7 Operation
DANGER
Danger of crushing. Make sure that no persons are pre-
sent near the arm hinges.
Danger of burns, crushing. Only use the appliance if all
casing parts have been attached.
CAUTION
Risk of damage by overheating of the power transmission
and the brake. Only use the brake pedal during travel, if
the appliance does not stop when the accelerator pedal is
released or briefly activated.
Danger of damage due to lack of lubrication. If the oil pres-
sure warning lamp lights up during operation, switch the
engine off immediately and remediate the malfunction.
Risk of damage due to overheated engine or overheated
hydraulic oil. If the warning lamps for engine temperature
or hydraulic oil temperature lights up, set the engine speed
to idle (do not turn the engine off) and perform the meas-
ures in the Chapter "Malfunctions".
Danger of damage to the hydraulic hoses of the sweeping
unit. Do not lower the brush to the ground or the platform
any lower than the position of the wheels (for sweepers).
7.1 Driving
WARNING
The device has a central pendulum joint in order to provide
maximum manoeuvrability.
This enables both vehicle halves to move laterally to the di-
rection of travel independently from one another.
Due to this special feature, the driver does not receive
timely feedback from the rear half of the vehicle.
It is for this reason that the driver has to use the mirrors to
watch the movements of the rear half of the vehicle.
50
 Loosen the clamp screw for steering wheel inclination
adjustment.
 Set the desired inclination of the steering wheel col-
umn.
 Tighten clamping screw.
6.7 Prior to start/safety test
DANGER
Risk of accidents, injuries. If one point of the safety check
is not fullfilled, the appliance must not be taken into opera-
tion, but must be repaired.
The following safety tests must be conducted prior to each
operation:
6.7.1 Safety check
Perform the safety check while the ignition is switched on
(position 1).
 With released parking brake: Release accelerator
pedal, switch off work hydraulics Main PTO - the motor
must not start when turning the ignition key (position 2).
 With actuated brake pedal: Switch on work hydraulics
Main PTO - the motor must not start when turning the
ignition key (position 2).
 With running motor: Switch on work hydraulics Main
PTO, relieve driver seat - the work hydraulics Main PTO
must switch off
6.8 Daily maintenance tasks
Carry out the daily maintenance tasks (see section "Main-
tenance and Care").
Vehicles with articulated steering are much more sensitive
to steering movements than passenger cars – particularly
when taking bends at high speed, on snow, ice and wet/
loose ground as well as during turning manoeuvres on
slopes.
It is therefore extremely difficult to stabilise a vehicle with
articulated steering by countersteering!
