all openings. Always stop engine, disconnect spark plug, and make sure all moving parts have come to a com-

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.
