Fortunately, I have the right one battery pack with my cordless screwdriver, so Frohgemut to work, and the long Astsägeblätter are delivered perfectly. already at the 5th forearm thick branch circuit is empty with Funny and battery, battery charge, and the spare battery in and carry on, again only 5 branches and end. Not yet charged battery and I Sauer. so that is the hazelnut nix, chainsaw out and gas, now the branches still small make (battery is full again) and again the battery 5-6 branches going grad times far. either eats the machine too much power or I'm just too impatient to return it and buy a cable device!
