ATTENTION
Never run the engine for more than 10 seconds out of the water.
Overheating could severely damage the engine and the exhaust system.
Idle running!
3.2 Checking of oil level
Oil level check:
Check oil level before every ride.
Change oil during 1st inspection after 12 h.
Change oil every 25 h, but at least once every year. Use only Hydrospace
oil. Otherwise, we cannot recognize warranty claims.
ATTENTION
Measure oil level always when the S4 Standup is in the horizontal
position (operating condition). The engine has to be COLD for this.
Just check it after a short start of 5 seconds.
