Also consult following safety precautions: Safety precautions during operation and Safety 
precautions during maintenance. 
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. 
 
1.4  Safety precautions during operation 
All responsibility for any damage or injury resulting from neglecting these precautions, or 
non-observance  of  the  normal  caution  and  care  required  for  installation,  operation, 
maintenance  and  repair,  even  if  not  expressly  stated,  will  be  disclaimed  by  the 
manufacturer. 
 
1.  Never touch any piping or components of the pump during operation. 
2.  Use  only  the  correct  type  and  size  of  hose  end  fittings  and  connections.  Make  sure  that  a  hose  is  fully 
depressurized before disconnecting it. 
3.  Persons switching on remotely controlled machines shall take adequate precautions to ensure that there is no 
one checking or  working on the machine. To this end, a suitable notice shall be affixed to the remote start 
equipment. 
4.  Never operate the machine when there is a possibility of taking inflammable or toxic fumes, vapors or particles. 
5.  Never operate the machine below or in excess of its limit ratings. 
6.  Keep all bodywork panels shut during operation. The panels may be opened for short periods only, for example, 
to carry out routine checks. Wear ear protectors when opening a panel. On vacuum/over-pressure pumps without 
bodywork, wear ear protection in the vicinity of the machine. 
7.  People staying in environments or rooms where the sound pressure level reaches or exceeds 80 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 over-pressure pump. If the pump has been configured to be used as an over-pressure pump, do not 
use the pump as a vacuum pump. 
13. Never run the over-pressure pump without the air intake filter mounted. For the vacuum pump, Atlas Copco 
recommends to install an air intake filter to safeguard the pump. Consult Atlas Copco to check whether the 
application for the vacuum pump requires and air intake filter.
