Safety Information 

 

1.4

 

FIRE AND EXPLOSION

 

Clean up any spills of lubricant or combustible liquid immediately. Keep sparks and flame 
away  from  the  compressor.  Do  not  permit  smoking  during  servicing,  such  as  checking  or 
adding fluid. Wipe down spills immediately using industrial cleaner as required. Do not use 
flammable  material  for  cleaning  purposes.  Do  not  operate  the  compressor  in  a  hazardous 
environment unless the compressor has been specially designed for that environment. Wear 
personal  protective  equipment  including  safety  goggles  and  clothing  during  servicing  the 
compressor. Never use a flammable or toxic solvent for cleaning the air filter or any parts. 

 

1.5 MOVING PARTS 

Keep hands,  arms and cloths  away from the coupling and fans  of the compressor. Do not 
remove  any  guards  or  cabinet  panels  or  attempt  to  service  any  compressor  part  while  the 
compressor is operating. 

 

1.6 HOT SURFACES 

Do not  touch  any hot  surface and parts during the compressor’s  operation. Keep all body 
parts away from air/oil receiver tank, steel tubing, air end and after-cooler. Wear personal 
protective equipment including gloves while servicing the compressor. 

 

1.7 PROPER COMPRESSED AIR APPLICATIONS 

Air  from  this  compressor  will  cause  severe  injury  or  death  if  used  for  breathing  or  food 
processing.  Air  used  for  those  processes  must  meet  OSHA  and  applicable  industry 
regulations. This compressor is designed for use in the compression of normal atmospheric 
air only. No other gases, vapors or fumes should be exposed to the compressor intake, nor 
processed through the compressor. Keep personnel away from the compressed air discharge. 
Use  compressed  air  for  cleaning  purpose,  only  with  effective  chip  guarding  and  personal 
protective  equipment  which  meet  OSHA  standard  and/or  any  federal,  state,  local  codes, 
standard and regulation.
