When you have finished using the mower, remove the battery and clean using a damp cloth or soft brush. Always wear gloves and tie back long wear when cleaning or maintaining your mower.

#2Storing your RMA 443 TC

Store your RMA 443 TC in a clean and dry area away from children at all times. Don't forget you can fold the handle over and put the grass box on top so it takes up less space.

#3Looking after your battery

Don't use a damp or wet battery in your RMA 443 TC and avoid using them in extreme temperatures (very hot or very cold). Find out more about looking after your battery on our blog.

#4Using a mulching kit

You can also buy a mulching kit for your RMA 443 TC. This means that instead of collecting the grass clippings in the catcher box, you use the mulching kit to cut the clippings finely and drop them back on to the lawn as a natural fertiliser. Find out more about mulching on the STIHL Blog.

#5Leaves on the lawn

Did you know you can use your RMA 443 TC to collect and shred leaves on your lawn? Switching off the eco mode means that the blade speed does not drop and so the mower can lift leaves with ease.
