Arrange a receptacle to collect the oil. The receptacle
should hold at least 100 litre (26.5 gal).
An empty oil barrel or similar vessel at the side of the
roller would be suitable. Allow the fluid to run from the
drain tap (1) through a hose to the oil barrel.
Fill with fresh hydraulic fluid according to instructions
under the heading “Hydraulic reservoir – checking the
level”. Change all the hydraulic filters. See under the
heading “Hydraulic system – changing the filters”.
Ensure that ventilation (extraction) is
adequate if the engine is run indoors. (Risk
of carbon monoxide poisoning).
Check the level and top up as required.

Never work underneath the roller when the
engine is running. Park on a level surface.
Chock the drum and wheels if necessary.
Unscrew the drain plug (3) and drain off the oil.
Refit the plug.
Remove the level plug (2) and fill with fresh gearbox oil
through the filler plug (1). Fill slowly so that the oil level
has time to even out.
Refit the plugs (1) and (2) when the level is correct.

straight up. Place a receptacle that will hold 5 litre
under the level/drain plug (2).
Unscrew the filler plug (1). Unscrew the drain plug (2)
(large plug with 24-mm (0.945 in) wrench size).
Allow all the oil to run out. Then unscrew the level plug
(13-mm (0.512 in) wrench size) from the drain plug (2).
Fit the drain plug with level pipe in the cassette. Fill with
fresh synthetic oil according to instructions under the
heading “Drum cassette – checking the oil level”.
Clean the magnetic filler plug (1) from any metal
particles before refitting it.
