Fuel is flammable and explosive under certain con-
ditions and can cause severe burns. Be prepared
for fuel spillage; any spilled fuel must be completely
wiped up immediately. When the fuel hose is dis-
connected, fuel spills out from the hose and the
pipe because of residual pressure. Cover the hose

Fuel is extremely flammable and can be explosive
under certain conditions resulting in serious injury
or death. Do not try to start the engine with the fuel
Turn the engine stop switch run position.

without the fuel in the fuel tank. If the fuel pump is
driven without the fuel, it may be damaged.
Start the engine, and let it idle.
Measure the fuel pressure with the engine idling.
