Chain Lubricant
Proper lubrication of the chain
while in operation minimizes
friction between the chain, the
guide bar and sprocket. Use
ECHO genuine chain oil or ECHO
recommended chain oil specially
formulated for bars and chains for
proper lubrication. These oils
contain tackifiers, anti-aging and
anti-oxidizing agents.
Consult your ECHO dealer for the proper chain oil. Never use waste or
reclaimed oil to avoid various malfunctions of the oil system, chain and
guide bar. Lubrication problems caused by the use of improper oil will void
the warranty.
Especially, vegetable based chain oil quickly turns to resin and adheres to
oil pump, chain and guide bar. It causes malfunctions and shorten product
life. Flush chain oil system with mineral or chemical based chain oil after
use, if it is required to use vegetable oil due to local / municipal restrictions
or any other reason.
For a short time of emergency operation, fresh SAE 10W-30 motor oil can
be used.
