Fuel Safety

DANGER

PETROL, PETROL VAPOURS AND LIQUID PETROLEUM GAS (LPG) ARE HIGHLY FLAMMABLE AND EXPLOSIVE. Fire or explosion can cause severe burns or death. Unintentional startup can result in entanglement, traumatic amputation or laceration.

Petrol and Petrol Vapours:

• PETROL IS HIGHLY FLAMMABLE AND EXPLOSIVE.
• Petrol can cause a fi re or explosion if ignited.
• Petrol is a liquid fuel but it’s vapours can ignite.
• Petrol is a skin irritant and needs to be cleaned up immediately if spilled on skin or clothes.
• Petrol has a distinctive odour, this will help detect potential leaks quickly.
• n any petrol fi re, fl ames should not be extinguished unless by doing so the fuel supply valve can be turned OFF. This is because if a fi re is extinguished and a supply of fuel is not turned OFF, then an explosion hazard could be created.
• Petrol expands or contracts with ambient temperatures. Never fi ll the petrol tank to full capacity, as petrol needs room to expand if temperatures rise.

Liquefi ed Petroleum Gas (LPG):

• LPG IS HIGHLY FLAMMABLE AND EXPLOSIVE.
• Flammable gas under pressure can cause a fi re or explosion if ignited.
• LPG is heavier than air and can settle in low places while dissipating.
• LPG has a distinctive odour added to help detect potential leaks quickly.
• In any petroleum gas fi re, fl ames should not be extinguished unless by doing so the fuel supply valve can be turned OFF. This is because if a fi re is extinguished and a supply of fuel is not turned OFF, then an explosion hazard could be created.
• When exchanging LPG cylinders, be sure the cylinder valve is of the same type.
• Always keep the LPG cylinder in an upright position.
• LPG will burn skin if it comes in contact with it. Keep any and all LPG away from skin at all times.

When adding or removing Petrol:
Turn the generator off and let it cool for at least two minutes before removing the fuel cap. Loosen the cap slowly to relieve pressure in the tank. Only fi ll or drain fuel outdoors in a well-ventilated area. DO NOT pump petrol directly into the generator at the petrol station. Use an approved container to transfer the fuel to the generator. DO NOT overfi ll the fuel tank. Always keep fuel away from sparks, open fl ames, pilot lights, heat and other sources of ignition. DO NOT light or smoke cigarettes.

When starting the generator:
DO NOT attempt to start a damaged generator. Make certain that the petrol cap, air fi lter, spark plug, fuel lines and exhaust system are properly in place. Allow spilled fuel to evaporate fully before attempting to start the engine. Make certain that the generator is resting fi rmly on level ground.

When operating the generator:
DO NOT move or tip the generator during operation. DO NOT tip the generator or allow fuel or oil to spill.

When transporting or servicing the generator:
Make certain that the fuel shutoff valve is in the off position and the fuel tank is empty. Make certain that a LPG cylinder is not attached to generator and is securely stowed away. Disconnect the spark plug wire.

When storing the generator:
Store away from sparks, open fl ames, pilot lights, heat and other sources of ignition. Do not store generator, petrol or LPG cylinder near furnaces, water heaters, or any other appliances that produce heat or have automatic ignitions.

WARNING
Never use a petrol container, LPG connector hose, petrol tank, LPG cylinder or any other fuel item that is damaged or appears damaged.

Add Engine Oil

CAUTION

DO NOT attempt to crank or start the engine before it has been properly fi lled with the recommended type and amount of oil. Damage to the generator as a result of failure to follow these instructions will void your warranty.

NOTE

The generator rotor has a sealed, pre-lubricated ball bearing that requires no additional lubrication for the life of the bearing.

NOTE

The recommended oil type is 10W-30 automotive oil.

1. Place the generator on a fl at, level surface.
2. Remove oil fi ll cap/dipstick to add oil.
3. Add oil and replace oil fi ll cap/dipstick. DO NOT OVERFILL.
4. Check engine oil level daily and add as needed.

NOTE
Once oil has been added, a visual check should show oil about 1-2 threads from running out of the fi ll hole. If using the dipstick to check oil level, DO NOT screw in the dipstick while checking.

Add Engine Oil Cont’d.

NOTE

Check oil often during the break-in period. Refer to the Maintenance section for recommended service intervals.

