Clamping the cutting tool (Fig. 9)

Caution!

Insert the cutting tool as far as possible when clamping. Along

projection causes vibrations, inaccuracies and apoor surface.

Cuttingtools with across section of up to 6x6mmcan be

clampedinthe tool holder.

1. Turn out both fastening screws 1(Fig. 9) until the selected

cutting tool 2fits into the holding fixture

2. Insert the tool in the tool holder groove and clamp tight with

the screws 1. Caution: Insert the tool as far as possible when

clamping!

3. Move thetip of the tool to the lathe centre of the tailstock and

checkthe height.

It may be necessarytoput, e.g., thin sheets covering the area

underneath the tools in order to compensate the height for dif-

ferent sizes.

The tool holder provides the possibility of clamping two cutting

tools at the same time. This simplifies work, because after ad-

justing the cutting tools between the individual machining stages

for aworkpiece, it is only necessarytoswivel the tool holder in

order to work with the respectively suitable tool.

To do so, simply loosen the Allen screw 4, swivel the tool hold-

er and then retighten the screw 4. Of course it is possible to gen-

erally regulate the angle of the tool to the workpiece in this man-

ner,ifrequired.

Restart protection

Caution!

For safety reasons, the machine is equipped with aso-called

restart protection: In case of brief voltage interruptions during

operation, the machine will not restart for safety reasons.

But in this case, the machine can be started normally with the

On button.

Demand-actuated rotational speed

The spindle speed needs to be adjusted according to workpiece

material and diameter: On the one hand, the cutting speed de-

creases with smaller turning radii, which needs to be compen-

sated by ahigher rotational speed; on the other hand, the choice

of the correctrotational speed is also dependent to ahigh de-

gree on the material to be machined. The task here is to find the

right compromise.

For that reason, we have equipped our lathes with an electronic

speed control as well as atwo-stage belt drive.

This covers the rotational speed range from 800 up to 5000 rev-

olutions.

Setting the spindle speeds (Fig. 10)

Shifting the drive belt

Caution!

Youabsolutely must disconnect the mains plug before working

in the gear case. Risk of injury!

1. Loosen theknurled screw 1atthe headstock and swing open

thecover 2.

2. Loosen the Allen screw from the belt tightener 3.

3. Preselect the corresponding speed by shifting the drive belt

4. Please make sure the drive belt is seated correctly on the

belt pulley!

4. Lightly press the tension jack 3inthe long slot 5against the

belt drive and then retighten the Allen screw.Ensure suitable

belt tension. Toomuch tension increases wear to the belt and

bearings and greatly slows down the motor.

5. Before starting work, close the gear case and retighten the

knurled screw 1.

Electronic speed control

In addition to the selection of gearbox stages by means of shift-

ing the drive belt, your machine also offers you the possibility

to electronically adapt the rotational speed to the respective con-

ditions.

1. Turn the rotational speed regulating knob Item 6(Fig. 10) to

the left or right to set the rotational speed during operation.

Working with the machine (Fig. 11):

Caution!

Always work within the intended performance range!Avoid

spindle blockages caused by overloading. In the event of the

spindle blocking during operation, please switch off the machine

immediately and configure the feed and infeed for further ma-

chining to avoid overloading of the machine.

Caution!

Always work within the intended performance range! Avoid spin-

dle blockages caused by overloading. In the event of the spin-

dle blocking during operation, please switch off the machine im-

mediately and configure the feed and infeed for further machin-

ing to avoid overloading of the machine.

Caution!

Before inserting the mains plug, please check if the information

on the rating plate matches the local conditions of your mains

supply.Ifthey do not match, then damage or hazards during

work could be result!

Caution!

Always wear hearing protection and protective goggles while

working!
