! Caution

:Injuries

￿ When performing equipment check and maintenance, always stop the engine.

! Caution

:Fire ￿ Burns

￿Battery may emit some combustible gas, so keep it away from fire and sparks.

￿Temperature around muffler and exhaust can get extremely high. Keep any inflammable items (such as fuel, gas, paint, etc.) away from the equipment.

￿When checking engine oil or changing oil, always stop the engine, and wait until the engine cools down. If you open either the oil gauge or the oil filler cap during operation, hot oil may cause some injury.

Follow the guideline below, when performing any troubleshooting. If you cannot resolve the problems by this troubleshooting guide, contact the authorized distributor or our engineering section to request the repair.
