2.3 HOW TO USE THE GENERATOR

If you have any problems operating your generator, please call the generator helpline at 1-800-333-1322.

2.3.1 GROUNDING THE GENERATOR

The National Electrical Code requires that the frame

and external electrically conductive parts of this

generator be properly connected to an approved earth

ground. Local electrical codes may also require proper

grounding of the unit. For that purpose, generally, connecting a No. 10 AWG (American Wire Gauge) stranded copper wire to the grounding wing nut and to an earth-driven copper or brass grounding rod (electrode) provides adequate protection against electrical shock. However, local codes may vary widely. Consult

with a local electrician for grounding requirements in

your area.

Figure 13 - Grounding the Generator

Proper grounding of the generator will help prevent

electrical shock in the event of a ground fault condition in the

generator or in connected electrical devices. Proper grounding also helps dissipate static electricity, which often builds up in ungrounded devices.

2.3.2 CONNECTING ELECTRICAL LOADS

DO NOT connect 240 Volt loads to 120 Volt receptacles. DO NOT connect 3-phase loads to the generator. DO NOT connect

50 Hz loads to the generator.

• Let engine stabilize and warm up for a few minutes after

starting.

• Plug in and turn on the desired 120 or 240 Volt AC, single

phase, 60 Hz electrical loads.

• Add up the rated watts (or amps) of all loads to be connected

at one time. This total should not be greater than (a) the rated wattage/amperage capacity of the generator or (b) circuit breaker rating of the receptacle supplying the power. See "Don't Overload the Generator" below.

2.4 DON’T OVERLOAD THE

GENERATOR

Overloading a generator in excess of its rated wattage capacity can result in damage to the generator and to connected electrical devices. Observe the following to prevent overloading the unit:

• Add up the total wattage of all electrical devices to be

connected at one time. This total should NOT be greater than the generator's wattage capacity.

• The rated wattage of lights can be taken from light bulbs. The

rated wattage of tools, appliances and motors can usually be found on a data plate or decal affixed to the device.

• If the appliance, tool or motor does not give wattage, multiply

volts times ampere rating to determine watts (volts x amps = watts).

• Some electric motors, such as induction types, require about

three times more watts of power for starting than for running. This surge of power lasts only a few seconds when starting such motors. Make sure you allow for this high starting wattage when selecting electrical devices to connect to your generator:

1. Figure the watts needed to start the largest motor.

2. Add to that figure the running watts of all other connected

loads.

The Wattage Reference Guide on page 10 is provided to assist you in determining how many items your generator can operate at one time. (Note: All figures are approximate. See data plate on appliance for wattage requirements.)

Section 2 – Operation

Commercial-Industrial-Residential Portable Generator System

2.6 BEFORE STARTING THE

GENERATOR

Prior to operating the generator, engine oil and gasoline will need to be added, as follows:

2.6.1 ADDING ENGINE OIL

NOTE: When adding oil to the engine crankcase in

the future, use only high quality detergent oil rated

with API service classification SF or SG SAE 30

weight. Use no special additives.

Select the oil’s viscosity grade according to the expected operating temperature. Do not use SAE 10W-40.

• Above 40°F, use SAE 10W-30 or SAE 30.

• Below 40°F, use synthetic 5W-20 or 5W-30.

Although multi-viscosity oils (5W-30, 10W-30, etc.) improve starting in cold weather, these multi-viscosity oils will result in increased oil consumption when used above 32°F. Check your engine oil level more frequently to avoid possible damage from running low on oil.

• Place generator on a level surface.

• Clean area around oil fill and remove oil fill cap and dipstick.

• Wipe dipstick clean.

• Slowly fill engine with oil through the oil fill opening until it

reaches the full mark on the dipstick. Stop filling occasionally to check oil level. DO NOT OVERFILL.

• Install dipstick. Install oil fill cap and finger tighten securely.

• Check engine oil level before starting each time thereafter.

Page 13

2.6.2 ADDING GASOLINE

 WARNING: Never fill fuel tank indoors. Never fill

fuel tank when engine is running or hot. DO NOT

light a cigarette or smoke when filling the fuel

tank.

 Caution:

Do not overfill the fuel tank. Always

leave room for fuel expansion.

• Use regular UNLEADED gasoline with the generator engine. Do not use premium gasoline. Do not mix oil with gasoline.

