WARNING

READ and UNDERSTAND this manual completely before using the generator! Failure to properly set up, operate, and maintain this generator could result in serious injury or death from carbon monoxide poisoning, electric shock, entanglement, fire, or burns . In addition, an improperly secured generator can lift or flip and cause severe injury . In particular, be aware of the following hazards:

CO Poisoning

The running engine gives off carbon monoxide, a poisonous gas that can kill you. You CANNOT smell it, see it, or taste it.

•

ONLY run generator-engine assembly OUTDOORS and AWAY from building air intakes. NEVER run inside any enclosed or semienclosed spaces, including homes, basements, garages, sheds, and boxes. These spaces can trap poisonous gases, EVEN if you run a fan or open windows.

•

Install carbon monoxide alarms inside nearby structures/buildings (battery-operated, or plug-in with battery backup).

Electric shock / Electrocution

•

High voltage electricity from generator can kill. DO NOT operate in wet locations. Be sure generator is properly grounded. Use only ULlisted, outdoor-rated grounded GFCI-equipped extension cords of proper size.

• NEVER plug the generator directly into a wall outlet. ANY connection to a building’s electrical system MUST ISOLATE THE

GENERATOR FROM UTILITY POWER via a UL-approved transfer switch installed by a licensed electrician. Otherwise, back feed from the generator into the power grid could kill utility workers.

Fire

•

DO NOT overload generator (per rated capacity), and OPERATE ONLY in an area with adequate cooling ventilation so generator does not overheat and possibly cause fire. Keep all objects at least 7’ from generator vent openings. Refer to engine owner’s manual for minimum safe clearance distance between hot engine exhaust and nearby combustible materials/structures.

•

ALWAYS keep a fire extinguisher rated “ABC” nearby.

Entanglement / Moving Object Impact

•

Never operate the generator without proper guarding of the power transmission assembly, including all rotating shafts, pulleys, belts, and

• couplings. Clothing or hair can become rapidly entangled in unguarded rotating parts, resulting in serious injury or death.

Failure to properly mount and secure the generator may cause the unit to lift or flip during use, which could result in severe injury to the operator or bystanders, or cause damage to surrounding objects.

Power Load Planning & Management

WARNING

NEVER exceed the rated wattage capacity of your generator.

OVERLOADING may cause SERIOUS DAMAGE to the generator and attached electrical devices, and may result in fire.

Your generator MUST BE SIZED PROPERLY to provide both the running and starting (surge) wattage of the devices you will be powering. Before using your generator, determine the running and starting wattage requirements of all the electrical devices you will be powering simultaneously.

The sum of the running and starting wattages of the devices being powered must not exceed the continuous output rating of your generator. (The continuous output rating of your generator is listed in the “Specifications” section of this manual.) Note that:

•

Devices without electric motors such as light bulbs, radios, and televisions have the same running and starting wattage.

•

Devices with electric motors such as refrigerators, compressors, and hand tools typically require a starting wattage that is 3 to 5 times greater than the running wattage.

The running and starting wattage requirements are often listed on a device’s nameplate. If wattage is not given on the device’s nameplate, the wattage may be calculated by multiplying the nameplate voltage by nameplate amperage, Watts = Volts X Amps.

Example conversion to watts:

120 Volts X 5 Amps = 600 Watts

If only the running voltage is given on the nameplate for a device with an electric motor, the starting wattage can be approximated to be three to five times the running wattage.

Estimates for the running wattage requirements for common devices are listed in Table 4 below.

Guidance for starting wattages is provided in the table’s footnotes.

(b) For extremely hard to start loads such as air conditioners and air compressors, consult the equipment dealer to determine maximum wattage

To calculate the running and starting wattage requirements for the devices you will be powering, follow these steps:

1.

Make a list of all electrical devices you will be powering at the same time with the generator.

2.

List the greater of the running or starting wattage next to each device as obtained from the devices’ nameplate or

Table 4 . If only the running wattage for a device with an electric motor is known, the starting wattage can be estimated to be at least 3 times the running wattage.

3.

Add the wattages for all devices on your list. This total must be lower than the continuous output rating of your generator.

Example:

In this example, the generator must have a continuous output of at least 6275 W in order to power all of the devices simultaneously.

STAGGERING LOADS

You can increase the number of devices your generator can power by staggering the load on the generator. For example, you could alternately power your refrigerator and air conditioner for limited periods of time -- powering only one of the devices at a time and never powering both at the same time.

