the spindle head counterclockwise
when it is in this position (Pos. 1, Fig.12).
Step 2: Do not turn the spindle head clockwise when it is
in this position (Pos. 2, Fig.12).
With the lathe DB 1100, you also have the option of mo-
ving the spindle head on the machine bed after releasing
the spindle head clamp (Figure 13).
Fig. 13: Move the spindle head.
9.4 Adjustment of the tailstock
Fig. 14: Adjustment of the tailstock
After releasing the tailstock clamping lever (Pos. 1, Fig.
14), the tailstock can be moved on the machine bed as
required.
To clamp a long workpiece between centres, clamp the
tailstock to the clamping lever (pos. 1, Fig. 14). Turn the
tailstock spindle on the handwheel out until the travelling
centering point is pressed sufficiently deep into the work-
piece to be machined. This should protrude approx. 20
mm from the tailstock. Clamp the spindle to the lever
(Pos. 3, Fig. 14). Check by hand whether the workpiece
is firmly seated.
9.5 Adjusting the tool rest
Fig. 15: Adjusting the tool rest
Use the tool rest for safe guidance of the lathe tool and
as a support for the hand. A distance of approx. 1-3 mm
must be set between the workpiece and the tool rest. Ad-
just the tool rest approx. 3 mm below the axis of rotation.
Thinner workpieces can also be worked without an ex-
tension arm (Pos.1, Fig.15). Insert the tool rest (Pos.2,
Fig.15) directly into the traverse slide (Pos. 3, Fig. 15).
By releasing the clamping lever (Pos.4, Fig.15), the travel
carriage can be moved on the machine bed as required.
When machining larger workpieces, the tool rest with ex-
tension arm must be mounted to the left of the headstock
(Figure 16).
Fig. 16: Tool rest mounted left
Finally tighten all clamping levers.
Turn the workpiece several times by hand to check the
settings and avoid collisions.

Care, maintenance and repair
Choice of materials
Defective wood tends to splinter and becomes a risk for
user and machine.
Work pieces made of glued wood should only be proces-
sed by an experienced craftsman. Turning these woods
requires careful gluing without weak points, as the work-
piece can explode due to the centrifugal force generated.
The user should master the basic knowledge of turning
with solid material.
Material preparation
For turning of the log wood, the material must first be cut
to a square shape.
For turning crosswise wood, the material must also be
cut raw. You can, for example, saw out the crossbar raw
with a band saw. An octagonal shape is suitable to avoid
vibrations.
Center workpiece
The centering of the prepared workpieces is an import-
ant operation before they are inserted into the machine.
Centering means measuring the center of the workpiece,
marking it with center punches and making a recess of
1.5 to 2 mm in diameter in the center. If the workpiece is
not centered exactly, the unbalance will cause excessive
vibrations. This can result in the workpiece being
ejected. A clean concentric run can only be achieved by
exact centering of the workpiece.
During turning
The unmachined part must be machined at low speed.
After pre-turning, i.e. when the basic shape of the work-
piece has been achieved and uniform concentricity has
been achieved, the speed can be increased. The rotating
center of the center punch must be readjusted by means
of the handwheel when the motor is switched off. The
centre poin of the grain must sit firmly in the wood. Turn
the workpiece by hand to check the tight fit between the
tips.
Technical literature
The specialized trade offers literature about turning. It is
a great help for beginners and experts and also contains
many suggestions for processing.
10 Care, maintenance and repair
10.1Care by cleaning
