FUEL STATEMENT
GASOLINE-Use 89 Octane [
] gasoline or
gasohol known to be good quality.
Gasohol may contain maximum 10% ethyl (grain)
alcohol or 15% MTBE (methylteriary-butyl ether).
Gasohol containing methyl (wood) alcohol is not
approved.
TWO-STROKE OIL - Use 50 : 1 two-stroke ECHO
oil only.
Engine problems due to inadequate lubrication
caused by failure to use 50 : 1 ECHO oil will void
the warranty on your ECHO product.
MIXING - Mix oil and gasoline/gasohol according to
the instructions on the ECHO oil label.
IMPORTANT
Stored fuel ages.
Do not mix more fuel than you expect to use in
thirty (30) days, ninety (90) days when a fuel
stabilizer is added.
Stored two-stroke fuel may separate.
ALWAYS shake fuel container thoroughly before
each use.
CAUTION
Whenever opening up the fuel tank, always
loosen the cap very slowly and wait for the
tank pressure to be equalized before removing
the cap.
CHAIN LUBRICANT
Proper lubrication of the chain while in operation
reduces friction between the chain and the guide
bar to a minimum and assures a longer service life.
• Use ECHO bar and chain oil of high quality
for this purpose.
• Do not use used or reclaimed oil to avoid
various oiler problems.
• When refueling, also refill chain oil.
