7.3.1 Check/top-up
Procedure:
• Position the machine on a level
surface for the check.
• Wipe around the dipstick. Unscrew it and
pull it out. Clean the dipstick (fig.10.H).
• Push the dipstick down completely
without screwing it into place.
• Now pull the dipstick up again.
Read off the oil level.
• Top up using the oil extension hose (fig.3.E) if
the level is lower than the "MAX" mark (fig.12)
• For the correct replacement
procedure, see par. 7.3.2
Do not overfill as this could cause
the engine to overheat. If the oil level
exceeds the "MAX" mark, the oil must be
drained until the correct level is achieved.
NOTE For the type of oil to use,
see the "Technical Data Table".
7.3.2 Replacement
The oil may be very hot if removed
just after the engine has been switched
off. Consequently allow the engine to
cool down for a few minutes before
proceeding to drain off the oil.
Replace the engine oil based on the frequency
indicated in the "Maintenance Table". Change
the oil more frequently if the engine has
to operate in demanding conditions.
Proceed as follows:
1. Place the machine on a flat surface.
2. Place a suitable container
under the drain plug.
3. Remove the top-up cap (fig. 10.H)
4. Remove the drain cap (fig. 10.I)
5. Collect the oil in a suitable vessel.
6. Screw the oil drain plug back in.
7. Clean up any spills.
8. Fill with fresh oil. For the quantity of oil to
use, see the "Technical data table".
9. After filling up the oil, start the engine
and leave it to idle for 30 seconds.
10. Check there are no oil leaks.
11. Stop the engine. Wait 30 seconds and
check the oil level again. If necessary,
also see "check/top-up" (par. 7.3.1).
IMPORTANT Hand the spent
oil over to a disposal facility in
accordance with local provisions.
