Broken Dolmar power cutter saws part 1: Diagnostics 

I bought 3 Dolmar power cutter saws (2x PC-6112 and a PC-6114). All are broken. Can I fix them and sell them, making a little profit? In this video I try to find out what the problems are. The Makita EK6100 and EK6101 are the same saws as these ones, only with an other color.
