•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 cut-off 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 cut-off 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 cut-off 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.
