Measures to be taken prior to assembly
CAUTION
Risk of injury due to chemical substances
Observe the manufacturer’s guidelines on how to handle lubricants and solvents.
Wear suitable protective clothing.
Improper use can damage the gear unit. Be sure to take the following precautions:
• Use a suitable cleaning agent to remove the corrosion protection from the hollow shaft and
the machine shaft.
• Inspect the hollow and machine shafts for damaged seats and edges.
• If necessary, rework the components with an appropriate tool and then clean them again.
• Apply an appropriate lubricant to the contact surfaces to protect them against fretting
corrosion.
NOTICE
Risk of damage to shaft sealing rings
Aggressive chemical cleaning agents may cause damage to shaft sealing rings.
Do not allow the cleaning agent to come into contact with the shaft-sealing rings.

NOTICE
Damage to the gear unit
The gear unit can become damaged if it skews during assembly.
When mounting the gear unit, make sure that the hollow shaft and machine shaft are aligned
and ensure that the machine shaft splines and hollow shaft splines match up. You can identify
the correct spline position by rotating the input shaft or gently swivelling the gear unit on the
hollow shaft.
