DANGER
Risk of injury
There is a danger of injury due to rapidly rotating drive and driven elements.
• Drive and driven elements, such as belt drives, chain drives, shrink disks, fans and couplings must be fitted
with contact protection.
• The drive unit must be secured against accidental start-up while the cover caps are removed.
NOTICE!
Gear unit damage
The separate manufacturer’s documentation for the hub must be observed for installation
NOTICE! Gear unit damage
Incorrect application of transverse forces may cause damage to the gear unit.
• The transverse force must be applied to the gear unit as closely as

• Do not subject the gear unit to harmful axial forces when fitting the hubs. In particular, do not hit the hubs with
a hammer.
