10.1 Maintenance recommendations
10.2 Maintenance Electric Motor
10.2.1 Motor Lubrication
The motors used with this compressor package have
sealed bearings which have been greased at the
factory and require no re-greasing during their
operational life. These motors do not have injection or
drain ports for re-greasing.
10.3 Maintenance and inspection
schedule
Intervals are valid for normal industrial
environments and operating conditions. If there is
some uncertainty, set the oil change interval by
performing oil analysis.
In the case of a very dirty atmosphere, the cleaning
intervals have to be shortened as required.
For order numbers see the spare parts list.
WARNING
High voltage
– Hazard of shock, burn, or
death
Be careful with electricity: only work on
screw compressors which are not
powered.
Only for L30RS-L45RS: There is a risk of
electric shock from charged capacitors!
Disconnect the system from the mains
and wait 10 minutes before touching
electrical components. The power
capacitors need this time to discharge.
DANGER
Rotating machinery can cause injury or death. Open
main disconnect, lockout and tagout power supply to
starter before working on the electric motor.
