Operation (cont’d)

3. Starting the Generator

After you have completed the pre-start checklist procedures, you are ready to start the

generator.

Start engine

Start the engine with the guard in place.

 Before starting, confirm there are no loads connected to the generator’s

outlets.

 Follow the instructions provided in your engine manual for starting the

engine.

Check output

voltage without

load

Check output voltage before connecting loads to the generator.

WARNING:

The generator must be run at the correct speed in order to produce the

proper electrical voltage and frequency. Failure to do so could result

in damage to equipment powered by the generator and possible injury

to the individual.

1. Allow running generator to warm up for five minutes. Do not connect

any loads.

2. Use portable voltage meter to check output voltage at the generator’s

outlets/receptacles.

3. Measured voltage should be within the following ranges:

a. 108-132 volts at 120V receptacle(s).

b. 216-264 volts at 240V receptacle(s).

If the output voltage is NOT within the specified range:

1) Adjust the engine speed if possible.

2) If that doesn’t work, re-verify that:

a) Your engine’s rated horsepower meets the minimum

requirement,

b) Your sheave ratio is correct, and

c) The belts (or couplings) are not loose (squeaking, visibly

slipping).

3) If you are still not able to achieve acceptable output voltage, there

is a problem with the engine or the generator. Refer to your

engine’s owner’s manual for troubleshooting. If it appears that the

generator itself is the problem, call NorthStar Product Support @

1-800-270-0810 for assistance.
