Accident risk
Be sure to check the parking brake before using the device.
Never use the device if the parking brake is not working.
DANGER
No braking effect during operation
If the device no longer has any braking effect during oper-
ation, proceed as follows:
If the device does not come to a standstill on a ramp with
a gradient of more than 2% when you release the acceler-
ator pedal, for safety reasons you may only set the safety
switch to position "0" if you have checked the correct me-
chanical function of the parking brake before starting up
the device.
After reaching a standstill, put the device out of operation
and call Customer Service.
Observe the maintenance instructions for brakes.
DANGER
Careless driving
Danger of tipping over
Only drive on gradients in the travel direction up to a max-
imum of 15% (RI variant) and 10% (RI Combo variant).
Gradients transverse to the travel direction up to a maxi-
mum of 15%.
Do not turn on gradients.
Drive slowly in corners and on wet ground.
Only drive the device on stable ground.
Pivoting sweeping mechanism on the Combo variant
Increased risk of accidents
Be especially careful when reversing.
Take the pivoting of the sweeping mechanism into account
when steering.
Note

eration. This allows very dull spots to be polished by mov-
ing back and forth several times.