CAUTION
The engine is equipped with a low oil shut-off and will stop when the oil level in the crankcase falls below the threshold level.

NOTE
We consider the fi rst 5 hours of run time to be the break-in period for the unit. During the break in period stay at or below 50% of the running watt rating and vary the load occasionally to allow stator windings to heat and cool. Adjusting the load will also cause engine speed to vary and help seat piston rings. After the 5 hour break-in period, change the oil.

NOTE
Weather will affect engine oil and engine performance. Change the type of engine oil used based on weather conditions to suit the engine needs.

NOTE
Synthetic oil may be used after the 5 hour initial break-in period. Using synthetic oil does not increase the recommended oil change interval. Full synthetic 5W-30 oil will aid in starting in cold ambient <5°C (41ºF)

Add Fuel (Petrol)

1. Use clean, fresh, regular unleaded fuel with a minimum octane rating of 85 and an ethanol content of less than 10% by volume.
2. DO NOT mix oil with fuel.
3. Clean the area around the fuel cap.
4. Remove the fuel cap.
5. Slowly add fuel to the tank. DO NOT OVERFILL. Fuel can expand after fi lling. A minimum of 6.4 mm (¼ in.) of space left in the tank is required for fuel expansion, more than 6.4 mm (¼ in.) is recommended. Fuel can be forced out of the tank as a result of expansion if it is overfi lled, and can affect the stable running condition of the product. When fi lling the tank, it is recommended to leave enough space for the fuel to expand.
6. Screw on the fuel cap and wipe away any spilled fuel.

CAUTION
Use regular unleaded petrol with a minimum octane rating of 85.

• Do not mix oil and petrol.
• Fill tank to approximately 6.4 mm (¼ in.) below the top of the tank to allow for fuel expansion.
• DO NOT pump petrol directly into the generator at the petrol station. Use an approved container to transfer the fuel to the generator.
• DO NOT fi ll fuel tank indoors.
• DO NOT fi ll fuel tank when the engine is running or hot. DO NOT overfi ll the fuel tank.
• DO NOT light cigarettes or smoke when fi lling the fuel tank.

Add Fuel (Petrol) Cont’d.

WARNING
Pouring fuel too fast through the fuel screen may result in blow back of fuel at the operator while fi lling.

NOTE
Our engines work well with 10% or less ethanol blend fuels. When using blended fuels there are some issues worth noting:

• Ethanol-petrol blends can absorb more water than petrol alone.
• These blends can eventually separate, leaving water or a watery goo in the tank, fuel valve and carburetor.
• With gravity-fed fuel supplies, this compromised fuel can be drawn into the carburetor and cause damage to the engine and/or potential hazards.
• There are only a few suppliers of fuel stabilizer that are formulated to work with ethanol blend fuels.
• Any damages or hazards caused by using improper fuel, improperly stored fuel, and/ or improperly formulated stabilizers, are not covered by manufacture’s warranty.

It is advisable to always shut off the fuel supply, run the engine to fuel starvation and drain the tank when the equipment is not in use for more than 30 days.

ASSEMBLY

Connecting Liquid Petroleum Gas (LPG) Cylinder

1. Make sure the fuel valve on the generator is in the off position.

2. Attach the LPG hose (included) to the LPG hose connector on the side of the generator and tighten with an adjustable wrench.
   Important: DO NOT use tape or any other type of sealant to seal LPG hose connection.

3. Remove the safety plug or cap from the cylinder valve.

4. Attach the other end of the hose to the LPG connector on the cylinder and hand tighten.

5. Check all connections for leaks by wetting the fi ttings with a solution of soap and water. Bubbles which appear or bubbles which grow indicate that a leak exists. If a leak exists at a fi tting then turn off the gas valve at the tank and tighten the fi tting. Turn the gas back on and recheck the fi tting with the soap and water solution. If the leak continues or if the leak is not at a fi tting then do not use the generator and contact customer service.

NOTE

• Use only standard 20 or 30 pound capacity LP tanks with Type 1, right hand Acme threads.
• Verify the requalifi cation date on the tank has not expired.
• All new cylinders must be purged of air and moisture prior to fi lling. Used cylinders that have not been plugged or kept closed must also be purged.
• The purging process should be done by a LPG supplier. (Cylinders from an exchange supplier should have been purged and fi lled properly already).
• Always position the cylinder so the connection between the valve and the gas inlet won’t cause sharp bends or kinks in the hose.

