• Carefully check fuel pipes and joints for looseness and fuel leakage. Leaked fuel creates a potentially dangerous situation.
  • Check bolts and nuts for looseness. A loose bolt or nut may cause serious engine trouble.
  • Check the fuel level and refill if necessary. Take care not to overfill the tank.
  • Wear snug fitting working clothes when operating the engine. Loose aprons, towels, belt, etc., may be caught in the engine or drive train, causing a dangerous situation.


  • The fuel tank capacity is approx. 1.1 L
  • Use the mixture fuel prepared by mixing gasoline and exclusive 2-cycle oil at a ratio of 25 : 1, or the 2-cycle fuel now available on the market.
  • For break-in of a new engine, use mixture fuel of gasoline 20 : 1, 2-cycle engine oil, during first ten hours of operation.
  • Close fuel cock before refilling fuel tank.
  • Use fuel strainer provided at the fuel filler whenever adding oil.
  • Wipe off spilt fuel before starting engine.




  • Never inhale exhaust gasses. They contain carbon monoxide, a colorless, odorless and extremely dangerous gas which can cause unconsciousness or death.
  • Never operate the engine indoors or in a poorly ventilated area, such as tunnel, cave, etc.
  • Exercise extreme care when operating the engine near people or animals.
  • Keep the exhaust pipe free of foreign objects.


  • Be sure to stop the engine prior to refueling.
  • Do not overfill the fuel tank.
  • If fuel is spilt, wipe it away carefully and wait until the fuel has dried before starting the engine.
  • After refueling, make sure that the fuel cap is secure to prevent spillage.


  • Do not operate while smoking or near an open flame.
  • Do not use around dry brush, twigs, cloth rags, or other flammable materials.
  • Keep the engine at least 3 feet (1 meter) away from buildings or other structures.
  • Keep the engine away from flammables and other hazardous materials (trash, rags, lubricants, explosives).


  • Place the protective covers over the rotating parts. If rotating parts such as the drive shaft, pulley, belt, etc. are left exposed, they are potentially hazardous. To prevent injury, equip them with protective covers or shrouds.
  • Be careful of hot parts. The muffler and other engine parts become very hot while the engine is running or just after it has stopped. Operate the engine in a safe area and keep children away from the running engine.
  • Never make adjustments on the machinery while it is connected to the engine, without first removing the ignition cable from the spark plug. Turning over the machinery by hand during adjusting or cleaning might start the engine, and machinery with it, causing serious injury to the operator.


  • Operate the engine on a stable, level surface free of small rocks, loose gravel, etc.
  • Operate the engine on a level surface, If the engine is tilted, fuel spillage may result.
  • Be careful of fuel spillage when transporting the engine. Tighten the fuel tank cap securely and close the fuel strainer cock before transport.
  • Do not move the engine while in operation when it has been removed from the equipment.
  • Keep the unit dry (do not operate it in rainy conditions).
