Great gift from the boss, he must have a a lot of finishing work coming up ;-). I've had my kapex for about a year,wish I'd got it 10 years ago, absolutely love it!! Enjoy!
When you clamp both sides the blade can (should the workpiece twist from relieved stress) bind, which could (with a good chance) have unwanted impact on the blade, the arbor, the motor, your wrist, other stuff - possibly reducing the lifetime of some or all of these... Also quality of the cut can suffer.
