Important
• Always consult your supplier if a timer setting has to be changed.
• For the change interval of oil and oil filter in extreme conditions of temperature,
humidity or cooling air, consult your supplier.
• Any leakage should be attended to immediately. Damaged hoses or flexible joints
must be replaced.
• For change of oil contact Atlas Copco for the correct procedure.
• For changing of one type of oil to another type of oil consult Atlas Copco for the
correct procedure as this is not allowed in some conditions.
8.2 Oil specifications
It is strongly recommended to use genuine Atlas Copco Lubricants. They are the result of years
of field experience and research. See section Preventive maintenance schedule for the advised
replacement intervals and consult your Spare Parts list for part number information.
Avoid mixing lubricants of different brands or types as they may not be compatible and
the oil mix may have inferior properties. A label, indicating the type of oil filled ex factory,
is stuck on the air receiver/oil tank.
Roto-Inject Fluid NDURANCE
Atlas Copco's Roto-Inject Fluid NDURANCE is a premium mineral oil based 4000 hours lubricant,
specially developed for use in single stage oil injected screw compressors running in mild
conditions. Its specific formulation keeps the compressor in excellent condition. Roto-Inject Fluid
NDURANCE can be used for compressors operating at ambient temperatures between 0 ˚C
(32˚F) and 40 ˚C (104 ˚F). If the compressor is regularly operating in ambient temperatures
above 35°C (95 °F), it is recommended to use Roto Synthetic Fluid ULTRA or Roto Synthetic
Fluid XTEND DUTY.
