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
GB
grease to core B5.
• New shafts or newly greased shafts require running-in.
• 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
W
not click into place, or the selected speed is not displayed in
W
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.

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.

See Fig. C
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.
Note: Toolholders WI7 with 45°, WI7 and WIG7 can be rotated
on the casing coupler for easier handling.

• 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.