11

Installation / Initial Set-Up

There are a number of important steps required to set up your generator for initial use. These steps are:

Steps for Installation / Initial Set-Up

1.

Unpacking & delivery inspection.

2.

Planning the power load to stay within the generator’s rated capacity.

3.

Setting up for the type of power generation you need: a.

portable power source, or b.

connected to a building as a back-up power source.

4.

Selecting a site for using the generator.

5.

Mounting & connecting generator and engine.

6.

Grounding.

Each of these steps is discussed in detail below:

1. Unpacking & Delivery Inspection

1.

You should inspect the generator immediately after you receive delivery.

See the “Machine Component Identification” section of this manual for a diagram of the generator and its components.

• If you have missing or damaged components, contact Product Support at 1-800-270-0810.

2. Planning the Power Load

Plan your power load so that you do not exceed the generator’s rated capacity.

See the “Power Load Planning & Management” section of this manual to review how to plan and manage power loads for the generator.

3. Set-up either as a BUILDING BACK-UP or PORTABLE Power Source

This generator is designed to provide up to 9600W of continuous electrical power. It can supply electricity in two ways:

1.

As a back up, standby power source for a building. For this application, you must arrange for a licensed electrician to connect the generator to your building’s electrical system via the installation of an UL-approved transfer switch. The transfer switch must be installed in accordance with building electrical code and guidelines supplied by your power company.

12


2.

As a portable power source . You can plug appliances or tools directly into the generator’s electrical outlets.

Specific requirements for each are given below.

Note: Regardless of whether you use your generator as a back-up power source connected to a building or as a portable power source, you must not overload the generator. Overloading may cause serious damage to the generator and attached electrical devices.

Using as a

Back-up Power

Source for a

Building

Contact a licensed electrician to install an UL-approved transfer switch you want to use your generator as a back-up power source for a building.

What does a transfer switch do? It: a) Safely connects the generator to your building’s electrical system by isolating your generator from your utility company’s power lines,

AND b) Connects your generator to a critical subset of your building’s circuits that are needed for emergency power needs.

If your generator will be connected to your building’s electrical system, it

MUST ALWAYS be isolated from the utility power grid with a UL-approved transfer switch installed by a licensed electrician in compliance with all applicable building and electrical codes, and in accordance with guidelines supplied by your power company.

DANGER:

A transfer switch must be installed in order to isolate your generator from the utility power grid. If your generator is NOT properly isolated from the utility system, serious hazards will arise:

 When your generator is running, it’s output will back feed into the utility power line and transformer that are normally used to provide you with power. The transformer will step up the current to the normal line voltage. An unsuspecting utility line worker working on what he thinks is a deactivated line could be electrocuted.



If your generator is connected (running or not) when utility power is restored, your generator will be destroyed. It could also explode or cause fire.

In addition to isolating your generator from the utility system, the transfer switch connects your generator to a limited set of circuits in your building that have been chosen as critical to operate during a power outage.

This generator can power up to 9,600 watts, which may not power your entire home or farm outbuilding -- you must work with the installing electrician to determine which devices/appliances you wish to power during an outage.

The electrician can help you determine which circuits and devices can be

13 if


powered simultaneously without overloading the generator.

(See the previous section of this manual entitled “Power Load Planning &

Management” for more information on load application and selection.)

Using as a

Portable Power

Source

When using the generator as a portable power source, you can plug electric devices and appliances directly into the generator’s electrical outlets.

There are three different kinds of electrical outlets on the generator:

1.

One 120/240 Volt, 40 Amp straight-blade receptacle (NEMA 14-50R receptacle compatible with NEMA 14-50P mating plug). This receptacle has two 40 Amp circuit breakers to limit maximum current.

2.

One 120 Volt, 30 Amp locking receptacle (NEMA L5-30R locking receptacle compatible with L5-30P mating plug)

3.

Two 120 Volt, 20 Amp duplex straight-blade receptacles (NEMA 5-

20R duplex receptacles compatible with NEMA 5-20P or 5-15P mating plugs).

NEMA

14-50R

NEMA

L5-30R NEMA

5-20R

(See more technical detail about these receptacles and their associated circuit breakers in the “Machine Component Identification” section of this manual.)



Make sure you plug each electrical device/appliance into the correct generator outlet based on the device’s plug configuration and voltage/amperage rating. Never exceed the amperage rating of an outlet.