Connecting LPG Cylinder Cont’d.

CAUTION
Do not allow children to tamper or play with the cylinder or hose connections.

CAUTION
Use approved LPG cylinders equipped with an OPD (overfi lling prevention device) valve. Always keep the cylinder in a vertical position with the valve on top and installed at ground level on a fl at surface Cylinders must not be installed near any heat source and should not be exposed to sun, rain, and dust. When transporting and storing, turn off the cylinder valve and fuel valve, and disconnect the cylinder. Plug the outlet, usually by a plastic protective cap, if one is available. Keep cylinders away from heat and ventilated when in a vehicle.

WARNING
If there is a strong smell of gas: Close off the gas supply at the cylinder. Use soapy water, which will produce a large bubble at the point of any leak, to check the hose, and connections on the cylinder valve and the generator. Do not smoke or light a cigarette, or check for leaks using a match, open fl ame source or lighter. Contact a qualifi ed technician to inspect and repair the LPG system if a leak is found, before using the generator.

Grounding

Your generator must be properly connected to an appropriate ground to help prevent electric shock.

WARNING
Failure to properly ground the generator can result in electric shock.

A ground terminal connected to the frame of the generator has been provided on the power panel. For remote grounding, connect of a length of heavy gauge (12 AWG minimum) copper wire between the generator ground terminal and a copper rod driven into the ground. We strongly recommend that you consult with a qualifi ed electrician to ensure compliance with local electrical codes.

Generator Location

Never operate the generator inside any building! (See safety warnings section). In some areas generators must be registered with the local utility company. Generators used on construction sites may be subject to local rules and regulations. Keep on a fl at, level surface. Generators must have at least 5 ft (1.5m) clearance from all combustible material. In addition they must have at least 3 ft (91.4cm) of clearance on all sides to allow for adequate cooling, maintenance and servicing. Generators should never be started or operated in ant location that will not allow for adequate cooling of the generator and/or the muffl er. Allow generators to cool before storage or transportation. Do not place the generator near any vents or intakes. Carefully consider wind and air currents when placing generator. Failure to follow the proper safety instructions may void the manufacturer’s warranty.
Failure to follow proper safety precautions may void manufacturer’s warranty.

WARNING
Do not operate or store the generator in rain, snow, or wet weather.

Using a generator or electrical appliance in wet conditions, such as rain or snow, or near a pool or sprinkler system, or when your hands are wet, could result in electrocution.

WARNING
During operation the muffl er and exhaust fumes produced will become hot. If adequate cooling and breathing space are not supplied, or if the generator is blocked or contained, temperatures can become extremely heated and may lead to fi re.

Surge Protection

CAUTION
Voltage fl uctuation may impair the proper functioning of sensitive electronic equipment.

Electronic devices, including computers and many programmable appliances use components that are designed to operate within a narrow voltage range and may be affected by momentary voltage fl uctuations. While there is no way to prevent voltage fl uctuations, you can take steps to protect sensitive electronic equipment.

1. Install UL1449, CSA-listed, plug-in surge suppressors on the outlets feeding your sensitive equipment. Surge suppressors come in single- or multi-outlet styles. They’re designed to protect against virtually all short-duration voltage fl uctuations.

OPERATION

Fuel Selector Switch
The fuel selector switch on the front panel of the generator is designed specifi cally to choose between the fuel source desired, Petrol or LPG. To select a fuel source simply slide the switch cover to either the right or left, and this will uncover the fuel valve of the fuel selected. The LPG fuel valve (A) is to the left of the switch cover. The petrol fuel valve (B) is to the right of the switch cover.

Once a fuel source has been selected, the user must turn the fuel valve to the vertical position to open the fuel valve. (1)

To turn a fuel valve to the off position the valve must be in the horizontal position. (2)

NOTE
The fuel selector switch cover is specifi cally designed not to slide to either side while a specifi c fuel has been selected and the valve is in the “ON” position. Only when the fuel valves are in the “OFF” position can the cover slide side to side.

NOTE
The fuel selector is locked into place once a “CLICK” sound is made. Only then can a fuel valve be turned to the vertical position.

