When running the engine for the first time, the tube oil flows to the piping thus reducing the
amount of oil in the crankcase. After running the engine for several minutes, stop it for 2-3
minutes.
Recheck the oil level.
2) Lube oil to the reduction and reversing gear case
For the checking of the amount of tube oil to the reduction and reversing gear case, check
with screwing the dipstick.

Important!
The tube oil for reduction and reversing gear is different from engine tube
