6. Operation
6.1 On/Off switch (1)
To switch on the equipment set the On/Off switch
(1) to position I.
Move the On/Off switch (1) to position 0 to switch
off the equipment.
Important!
When you are not working with the fl exible shaft
(12), it is not allowed to be mounted on the
equipment because it could then fl y around out
of control.
After switching on, wait for the equipment to reach
its maximum speed of rotation. Only then should
you begin with the grinding.
6.2. Speed selector (Fig. 1)
The required speed can be set with the speed
control (11).
6.2.1 Speed of the fl exible shaft
The correct speed depends on the tool used and
the type of material being processed.
6.3. Information on speed settings
•
Small cutters/grinding pins: High speed
•
Large cutters/grinding pins: Low speed
6.4. Work practice
•
Exert only moderate pressure on the work-
piece so that it can be machined at constant
speed.
•
Instead of accelerating your work, high pres-
sure will cause the drive unit to slow down
and even stop, thus overloading the motor.
•
For your own safety, it is essential to secure
small workpieces with a screw clamp or vise.
•
Precision work/engraving: Hold the handle of
the flexible shaft (12) the same way as you
would hold a pen.
•
Rough work: Hold the handle of the flexible
shaft (12) the same way as you would hold
the shaft of a hammer.
6.5 Grinding
•
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 grin-
ding wheel make contact.
•
Move the workpiece slightly back and forth to
produce an optimal grinding result. This way

the grinding wheel (5) will be evenly worn. Al-
low 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.
6.6 Polishing
•
Apply a thin coating of polishing paste to the
grinding surface of the polishing wheel (6)
(Fig. 18/ Item 3).
•
Press on the workpiece in the polishing direc-
tion and move back and forth from left to right
in a pendulum action.
•
Always carry out polishing work in the direc-
tion of rotation of the polishing wheel (6).
Important!
Polishing in the opposite direction to the direction
of rotation of the polishing wheels (6) can cause
damage to the polishing wheels, which in turn can
result in injuries.
