Periodic Maintenance
Figure 1
:
Check the oil level and condition.
Level:
The pump’s oil level during operation must
always be ½ to ¾ full on the oil-level sight glass. When
necessary, switch off the pump and add the correct
quantity of oil. Overfilling can lead to oil losses at high
intake pressures. High oil consumption often indicates
that the exhaust filter is clogged.
Condition:
Normally the oil is clear and transparent. If
it darkens, then it should be changed.
Figure 2
:
Check the silicon seal pad in the top
of the lid. The silicon seal pad should not be
burnt or worn.
Figure 3
:
Check the sealing gasket in the lid.
The sealing gasket should completely cover
the outer edges of the lid. Make sure there are
no gaps or tears in the gasket.
Figure 4
:
Check the seal bar Teflon tape and
seal element. The seal tape and element
should not be burnt or worn.
Figure 5
:
Check the CoreLok lid and glass
viewing window. The lid and window should
not be stressed or cracked.
