Injury to persons
Transport damage may cause malfunctions of the gear unit, which may cause material damage or personal
injury.
• Please inspect the delivery for transport and packaging damage immediately on receipt. Report any damage
to the carrier immediately. Gear units with transport damage must not be commissioned.
• Risk of injury due to sharp edges and corners on the tensioning belts and by tensioning belts which spring
back when they are cut.
• The drive unit must be inspected and may only be installed if no leaks are apparent. In particular the shaft
sealing rings and sealing caps must be inspected for damage.
• Pay attention to leaked lubricants, they may cause slips.
All bare metal surfaces and shafts of the geared motor are protected against corrosion with oil, grease
or corrosion protection agents before shipping.
Thoroughly remove all oil / grease or corrosion protection agents and any dirt from the shafts and
flange surfaces before assembly.
Oil filling
Gear units and geared motors are not filled with oil as standard when delivered from the factory. For filling,
details of the type and quantity of lubricating oil must be obtained from the type plate (3.5 "Checking the type
plate data").
The quantity of lubricating oil which is stated in Section 7.3.3 "Lubricant quantities"should be regarded as a
guide value and may vary according to the speed ratio. The value which is stated on the type plate is specific to
the order and is therefore more precise.
As an option, the gear unit can be filled with lubricant. In all cases, the oil level must be checked as per Section
5.2.6 "Oil level"prior to commissioning.
In applications where an incorrect rotational direction may result in damage or potential risk, the
correct rotational direction of the output shaft must be established by test running the drive when
uncoupled and ensured for subsequent operation.
Oil level tanks (Option: OT) are fitted as standard prior to delivery of the gear unit. If this is not the
case, the intended position can be obtained from the order-related dimension sheet.
Gears with integrated return stops are marked with arrows on the drive/driven sides. The arrows point
in the rotation direction of the gear unit. When connecting the motor and during motor control, it must
be ensured that the gear unit can only operate in the correct direction of rotation.
If possible, the shaft sealing rings or the gear unit should be protected from exposure to direct
sunlight.
