MAINTENANCE

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. Wear gloves to protect hands from sharp edges and 
hot surfaces.

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