The best way of using the Scorpion saw is to clamp the material on to a bench.
Then using the saw as a hand saw cut the sheet through by about 3mm this stops the blade bouncing at the start.
then run the saw just like a jigsaw, I tend to angle the saw as if it were an ordinary hand saw, about 45 degrees.
To prevent the blade getting hot and clogging the blade. I gently move the blade back and forward this helps the removal of the cuttings and lets the blade cool as well.
