3 Maintenance

3.3.1 Inspecting the motor seal

Do a leakage check of the sight glass/evacuation

hole of each motor.

If any oil is available on the sight glass or if any

oil has been spilled out from the evacuation hole,

replacement of the motor is recommended.

If oil is present in the evacuation it is an indication

that the primary seal of the motor is leaking. A

secondary seal after the evacuation is keeping

the oil out from the motor, but it is still recommen-

ded to replace the motor at a suitable timing if oil

is present in the evacuation.
