the pump.
Danger of explosion!
If requirements are not met, the vacuum pump may not be switched
on!
Should work exceed the dismantling work described in this
handbook, it may only be carried out by authorised persons.
DANGER
If the vacuum pump has pumped gases that were contaminated
with foreign bodies that are hazardous to health, the oil and con-
densate are also contaminated with these foreign bodies.
These foreign bodies can penetrate into pores, openings and other
internal parts of the vacuum pump.
There is a health hazard when dismantling the vacuum pump.
There is also a danger to the environment.
Prior to shipping, the vacuum pump must imperatively be decon-
taminated and the degree of contamination must be documented in
a declaration of decontamination (“Declaration of Decontamina-
tion”), which can be downloaded from www.buschvacuum.com.
Busch service will only accept vacuum pumps that come with a
completely filled in and legally binding signed form.
