2.2.5 Driving with vibration
When the vibration system is switched on, the
drum will vibrate according to the speed of the
vibrator. This hammering will increase the com-
pacting force of the machine several times
over.
Vibration may only used at maximum diesel
engine speed and can be operated as single or
double vibration.
An elastic suspension of the drums prevents
the transfer of vibration oscillations to the ma-
chine frame.
If intensive compacting with few transitions
shall be obtained during earth-moving work,
the machine must roll over the material to be
compacted with low driving speed and excite
and compact it with the corresponding frequen-
cy.
Only when the driver is on his/her seat and
the driving lever is in centre position, will
driving operation be possible.
Do not switch off the key switch (310) dur-
ing travel (key position 0).

Danger of collapse!
Vibration must not be used in the immedi-
ate vicinity of buildings or bridges as these
can be damaged or destroyed by the vi-
bration oscillation.
Danger of explosion!
Prior to switching on the vibration function,
it must be ensured that lines laid in the un-
derground (gas, water, sewage, electricity
lines) cannot be damaged or destroyed by
the vibration oscillations.
Danger of falling!
The oscillating drum decreases road adhe-
sion. When driving on hard surfaces, and
in particular when driving in transversal di-
rection to slopes, lateral stability is de-
creased.
