The cutting line is the heart of the grass trimmer. If the spool no longer contains any wire, you will need a new thread so that you can use the device properly again. These instructions explain how to change the thread in the grass trimmer in just a few simple steps.
How do I change the thread on a grass trimmer?
To change the thread in the grass trimmer, secure the device, open the thread head, remove the empty spool, bend the new wire in the middle, insert it into the guide, wind both halves of the thread clockwise and insert the ends into corresponding slots.
Change the entire spool or just the thread?
Find out in advance whether your grass trimmer is even designed to change the line. Inexpensive models are designed so that a completely new spool is required each time the cutting line is used up. The cheap purchase turns out to be expensive in retrospect because a new thread head costs more than a simple wire.
What makes matters worse is that when you buy replacement coils, you are tied to the manufacturer because the coils are not compatible with third-party devices. What is advantageous is that replacing a thread spool can be done in no time using the operating instructions.
Changing thread made easy – this is how you wind the wire correctly
Thanks to the well-thought-out concept, the spools on high-quality grass trimmers are reused. The only thing on the shopping list is a new cutting line. The operating instructions (€39.00 at Amazon) reveal the correct thread thickness and length. You can purchase the right wire inexpensively at any hardware store. How to wind the thread correctly:
- Secure the lawn trimmer: pull out the power plug, remove the battery or remove the spark plug cable
- Open the thread head by pressing on the two side clamps
- Pull off the cover and take out the empty spool
- Kink the new wire in the middle and hook it into the guide of the double thread spool
- Wind both thread halves parallel to each other in a clockwise direction
- Put each of the two ends into the corresponding slots of the thread head
Please make sure that each of the two thread ends protrudes a maximum of 10 to 20 cm. Pull each wire tight before putting the lid on.
Tip
If the thread on the grass trimmer breaks, you don't necessarily need a new wire. With a little sensitivity you can repair the cutting line. Find the thread ends in the spool, pull them out and thread the wire ends back into the slots on the edge. To make the thread last longer, you should soak it in water for 24 hours before using it again.
