Water and sediment in the fuel tank are removed via
the drainage plug in the bottom of the fuel tank.
Be very careful during draining. Do not drop
the plug or else all the fuel will flow out.
Drainage should be performed when the roller has been
standing for a long period of time, for example over-
night. The fuel level should be as low as possible.
The roller should preferably have been standing with
this side somewhat lower, so that water and sediment
will gather near the drainage plug (1). Drain as follows:
Place a container under the plug (1).
Undo the plug and drain off the water and sediment until
only clean diesel fuel appears through the plug opening.
Refit the plug.
Replace the main filter (3) of the air cleaner even if it
has not yet been cleaned five times, see under 50
hours for filter replacement.
If a clogged filter is not replaced the exhaust
fumes will be black and the engine will loose
power. There will also be danger of severe
damage to the engine.
Never work under the roller with the engi-
ne running. Park on a level surface and
block the wheels securely.
Wipe clean and remove the level/filler plug (1) and all
three drain plugs (2) and drain the oil into a suitable
receptacle. The volume is almost 12 litres (12.7 qts).
Save the oil and deposit it in an approved
manner.
Refit the drainage plugs and top up with fresh oil until
the correct level is reached. Refit the oil-level/filler plug.
Use transmission oil, see the lubrication specification.
