5.6 Switching the vibration on and off

WARNING!
Risk of damage!

When compacting with vibration you must check

the effect of nearby buildings and underground

supply lines (gas, water, sewage, electric power), if

necessary stop compaction with vibration.

NOTICE!
Danger of bearing damage!

Do not activate the vibration on hard (frozen, con-

crete) ground.

NOTICE!

During operation the throttle lever always remains

in "MAX" position. Control the travel speed with the

travel lever.

Switch the vibration on only at maximum engine

speed.

Vibration at standstill causes transverse ruts,

therefore:

switch the vibration on only after shifting the travel lever to

the desired travel direction.

Switch the vibration off before stopping the machine.

Set the throttle lever

Fig. 55 to position "MAX".
