CHAIN LUBRICANT
Proper lubrication of the chain while in operation
reduces the 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.
• When ECHO bar and chain oil is not available:
Use motor oil, etc.
• Use bar and chain oil of the following grades:
SAE No. 30 ....... in summer
SAE No. 10 ....... in winter or when cutting
resinous trees.
• When refueling, also refill chain oil.