Extension cords may be used to power devices that are located at a distance from the generator. However, use only UL-listed, outdoor-rated, grounded extension cords of the proper size. Additionally, if using the generator in damp or highly electrical conductive areas or on construction

14


jobsites, always use ground fault circuit interrupter (GFCI)-equipped extension cords to prevent electrical shock. Use Table 5 below to choose an adequately sized extension cord according to the amperage of the device being used and the length of the cord.



All extension and appliance cords must be in good condition and not worn, bare, frayed, or otherwise damaged.

WARNING:

Use of damaged electric cords can cause electric shock or fire.

Note: If an extension cord becomes hot to the touch, it is overloaded or damaged and must be replaced.

Northern Tool is NOT responsible for damage or injury resulting from customer use of inadequate extension cords.

4. Select a Suitable Site

Before using the generator, you must select a suitable OUTDOOR location for installation and operation of your generator. The location should meet all the criteria listed below.

WARNING:

You must choose a suitable site for operating your generator to avoid equipment damage and/or injury and possible death from carbon monoxide poisoning, electric shock, or fire.

15


Choose a site that meets all of the criteria specified below.

Site/Location Criteria:

Dry, level surface The generator should be positioned on a dry, firm, level surface.

Ensure that the generator sits level and will not slide or shift during operation.

Outdoors only – dangerous carbon monoxide exhaust

DANGER: Carbon monoxide poisoning hazard

The exhaust from the engine contains carbon monoxide (CO), a poisonous gas that can kill. You cannot smell it, see it, or taste it.

Follow the directions below for choosing a location to operate your generator in order to avoid carbon monoxide poisoning.

The location you choose to operate the generator must be OUTDOORS and away from all air intakes :

• Never run the generator/engine assembly inside any closed or semienclosed spaces (even if outdoors), including homes, garages, basements, barns, sheds, or boxes. These spaces can trap poisonous gases, even if you run a fan or open windows.

• Place the generator so that the exhaust fumes from the engine will not be directed towards people or building air intakes.

• Ensure that working, battery-operated or battery back-up carbon monoxide alarms are used in any dwelling/structure that is in close proximity to the running generator.

• Note that this generator is NOT designed or approved for use in vehicles or marine applications. Never run the generator inside RVs or other vehicles, on boats, or on pick-up truck beds.

WARNING:

Never attempt to attach ductwork to the engine exhaust to allow for installation inside an enclosure. This could cause hot air deflection, heat build-up, and increased exhaust back-pressure, resulting in possible exhaust leakage or damage to the generator or engine.

Adequate cooling ventilation

The generator needs adequate, unobstructed flow of air to allow for proper cooling of generator head.

• Situate so there is adequate clearance around generator to allow for cooling airflow so that heat does not build up. Never block vent slots. The closest object should be at 7 feet away from vents.

16


•

•

•

Do not run the generator in close proximity to other heat-generating equipment, such as another generator. The combined heat that is generated may raise air temperature in the immediate area and there will not be adequate cooling ventilation.

Do not allow debris to accumulate and block airflow.

Do not operate with a tarp, blanket, or cover surrounding the generator.

Hot engine exhaust clearance

The exhaust gas from your engine is extremely hot and can cause combustible materials to catch on fire.

• Position engine exhaust at a safe distance from all nearby combustible materials and buildings/structures. Refer to your engine manual to determine the safe clearance distance required.

• Equip the engine with a spark arrestor if the generator will be used near any ignitable forest, brush, or grassy land. Make sure you comply with applicable local, state, and federal codes.

• Keep a fire extinguisher rated “ABC” nearby. Keep it properly charged and be familiar with its use.

No wet conditions Choose a location where the generator will NOT be exposed to rain, snow, or direct sunlight.

Exposure to water can cause electric shock.

You may operate the generator under an outdoor, canopy-like structure of heat-resistant material that is open on all sides. Make sure that all parts of canopy are:

• at least 7’ from generator

• at an adequate safe clearance from hot engine exhaust.

Allow for adequate clearance above generator so that heat from generator does not build up.

Away from dust/dirt

Hearing protection

Do not use the generator in extremely dusty or dirty conditions.

Excessive dust and dirt can cause premature failure of the machine.

Generators can produce noise levels of up to 95 dB in close proximity, which can be dangerous to human hearing with prolonged exposure.

(This is in addition to the noise produced by the engine.)

