Chapter 3 OPERATION
Test Operation
To conduct a test operation, follow the procedures below.
Before starting the engine, switch the water heater ON (automatic mode) and keep the coolant temperature prop-
erly. (Emergency generator with water heater)
Note: For engine operation, refer to
"Normal Engine Operation" (3-8)
.
Starting and Stopping
1.
Start the engine.
2.
Operate the engine at low idling speed under no load for 5 to 10 minutes for a warm-up operation.
3.
Stop the engine.
Inspection
1.
Leave the engine be stopped for about 30 minutes.
2.
During this period, check the engine and surrounding area for leaks of fuel, engine oil or coolant.
3.
At 30 minutes after the engine stop, check the oil level with the oil level gauge.
4.
If the oil level is low, add engine oil from the oil filler. Be sure to use the engine oil of the same brand and type.
5.
Open the radiator cap and check the coolant level.
6.
If the coolant level is low, add coolant to the specified level.
If a reserve tank is equipped, fill the reserve tank with coolant up to the "FULL" level line.
Always switch the water heater ON (automatic mode) through a whole year.
If the switch is not ON (automatic mode), each cylinder varies considerably in combustion at the starting up the
engine. Unburned fuel may explode in the exhaust pipe. (Emergency generator with water heater)
Remove the radiator cap only after the engine has cooled to room temperature. Place a waste cloth over the cap,
and loosen the cap about a half-turn to release internal pressure. Opening the radiator cap of coolant expansion
tank while the engine is hot causes steam and hot coolant to blow out and can result in skin burns.
Always use the coolant having the same concentration.