Starting the Engine in ambient > 15°C (59°F) Petrol

NOTE
For LPG starting in cold ambient < 15°C (59°F) Move the choke lever to the “75% Choke” position for electric starting and “100% Choke” for recoil start. For electric start, gradually move the choke lever to the “RUN” position over a 2-10 second duration. To pull to prime for recoil start Pull with “100% Choke” 1-3 times until you feel a few combustion pulses that indicates that the engine momentarily started.

CAUTION
If the ignition switch is held down in the “Start” position longer than 5 seconds it could damage the starter.

NOTE
If the engine starts but does not run make certain that the generator is on a fl at, level surface. The engine is equipped with a low oil sensor that will prevent the engine from running when the oil level falls below a critical threshold.

NOTE
When the battery switch is in the “ON” position, the switch will light up if the battery is sending out a charge. If the switch does not light up while in the “ON” position, check that the battery connection is still good.

NOTE
The supplied 12V 15AH battery does re-charge while the engine is running, but it is also recommended that the battery be fully charged at least once per month.

Starting the Engine Cont’d.

NOTE
Observing frost on LPG containers and regulators is common during operation and normally is not an indication of a problem. As LPG vapourizes and travels from the tank to the generator engine it expands. The amount of frost that forms can be affected by the size of the container, the amount of fuel being used, the humidity of the air and other operating conditions. In unusual situations this frost may eventually restrict the fl ow of gas to the generator resulting in deteriorating performance. For example, if the tank temperature is reduced to a very low level then the rate at which the LPG vaporizes is also reduced and may not provide suffi cient fuel fl ow to the engine. This is not an indication of a problem with the generator but only a problem with the fl ow of gas from the LPG container. If generator performance seems to be deteriorating at the same time that ice formation is observed on tank valve, hose or regulator then some actions may be taken to eliminate this symptom.
In these rare situations it can be helpful to reduce or eliminate the cold fuel system effects by doing one of the following:

• Exchanging fuel tanks to allow the fi rst tank to warm up, repeating as necessary
• Placing the LPG container at the end of the generator near the handle, where engine fan air fl ows out from the generator. This air is slightly heated by fl owing over the engine. The container should not be placed in the path of the muffl er outlet.
• The container can be temporarily warmed by pouring warm water over the top of the tank.

Stopping the Engine

1. Turn off and unplug all electrical loads. Never start or stop the generator with electrical devices plugged in or turned on.
2. Let the generator run at no-load for several minutes to stabilize internal temperatures of the engine and generator.
3. Turn the Petrol Fuel Valve to the “OFF” position if operating by petrol.
4. Turn the LPG cylinder knob to the “CLOSE” or off position if operating by LPG.
5. Let the engine run until fuel starvation has stopped the engine. This usually takes a few minutes.
6. Press the ignition switch to the “OFF” position.
7. Turn battery switch to the “Off” Position.

Important: Always ensure that the Fuel Valve and the Ignition Switch are in the “OFF” position when the engine is not in use.

Stopping the Engine Cont’d.

NOTE
When turning off the generator after LPG operation, make sure the LPG cylinder knob is in the fully closed position.

NOTE
If the engine will not be used for a period of two (2) weeks or longer, please see the Storage section for proper engine and fuel storage.

Connecting Electrical Loads

1. Let the engine stabilize and warm up for a few minutes after starting
2. Plug in and turn on the desired 120/240 Volt AC single phase, 50 Hz electrical loads.
   • DO NOT connect 3-phase loads to the generator.
   • DO NOT connect 60 Hz loads to the generator.
   • DO NOT overload the generator.

NOTE
Connecting a generator to your electric utility company’s power lines or to another power source may be against the law. In addition this action, if done incorrectly, could damage your generator and appliances and could cause serious injury or even death to you or a utility worker who may be working on nearby power lines. If you plan to run a portable electric generator during an outage, please notify your electric utility company immediately and remember to plug your appliances directly into the generator. Do not plug the generator into any electric outlet in your home. Doing so could create a connection to the utility company power lines. You are responsible for ensuring that your generator’s electricity does not feed back into the electric utility power lines. If the generator will be connected to a building electrical system, consult your local utility company or a qualifi ed electrician. Connections must isolate generator power from utility power and must comply with all applicable laws and codes.

Do Not Overload Generator Capacity

Follow these simple steps to calculate the running and starting watts necessary for your purposes.

