Chain lubricant
Proper lubrication of the chain while in operation
reduces the friction to a minimum between the
chain and the guide bar, and assures faster cutting
and longer bar and chain life.
• The QuikVent™ system should be used only with
special ECHO detergent bar and chain oil.
Refer to page 25 for accessory part number.
• When refilling fuel mixture, fill up chain oil at the
same time.
