Sometimes old style is better, bet it won't work harden your stock . No worries about tension on the blade set it once and forget it. If you set up a little lube pot or spray your blades will dern near last forever. Baring trying to cut files or hard chrome . I'm a fellow power hacksaw owner an old miller Knuth , mine cuts on the push stroke not the pull . Make sure yours is set up the right way. It may have the blade on backwards , I've seen it happen many times. Not trying to say it is but try looking up the manual it will tell . Good luck with her you made a great purchase there.
