Screw-on type oil filter
A tape wrench is a suitable tool for un-
screwing the disposable filter box.
Caution:
The filter box is full of hot oil. Hold a
suitable vessel under the filter box to
catch the oil which flows out.
Apply light coating of oil on gasket.
Screw on filterbox and tighten by hand.
Fill engine with oil. Run engine for a short
period and check filter for possible leaks.
Retighten if necessary.
Every time oil change is made, the filter
cartridge should be renewed.
Caution:
Used oil filters are classed as danger-
ous waste and must be disposed of
accordingly.
Fuel system
Fuel
If Diesel fuel which contains moisture is
used the injection system and the cylinder
liners / pistons will be damaged. This can
be prevented to same extent by filling the
tank as soon as the engine is switched off
while the fuel tank is still warm (formation
of condensation is prevented). Drain
moisture from storage tanks regularly. In-
stallation of a water trap upstream of the
fuel filter is also advisable. Do not use any
additives to improve flow properties in
winter.
Injection pump
No alterations must be made to the injec-
tion pump. If the lead seal is damaged the
warranty on the engine will become null
and avoid.
Faults
We urgently recommend that you have
faults in the injection pump rectified only in
an authorised specialist workshop.
Bleeding the fuel system
Bleeding the fuel filters is by releasing the
bleed screws and operating the manual
primer (fit new seals).
The suction chamber of the injection
pump is continuously bled via the relief
valve during operation. If the suction
chamber is completely empty, e.g., when
fitting a new pump, filling and bleeding it is
by actuating the manual primer.
