Proper lubrication of the chain while in operation reduces
friction between the chain and the guide bar to a minimum
and assures a longer service life.
• Use bar and chain oil of high quality for this purpose.
• Do not use used or reclaimed oil to avoid various oiler
problems.
• Use ECHO bar and chain oil.
• When ECHO bar and chain oil is not available: Use motor
oil, etc.
• Use bar and chain oil of the following grades:
• SAE No. 30....in summer
• SAE No. 10....in winter or when cutting resinous trees.
• When refueling, also refill chain oil.
Moving parts can amputate fingers or cause severe injuries. Keep hands, clothing and loose objects
away from all openings. Always stop engine, disconnect spark plug, and make sure all moving parts
have come to a complete stop before removing obstructions, clearing debris, or servicing unit.
Engine exhaust IS HOT, and contains Carbon Monoxide (CO), a poison gas. Breathing CO can cause
unconsciousness, serious injury, or death. Exhaust can cause serious burns. ALWAYS position unit
so that exhaust is directed away from your face and body.
