Engine lubrication
Oil level
Check the oil level in the engine sump
daily with a dipstick. The level should be
between the two notches cut into the dip-
stick and should never be allowed to drop
below the lower notch.
Caution:
Do not add so much engine oil that the
oil level rises above the max. marking
on the dipstick. Overfilling will result in
damage to the engine.
The oil level should be checked with the
engine horizontal and only after it has
been shut down for about 20 minutes.
Oil drainage
With the engine at operating temperature,
remove the oil drain plugs on the oil sump
and the oil filter bowl and allow the old oil
to drain off completely. Use a vessel of
sufficient size to ensure that the oil does
not overflow. Refit the oil drain plugs with
new gaskets.
Caution:
The oil is hot- risk of scalding. Do not
touch the oil drain plug with bare fin-
gers. Oil is an environmental hazard.
Handle it with care!
Refilling with oil
Refill with fresh engine oil at the oil filler
neck.

After refilling with oil, rotate the engine
with the starter and move the shut-down
lever to “stop” at the same time until the
oil pressure warning light goes out and
the oil pressure gauge shows a pressure.
Then start the engine and allow it to run at
medium speed for a few minutes. Check
oil pressure and tightness of system.
Then shut down the engine. After about
20 minutes, check the oil level. The oil
level should now be at the upper notch of
the dipstick, but not higher.
Add any necessary oil to the upper dip-
stick mark. Do not overfill.
Lubricating oil filter
Cleaning of the lubricating oil is effected in
a full-flow oil filter with paper cartridges.
A bypass valve ensures continuity of oil
supply if the filter elements should be
clogged.
