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

your blower 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 task is not listed, see your ECHO Dealer for repairs.
