minimum the friction between the chain and bar, and will assure a longer

service life. For lubrication, apply Kioriez chain oil.

¢r Do not use waste or reclaimed oil which will cause varioustroubles.

_" If Kioritz chain oil is unavailable at your nearby shop, use motor oil

having the following grade:

SAE # 30 ......... in summer

SAlE # 10 ......... in winter (or when cutting resinous trees)
