Quincy Vacuum Pump-QSV Series 11
overpressure and make sure that the pump system is at atmospheric pressure level.
8. Never use flammable solvents or carbon tetrachloride for cleaning parts. Take safety precautions
against toxic vapours of cleaning liquids.
9. Scrupulously observe cleanliness during maintenance and repair. Keep dirt away by covering the parts
and exposed openings with a clean cloth, paper or tape.
10. Never weld or perform any operation involving heat near the oil system. Oil tanks must be completely
purged, e.g. by steam cleaning, before carrying out such operations. Never weld on, or in any way
modify, pressure vessels.
11. Whenever there is an indication or any suspicion that an internal part of a machine is overheated, the
machine shall be stopped but no inspection covers shall be opened before sufficient cooling time has
elapsed; this to avoid the risk of spontaneous ignition of the oil vapour when air is admitted.
12. Never use a light source with open flame for inspecting the interior of a machine, pressure vessel, etc.
13. Make sure that no tools, loose parts or rags are left in or on the machine.
14. All regulating and safety devices shall be maintained with due care to ensure that they function
properly. They may not be put out of action.
15. Before clearing the machine for use after maintenance or overhaul, check that operating pressures,
temperatures and time settings are correct. Check that all control and shut-down devices are fitted and
that they function correctly. If removed, check that the coupling guard of the vacuum pump drive shaft
has been reinstalled.
16. Every time the separator element is renewed, examine the discharge and the inside of the oil separator
vessel for carbon deposits; if excessive, the deposits should be removed.
17. Protect the motor, air filter, electrical and regulating components, etc. to prevent moisture from entering
them, e.g. when steam cleaning.
18. Make sure that all sound damping material and vibration dampers, e.g. damping material on the
bodywork and in the air inlet and outlet systems of the vacuum pump are in good condition. If
damaged, replace it by genuine material from the manufacturer to prevent the sound pressure level
from increasing.
19. Never use caustic solvents which can damage materials of the air net, e.g. polycarbonate bowls.
20. Faults or wearing of seals may cause oil lubricant leaks. Avoid dispersion in soil and pollution of other
materials.
NOTICE!
Also consult sections Safety precautions during installation and Safety precautions during
operation.
These precautions apply to machinery processing or consuming air or inert gas. Processing of any
other gas requires additional safety precautions typical to the application which are not included
herein.
Some precautions are general and cover several machine types and equipment; hence some
statements may not apply to your machine.
