DANGER

Risk of accidents, injuries. If one point of the safety check is not fulfilled, the appliance must not be taken into operation, but must be repaired.

The following safety tests must be conducted prior to each operation:

6.6.1 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

6.7 Daily maintenance tasks

Carry out the daily maintenance tasks (see section "Maintenance and Care").

7 Operation

△DANGER

Danger of crushing. Make sure that no persons are present 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 pressure 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 measures in the Chapter "Malfunctions".

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 direction 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.

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!

1 Brake pedal
2 Locking mechanism of brake pedal (emergency brake)
3 Stop work speed
4 Accelerator pedal, forwards
5 Accelerator pedal, reverse

7.1.1 Release parking brake

Press the brake pedal all the way.
Turn the lock toward the rear.
Release the brake pedal.

7.1.2 Start the engine

Remove your foot from the accelerator pedal.
Set engine speed to MIN position.
Press the brake pedal all the way down.

The indicator lamp for the emergency brake must be illuminated.

With low exterior temperatures, turn the ignition key to pre-heating setting for about 3 seconds.
Turn the ignition key to "Start engine" and hold it there until the engine starts up.
Release the ignition key. The ignition key turns to position "1", engine on.
Release the brake pedal.

CAUTION

Risk of damage by overheating of the power transmission and the brake. Do not drive appliance while brake is activated.

After a cold start, let the appliance warm up while the engine speed is set to MIN, so that the hydraulic oil can reach operating temperature.

The pre-heating time depends on the ambient temperature and can be read from the diagram below.

7.1.3 Driving

ATTENTION

The speed is reduced when you release the gas pedal; a property that is different to passenger cars.

In transport mode, the speed reduction due to braking when you let go of the gas pedal is lower than in work mode.

Raise the working machine.
Raise the suction opening and the side-brushes (for sweepers).
Set engine speed to ECO.
Press accelerator pedal down slowly.
Control the driving direction with the steering wheel.

7.1.4 Stop

Release the accelerator pedal or drive backwards for a moment, the machine brakes automatically and stops.

Only use the brake pedal if the appliance does not stop in spite of applying the above measures.

CAUTION

Risk of damage to the drive system. Use the brake only in emergencies and as an emergency brake while the appliance is not moving, not as an operational brake.

7.1.5 Driving over obstacles

WARNING

Risk of damage! Raise the side-brushes and the suction opening before overtaking hurdles.

Obstacles up to 150 mm in height:

Bypass the obstacles slowly and carefully at an angle of 45^ .
Obstacles more than 150~mm in height:
Only drive over these obstacles using a suitable ramp.

Warning

Risk of damage! Ensure that the vehicle does not get stuck up.

7.2 Turn off device

Raise the work machine.
Stop the machine.
Switch off PTO.
Set engine speed to MIN position.
Let the engine idle for 1 to 2 minutes.
Turn ignition key to "STOP" and remove it.
