• Use premium unleaded gasoline with a minimum octane rating of 90. If lower octane gasoline is
used, engine temperature will increase which can result in a piston seizure and damage to the
engine.
• Always provide adequate ventilation when handling fuel.
• Use caution when handling gasoline. Avoid direct contact with skin or inhaling fuel vapor.
FUEL MIXING
• Always mix gasoline and oil in a clean container intended for use with fuel.
• Keep fuel container closed tightly to prevent moisture from getting into the fuel.
• Always begin mixing fuel by adding half the amount of gasoline to be used. Then add the correct
amount of two-stroke oil for 25:1 mixture and finish filling the container with gasoline.
• Do not mix more than one month's supply of fuel. This helps prevent the separation of the
two-stroke oil from the gasoline (varnishing).
• If the saw is not used for an extended period of time (3 months) the fuel tank should be emptied
and cleaned.
FUELING
• Always shut off the saw before fueling.
• Before fueling, clean the area around fuel cap to prevent dirt from contaminating the fuel.
Contamination of the fuel tank can lead to saw malfunction.
• Thoroughly mix the fuel in it's container before fueling.
• Slowly open the fuel cap to release any pressure that may have built-up in the tank.
• After adding fuel, tighten the fuel cap carefully and secure with a wrench.
