WARNING
_ab
Risk of electrical shock, risk of damage to equipment.
Electrical installation work must only be executed by qualified personnel that knows and observes the following regulations:
- IEC 364 or CENELEC HD 384 or DIN VDE 0100, respectively,
- IEC-Report 664 or DIN VDE 0110,

CAUTION
_ac
During operation the surface of the vacuum pump may reach temperatures of more than 70 °C.
Risk of burns!
Let the vacuum pump cool down prior to a required contact or wear heat protection gloves.
Problem Possible Cause Remedy
The vacuum pump does not reach the usual
pressure
The drive motor draws a too high current
(compare with initial value after commission-
ing)
Evacuation of the system takes too long
The vacuum system or suction line is not
leak-tight Check the hose or pipe connections for possi-
ble leak
In case a vacuum relief valve/regulating system
is installed:
The vacuum relief valve/regulating system is
misadjusted or defective
Adjust, repair or replace, respectively
Contaminated oil (the most common cause) Change the oil
( page 8: Maintenance)
No or not enough oil in the reservoir Top up oil
( page 8: Maintenance)
The exhaust filter is partially clogged Replace the exhaust filter
( page 8: Maintenance)
The screen in the suction connection (c) is par-
tially clogged Clean the screen
If cleaning is required too frequently install a
filter upstream
In case a filter is installed on the suction
connection (c):
The filter on the suction connection (c) is par-
tially clogged
Clean or replace the inlet air filter, respectively
Partial clogging in the suction, discharge or
pressure line Remove the clogging
Long suction, discharge or pressure line with
too small diameter Use larger diameter
The valve disk of the inlet non-return valve is
stuck in closed or partially open position Disassemble the inlet, clean the screen and the
valve as required and reassemble
A shaft seal is leaking Replace the shaft seal ring (Busch service)
A vane is blocked in the rotor or otherwise
damaged Free the vanes or replace with new ones
(Busch service)
The radial clearance between the rotor and
the cylinder is no longer adequate Readjust the vacuum pump (Busch service)
Internal parts are worn or damaged Repair the vacuum pump (Busch service)
