21.7.2 Maintenance
It is very important to keep the system free from dirt and
condensate to achieve troublefree function. See section 21.5.
Vent the servo lubricator circuit when starting up a new motor
or if, by mistake, the oil container went empty.
If the servo lubricator circuit is not thoroughly vented the
starting motor will get no lubrication and may be damaged.
21.7.3 Venting
1 Loosen the air connection from the lubricator (10) and
the oil connection from the non-return valve (11).
2 Plug up the oil pipe opening
with a finger and, by
means of an air nozzle, blow compressed air into the air
connection several times until oil emerges from the oil pipe. If
compressed air is not available, the connection “1” on the valve
(7) can be opened and the valve can be connected to the
servolubricator air connection. Then it is possible to use the
normal start button of the engine for venting without starting
the engine.
Warning! When using the start button of the engine when venting as
described above, connection on the valve (7) must absolutely
be removed. Otherwise the engine will start when venting.
3 Connect the pipe to the non-return valve (11) and check
that oil is supplied through the valve when blowing com-
pressed air.
4 Apply all pipes to the initial connections.
5 Check function during a few starts. When pressing the
start button, oil level in the glass tube should momentarily
drop by 15 - 20 mm and then rise to a level corresponding the
oil level in the container.
Regularly check that the oil level stays between the maxi-
mum and minimum marks. Use some of the following oils:
•
GALI HJ 33 EP
•
SHELL TURBO 27
•
CASTROL HYSPIN 80
•
BP ENERGOL HP 46
•
MOBIL DETERGENT LIGHT.
The oil brands are also engraved on the container.
In case of possible malfunction, see manufacturer’s instructions
