Unscrew the level and drain plugs, fill the gear unit with oil and when it flows out of the level hole, retighten the plugs.
•
Turn the gear unit a few times to get rid of any air pockets then check the levels again.
EXPANSION TANK
Follow the steps below for applications with expansion tank: (see Fig. 25).
•
Remove plug “A”
•
To help air the gear unit (only during filling), one of the plugs on the top of the unit can be removed.
•
As the oil reaches the top of the open plug in the top part of the gear unit, replace the plug.
•
Keep filling until the oil reaches the min. visual level plug on the tank (fill to just above this level).
•
Replace the plug.
•
Never fill as far as the max visual oil level to leave room for the hot oil to expand.

Turn the gear unit a few times to get rid of any air pockets then check the levels again.

In some configurations, the retaining rings or accessories need to be lubricated separately with grease. This can be done using
the grease guns on the gear unit casing (see Fig. 26). This should be repeated on a regular basis. When lubricating is done au-
tomatically, a breather plug should be fitted to prevent any excess pressure from building up in the separate grease lubrication
chamber.
IMPORTANT:
CHECK THAT THE EXPANSION TANK IS INSTALLED HIGHER THAN THE TOP PART OF THE GEAR UNIT.
