Opening the hood

To access the engine components and carry out inspec-

tion, lubrication and maintenance operations, the bonnet

must be opened (1). The following instructions describe

the procedure to be followed.

The hood is hinged at the rear to allow easy and safe

access to the various engine components.

To open the bonnet, insert the engine starter key into the

hole shown (on the front of the bonnet) and press on the

catch to unhook the bonnet. Raise the bonnet with the

special handle, an internal strut will keep it in the raised

position.

Engine Oil

The correct degree of engine oil viscosity depends on the

environment temperature. Refer to the chart on the right

when selecting the oil grade for your tractor engine.

NOTE: In areas where prolonged periods of extreme tem-

peratures are encountered, local lubrication practices are

acceptable. The use of SAE 5W with extremely low tem-

peratures and SAE 50 for extremely high temperatures is

advised.

Engine oil and filter

T4.75F — T4.85F

NOTE: This operation describes the process of draining oil from the engine sump and changing the relevant oil filter.

The frequency of 500 hours can anyhow be affected by other factors:

Cold temperature operation

Engines operating in temperatures below -12 °C (10.4 °F)

or in arduous conditions should have the oil changed every

300 hours of operation. The filter must be changed regu-

larly as prescribed.

Diesel fuel sulphur content

In some countries, locally available diesel may have a high

sulphur content, in which case the oil and filter should be

changed sooner, as follows:

Sulphur content between 0,5 - 1,0 % change oil every 300

hours;

Sulphur content between 1,0 - 1,3 % change oil every 150

hours;

If in doubt, or if it is not possible to check the instructions

Keep the top part clean and dry. Check that the fluid

level reaches the top mark and never drops under the

bottom mark. If necessary lift covers (1) and add ONLY

distilled water.

Check the charge with a digital voltmeter in the follow-

ing way:

• Connect the voltmeter to the battery’s two terminals,

matching the terminal symbols (negative to negative

and positive to positive) and read the value from the

instrument

• Compare the figure with the values in the table below
