INSTRUMENT PANEL INDICATORS

A. ENGINE WATER TEMPERATURE

When the 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 hydraulic drive system malfunction • Defective thermostat.

B. HYDRAULIC OIL TEMPERATURE

When the light is ON, it means that the oil is overheated which could be caused by: • Use of oil with improper viscosity • Low oil level.

C. TRANSMISSION OIL TEMPERATURE

When the light is ON, it means that the oil is overheated and its probable causes are: • Suction line filter clogged • Low oil level • High oil level • Transmission hydraulic oil circuit troubles.

D. PARKING BRAKE

When the light is ON, it means that the brake is actuated.

E. LOW BATTERY CHARGE

When this light is ON, with the engine running, indicates defects in the charging system, caused by: • Defective alternator • Charging resistor damaged

F. LOW TRANSMISSION OIL PRESSURE

When the light is ON, this indicates insufficient oil pressure that may be caused by: • Use of oil with improper viscosity • Low transmission oil level • Defective switch and/or defective panel.

G. LOW ENGINE OIL PRESSURE

When the light is ON, this indicates insufficient oil pressure that may be caused by: • Use of oil with improper viscosity • Low engine oil level • Engine oil leak • Defective pressure switch

INSTRUMENTS/CONTROLS

H. LOW BRAKE OIL PRESSURE

When the light is ON, this indicates insufficient oil pressure that may be caused by: • Pump abnormalities • Air in the brake system • Oil leak on brake lines • Defective pressure switch.

I. AIR FILTER RESTRICTION

When the indicator remains on constantly, the air filter element is clogged and it will be necessary to clean or replaceit. • Defective switch and/or defective panel.

J. HYDRAULIC OIL FILTER RESTRICTION

When the indicator remains on constantly, the oil filter element is clogged and it will be necessary to replaceit.

K. TRANSMISSION OIL FILTER RESTRICTION

When the indicator remains on constantly, the oil filter element is clogged and it will be necessary to replaceit.

L. WARNING FLASHER

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

M. RIGHT TURN SIGNAL N. HIGH BEAM O. LEFT TURN SIGNAL P. SECONDARY STEERING LIGHT (OPTIONAL)

Not available.

4. DIFFERENTIAL LOCK SWITCH OPTIONAL

This switch is used to lock or unlock the differential when it is necessary. Use the differential lock switch only in straight line operation. To steer or articulate the machine the operator must turn off the differential lock switch.

IMPORTANT: Do not turn off the differential lock system when the motorgrader is operating.

5. GEAR AND ERROR CODE DISPLAY

This display shows the actual neutral, forward or reverse transmission gear selected. When an error occurs 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 the key is left in this position without starting the engine, the display will next flash ER100 few times. This designates the revision version of the transmission’s computer software. There is also an error code ER100 but this error code only appears during recalibration. The revision code may change. The next code will be ER101, ER102, etc.

6. STEERING WHEEL TILT LEVER

Loosen the lever and adjust the steering wheel position to obtain more comfortable operating position. Tighten lever again to assure the steering wheel does not move.

7. HOURMETER

The hourmeter indicates operating hours with the engine off and key switch in the RUN position.

INSTRUMENTS/CONTROLS

8. “INCHING” PEDAL

The “inching control pedal” is helpful under the following conditions: • When starting or stopping • For motorgrader finishing work requiring “creeper gear” or very slow speeds • 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). CAUTION: Do not abruptly depress and release inching pedal to start a heavy load or free a stuck machine.

9. 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 to lock the console again.

10. BRAKE PEDAL

This pedal actuates the service brakes. To stop the motorgrader press down on brake pedal. NOTE: Do not descend steep slope using only the service brake. Reduce the speed and apply the brakes. Select an appropriate speed, allowing total machine control. This will avoid brake heating, and will increase the life of the components.

11. ACCELERATOR/DECELERATOR PEDAL

The accelerator/decelerator pedal is connected to the engine throttle controls. To accelerate the engine, press down on the front part of the pedal and to decelerate press down on the rear of the pedal. When the pedal is released, the engine speed will return to the hand throttle setting.

2. THROTTLE CONTROL LEVER

The engine will remain at low idle with the throttle control lever all the way forward and engine speed will increase as the lever is pulled back.

3. TRANSMISSION CONTROL LEVER

SHIFT PATTERN:

R • Reverse F • Forward N • Neutral DS • Down shift US • Up shift The transmission control lever is used to select the desired forward or rearward speeds. These machines are equipped with a 8 speed forward and 4 speed reverse transmission. The gear speed change is done using a shift lever. Toobtain forward speeds place this lever to the front. Toobtain reverse speeds place this lever to the rear. By using this lever the proper speed (1st, 2nd, etc.) can be selected. Observe the gear display readout for confirmation of the gear selected. If the display shows an “error code” it means that some fault has occurred in the transmission system. Therefore it is necessary to contact a NEW HOLLAND dealer. When the machine is stopped, any gear lower than F3 or R2 may be selected to start again. A single speed change is done with a single push and release of shift lever. If the shift control lever is pushed and held to the right or left the gear speeds will change automatically.

NEUTRAL LOCK

LOCK RING

Tomove the shift lever out of neutral position, release the “Neutral Lock” by raising the release ring located under the shift handle knob.

5. GAUGE PANEL

A.ENGINE OIL PRESSURE GAUGE The engine oil gauge indicates the pressure at which the engine oil is circulating through the engine. The red area means insufficient pressure. The green area means normal operating pressure, and the yellow area, excessive engine oil pressure.

INSTRUMENTS/CONTROLS

B.ENGINE COOLANT TEMPERATURE GAUGE • The marker in the GREEN area indicates the normal operating temperature range 80° to 95°C (176° - 203°F) • The WHITE area indicates low temperature. • The RED area indicates high temperature. If during the work cycle, the coolant temperature stays either in the WHITE or RED area, stop the engine to check the cause of the problem. C.FUEL LEVEL INDICATOR GAUGE The green area indicates the normal operating level. Refill the tank using filtered fuel as recommended. Refill the tank at the end of each work day, to avoid water condensation. Never let the fuel tank run-dry, this will cause air to enter the fuel system. Never refill the fuel tank with the engine running. D.TRANSMISSION OIL PRESSURE GAUGE The marker of the transmission oil pressure gauge must stay within the green area which indicates normal operating pressure. If the marker enters the red area, it is a signal that the oil pressure is too low. Do not operate the machine with low transmission oil pressure. Stop and check the cause of the problem. E.TRANSMISSION OIL TEMPERATURE GAUGE The marker must register in the green area. Do not operate the machine when the gauge is in the red area. Stop the machine and determine the cause of high temperature.
