• Ensure that the desired speed A4 is permissible for the tool and
toolholder used.
1. Remove retention pin A2.
2. Turn excenter A5 clockwise until it reaches the limit stop. Re-
lease retention pin A2. All speeds must be visible in this position.
3. Move excenter A5 axially until the correct.
4. Operating speed A4 is positioned in front of the speed
indicator A3.
5. Turn excenter A5 all the way to the left.
6. Retention pin A2 must click audibly into place.
7. Ensure that the correct operating speed is positioned directly
and centrally in front of the speed indicator A3. If the retention
pin does not click into place, or the selected speed is not dis-
played in the center, the procedure must be repeated from Step
1 .
• Attention: In case the machine is operated in one gear position
only - one must at least once a week switch through all positions
for a brief period in order to redistribute the grease for long gear
service life. (run without flex.Shaft and handpiece)
3. Connect the flexible shaft

1. Insert pin in retention hole.
2. Slightly withdraw threaded coupling B1 from casing coupler B2.
3. Insert second pin through transverse hole in threaded coupling
B1 and
4. Fasten tightly onto the motor shaft A6.
5. Remove pins.
6. Insert casing coupler B2 completely into excenter hole A5.
7. Depress spring-loaded pin B3 and completely insert casing
coupler B2.
8. Spring-loaded pin B3 must click audibly into place in the retenti-
on hole. Ensure that spring-loaded pin B3 has locked firmly into
place. If necessary, move/rotate casing coupler B2 until spring-
loaded pin B3 clicks into place.

1. Insert casing coupler B8 into tool connection.
2. Depress spring-loaded pin B7 and completely insert casing
coupler B8.
3. Spring-loaded pin B7 must click audibly into place in retention
hole C1. Ensure that spring-loaded pin B7 has locked firmly into
place. If necessary, move/rotate casing coupler B8 until spring-
loaded pin B7 clicks into place.

The connection of toolholders corresponds to the procedure de-
scribed in Item 3.3.
Note: Toolholders WI10, BSG10 and FSM can be rotated on the
casing coupler for easier handling.
3. Start-up with SAK safety clutch (deadman switch)

See Fig. D
Only with machine in OFF position !
1. Depress locking pin C3.
2. Completely depress safety lever C2. If necessary, move to star-
ting position by turning the working spindle D1 and repeatedly
depressing safety lever C2.
• Attention: The powerfull machine develops a heavy torque when
switched-on. Thus secure yourself in a rigid position and hold
on to the handpiece.
• Switch on drive motor A1 (Motor starts softly.)
• Switch off by releasing lever C2. Torque transmission to the
toolholder is interrupted. Locking pin C3 protects from automatic
start-up.
• Switch machine off in order to return safety lever C2 to starting
position.
