WINDING UP MOWING THREADS

There are three different procedures for winding STIHL mowing threads onto a mowing head:

  • Standard mowing heads: Remove the mowing head from the brush cutter and open it. Wind the mowing thread onto the now exposed spool. Arrows will help you wind the mower thread in the correct direction. If you do not want to do this yourself, a STIHL dealer in your area will be happy to help.
  • Comfort mowing heads: Here, the thread is wound from the outside. Simply insert the desired length of mowing thread into the mower head and then wind the mowing thread around the thread spool by turning the lower end of the mower head. Caution. The mowing thread should protrude from the mowing head on both sides for the same length before winding. By the way, you can recognize mowing heads with this convenience feature by the letter "C" in the model name.
  • A third variant is equally suitable for standard and comfort mower heads: Open the mowing head and insert a pre-filled reel.

WHICH MOWING THREAD TO WIND FOR WHAT?

At STIHL you will find the right mowing string for every challenge. The "Round, Quiet" mowing filaments are fitted as standard in the mowing heads for STIHL power scythes. With them, you can achieve optimum results in most working environments with reduced noise levels. STHIL has the right mowing string for a wide variety of applications. Ask your dealer for the right thread with the correct diameter to fit your needs and in your mower head. The mowing threads differ not only in the shape of the thread spool but also in their diameter. 

By the way: For better recognition and orientation, the mowing threads have different colors, each of which stands for a specific diameter. For example, red mowing threads always have a diameter of 2.7 millimeters. You can find out which mowing filament is best to wind up for your upcoming work and which color you can recognize it by in the following guide:

PREPARE AND PROPERLY STORE MOWING THREAD FOR WINDING

Last but not least, a note on proper storage and optimal preparation of your mowing filament: We recommend soaking the mowing filament in water for 24 hours before use. Mowing threads lose moisture and thus elasticity over time. By soaking them in water, they get both back and don't wear out as much. By the way, you do not need to unwind the thread for this: you can put the spool together with the wound mowing thread directly into the water. Thanks to this procedure, you also don't need to worry about storing your thread: you can simply leave it in your brush cutter with a clear conscience until the next time you use it.

CHANGING THE CUTTING TOOL OF POWER SCYTHES WITH MOWING HEAD

1. PREPARATION
Switch off the device. In the case of a gasoline-powered device, pull out the spark plug connector. In the case of a motor scythe with a rechargeable battery, remove the battery from the battery compartment or pull the connecting cable out of the socket.

Please check whether the correct guard approved for the cutting tool is fitted. Hold the motorized scythe so that the holder for the cutting tool points upwards.

2. BLOCK SHAFT
Push the plug pin or the offset screwdriver into the hole in the gear unit. Now turn the shaft until the plug pin engages and the shaft locks.

3. DISMANTLE MOWING HEAD
Turn the mowing head clockwise until it comes off. Now you can replace it with a new one.

4. ATTACH MOWER HEAD
Turn the mowing head counterclockwise until it rests on the shaft.

5. TIGHTEN MOWING HEAD, PULL OFF TOOL
Tighten the mowing head with the shaft blocked. Then pull off the tool again to block the shaft.

SUMMMARY

  • There are various mowing heads, mowing threads, and thread spools from STIHL that are suitable for different applications.
  • You can wind up a mowing thread very easily: Either open the mowing head for this purpose or, thanks to the comfort function, simply insert it and wind up the mowing thread by turning it. Another option is to use a pre-filled spool.
  • You should soak each mowing string in water for 24 hours before winding and using it - this way it retains the necessary moisture and elasticity.
