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. Allow unit to cool before performing service.

Your ECHO trimmer is designed to provide many hours of trouble free service. Regular scheduled maintenance will help 

your trimmer achieve that goal. If you are unsure or are not equipped with the necessary tools, you may want to take 

your unit to an ECHO Service Dealer for maintenance.  To help you decide whether you want to DO-IT-YOURSELF or 

have the ECHO Dealer do it, each maintenance task has been graded. If the task is not listed, see your ECHO Dealer for 

repairs.
