9. Checks and Adjustments
Check and adjustment instructions for the extra
equipment are in section ‘’11’’, after each extra
equipment.
9.1. Engine
9.1.1. Bleeding fuel system
There should be no air in the fuel system to ensure
that the motor function is of maximum efficiency.
The system automatically removes the small
quantity 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:
1. Get out of the high pressure line hose record (1)
from the feed pump.
2. Start the engine to the low idling, do not race.
3. Wait for the continuously flowing. Until the fuel is
running out from the union (with out air bubbles)
tighten the hose record connection onto the feed
pump.
IMPORTANT: Do not open the union in
the upper part of the pre-filter, because
it is on the suction side.
4. Start the engine and check that there are no
leaks.
9.1.2. 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 very important to check the air
cleaner regularly and to maintain it correctly.
IMPORTANT: The safety filter inside
the main filter must not be cleaned but
must always be changed according to
the maintenance schedule. The
purpose of the safety filter is to
prevent damage to the engine if the main filter
should fail.
9.1.2.1. Maintenance of main filter
The air filter must not be cleaned more than five
times, after which time it must be replaced. Check
when cleaning that the filter and its seals are
undamaged. A damaged filter must always be
replaced.
IMPORTANT: Never clean or remove
the air filter unless it is absolutely
necessary. When removing the air
filter there is always the possibility that
dirt can enter the induction system of the engine.
