MAINTENANCE
For gear units, first oil change should be after about 300 hour (run-in period).
Never mix the synthetic oil and mineral oil together.
Every 3000 working time, at least every 6 months, you have to check the oil and oil level, the
seals visually for leakage. For IEC input gear units, the elastomer should be tested or replaced
if necessary.
Dependong on the operating conditions every 3 years at the latest for inspection is needed.
Then change the mineral oil and replace the bearing grease.
Depending on the operating conditions, change the oil seals.
Verify that the coupling used to connect the motor is always greased to avoid risks of wear.
