Make the first pass for pressing a bituminous layer without vibration. Make the last pass for smoothing the
bituminous layer without vibration.
1. Set the throttle control lever to the maximum operation position. Do not adjust the speed of the machine
with the throttle control lever but with the drive lever.
2. Select the required vibration (front drum, rear drum or both).
Refer to: Console Switches (Page 20).
3. Select the automatic vibration if required.
4. Use the drive lever to move the machine in the forward or backward direction.
5. Put the drive lever into the neutral position in order to stop the machine.
6. Press the vibration switch to turn on vibration. Do not vibrate when the machine is stationary. Only switch
the vibration on when the machine is driving. Press the vibration switch again to switch off the vibration
before the machine has stopped.
7. Do not make any further vibration passes once the optimum compaction of the filling material has been
achieved as this can impair the result of the vibration.
8. Use a recognised method of measurement to test the compaction achieved.
The recommended driving speed with vibration is 3 –4 km/h ( 1.9 –2.5 mph)
