The STIHL BGA 200 comfort carrying system can only be used with a STIHL AR backpack battery. It consists of two components: a suspension device on the STIHL BGA 200 battery blower, and a mounting plate which you can attach to the belt of your STIHL AR L carrying system in conjunction with an AR backpack battery such as the STIHL AR 3000 L. This means that you can use the STIHL BGA 200 as a 2-in-1 power tool in two working modes: you can carry it in your hand or, when needed, hook it to the plate positioned on the side of your body. Depending on your preferred working method, the STIHL comfort carrying system allows you to quickly switch between these two modes. This means that you can work for longer periods with little effort. Once the STIHL BGA 200 is hooked in, you can change your hand position at any time using the second handle, making your work even more comfortable.The STIHL BGA 200 battery leaf blower comes with the carrying system as standard. STIHL AR batteries and the STIHL AR battery carrying system are not included in the scope of delivery.
