This lever allows the operator to activate the floodlights and headlights by turning its end forward. The first position forward is floodlight, the second is low beam. Pressing the lever down, it lights high beam, consequently turning off low beam. With the lever in its neutral position the high beam flashes by pulling it up. Moving the lever forward or backward it will flash right (forward) or left (backward) turning signals.

F- Right turning signal N- Neutral R- Left turning signal TOP VIEW

2 - STEERING WHEEL

The steering wheel is attached to an orbitrol steering control unit. The orbitrol is a combination valve and oil pump which is responsible for the supply of oil to the steering cylinder. The steering wheel may be tilted to achieve a better operator's working position using steering wheel tilt lever.

3- ELECTRONIC MONITOR, SPEEDOMETER, HOURMETER AND ENGINE RPM DISPLAY DIGITALS This control panel indicates any problem in machine function. For easy identification the signals are transmitted with LED's.

This electronic monitor permits the operator to better control all the machine functions from his work station.

FUNCTIONAL DESCRIPTION

Checks on electronic monitor:

1)With engine shut-off and ignition key switch in the RUN (IGN) position all the electrical circuits are turned on.

The LED indicator lights flash in all functions for a few seconds (test phase).

When the engine starts and the key goes back to start position. The electronic monitor will turn OFF. Only the parking brake light will stay ON if they are activated. When the ignition key goes is released and returns to the run position. The electronic monitor will do the check again. 2)After the test phase the following indicators will be turned off until the engine is turned off: - Low battery charge, E; - Low transmission oil pressure, F; - Low engine oil pressure, G; - Low brake oil pressure, H; - Parking brake (when the lever is pulled up), D.

All the LED's indicators quoted above will turn off except parking brake D (when the lever is pulled up), and brake pressure H.

3)If any abnormalities happen (for the functions described on this monitor), the LED light corresponding and the warning red light will flash followed by warning sound (see item 4).

4)The following LED's indicators do not activate the sound warning: - Parking brake, D; - Steering supplemental (optional), P; - Differential lock, T; - General warning light, L; - High beam, N; - Turning signals, O and M.

5)The differential lock functions only with the parking brake disengaged and only in first to seventh gears.

6)Q Speedometer registers the travel speed.

R Indicates the engine RPM during operation.

S The RPM gauge will indicate operating hours when it is energize, but the engine not running.

INDICATOR LIGHTS:

A. ENGINE WATER TEMPERATURE

When this light is ON, it means that the engine coolant has overheated which could be caused by:

- Lack of coolant in the system; - Radiator cooling fins clogged; - Radiator circuit clogged; - Fan belts loose; - Abnormalities in the circuit functions, a defective panel or a defective thermostat.

B. HYDRAULIC OIL TEMPERATURE

When this light is ON, it means that the oil has overheated and the probable causes are:

- Use of oil with improper viscosity;

- Low oil level;

- Abnormalities in the circuit functions;

- Defective panel .

C. TRANSMISSION OIL TEMPERATURE

When this light is ON, it means that the oil has overheated that may be caused by:

- Suction line filter clogged; - Low oil level; - Transmission hydraulic oil circuit troubles ; - Abnormalities in circuit functions or a defective panel.

D. PARKING BRAKE

When this light is ON, it means that the parking brake is actuated. E. LOW BATTERY CHARGE INDICATOR

When this light is ON with the engine running it indicates defects in the charging system, caused by:

- Defective alternator;

- Charging resistor damaged; - Abnormalities in the circuit functions.

F. LOW TRANSMISSION OIL PRESSURE

When this light is ON, it indicates insufficient oil pressure that may be caused by:

- Use of oil with improper viscosity; - Low transmission oil level; - Transmission oil leak; - Problem in the transmission oil circuit; - Defected switch or a defective panel.

G. LOW ENGINE OIL PRESSURE

When this light is ON, it indicates insufficient oil pressure that may be caused by:

- Use of oil with improper viscosity; - Low engine oil level; - Engine oil leak; - Problem in the engine oil circuit; - Defective pressure switch; - Abnormalities in the circuit functions or a defective panel.

H. LOW BRAKE OIL PRESSURE

When this light is ON, it indicates insufficient oil pressure that may be caused by: - Pump abnormalities; - Air in the brake system; - Oil leak in the brake lines; - Brake lines cracked; - Defective pressure switch; - Abnormalities in circuit functions or defective panel.

Study SAFETY RULES in the front of this manual thoroughly for the protection of machine and safety of personnel. 45

I. AIR FILTER RESTRICTION INDICATOR

When this indicator remains on constantly, the air filter element is clogged and it will be necessary to clean or replaced it. - Defective switch or a defective panel.

J. HYDRAULIC OIL FILTER RESTRICTION INDICATOR

When this indicator remains on constantly, the oil filter element is clogged and it will be necessary to clean or replace it. - Defective switch or a defective panel.

K. TRANSMISSION OIL FILTER RESTRICTION INDICATOR

When this indicator remains on constantly, the oil filter element is clogged and it will be necessary to clean or replace it. - Defective switch or a defective panel.

L. WARNING FLASHER

This indicator flashes when its button located on the right console is pressed in.

M. RIGHT TURN SIGNAL

N. HIGH BEAM

O. LEFT TURN SIGNAL P. SUPPLEMENTAL STEERING LIGHT (OPTIONAL) This light signals that the supplemental steering pump is functioning. Test the system every day before begining operations by turning the ignition switch to the "IGN" position. A light movement of the steering wheel will start the electric motor driven steering pump and the light "P" will flash. Stop the test by starting the engine. Minimize the time in test mode to avoid draining the battery. The system functions automatically in case the primary steering should cease functioning.

4- OPTIONAL - DIFFERENTIAL LOCK SWITCH

This switch is used to lock or unlock the differential when it is necessary.To maneuver this machine the operator must turn off the differential lock switch. When the machine is moving the use of this switch is not allowed. 5- GEAR AND ERROR CODE DISPLAY

This display shows the actual neutral, forward or reverse transmission gear selected. When an error has occurred the display will flash an error code indicating that a problem has been detected in the system. When the ignition key is first turned on, the display will show three sets of double letters (TD DC ER) at the top and three (8)'s. The first (8) will have a diagonal line through it. This is a system light check. If key is left in this position without starting the engine, the display will next flash ((ER100) a few times. This designates the revision version of the transmission's computer software. There is also an error code ER100 but this error code can only appear during re-calibration. The revision code can and eventually will change. The next code will be (ER101), ( ER102), etc.

6- STEERING WHEEL TILT LEVER

Loosen the lever and adjust the steering wheel forward or back to obtain a more comfortable operating position. Then tighten lever again to assure the steering wheel does not move.

7- "INCHING" PEDAL

The "inching control pedal" is helpful under the following conditions: - Use when starting or stopping. - Use for grader finishing work requiring "creeper gear" or very slow speeds. - Use for very slow ground speed work to increase engine speed for hydraulic performance (this should rarely be necessary because of the wide range performance of the hydraulic system).

WARNING

Do not abruptly depress and release inching pedal to start a heavy load or free a stuck machine.

8- CONSOLE TILT PEDAL

The console may be adjusted to improve operator comfort. Push the pedal to free the console. Position the console in the desired position and then release the pedal so it will lock the console again.