• Clean area around fuel fill cap, remove cap.

• Slowly add unleaded regular gasoline to fuel tank. Be careful not to overfill. Allow about 1/2" of tank space for fuel expansion, as shown here.

• Install fuel cap and wipe up any spilled gasoline.

Figure 14 - Fuel Tank

IMPORTANT: It is important to prevent gum deposits from forming in fuel system parts such as the carburetor, fuel hose or tank during storage. Alcohol-blended fuels (called gasohol, ethanol or methanol) can attract moisture, which leads to separation and formation of acids during storage. Acidic gas can damage the fuel system of an engine while in storage. To avoid engine problems, the fuel system should be emptied before storage of 30 days or longer. See "Storage" on page 18. Never use engine or carburetor cleaner products in the fuel tank as permanent damage may occur.

2.7 TO START THE ENGINE



WARNING! Never start or stop engine with electrical

devices plugged into the receptacles AND devices turned on.

• Unplug all electrical loads from the unit's receptacles before starting the engine.

• Make sure the unit is in a level position.

• Open the fuel shut-off valve.

Figure 15 - Fuel Shut-off Valve

• Locate the Idle Control ON/OFF switch on the control panel and set it to the “OFF” position.

Figure 16 - Idle Control Switch

Section 2 — Operation

Commercial-Industrial-Residential Portable Generator System

-------------

 WARNING 

-------------

Page 14

• Move engine CHOKE knob to “Full Choke” position.

Figure 17 - Full Choke Position

• To start engine, press and hold the Start/Run/Stop switch in the “Start” position. The engine will crank and attempt to start. When the engine starts, release the switch to the run position.

• When the engine starts, move choke knob to “1/2 Choke” position until the engine runs smoothly and then to “Run” position. If engine falters, move choke knob to “1/2 Choke” position until the engine runs smoothly and then to “Run” position.

Note: If engine fires, but does not continue to run,

move choke lever to “Full Choke” and repeat starting

instructions.

2.8 STOPPING THE ENGINE

• Shut off all loads, then unplug the electrical loads from generator panel receptacles. Never start or stop the engine with electrical devices plugged in and turned on.

• Turn “Off” the Idle Control switch (if on).

• Let engine run at no-load for several minutes to stabilize the internal temperatures of engine and generator.

• Move Start/Run/Stop switch to “Off” position.

• Close fuel valve.

IMPORTANT: Do not overload the generator. Also, do not overload individual panel receptacles. These outlets are protected against overload with push-to-reset-type circuit breakers. If amperage rating of any circuit breaker is exceeded, that breaker opens and electrical output to that receptacle is lost. Read “Don’t Overload the Generator” on page 9 carefully.

2.9 AUTOMATIC IDLE CONTROL

This feature is designed to greatly improve fuel economy. When this switch is turned “On,” the engine will only run at its normal fast governed engine speed when electrical load is connected. When the load is removed, the engine will run at a reduced speed of 2100 RPM. With the switch “Off,” the engine runs at the normal fast engine speed all the time. Always have the

switch OFF when starting and stopping the engine.

2.10 COLD WEATHER OPERATION/

DE-ICER

Under certain weather conditions (temperatures below 40° F (4° C) and a high dew point), the engine may experience icing of the carburetor and/or the crankcase breather system. To eliminate this problem, this generator engine is fitted with a winter/summer valve. this directs hot air into the carburetor during cold weather operation. Always make sure the winter/summer valve is in the correct location relative to the weather conditions.

2.11 LOW OIL PRESSURE SHUTDOWN

SYSTEM

The engine is equipped with a low oil pressure sensor that shuts down the engine automatically when the oil pressure drops below 10 psi. If the engine shuts down by itself and the fuel tank has enough gasoline, check engine oil level.

2.11.1 INITIAL START-UP

A delay built into the low oil shutdown system allows oil pressure to build during starting. The delay allows the engine to run for about 10 seconds before sensing oil pressure.

2.11.2 SENSING LOW OIL PRESSURE

If the system senses low oil pressure during operation, the engine shuts down.

2.11.3 RESTARTING

If you try to restart the engine within 10 seconds after it shuts down, the engine may NOT start. The system needs 5 to 10 seconds to reset.

If you do restart the engine after such a shutdown and have not corrected the low oil pressure, the engine runs for about 10 seconds as described above and then stops.

