Maintenance
• Store machine in a dry, clean place.
• Cooling air ports must be kept free of obstructions.
• Unplug before performing any maintenance work.
• Change of carbon brushes and wear/tear parts: 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.

NA7x2000 DIN10/G22, permissible operating speed 28'000 RPM
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.
• 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).
3.0 Start-up procedures
3.1 Set the operating speed
Attention: General
Do not change pre-selected speed while tool is running and has wor-
king tools mounted. Only change speed when machine is switched off.
Unplug power supply.
Typ Minifix 9R see Fig. A
• Ensure that the desired speed A2 is permissible for the tool and tool-
holder used.
• Speed indicator label A3 shows all 6 positions.
• Turn speed selector A2 to required speed position
Speed selector position 6 = 9 ' 000 RPM
5 = 8 ' 000 RPM
4 = 7 ' 000 RPM
3 = 6 ' 000 RPM
2 = 5 ' 000 RPM
1 = 4 ' 000 RPM
3.2 Connect the flexible shaft to the motor dee Figs. A + B
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 A4.
5. Remove pins.
6. Insert casing coupler B2 completely into motor connection 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.
3.3 Connect toolholders (accessory) 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, WI7 with 45° and WIG7 can be rotated on the
casing coupler B8 for easier handling.
3.4 Operation conditions and instructions for Minifix 9R
This tool is equipped with an electronic variable speed tachometer selec-
tor and an overload cut-out switch, which operates as follows:
1. Soft start
2. With increased work pressure more current is drawn , which virtually
holds speed at a constant rpm.
3. If the motor is overloaded, the electronic cuts off the power. In this
event switch at once to OFF position, restart right away to assure
cooling effect in no load mode. Repeated automatic cut off indicates,
tool is being overloaded.
4. Caution: Electrical surges and high frequency interference may cause
RPM fluctuations up to 30% which will disappear as soon as power
source conditions stabilize. Due to electromagnetic interference at a
lower speed range the drive motor may shut-off prematurly. In this
case, activate on/off switch and restart.
Note:
Never use Minifix 9R in conjunction with another speed control device
(foot pedal or table mount). Otherwise built-in electronic variable speed
control can no longer function as intented.