Hearing protection may be required for persons working within 15-20 feet of the running generator for an extended period of time.

WARNING:

Never attempt to attach ductwork to the engine exhaust to lower noise levels. This could cause hot air deflection, heat build-up, and increased exhaust back-pressure, resulting in possible exhaust leakage or damage to the generator or engine.

5. Mounting & Connecting Generator and Engine

You will need to supply a minimum 18 HP engine to power the generator.

There are two methods to connect the generator to the engine:

1.

The recommended method is to use sheaves (pulleys) and a V-belt(s) .

2.

An alternative method is to direct couple the generator to the engine. However this method requires great care to align the shafts of the generator and engine to within the specified tolerances of the chosen coupler.

In either case, the engine-generator assembly must be properly mounted & guarded . Note that the customer is responsible for obtaining and installing an appropriate guard.

Mounting:

The engine and generator must be mounted to a common base such as a heavy-duty metal plate. Secure mounting will ensure that the generator will not lift or flip during use. In addition, all engines vibrate and the generator must move with the engine to prevent excessive belt slippage or misalignment of couplings.

Guarding:

-The power transmission assembly must be equipped with a guard that prevents contact with all rotating shafts, pulleys, belts, and couplings . Clothing or hair can become rapidly entangled in unguarded rotating parts, resulting in serious injury or death.

-This guard is not supplied with the generator because the manufacturer does not know the dimensions of the engine to be used, nor in what configuration the customer will choose to mount the generator & engine.

Follow the detailed instructions below for mounting, connecting, and guarding the engine-generator assembly.

Mount to a common base

Mount the generator and engine to a common base such as a heavy-duty metal plate of at least ¼” thickness.

WARNING:

Failure to properly mount the generator may cause the unit to lift or flip during use, which could result in severe injury to the operator or bystanders, or cause damage to surrounding objects.

1.

Choose a mounting base that is of adequate size and strength to withstand operating torque and vibration without either flipping or experiencing stress failure. Plate should be at least ¼” thick.

18


2.

See below for a possible mounting configuration.

3.

If the control box is not located on the correct side for your application, you can rotate it to the opposite side:

1) Remove the fan vents.

2) Remove the four drive-end bracket bolts.

3) Rotate the drive-end bracket 180°.

4) Re-torque bolts to 17 ft-lb.

5) Reinstall the fan vents

6) Remove the four screws at the base of the control box and rotate the control box 180°.

7) Replace screws at base of the control box.

8) The voltmeter is now on the back of the machine instead of the front

19


Connect generator to engine

4. Bolt the generator to the mounting base using three, 7/16” grade 8 bolts. See below.

Mounting

Holes

Note: In order to access two of the mounting holes, you will need to remove the louvered, fan vent panels on both sides. ALWAYS replace panels before starting the generator.

If mounting to a concrete slab, use the optional mounting kit, NorthStar item

#165935 (available from Northern Tool & Equipment catalog or by calling

Product Support @ 1-800-270-0810). The kit comes with two mounting plates. a. Attach the two mounting plates to the generator using the three, grade 8,

7/16” bolts provided in the kit. b. Mount the plates to the concrete slab using a minimum of six grade 8; size 3/8” lag bolts (bolts not provided in kit).

Connect the generator to the engine using sheaves (pulleys) and V-Belt(s):

1.

Select the correct sheaves and belts for this application.

The generator shaft is 28mm diameter x 2.38” long with a 8mm keyway. Use

Table 6 below to select the correct sheaves and belts for this application.

The shaft speed of the generator must run between 3540-3780 RPM. At no load, the correct speed is 3780 RPM.

• If the engine is a 3600-RPM engine, then a sheave diameter ratio of 1:1 should be used. This means that the diameter of the sheave on the engine

• is the same as the diameter of the sheave on the generator.

If the engine is rated at a speed less than 3600 RPM, you will need to use a larger sheave on the engine, using the following formula:

20


Acquire & install guard

Engine Speed (RPM)

=

Generator Sheave Diameter

3600 RPM Engine Sheave Diameter

If smaller than recommended sheaves are used, the life of the belt(s) will be shortened and the possibility of belt slippage increases.

Note about direct coupling:

We recommend you use belts & sheaves to transmit power from the engine to the generator. If you instead choose to direct couple, you must align the generator shaft and engine shaft exactly to within the specified tolerances of the chosen coupler. You will need to adjust the relative position of the generator and engine until both their shafts are directly aligned in all planes.

