The 1590, like several Bosch jigsaws, has a selector switch to choose the type of cutting action. You have to choose the appropriate cutting action, either straight or oscillating, to accommodate the material you cut and the blade you cut with. For instance, if using a very slender blade for clean curved cuts in wood, a slight oscillating motion ( setting II or III) reduces friction on the blade.
If you choose the straight cutting action you get maximum accuracy, but drastically increase the friction because the blade is held firmly to the roller bearing. A slender blade can handle that for brief periods, (say... less than thirty seconds) in soft, thin wood with a straight cut. In hard woods or engineered wood products ( plywood, MDF etc.) the thin blade will heat up and bend.
You can reduce friction by choosing an oscillating cutting motion, or you can use a larger, sturdier blade. The "Aggressor" blades do not cut as smoothly as the "clean" blades, but they cut faster and are stronger. To cut thick wood ( 4x4 ) or a long cut in engineered material, that is the blade I use. Select number III or number II for 'type-of-cut' and use a bigger blade. See if that stops the "bucking."
