Frequently Asked Questions What protective gear should I use with the MTR 20 Li? When operating this trimmer, it’s essential to wear clothing that protects your legs and face from any debris that might be thrown. It is always recommended to wear sturdy, long trousers and a protective visor or safety glasses. What maintenance does this cordless trimmer require? To ensure the machine functions correctly and to maximise its lifespan, regular cleaning is recommended. Based on your frequency of use, you should clean the battery housing, its contacts, and the cutting head assembly (trimmer head and guard) where dirt and grass clippings can build up. Always consult the user manual for specific maintenance tasks. What is this trimmer designed to cut? This machine is perfectly suited for tidying up lawn edges and cutting overgrown grass in areas your lawnmower cannot reach, such as around trees, fence posts, walls, and washing poles. How do you feed more line from the cutting head? This model features an automatic single-line feed head. As the line wears down, the head automatically releases more line to maintain the correct cutting length, ensuring continuous operation without manual adjustment. What should I do if the line stops feeding out? If the line fails to feed, there are two common causes. Firstly, the line spool may be empty and requires replacement. Secondly, the line inside the head might have become tangled or caught on its own windings. In this case, you can open the head and re-spool the line correctly.
