Maintenance
• Store machine in a dry, clean place.
• Cooling air ports must be kept free of obstructions.
• Unplug before performing any maintenance work.
• Change gear grease every 12 months. Your SUHNER Service Centre
can perform this work quickly and efficiently.
• Check connecting cables regularly. Damaged cables must be replaced
under all circumstances.
• Repairs may only be performed by a qualified electrician Accidents
could otherwise occur for the operator.
• Complaints can only be accepted if the machine is returned unopened.

Maintenance
• Store flexible shaft in a dry, clean place.
• If used daily: Re-grease once monthly. Remove core B5 from casing
B4. Remove shaft grease. Lightly apply SUHNER shaft grease to core
B5. Order No. for 1 kg can : 904 832.
• New shafts or newly greased shafts require running-in.
GB
• Clean casing coupler B2 B8 before use. Worn casing couplers lead to
increased vibration and noise. The casing B4 must then be replaced
(see spare parts list).
3. Set the operating speed
1
See Fig. A
• Only change speed when machine is switched off. A1 Wait until gears
are completely motionless. Unplug power supply.
• 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. Release
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 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 the speed indicator A3. If the retention pin does not click
into place, or the selected speed is not displayed 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
W
period in order to redistribute the grease for long gear service life.

See Figs. A + B
1. Insert pin in retention hole.
2. Slightly withdraw threaded coupling B1 from casing coupler B2.
RPM
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 retention 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.
3. Connect the SAK safety clutch

start-up.
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.
3. Connect toolholders
4
See Fig. C
The connection of toolholders corresponds to the procedure described
in Item 3.3.
Note: Toolholders SAM and TAM can be rotated on the casing coupler
for easier handling.
3. Start-up with SAK safety clutch ( deadman switch)

• Attention : The powerfull machine develops a heavy torque when
switched-on. Thus secure yourself in a rigid position and
hold on to the handpiece.
• This machine has a dual start up switch to protect system from
