MAINTENANCE AND CARE
Your ECHO chain saw is designed to provide many hours of trouble free service. Regular scheduled maintenance will help your
chain saw 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 ask your ECHO dealer for repairs.
