CAUTION
Risk of chemical burns due to chemical substances
There is a risk of chemical burns when handling corrosive cleaning agents.
Please observe the manufacturer's guidelines on how to handle cleaning agents and
solvents. Wear suitable protective equipment (gloves, safety goggles). Please use binding
agents to immediately clear up any spilt solvent.
CAUTION
Risk of injury due to chemically aggressive operating materials
There is a risk of injury to eyes and hands when handling chemically aggressive operating
materials.
Please observe the safety instructions in the data sheets of the oil used. Wear suitable
protective equipment (gloves, safety goggles). Remove any spilt oil immediately with an
oil-binding agent.
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 shaft and machine shaft 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 from cleaning agent
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.
