VIBRATION/DRIVING
Vibration on the drum can be set in two modes,
switching over is made with the switch (28). Turn the
knob to the left for low amplitude/high frequency, to
the right for high amplitude/low frequency.
Amplitude setting High/Low may not be alte-
red while vibration is in action. Wait until
vibration stops before resetting.
Never allow vibration to be on when the roller
is stationary, the surface and the machine
may otherwise be damaged.

Engagement and disengagement of vibration is made
with the changeover switch (23) on the forward/
reverse lever. Always switch off vibration before the
roller comes to a standstill.
Vibration should not be switched off when
changing the direction of travel.
Vibration - Engaging
High/Low amplitude - Setting
SAFETY WHEN DRIVING
Slopes
The tipping angle given here applies to smooth, hard
ground and stationary machine. The steering angle is
zero (machine moving straight forward) and vibration
switched off. Remember that loose ground, steering of
the machine, driving speed and increase in height of
the centre of gravity (eg, accessories) may cause the
machine to topple even on a smaller slope than that
stated here.
Where possible, avoid all driving transver-
sely across a slope. Instead, drive up and
down on sloping ground. The machine
will topple on side slopes greater than 20°
or 36%, to the right or left.
