The bleeding of the in---line pump system differs from the
bleeding of the distributor pump system as follows:
--- The fuel hand priming pump (1) is located beside the
injection pump. Continue pumping a few times to fill the
injection pump, then tighten the bleeding screw (2)
--- The fuel from the injection pump can also be bled
through the overflow valve (3) after bleeding the fuel
filters.

the fuel container is empty e.g. after service. damage to
the glow plug can occur due to the lack of fuel when
starting the engine.

can through the breather hole (2) on the cover.
--- Open the glow plug pipe adapter (3).
I 1.2. Air cleaner
69---90
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.
CAUTION: 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.
I 1.2.1. Maintenance of main filter
A3565---127
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.
NOTE: 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.
