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. 

ECHO offers

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.
