For installation, please ensure the center line of engine crankshaft and input shaft axis of
transmission (transmission box, gearbox or generator) are coaxial. And make sure the crankshaft is
not subjected to additional axial force caused by assembly.
17 Preparation before Starting Engine
(1) Check coolant level
If the engine is already installed on a vehicle or platform, you can check the coolant level
through the glass window on expansion water tank at any time, if the coolant is insufficient,
open the filler cap to add coolant. When open a filler cap with pressure relief valve and exhaust
button, be sure to press down exhaust button in advance if the engine is in hot state. Avoid
filling plenty of coolant when the engine is hot, otherwise some parts may be damaged due to
sharp temperature reduction. In an extraordinary situation, if there is no coolant in the engine, it
is allowed to add not too cold water slowly until the water overflows. Start the engine, run the
engine at 1000r/min and keep adding coolant until level gets stable, finally close the filler cap.
(2) Check fuel level
If the engine is already installed on a vehicle, turn on power switch, check the fuel level gauge
