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.
