9.2 Oil level check

The oil level can be checked by the oil level indicator (see lubrication devices 8.4 and 8.5)

9.3 Oil check

Before checking the oil, the main electrical supply must be disconnected
Wait for the unit to cool to prevent burns!
Collect an oil sample at the oil drain.
Check oil condition and viscosity
If the oil is contaminated, change the oil even if the intervals according to 8.2.4 are not due.
Dispose of the oil sample according to environmental protection instructions.

9.4 Oil change

First, the main electrical supply must be disconnected.
Wait for the unit to cool to prevent burns!!
Change oil with the gear still warm, as this is beneficial for draining.
Place a collector under the oil drain.
Remove the oil level indicator, any breather plug, breathing valve and oil drain screw.
Drain oil completely.
Replace the oil drain plug and fasten it.
Fill with new oil according to the oil recommendations. In case you wish to use another oil
type, please contact Sumitomo Cyclo Europe.
For oil quantities, see 8.2.3 "oil quantities".
Check oil level at the indicator.
Fasten oil breather.
Dispose of the oil according to environmental protection instructions.

10. Troubleshooting

Operating problem
Unusual, constant running noise
Unusual, not constant running
noise
Oil leakage 1)
- from the gear cover
- from the motor flange
- from the motor shaft sealing
- from the gear flange
- from the output flange seal ring
Oil leakage from the breather
Slow speed shaft does not rotate
while motor is running or high
speed shaft is rotating

Possible reasons
1. Meshing/grinding noise:
bearing damage
2. Knocking noise:
irregularity in the reducer
Foreign substance in the oil
1. Sealing at gear cover not func-
tioning properly
2. Sealing damaged
3. Gear not vented
Oil level too high
- Incorect mounting position
- Repeated cold start (oil foams)
and / or oil level too high
Shaft to collar connection inter-
rupted
Issue: 09/2006
Trouble shooting
1. Check oil (see inspection and
maintenance) replace bearing
2. Contact customer service
Check oil (see 9.)
Stop drive, contact customer
service
1. Tighten gear cover screws and
observe the unit. If leakage
continues, contact customer
service
2. Contact customer service
3. Check oil breather
Adjust oil level (see 9.2)
Check breather and oil level
(see 9.2)
