(3) Coolant Change
The coolant must be changed at intervals of six months.
If the coolant is being fouled greatly, it will lead to engine
overheat or coolant blow-off from the radiator.
Coolant draining
1) Remove the radiator cap.
Open the drain cock at the radiator lower part to drain the
coolant in the radiator.
CAUTION: When removing the radiator filler cap while the engine is
still hot, covbr the cap with a rag, then turn it slowly to
release the internal steam pressure. This will prevent a
person from scalding with hot steam spouted out from
the filler port.
2) Drain away the coolant from the engine by loosening the water
drain plug at the rear of generator on the left side of cylinder
body.
