Notes:
1. Maintenance must be done according the number of running hours or according the running period,
whichever comes first.
2. More frequently in a dusty environment.
3. Important note: Greasing of the bearings of the compressor element must be done with special
grease, a special grease gun and according a specific procedure.
In high ambient conditions, the bearings must be greased more frequently: for every 5 °C (9 °F)
increase above 30 °C (86 °F), the maintenance interval should be reduced with 30 %.
Contact your supplier for details.
4. In extremely dry conditions (relative humidity below 15 %), the tip seals and dust seals need to be
replaced more frequently.
