!Taking the following precautions, will lessen the risk of fire.

•Do not smoke or place warm objects in the vicinity of the fuel.

•Always shut off the engine before refuelling.

•Slowly open the fuel cap, when filling fuel, so that possible overpressure is slowly released.

•Tighten the fuel cap carefully after fuelling.

•Always move the saw from the fuelling area before starting.

Clean around the fuel cap. Clean the fuel and chain oil tanks regularly. The fuel filter should be changed at least once a year. Contamination in the fuel tanks causes malfunction. Make sure the fuel is well mixed by shaking the container before fuelling. The volume of chain oil and fuel tanks are adjusted to each other. Therefore, always fill chain oil and fuel at the same time.
