Catalytic mufflers operate at extremely high temperatures. Muffler area must be kept clean. Do not perform mainte-

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.
