Check and adjustment instructions for the extra

equipment are in section K, after each extra equipment.

I1.1. Bleeding fuel system

There should be no air in the fuel system to ensure that

the motor function is of maximum efficiency. The system

automaticly removes the small guantity of air which has

built up in the filters and injection pump. The fuel system

must be bled if any part of it has been removed or if the

tractor has run out of fuel during driving so that air has

entered the system. Bleed the fuel system as follows:

2. Start the engine to the low idling, do not race. If the

engine does not start, open the union (2)oftheblee-

ding pipe from the fuel filter to the injectors. Pump by

hand pump, until the fuel is running out from the union.

Tighten the union and dry the fuel overflowed.

IMPORTANT: Do not open the union in the upper part

of the prefilter, because it is on the suction side.

3. Start the engine and check that there are no leaks.

I1.2. Air cleaner

The air cleaner prevents dust and other dirt from entering

the engine with the induction air. Engine wear is largely

dependent on the cleanliness of the induction air so it is
