6. PRE-OPERATION CHECK

Before starting, complete the following:

1.Set the generator's Start/stop switch to the Stop position.

2.Turn OFF the utility power supply to the transfer switch using the means provided (such as the utility main line circuit breaker).

3.Check the engine crankcase oil level and, if necessary, fill to the dipstick FULL mark with the recommended oil. Do not fill above the FULL mark.

4.Check the fuel supply. All fuel shutoff valves in the fuel supply lines must be open.

Never operate the engine with the oil level below the “Add” mark on the dipstick. Doing this could damage the engine.

6.1. Electrical Checks.

Complete electrical checks as follows:

1.Turn on the utility power supply to the transfer switch using the means provided (such as a utility main line circuit breaker).

The transfer switch is now electrically “hot.” Contact with “hot” parts will result in extremely hazardous and possibly fatal electrical shock. Proceed with caution.

2.Use an accurate AC voltmeter to check utility power source voltage across terminals.

the generator’s main circuit breaker to its ON (or closed) position.

Proceed with caution! Generator power voltage is now supplied to the transfer switch. Contact with live transfer switch parts will result in dangerous and possibly fatal electrical shock.

8.Connect an accurate AC voltmeter and an AC frequency meter across transfer switch terminal lugs and voltage and frequency of the unit must be accord to the specifications of the generator.

9.Connect the AC voltmeter test leads across terminal Lugs and neutral, one by one.

10.Set the generator’s main circuit breaker to its OFF (or open) position. Let the engine run at no load for a few min- utes to stabilize internal engine generator temperatures.

11.Set the generator's Start/stop switch to stop position. The engine should shut down.

NOTE:

It is important that you DO NOT proceed until you are cer- tain that generator AC voltage and frequency are correct and within the stated limits. Generally, if both AC frequency and voltage are high or low, the engine governor requires adjustment. If frequency is correct, but voltage is high or low, the generator’s voltage regulator requires adjustment.

6.2. GENERATOR TESTS UNDER LOAD

To test the generator set with electrical loads applied, pro- ceed as follows:

1.Set generator’s main circuit breaker to its OFF (or open) position.

2.Set the generator's Start/stop switch to OFF.

3. Check utility power source voltage across terminals and