2.

Adjust belt(s) to get proper tension.

Proper belt tension is required to transmit full power from the engine to the generator at the rated speed. Belts that are too loose will slip. Belts that are too tight can bind and cause engine or generator damage.

WARNING:

Belt slippage can cause static electricity build-up, which may result in sparking. Fire ignition can result.

Step 1 . Measure L – the center-tocenter distance between the two sheaves.

Step 2.

Measure d – the deflection of the belt

Step 3.

Tighten or loosen belt until: d = 0.016 x L

If a belt tensioner is used, it should be installed on the slack run of the belt.

Install a guard over the entire power transmission assembly.

The customer is responsible for acquiring or fabricating an appropriate guard that meets all the requirements described in this section.

Note: A guard has not been supplied with the generator because the manufacturer does not know the size and dimensions of the engine to be used, nor in what configuration the customer will choose to mount the generator & engine.

21


DANGER :

All parts of the power transmission assembly must be equipped with a guard that prevents access to rotating parts. Clothing or hair can become rapidly entangled in unguarded rotating parts, resulting in serious injury or death.

Guard requirements. The guard must:

1) Prevent contact with all rotating shafts, pulleys, belts, and couplings.

2) Allow for adequate cooling ventilation and hot exhaust clearance, as described in the previous section “

4. Select a Suitable Site

”.

3) Be constructed of non-combustible, heat-resistant, durable and impactresistant material.

Expanded metal, perforated or solid sheet metal, wire mesh on a frame of angle iron, or iron pipe securely fastened to the frame can be used.

Openings in, around, and between guards can allow fingers/hands to protrude into dangerous areas where hazards exist. The allowable size of openings depends on the distance of the opening from specific hazards.

Follow the OSHA guidelines below (extracted from 20 CFR 1910.217 Table O-10) for maximum opening size:

6. Ground the generator

Always ensure the generator is properly grounded to prevent electrical shock.

You must always ground the generator by the following method when using the generator as a portable electrical source:

1) Drive a ¾” or 1” copper pipe or rod into the ground close to the generator. The pipe/rod must penetrate moist earth – the depth required will be dictated by local soil conditions.

Consult with an electrician.

2) Connect an approved ground clamp to the pipe.

3) Run a 10-gauge wire from the clamp to the generator grounding screw.

4) Do not connect the generator grounding post to a water pipe or a ground used by a radio system.

2. Preparing for Operation (Pre-start checklist)

Check that the generator and engine are mounted and connected in accordance with the instructions given earlier in this manual in the “Installation /

Initial Set-up” section, “Step 5: Mount & Connect Generator and Engine”.

WARNING:

Always ensure generator and engine are properly mounted to prevent flipping and belt slippage during use, which could cause equipment damage and injury to nearby persons, as well as development of sparks from static electricity.

Check that the generator is positioned in accordance with the instructions given earlier in this manual in the “Installation / Initial Set-up” section, “Step 4:

Select a Suitable Site”.

Operate outside only, on dry, level ground with adequate clearance and ventilation.

DANGER: Carbon monoxide poisoning hazard

The engine gives off carbon monoxide exhaust, a poisonous gas that can kill. You CANNOT smell it, see it, or taste it. ONLY run generator

OUTDOORS and away from air intakes. NEVER run generator inside any enclosed or semi-enclosed spaces, including homes, garages, basements, barns, sheds, boxes, pick-up truck beds, RVs, or boats. These spaces can trap poisonous gases, EVEN if you run a fan or open windows .

Make sure the generator is grounded in accordance with instructions given earlier in this manual in the “Installation / Initial Set-up” section, “Step 6:

Grounding the Generator”.

WARNING: Electric shock hazard

Always ensure generator is properly grounded to prevent electrical shock.

IMPORTANT: The generator must be grounded every time it is moved.

Make sure that any regular maintenance has been performed:

•

On the generator as prescribed in this manual in the “Maintenance & Repair” section;

•

On the power transmission system (belts, pulleys, couplings) as prescribed in this manual in the “Maintenance & Repair” section; and

•

On the engine as prescribed in your engine manual, including adding/changing the oil.

IMPORTANT:

Under long, continuous-run operating conditions, be prepared to check the engine oil level every time you refuel the engine. Remember to change the oil at the operating interval recommended in the engine owner’s manual.

DO NOT start the generator until any needed repairs have been completed.

