7.1 Preliminary work regarding inspection and maintenance
Observe the following notes before you start with inspection/maintenance work.
WARNING
Risk of crushing if the drive starts up unintentionally.
Severe or fatal injuries.
• Work on the gear unit only when the machine is not in use. Secure the drive unit
against unintentional power-up. Attach an information sign near the ON switch to
warn that the gear unit is being worked on.
WARNING
An operator machine that is not appropriately secured can fall down during gear unit
installation or removal.
Severe or fatal injuries.
• Protect the operator's machine against unintentional movement when installing or
removing the gear unit.
• Before releasing shaft connections, make sure that there are no active torsional
moments present (tensions within the system).
WARNING
Danger due to using impermissible gear unit oil.
Severe or fatal injuries.
• Only use food-grade oils when the gear unit is used in the food industry.
WARNING
Risk of burns due to hot gear unit and hot gear unit oil.
Serious injury.
• Let the gear unit cool down before you start working on it.
• Remove the oil drain plug very carefully.
CAUTION
Danger due to lubricant leaking from damaged seals and the breather.
Minor injuries.
• Check the gear unit and mount-on components for leaking lubricant.
• The seals must not come in contact with cleaning agent as this may damage the
seals.
• Protect the breather against damage.
• Make sure that there is not too much oil in the gear unit. If the oil level is too high
and the temperature rises, lubricant may escape from the breather.
