Gasoline
oThe fuel used for operating the Echo
451 VL is a mixture of gasoline and
Kioritz Echo Off.
The gasoline-oi] ratio is 20 to 1.
I_otes:
"_ Make sure that the mixing ratio is 20 to 1. Any other ratio will bring
about engine troubles.
¢r If Kioritz Echo Oil is not obtainable, use motor oil for 2-cycle engines.
Do not use any oil other than Kioritz Echo Oil or motor oil for 2-cycle
engines.

Lubricant
Appropriate lubrication to the chain in operation will reduce to the
minimum the friction between the chain and bar, and will assure a longer
service life. For lubrication, apply Kioriez chain oil.
Notes;
¢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)