26


Check/fill fuel tank

Check the engine fuel level . If needed, fill tank with fresh fuel from a portable container after first reading the following instructions and warnings:

1) Allow engine to cool for at least two minutes before removing gas cap.

Note: A running or still-hot engine is hot enough to ignite fuel.

2) When adding fuel:

- Use only a UL-approved portable fuel container to transfer fuel. Follow the safety warning and instructions below for avoiding static electric sparking.

- Do NOT overfill the fuel tank. Allow some space for fuel expansion.

- Fill fuel tank OUTDOORS – never indoors.

- Stay away from all sources of heat, sparks, and flames. Do not smoke.

3) Clean up fuel spills /splashes immediately.

• If possible, move the generator away from spilled fuel on the ground.

• Wipe up spilled fuel, and wait 5 minutes for excess fuel to evaporate before starting engine.

• Fuel soaked rags are flammable and should be disposed of properly.

• If fuel is spilled on your skin or clothes, change clothes and wash skin immediately.

4) Store extra fuel in a cool, dry place in an UL-approved, tightly sealed container.

IMPORTANT:

For continuous operation, be prepared to check and refuel the engine on a regular basis.

SPECIAL HAZARDS DURING FUELING:

WARNING : Fuel fire/explosion hazard

Gasoline is highly flammable and explosive, and standard diesel fuel is combustible. Heat, sparks, and flames can ignite fuel vapors, which can become widespread during fueling. A flash fire and/or explosion could result and cause serious injury or death. Use extreme care when handling fuel. Carefully follow all the instructions in this section to avoid the following conditions which could result in fuel vapor ignition:

•

• fuel vapor collection inside enclosures

• static electric sparks

•

• sparks from electric wiring, batteries, or running engines sources of heat (such as a hot engine or exhaust) open flames, including pilot lights

WARNING: Static electric spark hazard

A static electric spark can ignite fuel vapor, resulting in a flash fire that could cause serious injury or death.

To avoid static electric sparking while filling the fuel tank, the following steps must be followed to minimize and safely dissipate static electric charge build-up before and during the fueling process :

27

Personal

Protection


•

•

•

•

•

Always dissipate static charge from your body before beginning the fueling process by touching a grounded metal object at a safe distance from fuel sources.

Never fill the generator’s fuel tank directly from the pump – the generator’s tank is not grounded and high velocity flow from the pump can cause static electricity build-up. Use an approved portable container to transfer gas to the generator’s tank.

Never fill the portable gas container while it is sitting inside a vehicle, trailer, trunk, or pick-up truck bed. ALWAYS place container on the ground to be filled.

Keep nozzle in contact with portable container while filling.

Manually control the flow of fuel; do NOT use nozzle’s lock-open device.

A portable container made of metal or conductive plastic is preferred because it dissipates charge to ground more readily.

1.

Hearing can be damaged from prolonged, close-range exposure to the type of noise produced by this generator. The use of ear plugs or other hearing protection device is recommended for persons working within 15-20 feet of the running generator for an extended period of time.

2.

Loose or dangling apparel and long hair can become quickly entangled in moving/rotating parts. Metal jewelry can conduct electricity. Never wear jewelry or loose-fitting clothing such as neckties, scarves, or long-sleeved or untucked shirts when starting or adjusting the generator.

Tie back and secure hair close to the head.

28


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 the generator’s voltmeter to check output voltage.

3.

The voltmeter’s needle should be at or above the black line within the green area. (Note: The needle should stay in the green area during all load conditions.)

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. I f it appears that the generator itself is the problem, call NorthStar Product Support

@ 1-800-270-0810.

29


4. Connecting Loads

You will want to be careful when connecting loads so as not to overload the generator, especially if you are powering devices with motors that require a higher starting power load.

Instructions are provided below for connecting loads when you are using the generator: o As a portable power source o Connected to a building as a back-up power source

WARNING :

Do not overload generator. Make sure that combined starting and running loads do not exceed rated capacity of generator. Overloading the generator can cause damage to the generator and attached electrical devices, and may result in fire.

Using as a

Portable Power

Source

Connect electrical loads one at a time according to the following instructions:

1.

Allow engine to reach operating speed by allowing it to warm up for approximately 5 minutes before connecting electrical devices.

2.

After engine is warmed up, begin connecting the loads one at a time.

Start with those that require the highest wattage first. The recommended sequence is as follows: a.

