OPERATION CS-4910 2-Stroke engine oil contains petroleum distillates and other additives that may be harmful if swallowed. Heated oil can release vapors that can cause flash fire, or ignite with explosive force. Read and follow the oil manufacturer’s instructions, and observe all safety warnings and precautions for handling flammable liquids. For more detailed safety and first aid information, visit www.echo-usa.com for a copy of the Material Safety Data Sheet. ◆ KEEP OUT OF REACH OF CHILDREN.
CS-4910 ◆ ◆ OPERATION Inspect for fuel leakage. If fuel leakage is found, do not start or operate unit until leakage is repaired. Move at least 3 m (10 ft.) from refueling location before starting the engine. Gasoline vapor is heavier than air, and can travel along the ground to nearby sources of ignition such as electrical motors, pilot lights, and hot or running engines.
OPERATION CS-4910 Stored two-stroke fuel can separate. ALWAYS shake fuel container thoroughly before each use. Used oil and gasoline, and soiled towels are hazardous waste materials. Disposal laws vary by locality. Units equipped with a momentary STOP Switch automatically return to RUN position. Engine can start unintentionally. Always remove spark plug lead from spark plug before assembling or performing maintenance procedures, otherwise, serious personal injury can result.
