General information
WARNING
Risk of explosion due to hot gear unit surfaces caused by loss of oil.
Fatal or serious injuries.
•
Check the transportation packaging for oil residues. Oil residues could indicate
an oil leak. In this case, the lubrication of the gear unit is not guaranteed. This
could cause excessive temperature on the surface.
•
Contact SEW‑EURODRIVE if there are oil residues on the gear unit.
CAUTION
Risk of injury due to protruding gear unit parts.
Minor injuries.
•
Keep a sufficient safety distance to the gear unit/gearmotor.
CAUTION
Health risk due to dangerous gases, vapors, and residue created by heating fluoro-
carbon rubber to > 200 °C.
Damage to health.
The following gear unit components may contain fluorocarbon rubber: Oil seals,
breather valves, screw plugs.
•
Make sure that components made of fluorocarbon rubber are not exposed to
temperatures > 200 °C. Remove the components, if necessary.
•
Avoid inhaling fluorocarbon rubber gases and vapors as well as skin and eye
contact.
•
Avoid contact with the cooled-down fluorocarbon rubber, as dangerous residue
were formed while it was heated.
NOTICE
The bearing and the sealing rings can be damaged if exposed to solvents.
Damage to property.
•
When cleaning the shafts and flange surfaces with solvents, protect bearings and
oil seals.
•
Use a commercially available solvent.
INFORMATION
The assembly of gear head units with motors or adapters may be performed by au-
thorized personnel only. Contact SEW‑EURODRIVE.