Connect items with motors such as refrigerators, freezers, air conditioners, or small hand tools, one at a time. Let each motor stabilize before connecting the next device. b.

Connect any lights you are planning on powering. c.

Connect voltage sensitive equipment such as electronics via surge protectors. Plug devices such as TV’s, computers, and microwaves into a UL listed voltage surge protector, then plug the surge protector into the generator.

3. After connecting all loads, check the generator’s voltmeter. The needle should stay in the green area during all load conditions. If needed, adjust engine speed (if possible) until the needle is in the green area. o 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 with either the engine or the generator. o Shut off the engine and refer to the Troubleshooting guide at the end of this manual for assistance with possible problems.

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.

30


Note: Expect slight variations in voltage/speed with changing electrical

loads. All engines have a tendency to slow down when a load is applied. When electrical loads are connected to the generator, the engine is more heavily loaded and as a result the speed drops slightly.

This slight decrease in speed, together with the voltage drop within the generator itself, results in a slightly lower voltage when the generator is loaded to its full capacity than when it is running with no load. Additionally, there may be small brief surges and drops in voltage as motors connected to the generator cycle on or off.

The slight variation in voltage has no appreciable effect in the operation of motors, lights, and most appliances, as long as the voltmeter’s needle remains in the green area.

Using as a

Back-up Power

Source for a

Building

Written instructions for how to safely bring the generator online with the building’s electrical system should be provided by the electrician who installs the transfer switch, and who should also provide personal instruction to the owner/operator.

Failure to follow the proper procedure as provided by the electrician could expose persons to the hazards noted above.

Note: After you have brought the generator online with the transfer switch, you may need to adjust engine speed to maintain correct output voltage under load. (See more detail about maintaining proper voltage in the instructions given above for using the generator as a portable power source.)

5. Stopping

Stop the generator using the following steps:

1.

Disconnect all loads to generator.

(Never turn off or reduce engine speed with electrical loads connected. Damage to generator and loads will occur.)

2.

Shut OFF the engine

3.

Shut OFF fuel supply to the engine if possible.

4.

Remove spark plug to prevent accidental starting of engine.

31


6. Storage & Exercise

When you are finished using the generator, you must: o Make sure all loads to the generator are disconnected and fuel supply is shut off (if possible) o Store the generator properly o Plan on exercising the engine regularly unless the generator is prepared for long-term storage.

Detailed instructions are provided below.

Disconnect loads & shut off fuel supply

When you are finished using the generator, disconnect all loads and turn off fuel supply:

1.

Make sure all devices that were connected to the generator’s outlets have been disconnected.

2.

A hot engine can be a fire hazard.

Choose a storage location

Store the generator in a location that is: o Clean and dry o Away from sources of heat, open flames, sparks, or pilot lights, even if the generator’s fuel tank is empty. Residual fuel in the engine’s tank could ignite. o Away from extreme high or low temperatures.

Prevent accidental starting

Remove engine spark plug (s) in order to ensure the generator cannot be started accidentally in a storage location or by untrained persons.

Exercise generator every 4 weeks

The generator should be exercised regularly.

At least every four weeks, start the engine and let it run for 10 to 15 minutes with a small load plugged in, such as a lamp or fan.

Monthly exercising of the generator will: o Dry out any moisture that has accumulated in the windings. If left, this moisture can cause corrosion in the winding. o Ensure that the unit is operating properly should it be needed in an emergency.

Perform regular maintenance

Perform periodic maintenance as directed in this manual to keep the generator in safe working condition.

Prepare engine for long term storage if needed

If you will not be able to exercise the generator regularly, you must prepare the engine for long term storage to prevent gum deposits from forming and causing malfunction of the engine.

Prepare engine for long term storage by following instructions in your engine’s manual or using the following procedure:

32


o Removing all fuel from the tank and carburetor

WARNING

Carefully read and make sure you understand the following safety information before using the generator.

Improper use or maintenance of the generator can result in serious injury or death from

carbon monoxide poisoning, electric shock, entanglement, fire, or burns. In addition, the generator can lift or flip and cause severe injury if improperly secured.

General

•

Read manual.

Read this Owner’s Manual and the engine Owner’s Manual completely before attempting to set-up and use the generator . Serious injury or death can result if safety instructions are not followed.

•

Instruct operators . The generator owner must instruct all operators in safe generator set-up and operation. Do not allow anyone to operate the generator who has not read the Owner’s Manual and been instructed on its safe use.

