MAINTENANCE AND CARE

IMPORTANT

Time intervals shown are maximum.

Actual use and your experience will determine

the frequency of required maintenance.

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.

Level 3 = Experience required. Specialized tools

are required. ECHO recommends that

the unit be returned to your ECHO dealer

for servicing.

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.
