INSTRUMENTS AND CONTROLS

SERVICE BRAKE FILTER WARNING LIGHT

The light will come on when oil flow through the filter is restricted. It means that the filter element is
contaminated and must be replaced. The light may come on when starting cold machine and
should go off when the oil is warmed in the system.

3. TRANSMISSION FILTER WARNING LIGHT
The light will come on when oil flow through the filter is restricted. It means that the filter element is
contaminated and must be replaced. The light may come on when starting cold machine and
should go off when the oil is warmed in the system.

4. HYDRAULIC FILTER WARNING LIGHT
The light will come on when oil flow through the filter is restricted. It means that the filter element is
contaminated and must be replaced. The light may come on when starting cold machine and
should go off when the oil is warmed in the system.

5. FUEL LEVEL LIGHT
The light indicates that 60 l of fuel (app. 1 hour of operation) is available for operation and the fuel
tank must be filled.

6. GROUND DRIVEN STEERING WARNING LIGHT
This warning light is not included in standard configuration of the machine. If the machine is
equipped with ground driven system ( that enables steering of the machine at loss of pressure in
steering system) the light will come on when the system is activated. The vehicle must be in motion
to activate the ground driven steering system.

7. PARKING BRAKE WARNING LIGHT
The light will indicate if the parking brake is applied. At the same time a buzzer will sound.

WARNING: Release the parking brake before starting the machine.

8. ENGINE COOLANT TEMPERATURE WARNING LIGHT
The light will indicate when the coolant temperature exceeds allowable limit. If the light comes on,
maneuver the machine to the side and operate the engine at low idle. If the light stays on,
investigate the cause and take corrective action before operating the machine again.

9. SERVICE BRAKE WARNING LIGHT
The light will indicate:

−

drop of pressure in brake cooling system below allowable limit,

−

failure of one of the brake circuits,

−

drop of pressure in brake system below allowable limit,

−

drop of nitrogen pressure in nitrogen accumulators below allowable limit.

Also, a buzzer will come on. Stop the machine immediately and remove the cause of the failure. To
maintain optimum performance nitrogen accumulators must be filled with nitrogen (at gas side).
Nitrogen pressure is 8.78 to 9.84 MPa ( for temperature range 10 to 43

C). Accumulators are

equipped with electrical switches indicating loss of nitrogen pressure below the allowable limit.
Warning light 9 will come on and buzzer will sound when pressure drops below the allowable value.
Starting the machine is followed with rapid oil and nitrogen pressure rise in accumulators and short
period when the light is on might not be noticed by the operator. The signal is supported by an
electronic device and may be cancelled by the representative of Authorized Service upon filling the
accumulators with nitrogen. Indication of nitrogen low pressure in accumulators does not exclude
machine operation, however, it means reduced efficiency or loss of emergency braking with the
engine running.
