North Star 27500 owner manual Installation, Load Application

NEVER operate the generator while wearing loose fitting clothing such as neckties, scarves or untucked shirts.

NEVER operate the generator, or handle any electrical equipment while standing in water, while barefoot, while hands are wet or while in the rain or snow. Electric shock may result.

NEVER operate the generator under the following conditions:

A. Excessive change in engine speed, slow or fast.

B.Overheating in load connecting devices.

C.Sparking or arcs from generator.

D.Loss of electrical output.

E.Damaged receptacles.

F.Engine misfire.

G.Excessive vibration.

H.Enclosed compartments, or confined areas.

I.Flame or smoke.

J.Rain, snow or wet conditions.

K.Operator non-attendance.

L.Without proper guarding in place.

WARNING Keep fire extinguisher close by your generator and be familiar with how to use it. Consult your local fire department for correct extinguisher type.

DANGER Remember, exhaust fumes are deadly carbon monoxide, a poisonous gas and must be vented to the outside where there are no people. Cooling air of sufficient amounts must be brought in and exhausted out to ensure proper cooling of the engine and generator.

INSTALLATION

Choose a location where the generator will not be exposed to rain, snow or direct sunlight. Common places for mounting your PTO generator are to a trailer or a cement slab. However you choose to mount the generator, make sure it can get as close to the load as possible. This will make using the generator more convenient and reduce voltage drop.

The installation site must be free from water, moisture, or dust. Foreign matters, such as dust, dirt, sand, lint, or abrasive materials can cause damage if

allowed inside the generator. All electrical components should be protected from excessive moisture or the insulation system will deteriorate and result in grounding or shorting out of the generating system.

Design the application to minimize the angle of the driveline, 15° maximum. The smaller the angle of operation, the longer the driveline will last.

When trailer mounting the generator select a trailer that is wide enough to withstand the torque of start-up and loading torque. Wheels that are not spaced properly could cause the trailer to tip over. The constant vibration of the generator can cause metal

fatigue of the trailer base if the steel used is not thick enough.

DANGER Trailer may tip over and cause serious injury or death. Never stand near an operating PTO generator.

Use four, grade 5, 5/8” bolts to mount generator.

After the generator is firmly mounted , attach the PTO driveline to the generator then the tractor. Use a synchronized PTO driveline rated at 48 HP minimum.

DANGER Never attach PTO driveline while tractor is running.

DANGER Always have proper guarding of rotating parts. Failure to guard the power transmission mechanisms may result in serious injury or death.

While seated on the tractor and the engine at idle, engage the PTO. Slowly increase the throttle until00506the needle in the generator voltmeter is at or above the black line in the green area. A load can now be applied to the generator. Remember to stay clear of the rotating PTO driveline. From the tractor seat re- adjust the speed until the needle on the generator voltmeter is close to the black line in the green area. If the needle will not rise to the green area no matter what the engine speed, the generator is either overloaded or there is a problem. Use the troubleshooting guide at the end of the manual for assistance with possible problems.

Before each use check the gear box oil level. Use 80W-90 SAE synthetic gear oil and fill to the middle of the oil level sight plug.

LOAD APPLICATION

It is important to determine the total electrical load before it is connected to the generator. The two major factors in determining the life of a generator head are: heat build up, caused by overloading the generator and corrosive contaminants, that attack the wiring insulation. If the generator is overloaded, the wires
