FAQ
Q: How do I confirm this trimmer head fits my brushcutter?
A:Check your trimmer's shaft type. This head fits most straight-shaft trimmers and brushcutters with a 25.4mm (1 inch) center hole. It will not fit curved-shaft machines. You will need the standard blade washers and either a left-hand thread nut or bolt for your specific machine.
Q: What line diameter can I use with this head?
A: This head is compatible with 2.4mm line as standard. Some models also accept line diameters up to 3.0mm or 3.5mm for heavier applications. Always check the specific head's specifications before using thicker line.
Q: How do I load the trimmer line?
A: Cut the line to the desired length (typically 250-300mm). Feed the line through the center hole and loop it back, then wind it on in the direction the head turns. Push the ends into the securing slots and trim to even length. Line can be advanced by pulling it out of the slots.
