EVERY 2000 HOURS OF OPERATION (YEARLY)
Before changing the oil it is important that the
roller has been run long enough for the oil to
be warm and easy flowing before being drai-
ned. Any contamination will thus also flow out
with the oil. Observe cleanliness and
remember that the roller is to be level.
Applies to D & PD only:
Place the roller on a level surface so that the drain/level
plug is straight down.
Wipe clean round the plugs.
Place a receptacle under the drain plug (2) and drain off
the oil. The receptacle is to hold about 5 litre (5.3 qts).
Also remove the filler plug (1).
Run the roller back so that the filler plug is at its highest
position.
Fill with oil until the level reaches the level plug hole.
Use transmission oil according to the lubricant
specification.
The plugs are magnetic and any metal particles must
be wiped off before refitting.
