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.