2.12 CHARGING A BATTERY



DANGER! Storage batteries give off explosive hydrogen

gas while recharging. An explosive mixture will remain around the battery for a long time after it has been charged. The slightest spark can ignite the hydrogen and cause an explosion. Such an explosion can shatter the battery and cause blindness or other serious injury.

 DANGER! Do not permit smoking, open flame, sparks

or any other source of heat around a battery. Wear protective goggles, rubber apron and rubber gloves when working around a battery. Battery electrolyte fluid is an extremely caustic sulfuric acid solution that can cause severe burns. If spill occurs flush area with clear water immediately.

Your generator has the capability of recharging a discharged 12 Volt automotive or utility style storage battery. Do not use the

unit to charge any 6 Volt batteries. Do not use the unit

to crank an engine having a discharged battery.

To recharge 12 Volt batteries, proceed as follows:

• Check fluid level in all battery cells. If necessary, add ONLY distilled water to cover separators in battery cells. Do not

use tap water.

• If the battery is equipped with vent caps, make sure they are installed and are tight.

• If necessary, clean battery terminals.

• Connect battery charge cable connector plug to panel receptacle identified by the words "12-VOLT D.C."

• Connect battery charge cable clamp with red handle to the positive (+) battery terminal.

• Connect battery charge cable clamp with black handle to the negative (-) battery terminal.

• Start engine. Let the engine run while battery recharges. Engine idle control switch must

be in off position for battery

charging.

• When battery has charged, shut down engine.

Note: Use an automotive hydrometer to test battery

state of charge and condition. Follow the hydrometer

manufacturer's instructions carefully. Generally, a

battery is considered to be at 100% state of charge

when specific gravity of its fluid (as measured by

hydrometer) is 1.260 or higher.

Follow the calendar intervals. More frequent service is required when operating in adverse conditions noted below.

Operation Maintenance Daily Every Season Every Season Every Season

PRODUCT SPECIFICATIONS

Page 17

3.3 GENERAL RECOMMENDATIONS

The warranty of the generator does not cover items that have been subjected to operator abuse or negligence. To receive full value from the warranty, the operator must maintain the generator as instructed in this manual.

Some adjustments will need to be made periodically to properly maintain the generator.

All adjustments in the Maintenance section (3) of this manual should be made at least once each season. Follow the requirements in the "Maintenance Schedule" chart on page 14.

NOTE: Once a year you should replace the spark plug

and replace the air filter. A new spark plug and clean

air filter assure proper fuel-air mixture and help your

engine run better and last longer.

3.3.1 GENERATOR MAINTENANCE

Generator maintenance consists of keeping the unit clean and dry. Operate and store the unit in a clean dry environment where it will not be exposed to excessive dust, dirt, moisture or any corrosive vapors. Cooling air slots in the generator must not become clogged with snow, leaves, or any other foreign material.

Check the cleanliness of the generator frequently and clean when dust, dirt, oil, moisture or other foreign substances are visible on its exterior surface.

CAUTION! Never insert any object or tool through the air

cooling slots, even if the engine is not running.

Note: DO NOT use a garden hose to clean generator.

Water can enter the engine fuel system and cause

problems. In addition, if water enters the generator

through cooling air slots, some water will be retained

in voids and crevices of the rotor and stator winding

insulation. Water and dirt buildup on the generator

internal windings will eventually decrease the

insulation resistance of these windings.

3.3.2 TO CLEAN THE GENERATOR

• Use a damp cloth to wipe exterior surfaces clean.

• A soft, bristle brush may be used to loosen caked on dirt, oil, etc.

• A vacuum cleaner may be used to pick up loose dirt and debris.

• Low pressure air (not to exceed 25 psi) may be used to blow away dirt. Inspect cooling air slots and openings on the generator. These openings must be kept clean and unobstructed.

3.3.3 ENGINE MAINTENANCE

DANGER! When working on the generator, always disconnect negative cable from battery. Also disconnect spark plug wires from spark plug and keep wire away from spark plug.

3.3.4 CHECKING OIL LEVEL

See the “BEFORE STARTING THE GENERATOR” section on page 10 for information on checking the oil level. The oil level should be checked before each use, or at least every eight hours of operation. Keep the oil level maintained.

