I just purchased a Husqvarna model 125 B leaf blower at Lowe's. I read the directions and put the blower tubes on then gased it up, 50:1 mix. It started right up and I ran it for about 10 minutes. I then pressed the off switch and turned it off. A few minutes later, I restarted it....no problem. I then went to turn it off and the off switch would not work. I tried it repeatedly and finally had to pull off the plug wire. I will be returning this blower to Lowe's for a refund. That was the first and last Husqvarna I will ever buy. A brand new blower with a bad off switch.....no thanks!
