Material damage
Corrosion possible through leaving the gear unit open too long.
Close the gear unit airtightly at the latest one hour after opening.
Before re­starting the gear unit take the following measure:
– Replace the screw plug with the air filter or wet­air filter.
• Place the inspection and/or assembly cover with the seal on the housing.
• Screw in the fastening screws of the inspection and/or assembly cover and tighten them to the specified
tightening torque (see item 6.19).

Material damage
Risk of damage to the gear unit through inadequate lubrication through preservative agent and operating

oil must be drained off before initial start­up and the gear unit thoroughly flushed out with operating oil
(for this see item 10.2.2).
The flushing oil must not be used for operation of the unit.
