dB(A) shall wear ear protectors.
8.
Periodically check that:
All guards are in place and securely fastened
All hoses and/or pipes inside the machine are in good condition, secure and not rubbing
There are no leaks
All fasteners are tight
All electrical leads are secure and in good order
Air inlet valve and air net, that is pipes, couplings, manifolds, valves, hoses, and so on are in
good repair, free of wear or abuse
9.
If warm cooling air from vacuum pumps is used in air heating systems, e.g. to warm up a workroom,
take precautions against air pollution and possible contamination of the breathing air.
10. Do not remove any of, or tamper with, the sound-damping material.
11. Never remove or tamper with the safety devices, guards or insulation fitted on the machine.
12. Do not change the purpose of the pump. If the pump is configured to be used as a vacuum pump, do
not use the pump as an overpressure pump. If the pump has been configured to be used as an
overpressure pump, do not use the pump as a vacuum pump.
13. Never run the overpressure pump without the air intake filter mounted. For the vacuum pump,
Edwards recommends to install an air intake filter to safeguard the pump. Consult Edwards to check
whether the application for the vacuum pump requires and air intake filter.Never remove or tamper
with the safety devices.
Note:
Also consult following safety precautions: Safety precautions during installation and Safety
precautions during maintenance or repair.
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.
