WARNING: You must respect the operating conditions for the different ingredients.

Hydraulic fluid

Greases

The CASE hydraulic fluid is specially adapted for high pressure and CASE’s hydraulic circuit. The type of fluid to be used depends on the ambient temperature.

The type of grease to be used depends on the ambient temperature.

Temperate climates -20°C to +40°C Fluid type: ISO VG 46 CASE reference: POHYDR

Hot climates 0°C to +60°C Fluid type: ISO VG 100 CASE reference: POHYPC

Engine oil The CASE No. 1 engine oil is recommended for your engine. This oil ensures proper lubrication of your engine for all operating conditions.

If you are unable to procure the CASE No. 1 Multiperformance or Performance engine oil, use the corresponding oil from the API/CG/CF category.

NOTE: Do not put any performance additives or any other additives in the engine housing. The oil changing intervals are indicated in this manual based on tests carried out on CASE lubricants.

Fuel

Environment

The fuel to be used must comply with the D975 norm of the American Society for Testing and Materials (ASTM).

Before carrying out any maintenance operation on this machine and before throwing away the liquids or lubricants used, always think of the environment.

Never throw oil or liquids on the ground and never put them in leaking containers.

Use type No. 2 fuel, use of other fuels can cause a loss of engine power and excessive fuel consumption.

In cold weather, it is provisionally accepted that a mixture of No. 1 and No. 2 fuels be used. Contact your fuel supplier.

If the temperature drops below the freezing point of the fuel (point where paraffin appears), paraffin crystals in the fuel will cause loss of engine power or starting trouble.

IMPORTANT: In cold weather, fill up the reservoir with fuel after each workday, in order to avoid the formation of condensation.

Consult your local centre for ecological recycling for information on the appropriate method for disposing off these substances.

Plastic and resin parts When cleaning plastic parts, on the console, the instrument panel, the indicator and gauges etc., do not use petrol, paraffin, paint solvents, etc. Use only water, soap and a soft cloth.

The use of petrol, paraffin, paint solvents etc... causes discoloration, cracks or deformation of these parts.

Storing fuel Prolonged storage of fuel promotes the accumulation of foreign bodies or condensed moisture in the storage tank. Many engine failures are caused by the presence of water in fuel.

The storage tank must be placed outside and the fuel should be maintained at as low a temperature as possible. Drain the condensed moisture at regular intervals.

Antifreeze/anticorrosive Use the antifreeze in all seasons to protect the coolant system from corrosion and to avoid any risk of freezing.

In environments with a temperature greater than -36°C, use a 50% mixture of antifreeze in an ethylene glycol base.

In environments with a temperature less than -36°C, it is recommended that you use a 40% water and 60% antifreeze mixture.

2) Fuel consumption checking

4) Engine checking when stopped

1. The engine controller (A2) calculates the target speed on the basis: - of data on the work mode sent through CAN communications from the computer (A1), - on the voltage signals of the throttle volume (R3), - on the voltage signals of the water temperature sensor (B1) - of the voltage signals (key switch S1) that power the engine controller.

When the engine controller receives the engine stop signal (when the ignition is turned off or the emergency stop (S9) is activated), it (A2) transmits the rack "no injection" position signal to the electronic acceleration (A3) and activates the engine stop signal.

2. The engine controller (A2) calculates the fuel flow by analysing the difference between the target speed (electronic acceleration tachometric sensor) and the actual speed (engine rpm sensor (B41).

3. The engine controller (A2) converts the fuel flow in the target position of the electronic acceleration rack (A3) and corrects this target position according to the adjustment regulator (R2).

3) Engine checking while starting 1. By putting the switch (S1) in the start position, the start signal is sent simultaneously to the starter motor and the engine controller (A2).

5) Electronic acceleration power-assist error and back-up mode 1. The rack sensor signal comes to the engine controller (A2).

2. The engine controller (A2) compares the target position and the actual position of the rack.

3. If the engine controller (A2) determines that the rack is not in its correct target position, it considers it as a power-assist error and stops the engine.

4. If the back-up mode is activated during an electronic acceleration power-assist error (A3), the engine runs in back-up mode (see chapter on back-up mode).

2. The engine controller (A2) determines the fuel flow injection. This flow is determined by the data on the water temperature and the actual engine rpm.

3. Once the start signal is switched off, the engine controller (A2) goes from start fuel control to normal flow injection control.

3) Mode selection switch

4) Operation

a)

When the ignition switch is turned on, the "S" mode is selected by default (except if auto mode was selected at the time of turning off the ignition switch).

1. The work mode (S3) and auto mode (S4) switches signal is managed by the computer (A1) that changes the mode according to the input signal.

b)

Each time the work mode switch (S3) is pressed, the mode changes: S→H→L→S→H

c)

If the auto mode switch (S4) is activated, the mode changes to auto mode. If the auto mode switch (S4) is pressed once again, the mode changes to "S" mode.

d)

When auto mode is activated, if the work mode switch (S3) is pressed, the work mode does not change.

e)

After turning off the ignition switch in auto mode, when the ignition switch is turned on again, the mode remains automatic.

Cre 9-40330GB

2. The computer (A1) transmits the selected mode to the monitor display (P4) via series communication (2). The monitor display (P4) displays the selected mode.

3. The computer (A1) transmits the selected mode to the engine controller (A2) via CAN communications that control the electronic acceleration (A3).

The engine controller (A2) transmits the mode and the data concerning the rpm to the computer (A1) via CAN communications.

4. The computer (A1) calculates the proportional solenoid (Y7) current based on the selected mode and the data on the actual rpm and the target rpm of the engine.

5. The computer (A1) transmits the new data to the monitor display (P4) via series communications.

NOTE: The values listed above are those in normal conditions, the following are exceptions: 1. If the target engine rpm is less than the maximum torque rpm, the pump is controlled by the "L" mode current value (same in H/S modes).

3. In "L" mode, if the hydraulic breaker or the grab is used, the pump is controlled by the "S" mode current value.

2. In "L" mode, if only travel is selected, the pump is controlled by the "S" mode current value.

4. If the engine coolant temperature is too low, or if the voltage coming in to the engine controller (A2) is too low, the idle rpm increases to avoid over-cooling of the engine or discharging of the battery.
