1.6.3 Hazards due to high or low temperatures
The gear unit may heat up to 90 °C during operation. Touching hot surfaces or contact with hot oil may
result in burns. At very low ambient temperatures freezing may occur on contact.
• Only touch the gear unit when wearing gloves after operation or at very low ambient temperatures.
• Before starting maintenance work, allow the gear unit to cool down sufficiently after operation.
• Provide a contact guard if there is a risk that persons may touch the gear unit when it is in
operation.
• Bursts of hot oil mist may be emitted from the pressure vent screw during operation. Provide a
suitable guard so that persons cannot be injured by this.
• Do not place any flammable materials on the gear unit.

1.6.4 Hazards due to lubricants and other substances
Chemical substances which are used with the gear unit may be toxic. Eye injuries may result if these
substances enter the eyes. Lubricants and adhesives may cause skin irritation.
Oil mist may escape when vent screws are opened.
Due to lubricants and conservation materials, gear units may be slippery and slip out of the hands.
There is a slipping hazard from spilled lubricants.
• When working with chemical substances wear chemical-resistant gloves and work clothing. Wash
your hands after working.
• Wear protective goggles if there is a possibility of splashed chemicals, for example when filling oil
or during cleaning work.
• If chemicals enter the eyes, rinse with large amounts of cold water immediately. Consult a
physician in case of symptoms.
• Observe the safety data sheets for the chemicals. Keep the safety data sheets in the vicinity of the
gear unit.
• Collect spilled lubricants immediately with a binding agent.

The cooling system is under high pressure. Damage or opening a cooling line which is under pressure
may result in injury. Depressurise the cooling circuit before working on the gear unit.
