Oil type, summer (> 4ºC): SAE-30

(SAE 10W-30 can also be used. However, oil con- sumption 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 neces- sary, 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 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 dam- aged 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)

Replace the oil filter after every 100 hours of oper- ation 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 oc- curs. Stop the engine. Check the oil level. If neces- sary, fill up the oil up to the “FULL” mark.