3.3.5 CHANGING THE OIL AND OIL FILTER

Change the oil and filter after the first eight hours of operation. Change the oil every 100 hours thereafter. If you are running this unit under dirty or dusty conditions, or in extremely hot weather, change the oil more often.

Use the following instructions to change the oil while

the engine is still warm:

• Clean area around oil drain hose and plug.

• Remove oil drain plug from end of hose and oil fill plug to drain oil completely into a suitable container.

• When oil has completely drained, install oil drain plug and tighten securely.

• Place a suitable container beneath the oil filter and turn filter counterclockwise to remove. Discard according to local regulations.

• Coat gasket of new filter with clean engine oil. Turn filter clockwise until gasket contacts lightly with filter adapter. Then tighten an additional 3/4 turn.

• Fill oil sump with recommended oil. (See “Before Starting the Generator” on page 10 for oil recommendations).

• Wipe up any spilled oil.

3.4 SERVICE AIR CLEANER

Your engine will not run properly and may be damaged if you run it using a dirty air cleaner. Clean or replace the air cleaner paper filter once a year. Clean or replace more often if operating under dusty conditions. Clean foam pre-cleaner every month or more often under dusty conditions.

Figure 20 - Air Cleaner

To clean or replace foam pre-cleaner:

• Remove air cleaner cover, then foam pre-filter.

• Wash pre-cleaner in soapy water. Squeeze pre-filter dry in clean cloth (DO NOT TWIST).

• Clean air cleaner cover before re-installing it.

To clean or replace paper air filter:

• Remove air cleaner cover; then remove foam pre-filter (service

if necessary) and remove paper filter.

• Clean paper filter by tapping it gently on a solid surface. If the

filter is too dirty, replace it with a new one. Dispose of the old filter properly.

• Clean air cleaner cover then slip pre-cleaner over filter. Next

insert new paper filter into the base of the air cleaner. Reinstall air cleaner cover.

Note: To order a new air filter, please contact the

nearest authorized service center at 1-800-333-1322.

3.5 CLEAN SPARK ARRESTOR

SCREEN

The engine exhaust muffler has a spark arrestor screen. Inspect and clean the screen at least once each year. If unit is used regularly, inspect and clean more often.

NOTE: If you use your generator on any forest-

covered, brush-covered or grass-covered unimproved

land, it must equipped with a spark arrestor. The spark

arrestor must be maintained in good condition by the

owner/operator.

Clean and inspect the spark arrestor as follows:

• Remove the screen retaining bracket by removing the screw.

• Slide the spark arrestor screen out from the tail pipe.

• Inspect screen and replace if torn, perforated or otherwise

damaged. DO NOT USE a defective screen. If screen is not damaged, clean it with commercial solvent.

3.6 ADJUSTING VALVE CLEARANCE

After the first 50 hours of operation, you should adjust

the valve clearance in the engine.

Important: If you feel uncomfortable about doing this procedure

or you don't have the proper tools, please take your generator in to the nearest service center to have the valve clearance adjusted. This is a very important step to insure longest life for your engine.

To adjust valve clearance:

• Make sure the engine is at room temperature.

• Make sure that the spark plug wire is removed from the spark plug and out of the way.

• Remove the four screws attaching the valve cover with a #2 or #3 phillips screwdriver.

• Make sure the piston is at Top Dead Center (TDC) of its compression stroke (both valves closed). To get the piston at TDC, remove the intake screen at the front of the engine to gain access to the flywheel nut. Use a large socket and socket wrench to rotate the nut and hence the engine. While watching the piston through the spark plug hole. The piston should move up and down. The piston is at TDC when it is up as high as it can go.

• Loosen the rocker jam nut. Use an 10mm allen wrench to turn the pivot ball stud while checking clearance between the rocker arm and the valve stem with a feeler gauge. Correct clearance is 0.002-0.004 inch (0.05-0.1 mm).

NOTE: You must hold the rocker arm jam nut in place

as you turn the pivot ball stud.

When valve clearance is correct, hold the pivot ball stud in place with the allen wrench and tighten the rocker arm jam nut. Tighten the jam nut to 174 in/lbs. torque. After tightening the jam nut, recheck valve clearance to make sure it did not change.

Figure 22 - Valve Clearance Adjustment

• Install new valve cover gasket.

• Re-attach the valve cover.

