This warning light comes on when the starting circuit is energized and goes out when the engine exceeds the idling speed; if this warning light remains on even when the engine is running at the normal operating speed, this means that the alternator does not work and the battery is not charged correctly.

HYDRAULIC OIL FILTER CLOGGING WARN-
ING LIGHT
This warning light comes on when the ignition key is turned to po-
sition « » to start the engine at low temperatures and goes out
automatically after approximately 13 seconds (see «3.6.2.2 Start- ing with cold engine or in cold climates»).
RWA07160
This warning light comes on and activates the acoustic alarm with engine at rest when the starting circuit is energized and goes out as soon as the engine lubrication circuit is pressurized.
If this warning light remains on or comes on with the engine run- ning, stop the machine immediately and try to locate the trouble.
RWA07130
RWA31710
This warning light comes on when the engine air filter needs cleaning.
RWA22340
This warning light comes on when the hydraulic circuit filter needs replacing.

It signals that the parking brake has been applied.RWA18440
It comes on when the high speed is selected (see “3.3.3 pos. 12 SPEED INCREASE PUSH BUTTON”).
It comes on when the floating device is connected (see “3.3.3 pos. 13 FLOATING DEVICE SWITCH”).
RWA23300
This warning light comes on intermittently when the lever on the dashboard is operated (see “3.3.3 pos. 8 DIRECTION INDICA- TOR SWITCH”) or when the emergency switch is operated (see “3.3.3 pos. 6 EMERGENCY SWITCH”).
10 - WORKING LIGHT WARNING LIGHT
11 - SAFETY DEVICE FUNCTIONALITY CONTROL
UNIT
It comes on when the working lights are turned on with the switch positioned on the dashboard (see”3.3.3 pos. 5 WORKING LIGHT SWITCH”). RWA07180 RWA31910 C E

RWA22370A
This control unit is positioned on the dashboard and checks the condition of the safety devices installed on the machine.
The signals are shown on the display by the coming on and going out of the warning lights.
The functions are the following:
A - RED WARNING LIGHT
LED off - This means that all the safety devices are on and
therefore all the machine functions are normal (the solenoid valve ensures the lifting of the work equipment and the ma- chine travel).
LED on - This means that at least one safety function is
lacking; in this case the solenoid valve is closed and does not permit the lifting and therefore the use of the work equipment and the machine travel.
B - GREEN WARNING LIGHT
LED on - This means that the operator is correctly seated in
the driving position and that the operator presence sensor is on.
LED off - (With the red warning light coming on at the same
time) This means that the operator is standing or that he is not inside the cab.
IMPORTANT
☞
• The operator presence signal (seat) starts the emergency condition with a delay of 1.5 seconds.
With this solution the operatorís jerks (especially when working on uneven ground) are sensed without signalling repeated emergencies.
RWA22380
C - GREEN WARNING LIGHT
LED on - This means that the safety bars are down and
therefore safety is ensured.
LED off - (With the red warning light coming on at the same
time) This means that the safety bars are not completely down and therefore the work equipment and the travel func- tion cannot be used.

CAUTION
• The sounding of the acoustic alarm (buzzer) signals that the solenoid valve coil is jammed. This alarm sounds even with the engine at rest and disconnected ignition key.
• Be particularly careful in the following conditions:
A) Safety bars lifted and temporary jamming of the valve. (The engine stops and the acoustic alarm sounds).
Lower the work equipment to the ground (see “3.3.5 MACHINE CONTROLS”), get off the machine and try to locate the trouble.
B) Coil jamming with engine off. (The acoustic alarm sounds).
Lower the work equipment to the ground (see “3.3.5 MACHINE CONTROLS”), get off the machine and try to locate the trouble.
• When the troubleshooting takes long, disconnect the negative pole (-) of the battery, in order not to de- plete it completely.
IMPORTANT
☞
• The green leds (seat and bar) come on only if the operator has engaged all the safety locks and released the parking brake (red led on). The leds go out whenever the bar is lifted (servocontrols off); to reactivate the servocontrols, seat in the driving position, lower the safety bar and press the parking brake push button (green and red leds on).
