Speed of the flexible shaft
The correct speed depends on the tool used and the type of material being processed.

Information on speed settings

• Small cutters/grinding pins: High speed
• Large cutters/grinding pins: Low speed

Proper work practices

1. Exert only moderate pressure on the workpiece so that it can be machined at constant speed.
2. Instead of accelerating your work, high pressure will cause the drive unit to slow down and even stop, thus overloading the motor.
3. For your own safety, it is essential to secure small workpieces with a screw clamp or vise. :
   • Precision work/engraving: hold the drive unit like a pen.
   • Rough work: hold the drive unit like the handle of a hammer.

Grinding

1. Place the workpiece onto the workpiece support (8) and slowly guide the workpiece towards the grinding wheel (5) at the desired angle to the point where workpiece and grinding wheel make contact.
2. Move the workpiece slightly back and forth to produce an optimal grinding result. This way the grinding wheel (5) will be evenly worn. Allow the workpiece to cool down occasionally.
   Important! If the grinding wheel becomes jammed during operation, remove the workpiece and wait until the tool reaches its top speed again.

Polishing

1. Apply a thin coating of polishing paste to the grinding surface of the polishing wheel (6) (Fig. 18/ Item 3).
2. Press on the workpiece in the polishing direction and move back and forth from left to right in a pendulum action.
3. Always carry out polishing work in the direction of rotation of the polishing wheel (6).

Important! Polishing in the opposite direction to the direction of rotation of the polishing wheels can cause damage to the polishing wheels, which in turn can result in injuries.

ELECTRICAL CONNECTION

The electrical motor installed is connected and ready for operation. The connection complies with the applicable VDE and DIN provisions. The user’s mains connection as well as the extension cables used must also comply with these regulations. The mains voltage must be 220 – 240 v~.
Extension cables up to 25 m long must have a cross-section of 1.5 mm?. Extension cables over 25 m long must have a cross-section of 2.5 mm?.

Damaged electrical extension cables
The insulation of extension cables is often damaged. This may be caused by the following:

• Pressure points, where extension cables are passed through windows or doors.
• Twist where the extension cable has been improperly fastened or routed.
• Places where the extension cables have been cut due to being driven over.
• Damage to the insulation due to forcible removal of the extension cord from the outlet.
• Cracks due to ageing of the insulation.
  Such damaged electrical extension cables must not be used and are life- threatening due to the insulation damage. Check the electrical extension cables for damage regularly. Ensure that the extension cables are disconnected from electrical power when checking for damage.

Connections and repair work on the electrical equipment may only be carried out by skilled electricians. If the power cord of the device is damaged, it must be replaced by an authorised service center or a similarly qualified person to avoid dangers.
