BEFORE OPERATION

ARE YOU READY TO GET STARTED?

Your safety is your responsibility. A little time spent in preparation will significantly reduce your risk of injury.

Knowledge

Read and understand this manual. Know what the controls do and how to operate them.

Familiarize yourself with the generator and its operation before you begin using it. Know how to quickly shut off the generator in case of an emergency.

If the generator is being used to power appliances, be sure that they do not exceed the generator's load rating (see page 41).

IS YOUR GENERATOR READY TO GO?

For your safety, to ensure compliance with environmental regulations, and to maximize the service life of your equipment, it is very important to take a few moments before you operate the generator to check its condition. Be sure to take care of any problem you find, or have your servicing dealer correct it, before you operate the generator.

WARNING

Failure to properly maintain this generator, or failing to correct a problem before operation, could result in a significant malfunction.

Some malfunctions can cause serious injuries or death.

Always perform a pre-operation inspection before each operation and correct any problems.

To prevent a possible fire, keep the generator at least 1 meter (3 feet) away from building walls and other equipment during operation. Do not place flammable objects close to the engine.

Before beginning your pre-operation checks, be sure the generator is on a level and firm surface and the MAIN switch is in the OFF position.

Check the Engine

  • Before each use, look around and underneath the engine for signs of oil or gasoline leaks.
  • Check the engine oil level (see page 54). A low engine oil level will cause the Oil Alert system to shut down the engine.
  • Check the air filters (see page 57). Dirty air filters will restrict air flow to the fuel system, reducing engine and generator performance.
  • Check the fuel level (see page 52). Starting with a full tank will help to eliminate or reduce operating interruptions for refueling.

Battery Maintenance Cover

Never operate the generator with the battery maintenance cover open, as poor engine and generator performance will result.

NOTICE

Depending on the region where you operate your equipment, fuel formulations may deteriorate and oxidize rapidly. Fuel deterioration and oxidation can occur in as little as 30 days and may cause damage to the fuel system. Please check with your servicing dealer for local storage recommendations.

Gasoline will oxidize and deteriorate in storage. Old gasoline will cause hard starting, and it leaves gum deposits that clog the fuel system. If the gasoline in your generator deteriorates during storage, you may need to have the fuel system components serviced or replaced.

The length of time that gasoline can be left in your fuel tank without causing functional problems will vary with such factors as gasoline blend, your storage temperatures, and whether the fuel tank is partially or completely filled. The air in a partially filled fuel tank promotes fuel deterioration. Very warm storage temperatures accelerate fuel deterioration. Fuel deterioration problems may occur within a few months, or even less if the gasoline was not fresh when you filled the fuel tank.

Draining the Fuel Tank

WARNING

Gasoline is highly flammable and explosive.

You can be burned or seriously injured when handling fuel.

  • Stop the engine and let it cool before handling fuel.
  • Keep heat, sparks and flame away.
  • Handle fuel only outdoors.
  • Keep away from your vehicle.
  • Wipe up spills immediately.

Unscrew the fuel tank cap, remove the fuel filter, and empty the fuel tank into an approved gasoline container. We recommend using a commercially available gasoline hand pump to empty the tank. Do not use an electric pump. Siphon the gasoline by inserting the tip of the hand pump into the side of the pump guard. Reinstall the fuel filter and the fuel tank cap.

FUEL TANK CAP FUEL FILTER HAND PUMP PUMP GUARD

Engine Oil

  1. Change the engine oil (see page 55).
  2. Remove the spark plug (see page 59).
  3. Pour a teaspoon (5 cm ^4 ) of clean engine oil into the cylinder.
  4. Pull the starter rope several times to distribute the oil in the cylinder.
  5. Reinstall the spark plug (see page 60).
  6. Slowly pull the starter grip until resistance is felt. At this point, the piston is coming up on its compression stroke and both the intake and exhaust valves are closed. Storing the engine in this position will help to protect it from internal corrosion. Return the starter grip gently.

Battery

Charge the battery before storing the generator (see page 65).

STORAGE PRECAUTIONS

If your generator will be stored with gasoline in the fuel tank, it is important to reduce the hazard of gasoline vapor ignition.

Select a well ventilated storage area away from any appliance that operates with a flame, such as a furnace, water heater, or clothes dryer. Also avoid any area with a spark-producing electric motor, or where power tools are operated.

If possible, avoid storage areas with high humidity, because that promotes rust and corrosion.

Place the generator on a level surface. Tilting can cause fuel or oil leakage.

With the engine and exhaust system cool, cover the generator to keep out dust. A hot engine and exhaust system can ignite or melt some materials.

Do not use a plastic sheet as a dust cover. A nonporous cover will trap moisture around the generator, promoting rust and corrosion.

Fully charge the battery. Recharge the battery once a month (see page 65).

REMOVAL FROM STORAGE

Check your generator as described in the BEFORE OPERATION chapter of this manual (see page 29).

If the generator was stored for 1 year or longer, drain the fuel tank (see page 68) and refuel with fresh gasoline. If you keep a container of gasoline for refueling, be sure that it contains only fresh gasoline. Gasoline oxidizes and deteriorates over time, causing hard starting.

If the cylinder was coated with oil during storage preparation, the engine may smoke briefly at startup. This is normal.

TRANSPORTING

If the generator has been running, allow the engine to cool for at least 15 minutes before loading the generator on the transport vehicle. A hot engine and exhaust system can burn you and can ignite some materials.

Keep the generator level when transporting to reduce the possibility of fuel leakage.

When using ropes or tie-down straps to secure the generator for transportation, be sure to only use the frame bars as attachment points. Do not fasten ropes or straps to any portions of the generator body or the folding handle.

When transporting the generator:

  • Do not overfill the tank.
  • Do not operate the generator while it is on a vehicle. Take the generator off the vehicle and use it in a well ventilated place.
  • Avoid a place exposed to direct sunlight when putting the generator on a vehicle. If the generator is left in an enclosed vehicle for many hours, high temperature inside the vehicle could cause fuel to vaporize resulting in a possible explosion.
  • Do not drive on a rough road for an extended period with the generator on board. If you must transport the generator on a rough road, drain the fuel from the generator beforehand.

  • Use a hoist and attach it on the hanger (optional parts) of your generator to lift it up for transportation.
  • When you are to lift up your generator with your assistants by hands, take care not to lift it up by holding the handle or rear bar of the generator. Be sure to lift up the generator by holding the holding part (shaded areas in the figure below).

According to EUROPEAN STANDARD EN ISO 8528-13

Carrying the generating set is considered that a 140 kg set should be provided with the means of carrying by 4 persons.

“the figures quoted are emission levels and are not necessarily safe working levels. Whilst there is a correlation between the emission and exposure levels, this cannot be used reliably to determine whether or not further precautions are required. Factors that influence the actual level of exposure of work-force include the characteristics of the work room, the other sources of noise, etc. i.e. the number of machines and other adjacent processes, and the length of time for which an operator is exposed to the noise. Also the permissible exposure level can vary from country. This information, however, will enable the user of the machine to make a better evaluation of the hazard and risk”.
