CHAIN LUBRICANT
Proper lubrication of the chain while in operation 
reduces friction between the chain and the guide 
bar to a minimum and assures a longer service life.
•  Use bar and chain oil of high quality for this 
purpose.
•  Do not use used or reclaimed oil to avoid various 
oiler problems.
•  Use ECHO bar and chain oil.
•  Use bar and chain oil of the following grades: 
SAE No. 30 ....... in summer