1. Select the electrical devices you plan on running at the same time.
2. the running watts of these items. This is the amount of power you need to keep your items running.
3. Identify the highest starting wattage of all devices identifi ed in step 1. Add this number to the number calculated in step 2. Surge wattage is the extra burst of power needed to start some electric driven equipment. Following the steps listed under “Power Management” will guarantee that only one device will be starting at a time.

Power Management

Use the following formula to convert voltage and amperage to watts:

Volts x Amps = Watts

To prolong the life of your generator and attached devices, follow these steps to add electrical load:

1. Start the generator with no electrical load attached
2. Allow the engine to run for several minutes to stabilize.
3. Plug in and turn on the fi rst item. It is best to attach the item with the largest load fi rst.
4. Allow the engine to stabilize.
5. Plug in and turn on the next item.
6. Allow the engine to stabilize.
7. Repeat steps 5-6 for each additional item.

NOTE
Never exceed the specifi ed capacity when adding loads to the generator.

*To be performed by knowledgeable, experienced owners or Champion Power Equipment certifi ed dealers.

Generator Maintenance

Make certain that the generator is kept clean and stored properly. Only operate the unit on a fl at, level surface in a clean, dry operating environment. DO NOT expose the unit to extreme conditions, excessive dust, dirt, moisture or corrosive vapours.

CAUTION
DO NOT use a garden hose to clean the generator. Water can enter the generator through the cooling slots and damage the generator windings.

Use a damp cloth to clean exterior surfaces of the generator. Use a soft bristle brush to remove dirt and oil. Use an air compressor (25 PSI) to clear dirt and debris from the generator. Inspect all air vents and cooling slots to ensure that they are clean and unobstructed.

Storage

The generator should be started at least once every 14 days and allowed to run for at least 20 minutes. For longer term storage, please follow these guidelines.

Generator Storage

1. Add a properly formulated fuel stabilizer to the tank.
2. Be sure all appliances are disconnected from the generator.
3. Run the generator for a few minutes so the treated fuel cycles through the fuel system and carburetor.
4. Turn the fuel valve to the “Off” position.
5. Let the generator run until fuel starvation has stopped the engine. This usually takes a few minutes.
6. The generator needs to cool completely before cleaning and storage.
7. Clean the generator according to the maintenance section.
8. Change the oil.
9. Remove the spark plug and pour about 14.8 mL (1⁄2 ounce) of oil into the cylinder. Crank the engine slowly to distribute the oil and lubricate the cylinder.
10. Reattach the spark plug.
11.  Store the unit in a clean, dry place out of direct sunlight.

DANGER
Generator exhaust contains odourless and colourless carbon monoxide gas.

To avoid accidental or unintended ignition of your remote start generator during periods of storage, the following precautions should be followed:

• When storing the generator for short periods of time make sure that the Ignition Switch, the Fuel Valve and the Battery Switch are set in the OFF position.
• When storing the generator for extended periods of time make sure that the Ignition Switch, the Fuel Valve and the Battery Switch are set in the the the OFF position and the battery leads have been disconnected from the battery.

Generator Battery

This product is equipped with an automatic battery charging circuit. The battery will receive charging voltage when the engine is running. The battery will maintain a proper charge if the unit is used on a regular basis (about once every two weeks). If it is used less frequently, the battery should be connected to a trickle charger (not included) or battery maintainer (not included) to keep the battery properly charged. If the battery is not able to start the engine, it can be started by manually pulling the engine recoil cord. If the battery voltage is extremely low, the charging circuit may not be able to re-charge the battery. In this case, the battery must be connected to a standard automotive style battery charger for re-charging before it can be used.

Disconnect the Battery

1. Remove the protective cover from the black/negative battery lead.
2. Disconnect the black/negative lead from the black/negative terminal on the battery and store the cap screw (M5x10) and nut (M5).
3. Repeat steps 1-2 for the red/positive battery lead.
4.  Store the battery in a cool, dry place.

Charge the Battery

For a generator equipped with batteries for electric starting, proper battery maintenance and storage should be followed. An automatic battery charger (not included) with automatic trickle charging capability should be used to charge the battery. Maximum charging rate should not exceed 1.5 amps. Follow the instructions included with the battery charger. The battery should be fully charged at least once per month.

NOTE
A Float Charger will maintain the battery condition over long storage periods.