•

Adults only.

Only trained adults should set up and operate the generator. Do not let children operate.

•

Under the influence . Never operate, or let anyone else operate, the generator while under the influence of alcohol, drugs, or medication.

•

Intended use . Carefully read about and understand the intended use of this generator. Do not use for other purposes, as unforeseen hazards or equipment damage may result.

Prohibition Against Modifications

•

Modifications prohibited.

Never modify or alter the generator in any way. Modifications can create serious safety hazards and will also void the warranty.

•

Fuel/exhaust system . Never modify the engine’s exhaust system, fuel tank, or fuel lines. Carbon monoxide poisoning, fire, or explosion could result.

•

Guards . Do not operate generator unless all guards and cover shields, which prevent access to moving parts and pinch points, are in place. Failure to guard the power transmission mechanisms may result in serious injury or death.

Safety – Installation & Set-up

•

Mount generator and engine.

Failure to properly mount the generator may cause the unit to lift or flip during use, which could result in severe injury to the operator or bystanders, or cause damage to surrounding objects.

•

The generator and engine must be securely mounted to a common base such as a heavy-duty metal plate.

•

The mounting base must be of adequate size and strength to withstand operating torque and vibration without either flipping or experiencing stress failure.

• See the “Installation / Initial Set-Up” section of this Owner’s Manual for mounting requirements and instructions.

•

Power transmission guarding.

The power transmission assembly must be equipped with a guard that prevents contact with all rotating shafts, pulleys, belts, and couplings. Clothing or hair can become rapidly entangled in unguarded rotating parts, resulting in serious injury or death. This guard is not supplied with the unit because the generator manufacturer does not know the size and dimensions of the engine to be used. The customer is responsible for installing an appropriate guard.

•

Dry, level surface . Situate generator on a dry, firm, level surface. Ensure generator sits level and will not slide or shift during operation.

•

DANGEROUS carbon monoxide exhaust - Operate OUTSIDE only ! The engine gives off carbon monoxide exhaust, a poisonous gas that can kill. You CANNOT smell it, see it, or taste it. ONLY run generator OUTDOORS and away from building air intakes. NEVER run generator inside homes, garages,

37

Summary of Important Safety Information (cont’d)

barns, sheds, or other semi-enclosed spaces. These spaces can trap poisonous gases, EVEN if you run a fan or open windows.

•

Cooling ventilation . The generator needs adequate, unobstructed flow of air to allow for proper cooling of engine and generator head so it does not overheat and possibly cause fire. Situate so there is adequate clearance around generator to allow for cooling airflow. Do not allow debris to accumulate and block airflow.

Keep all objects at least 7 feet away from vent slots.

•

Grounding . Always ensure generator is properly grounded to prevent electrical shock. This generator is equipped with a grounding screw. Always complete the grounding path from the generator to a copper pipe/rod driven into moist earth to a sufficient depth. Check with an electrician for local grounding requirements. If a licensed electrician installs the generator with a connection to your building’s electrical circuit for use as a standby power system, grounding will be complete through the building’s grounding system.

• Isolate connection to building’s electrical circuit . Never plug the generator directly into a wall outlet. ANY connection to a building’s electrical system MUST ISOLATE THE GENERATOR FROM UTILITY POWER via an UL-approved transfer switch installed by a licensed electrician in compliance with all applicable local building and electrical codes. If the generator is not isolated from the utility power system by such means, generator output will back feed into the utility power grid. This may result in injury or death to utility power workers or others who contact the lines during a power outage. It may also cause the generator to explode or cause fire when utility power is restored.

•

Wet conditions . Water conducts electricity. Do not operate generator where it is wet. Operate on a dry surface under an open, canopy-like structure.

•

Hot engine exhaust . Engine exhaust can be extremely hot and cause fire. Refer to your engine manual to determine safe clearance distance required between hot exhaust and nearby combustible objects.

•

Belt tension.

Belt slippage can cause static electricity build-up, which may result in sparking. Fire ignition can result. Follow instructions in this manual for adjusting belt tension.

•

CO alarms . Ensure that working, battery-operated or battery back-up carbon monoxide alarms are used in any dwelling/structure that is in close proximity to the running generator.

•

Fire extinguisher . Keep a fire extinguisher rated “ABC” by the National Fire Protection Association nearby.

Keep it properly charged and be familiar with its use.
