Guidelines for speed adjustment

Low speeds for:

• workpieces with large diameters

• hard workpieces with large diameters

• long, unbalanced workpieces

• glued pieces of wood

Speed adjustment (Fig. 7)

• The speed adjustment must always be carried out

with the machine switched on.

• By pulling, the lever disengages and can be turned

to the desired level, in which the lever is to be en-

gaged again.

Note: before clamping a new workpiece, set the diam-

eter of the workpiece and, accordingly, set the speed

according to the speed diagram. For unbalanced or

very large workpieces, select at least 1 level smaller.

Driver, Fig. 1.2, A

The driver is used exclusively for work between both

centers.

Face plate, gure 1.1

The face plate is used with at larger tools.

Change of the clamping tools

• Loosen grub screw on the shaft of the clamping tool.

• Retain spindle with mandrel, release the clamping

tool with the hexagonal spanner.

Headstock, Fig. 9

• The headstock can be swivelled after releasing the

clamping handle and pulling the locking bolt up to

180° (engagement positions 60°/90°/135°/180°).

• The headstock must be clamped again in each posi-

tion.

• The headstock is to be adjusted in the released po-

sition on the drilling bed in order to attach the tool

rest from the left onto the tailstock.

• These positions enable you to process tools with

larger diameters.

Tailstock

• Once the eccentric clamp has been loosened, the

tailstock can be moved over the entire length of the

bed and can be secured at any distance from the

headstock.

• To insert a workpiece between the centers, loosen

the binder, turn the sleeve approx. 20 mm outward

and clamp.

• Slide the tailstock to the workpiece and place the

tailstock center into the sunken point in the center

of the workpiece.

• Screw out the tailstock sleeve until the tailstock

center rests securely in the wood. Retighten the

binder.

• Turn the workpiece to see if it rests securely be-

tween the two centers and can be rotated freely.

Tailstock center replacement, Fig. 1.1, 4

• Loosen the binder (5).

• Turn tailstock spindle sleeve totally backwards until

the tip can be removed.

Tool holder, Fig. 9, 10

• 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.

• If the headstock is swivelled, then the tool rest with

the extension is to be used (Fig. 11).

• Therefore it is inserted from the left of the headstock

so that larger discs can be processed.

Use of wood turning tools, Fig. 11

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 ssures 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 rst 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.
