After mowing the lawn, trimming the edges of your property is essential for a neat appearance. The STIHL string trimmer is a great tool for the job, but it requires regular maintenance to work efficiently. Knowing how to take apart the trimmer head to replace the trimmer line is important.
Types of STIHL Trimmer Heads
STIHL trimmers have three common head models: Autocut, Autocut Easy Spool, and Trimcut. Before disassembling any parts, let the trimmer cool down if it has a rotating head to avoid injury. For gas models, disconnect the spark plug wire from the spark plug. Check the trimmer head for the model number before disassembly, as each model is slightly different. Flip the trimmer over to access the head once it has cooled down.
Removing the Autocut Head
The Autocut model has a tapping cover that is held in place by tabs on each side of the head. Press each tab firmly, push it inward, and then up towards the head to disengage the cover. Slowly pull the cover to remove it and access the spool inside. Press down on the center knob and turn it counterclockwise to remove the spool.
Disassembling the Trimcut Head
The Trimcut model has a star nut that holds the spool in place. Twist the nut counterclockwise to remove it and access the spool. This model does not have a tapping cover, so the spool is easily accessible.
Dismantling the Autocut Easy Spool Head
The Autocut Easy Spool model has a large nut that looks like a knob on the bottom of the head. Twist the nut counterclockwise to remove it and access the spool. Pay attention to the spring in the center of the spool to avoid losing it, as the tool will not function correctly without it.
Cleaning the STIHL String Trimmer
When replacing the trimmer line, take the opportunity to clean the trimmer to ensure maximum efficiency. Regular cleaning of your lawn care tools is essential to maintain proper functionality.
To clean the trimmer head, use a dry cloth to remove any dirt or grass that may have entered the cavity. Depending on the model, you may also wipe the cover or nut to make reassembly easier. If the STIHL trimmer spool is empty and needs to be refilled with new line, wipe the empty spool as well.
