Assemble the flexible shaft
1. Insert the shaft core completely to the protection hose and rotate in the process.
Rotating the shaft core spreads the special lubricant.
2. Insert the shaft core into the shaft core adapter of the vibrator head.
3. Apply pipe thread seal (accessory) to the thread of the coupling.
4. Screw the coupling onto the flexible shaft and tighten with a large pipe wrench or special wrench
(accessory).
5. Check the shaft core for smooth and effortless movement while rotating with a special wrench
(accessory).
11.3.4 Vibrator head
Check wear dimensions of the vibrator head
The wear dimensions are:
Minimum diameter of vibrator head (H-vibrator head).
Minimum wrench size of the square (HA-vibrator head).
The wear is highest at the end of the vibrator head.
If a wear dimension is reached at one point, have the tube bottom exchanged by your Wacker Neuson
contact partner.
NOTICE
If the shaft core is new, you have to run in the drive motor for about 5 minutes with a
connected flexible shaft (possibly also with the vibrator head).
