Change the oil more often (after 25 hours of
operation or at least once a season) if the engine
has to operate under demanding conditions or if
the ambient temperature is high.
The engine oil may be very hot if it is
drained off directly after the engine is
shut off. So allow the engine to cool a
few minutes before draining the oil.
1. Oil drain pipe (metal):
Unscrew the oil drain plug at the end of the pipe.
Collect the oil in a collection vessel. Then take
the oil to a recycling station. Do not allow oil to
get on the V-belts.
2. Screw in the oil drain plug. Make sure that the
fibre gasket and the O-ring inside the plug are not
damaged and that they are in the correct place.
3. Remove the dipstick and fill up with new oil.
Oil capacity:
Comfort, President - 1.4 l
Pro16, Pro20 - Excellent - 1.7 l (incl. oil filter)
Oil type, summer (> 4ºC): SAE-30
(SAE 10W-30 can also be used. However, oil
consumption may increase somewhat if 10W-30 is
used. Therefore, check the oil level more regularly
if you use this type of oil).
Oil type, winter (< 4ºC): SAE 5W-30
(if this oil is not available, use SAE 10W-30).
Use oil without any additives.
Do not fill with too much oil. This can cause the
engine to overheat.
After filling up the oil, start the engine and idle for
30 seconds. Stop the engine. Wait for 30 seconds
and then check the oil level.
Check to see if there is any oil leakage. If
necessary, fill up the oil up to the “FULL“ mark.
ENGINE OIL (Royal)
Change the oil for the first time after 20 hours of
operation (or during the first month), and then after
every 100 hours of operation or once every 6
months.
Change oil when the engine is warm. Always use
a good grade of synthetic oil (service grade SF, SG
or SH).
The engine oil may be very hot if it is
drained off directly after the engine is
shut off. So allow the engine to cool a
few minutes before draining the oil.
Unscrew the oil drain plug at the end of the pipe
(fig. 13).
Collect the oil in a collection vessel. Then take
the oil to a recycling station. Do not allow oil to
get on the V-belts.
Screw in the oil drain plug. Make sure that the fibre
gasket and the O-ring inside the plug are not
damaged and that they are in the correct place.
Remove the dipstick and fill up with new oil up to
the “UPPER” mark.
Oil capacity:
Royal - 0.9 l (= oil quantity at change. In total the
engine holds 1.15 l).
Oil type for all seasons: SAE 10W-40.
For extremely low temperatures (< -20° C), use
SAE 5W-30.
Use oil without any additives.
Do not fill with too much oil. This can cause the
engine to overheat.
OIL FILTER – ENGINE
(Pro16 - Pro20 - Excellent)
Replace the oil filter after every 100 hours of
operation or once a season.
Before screwing the new filter, oil the filter gasket
with engine oil.
Screw the filter by hand, until the filter gasket
touches the filter attachment. Then tighten ½ to ¾
of a full turn (fig. 14).
Start the engine and idle to see if any leakage
occurs. Stop the engine. Check the oil level. If
necessary, fill up the oil up to the “FULL” mark.

Clean the foam pre-filter every 3 months or after
every 25 hours of operation, whichever comes
first.
Clean the paper filter insert once a year or after
every 100 hours of operation, whichever comes
first.
Royal:
Clean the air filter every 3 months or after every 50
hours of operation, whichever comes first.

the machine operates on dusty ground.
1. Remove the protective cover of the air filter (fig.
15 - 17).
2. Dismantle the paper filter insert and the foam
