Stihl FS38 fuel line size
The Stihl FS38 is a petrol line trimmer that uses a ready-mixed fuel for all Stihl engines. This means that there is no need to worry about getting the fuel-to-oil ratio correct. The recommended fuel-to-oil ratio for most two-stroke engines is 50:1, which can be achieved by adding a small bottle of Stihl oil to a gallon of unleaded petrol. This fuel mixture is essential for optimal performance and prolonging the life of your tool.
The Stihl FS38 comes with a domestic 2-year warranty and ongoing service and support from your local Stihl shop. It features a button that, when pushed, delivers fuel to the carburettor, making the machine easier to start. The mowing head is suitable for trimming work, with double mowing lines that automatically extend when the head is tapped on the ground. The correct diameter of the nylon line for this model is 2mm, and it is important to not use excess nylon as it will reduce rotation speed and power.
It is important to note that if you are not using your machine regularly, you should not leave fuel sitting in the tank. Additionally, Stihl continues to make spare parts for 10 years after they have retired a product from production, making it a great long-term investment.
