According to, the AutoCut EasySpool head is designed for speedy loading; you don’t even need to disassemble it to replace the string.

  1. Turn off the trimmer and remove the spark plug’s boot to prevent inadvertent ignition. In order to reach the trimmer head, place the trimmer on a flat surface and flip it over.
  2. Take off the cap from the head. If you have an AutoCut or SuperCut head, detach the cover by pressing the two tabs on the side of the cover while lifting it off. Turn the star nut on the top of the TrimCut head counterclockwise to unscrew it, as it has reverse threads, then remove the nut.
  3. Remove the spool from the head. Push down and spin it 90 degrees counterclockwise to release it if it does not release readily.
  4. Remove the old string and remove any grass or other debris. Using a tape measure and scissors, cut two pieces of fresh thread from a roll that are equal in length. Use the appropriate string diameter for your head. Consult your trimmer head’s owner’s handbook or the Stihl website for the maximum length of string that may be cut, as this varies by model.
  5. Insert the end of one of the string lengths into one of the retention holes in the hub of the spool. Choose one of the two holes in the part of the hub closest to the top of the spool where the notches are situated. The string should be wound in the direction indicated by the arrow on the bottom of the spool. When there are 5 inches remaining, thread the string through one of the notches.
  6. Insert the end of the second string into the opposite holding hole utilized for the first string. When there are five inches remaining, wind the second string in the same manner and insert the end into the notch on the other side of the spool.
  7. Replace the spool in the head of the trimmer. If you have an AutoCut or SuperCut head, align the notches on the spool with those on the head, then press down and move the spool slightly counterclockwise to secure it. Feed the string through the head’s notches, then snap on the lid. If you possess a TrimCut head, thread the strings through the cover’s holes, replace the cover, and tighten the star nut. Remember that the nut must be tightened by turning it counterclockwise.

What Size String Does a Gas-Powered Stihl String Trimmer Utilize? By Chris Deziel Updated on December 27 Stihl has been in business since 1926 and began selling string trimmers not long after George Ballas designed the first one in the early 1970s. The firm has produced a number of replaceable trimmer heads that are compatible with several of its trimmers.

To get the greatest performance out of a head and to prevent overloading the trimmer, you must use the proper string, which Stihl and other manufacturers provide. The bulk of the 48 trimmer models currently listed on Stihl’s website are gas-powered; just one type is electric and two are battery-powered.

Many gas-powered types are acceptable for domestic usage, while others are only meant for commercial applications. The majority of heavy-duty commercial versions, as well as certain residential models, can accommodate cutting heads with blades, and all trimmers are compatible with Stihl’s string trimmer heads.2014 versions of trimmer heads include the AutoCut, SuperCut, FixCut, and TrimCut.

Additionally, the AutoCut head is available in an easy-loading variant known as the Easyspool AutoCut head. Trimmer string typically has a circular cross-section with diameters ranging from 0.065 to 0.130 inches and beyond. Wider string is more durable, but it requires more effort from the trimmer. In addition, the size of the perforations on the trimmer head frequently restricts the size of string that may be used.

It is difficult to fit string through holes that are too small for it, and more critically, the string will bind and not progress correctly. In contrast, if you choose string that is too narrow, the trimmer will likely not function to its full capacity.

Only one of the four available Stihl trimmer head types, the FixCut, can use 0.130-inch string. This is because the string is not coiled around a spool; you must manually replace it as it runs out. The usual string diameter for the TrimCut head is 0.105 inches, although 0.095-inch string may be installed on this head.

Check the trimmer head’s user manual if you’re unsure if your AutoCut head requires 0.095- to 0.105-inch string or 0.080- to 0.095-inch string. The SuperCut head is only compatible with 0.095-inch string. In addition to traditional string with a circular cross-section, Stihl offers a variety of alternative options.

Quiet Line features an aerodynamically constructed spiral cross section for quiet operation in densely populated areas. Stihl manufactures both square and pentagon cross-section line, which is superior to round line for cutting weeds. The firm also sells string trimmer heads with an X-shaped cross section under the brand name X-Line for circumstances requiring optimum cutting power.
