Replacing indictor tube
Risk of damage to eyes! If not properly secured, the indicator tube might be
propelled out of its holder!
When the needle valve is opened, the indicator tube is secured by a union
nut. If
- the union nut is not properly tightened, or
- if the oil indicator has been interfered with,
there is a risk that the tube might be propelled by the air fl ow so that it is shot
out of its holder.
When working at the oil indicator, always wear protective goggles.
Prior to opening the needle valve, check that the union nut at the indicator tube
is properly tightened.
The colour change of the tube segments (2) is irreversible.
When all segments have changed colour, the indicator tube
must be replaced.
Prior to removing the tube:
Ensure that the needle valve (1) is closed and that the indi-
cator tube (2) is not under pressure. To close the needle valve,
turn its handle clockwise.
To remove the indicator tube:
Loosen the reducer (4) below the union nut (3), using an
appropriate tool.
Dispose of spent indicator tube and reducer according to
the application regulations.
