5.3 Leybold Service
Whenever you send us in equipment, indicate whether the equipment is contami-
nated or is free of substances which could pose a health hazard. If it is contami-
nated, specify exactly which substances are involved. You must use the form we
have prepared for this purpose.
A copy of the form has been reproduced at the end of these Operating Instruc-
tions: “Declaration of Contamination for Compressors, Vacuum Pumps and Com-
ponents”. Another suitable form is available from: www.leybold.com → Down-
loads → Download Documents → Declaration of Contamination.
Attach the form to the equipment or enclose it with the equipment.
This statement detailing the type of contamination is required to satisfy legal re-
quirements and for the protection of our employees.
We must return to the sender any equipment which is not accompanied by a con-
tamination 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.
5.4 Oil level
The oil level should be checked at least once a day. If the oil level is below the
“MAX” mark, oil has to be added until the level reaches the mark. If the oil level is
below the “MIN” mark, stop the pump and check it.
5.5 Oil changing
Oil must be changed after the first 150 operating hours. Further oil changes, de-
pending on operating conditions (products, vapors, ambient temperature…) must
be done every 500 to 2000 operating hours or at least every 6 months.
A oil quality label stuck to the pump helps user judge if oil should be changed or
not.
When oil color reaches “CHANGE” shade, it is a signal to change oil.
oil change frequency given by oil label is just informative, the real oil life time de-
pends on chemical characteristics.
-
If the viscosity at 25 °C exceeds 0.3 Pa s, the oil should be changed.
- The neutralization value is determined according to DIN51558. If it reaches 2,
the oil should be changed.
User can decide a postponement of oil change based on their experience and
professional management. In case of doubt, don’t risk operation with used oil, it’s
preferable to replace oil.
If there is considerable pollution, it could be necessary to change the oil more
frequently. Oil changing must be done with a switched off and still warm pump.
Open the oil drain plug and let run out the used oil into an appropriate container.
Refasten the oil drain plug when oil runs slower, start up the pump briefly (5 sec.
max) and switch off immediately. Reopen the oil drain plug and drain the rest of
the oil.
Before refastening the oil drain plug, inspect the O-ring and if necessary replace
it. Open the oil fill plug and pour in clean oil ; refasten the oil fill plug. The pump
has to be rinsed out if there is considerable pollution. Therefore pour in clean oil
up to the low edge of the oil level glass, let the pump run briefly (for a few
minutes) then drain the oil again.
