4.4.1.1 Represerving the interior of the gear unit (main gear unit) in case of longer periods of storage
CAUTION
Risk of injury
Risk of injury to eyes or hands through chemically aggressive operating media.
Wear suitable protective glasses and protective gloves.
Remove any oil spillage immediately with a binding agent.
For storage periods longer than 24 months (see table 3), renew the preservation in the interior of the gear
unit. The following procedure is recommended:
•
Unscrew the air filter or wetair filter (1) on the oilequalising tank (see fig. 4 or fig. 5).
•
Place a suitable container under the oildrain points (4 and 5) of the gearunit housing.
•
Open the oildrain cock (4) and unscrew the residualoil drain plug (5) and drain the used preservative
oil into a suitable container.
•
Dispose of the residue of the preservative oil in accordance with regulations.
•
Shut the oildrain cock (4) and screw in the residualoil drain plug (5).
•
Fill the gear unit with "Castrol Alpha SP 220 S".
Determine the filling quantity according to the gearunit dimensions: length x width x height x 0.05.
NOTICE
Material damage
Corrosion possible through use of an unsuitable preservative agent.
Use special oil "Castrol Alpha SP 220 S" with additional anticorrosive agent (additive "S").
•
Screw in the air filter or wetair filter (1).
•
Replace the air filter or wetair filter (1) with the screw plug.
NOTICE
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.
The gear unit has thus been preserved for another period of 24 months.
NOTICE
Material damage
Risk of damage to the gear unit through inadequate lubrication through preservative agent and operating
oil being mixed up.
The use of synthetic oil is not permissible.
