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.
SKILL LEVELS
Level 1 = Easy to do. Most required tools come
with unit.
Level 2 = Moderate difficulty. Some specialized
tools may be required.
ECHO offers REPOWER™ Maintenance Kits and
Parts to make your maintenance job easier. Just
below each task heading are listed the various part
numbers required for that task. Ask your ECHO
dealer for these parts.
IMPORTANT
Time intervals shown are maximum.
Actual use and your experience will determine
the frequency of required maintenance.
