Attach the form to the equipment or enclose it with the equipment.
This statement detailing the type of contamination is required to satisfy legal
requirements and for the protection of our employees.
We must return to the sender any equipment which is not accompanied by a
contamination statement.
The pump must be packaged in such a way that it will not be damaged
during shipping, and so that no harmful substances can escape from the
package.
When disposing of used oil, please observe the relevant environmental
regulations.

Maintenance Work

Checking the oil
A. Oil level
The pump's oil level during operation must always be between the middle
and top edge of the oil-level glass (164). When necessary, switch off the
pump and add the correct quantity of oil.
High oil consumption often indicates that exhaust filters are clogged
(See 5.4 - D).
The oil level should be checked at least once a day.
B. Oil Condition GS77
Normally the oil is clear and transparent. If the oil darkens, it should be
changed.
If gases or liquids are dissolved in the oil, the result is a deterioration of the
ultimate pressure, the oil can be degassed by allowing the pump to run for
about 30 min. with the intake port closed and the gas ballast valve open.
To check if oil should be changed, drain some oil via the oil-drain plug (5)
into a beaker or similar container with the pump switched off but still at
operating temperature.
