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.

• 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.
