Inspection and maintenance
Do not mix synthetic lubricants with each other nor with mineral lubricants!
Oil is the standard lubricant.
The position of the oil level plug, oil drain plug and the breather valve is depen-
dent on the mounting position. The respective position can be determined in the
mounting position diagrams (see section 8).
Checking the oil
level
1. De-energize the drive and secure against unintentional switch-on!
Wait until the gear unit has cooled down – Danger of burns!
2. For modified mounting positions, refer to Section 3.3!
3. For gear units with oil level plug:
– remove oil level plug, check fill level and correct if necessary
– install oil level plug
Checking the oil
1. De-energize the drive and secure against unintentional switch-on!
Wait until the gear unit has cooled down – Danger of burns!
2. Remove some oil from the oil drain plug.
3. Check the oil consistency
– viscosity
– if the oil is visibly contaminated, it is recommended to change it sooner than
recommended by the maintenance intervals under point 6.1.
4. For gear units with an oil level plug:
– remove oil level plug, check fill level and correct if necessary
– install oil level plug
Changing the oil
Only change the oil when the gear unit is at operating temperature.
1. De-energize the drive and secure against unintentional switch-on!
Wait until the gear unit has cooled down – Danger of burns!
Note: Gear unit must still be warm, otherwise the high viscosity of excessively cold
oil will make it harder to drain the oil correctly.
2. Place a container underneath the oil drain plug
3. Remove oil level plug, breather plug/valve and oil drain plug
4. Drain oil completely
5. Install oil drain plug
6. Fill new oil of the same type through the breather hole, otherwise consult our service
department
– amount in accordance with the mounting position (see section 8) or data on
nameplate
– check at the oil level plug
7. Install oil level plug
8. Install breather plug/valve