NOTE: Start all four screws before tightening or you

will not be able to get all the screws in place. Make

sure the valve cover gasket is in place.

• Re-attach the spark plug wire to the spark plug.

• Repeat the process for the other cylinder.

3.7 GENERAL

The generator should be started at least once every seven days and be allowed to run at least 30 minutes. If this cannot be done and you must store the unit for more than 30 days, use the following information as a guide to prepare it for storage.

 DANGER! NEVER store engine with fuel in

tank indoors or in enclosed, poorly ventilated

areas where fumes may reach an open flame,

spark or pilot light as on a furnace, water heater,

clothes dryer or other gas appliance.

3.8 LONG TERM STORAGE

It is important to prevent gum deposits from forming in essential fuel system parts such as the carburetor, fuel hose or tank during storage. Also, experience indicates that alcohol-blended fuels (called gasohol, ethanol or methanol) can attract moisture, which leads to separation and formation of acids during storage. Acidic gas can damage the fuel system of an engine while in storage.

To avoid engine problems, the fuel system should be emptied before storage of 30 days or longer, as follows:

• Remove all gasoline from the fuel tank.

DANGER! Drain fuel into approved container

outdoors, away from open flame. Be sure engine

is cool. Do not smoke.

• Start and run engine until engine stops from lack of fuel.

• While engine is still warm, drain oil from crankcase. Refill with recommended grade.

• Remove spark plugs and pour about 1/2 ounce (15 ml) of engine oil into the cylinders. Cover spark plug hole with rag. Press the “Start” button and allow engine to crank for 2 seconds. Then press the “Stop” button.

CAUTION! Avoid spray from spark plug holes

when cranking engine.

• Install and tighten spark plugs. Do not connect spark plug wires.

• Clean the generator outer surfaces. Check that cooling air slots and openings on generator are open and unobstructed.

• Store the unit in a clean, dry place.

3.9 OTHER STORAGE TIPS:

• Do not store gasoline from one season to another.

• Replace your gasoline can if your can starts to rust. Rust and/or dirt in your gasoline will cause problems with the carburetor and fuel system.

• If possible, store your unit indoors and cover it to give protection from dust and dirt. BE SURE TO EMPTY THE

FUEL TANK.

• If it is not practical to empty the fuel tank and the unit is to be stored for some time, use a commercially available fuel stabilizer added to the gasoline to increase the life of the gasoline.

• Cover your unit with a suitable protective cover that does not retain moisture.

 DANGER! NEVER cover your generator while

engine and exhaust area are warm.

(a) Applicability: This warranty shall apply to 1995 and later model year engines. The ECS Warranty period shall begin on the date the new engine or

equipment is purchased by/delivered to its original, end-use purchaser/owner and shall continue for 24 consecutive months thereafter.

(b) General Emissions Warranty Coverage: Generac warrants to the original, end-use purchaser/owner of the new engine or equipment and to each

subsequent purchaser/owner that each of its engines is...

(1) Designed, built and equipped so as to conform with all applicable regulations adopted by the CARB pursuant to its authority, and

(2) Free from defects in materials and workmanship which, at any time during the ECS Warranty Period, may cause a warranted emissions-related part

to fail to be identical in all material respects to the part as described in the engine manufacturer's application for certification.

The ECS Warranty pertains only to emissions-related parts on your engine, as follows:

(1) Any warranted, emissions-related parts that are not scheduled for replacement as required maintenance in the Owner's Manual shall be warranted

for the ECS Warranty Period. If any such part fails during the ECS Warranty Period, it shall be repaired or replaced by Generac according to Subsection (4) below. Any such part repaired or replaced under the ECS Warranty shall be warranted for the remainder of the ECS Warranty Period.

(2) Any warranted, emissions-related part that is scheduled only for regular inspection as specified in the Owner's Manual shall be warranted for the ECS

Warranty Period. A statement in such written instructions to the effect of "repair or replace as necessary" shall not reduce the ECS Warranty Period. Any such part repaired or replaced under the ECS Warranty shall be warranted for the remainder of the ECS Warranty Period.

(3) Any warranted, emissions-related part that is scheduled for replacement as required maintenance in the Owner's Manual shall be warranted for the

period of time prior to first scheduled replacement point for that part. If the part fails prior to the first scheduled replacement, the part shall be repaired or replaced by Generac according to Subsection (4) below.
