BEFORE STARTING ENGINE

Add Oil

NOTE: When adding oil to the engine crankcase in the future, use only high-quality detergent oil rated with API service classification SG, SF/CC, and CD. Select the oil’s viscosity grade according to your expected operating temperature:
SAE 10W-30 is recommended for general all temperatures use. Multi-viscosity oils (10W30, etc.) improve starting in cold weather, but these oils will result in increased oil consumption. Check your engine oil level more frequently to avoid possible damage from running low on oil.

To Add Engine Oil:

Place the generator on a level surface.
Remove the oil fill cover.
Remove oil filler cap and wipe dipstick clean (Figure 2).

Add Gasoline

Use clean fresh UNLEADED gasoline with a pump rating of 86 or higher. Do not use premium or leaded gasoline. Do Not mix oil with gasoline.
Clean area around fuel fill cap, remove cap.
Check the fuel level.
If fuel level is low, slowly add recommended gasoline to the fuel tank, up to the shoulder of the fuel strainer (Figure 3). Be careful not to overfill (there should be no fuel in the filler neck).
Install fuel cap and wipe up any spilled gasoline. Occasionally you may hear a light “spark knock” or “pinging” (metallic rapping noise) while operating under
heavy loads. This is no cause for concern. If spark knock or pinging occurs at a steady engine speed under normal load, change brands of gasoline or obtain a higher octane rated fuel. If pinging or spark knock persists, see your local Generac repair center

OPERATING THE GENERATOR

Starting the Engine

Disconnect all electrical loads from the generator. Use the following start instructions:

Be sure the spark plug wire is attached to the spark plug.
Turn the fuel valve to the “Open” position (fully clockwise) (Figure 4).
Slide the choke lever to the “Choke” position (all the way to the right) (Figure 5).

Connecting Electrical Loads

Let the engine stabilize and warm up for a few minutes after starting.
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.
Plug in and turn on the desired 120 Volt AC, single phase, 60 Hertz electrical loads.
DO NOT OVERLOAD THE GENERATOR. Add up the rated watts (or amps) of all loads to be connected at one time. This total should not be greater than the rated wattage/amperage capacity of the generator. See “Don’t Overload the Generator” on page 9.

Charging a Battery

WARNING! Do not permit smoking, open flame, sparks or any other source of heat around a battery. Do not use a lighter or other flame for checking battery fluid levels. 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. Do not permit fluid contact with eyes, skin, clothing, etc. 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:

If necessary, clean battery posts or terminals.
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.
Connect battery charge cable connector plug to the 12 Volt DC panel receptacle.
Connect battery charge cable clamp with red handle to battery post or terminal indicated by Positive, POS or (+) (Figure 7).
Connect battery charge cable clamp with black handle to battery post or terminal indicated by Negative, NEG, or (–) (Figure 7).
Start generator. Let the engine run while the battery recharges.
When battery has charged, shut down engine (see “Stopping The Engine”)

CONNECTOR PLUGS

12 Volt DC Accessory Jack

This receptacle allows you to recharge a 12 Volt automotive or utility style storage battery with the battery charge cable provided. Camping-style air pumps, lanterns, fans, or other 12 Volt devices having a cigarette lighter-type plug may also be powered by this outlet (Figure 9).

DON’T OVERLOAD THE GENERATOR

Overloading a generator in excess of its rated wattage capacity can result in damage to the generator and/or 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 120 Volts times the ampere rating to determine watts (volts x amps = watts).

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.
1. Clean more often under dirty or dusty conditions. Replace cleaner parts if very dirty.
2. Check every 10 hours or 3 months.
3. These items should be serviced by an authorized dealer, unless the owner has the proper tools and is mechanically proficient.
Check the cleanliness of the generator frequently and clean when dust, dirt, oil, moisture or other foreign substances are visible on its exterior surface.
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 the cooling air slots, some of the water will be retained in voids and cracks 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.

To Clean the Generator

Use a damp cloth to wipe exterior surfaces clean.
Soft, bristle brush may be used to loosen caked-on dirt or oil
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 opening on the generator. These openings must be kept clean and unobstructed.

ENGINE MAINTENANCE

Changing Engine Oil

Change the oil after the first month of operation, then every 25 hours. If you are using your generator under extremely dirty or dusty conditions, or in extremely hot weather, change the oil more often. Change the oil while the engine is still warm from running, as follows:

Clean/Replace Spark Plug

Check and clean the spark plug every 50 hours of operation or every three months, whichever comes first. This will help your engine to start easier and run better.

Remove spark plug access cover. Remove spark plug cap.
Clean the area around the spark plug.
Remove and inspect the spark plug.
Replace the spark plug if electrodes are pitted or burned or the porcelain is cracked. Use recommended plug for replacement.
Check electrode gap with wire feeler gauge and set spark plug gap between 0.028 a

Service Air Cleaner

To clean or replace air filter element:

Loosen the air cleaner cover screws, remove the air cleaner cover, and remove the element (see item number 4, exploded view on page 20.
Wipe clean the inside of the filter housing and cover thoroughly.
Wash the element in a solution of household detergent and warm water, then rinse thoroughly. Or wash in a nonflammable or high flash point solvent. Allow the element to dry thoroughly.
Soak the element in clean engine oil and squeeze out the excess oil. Do Not twist. The engine will smoke during initial start-up if too much oil is left in the element.
Use a brass or stiff-bristle brush to remove carbon deposits from the spark arrester surface.
Inspect the spark arrester for breaks or tears and replace it if necessary.

Long Term Storage Instructions

More than One Year

It is important to prevent gum deposits from forming in essential fuel system parts such as the carburetor, fuel filter, 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. Follow these instructions:

Protect Fuel System

Drain carburetor float bowl and fuel tank into a suitable container by loosening the drain screw (Figure 14).
