ok ive had 2 days with it and its not gone well. very unhappy so far.first i cut a worktop and it wasnt effortless at all. i had to put a fair bit of push into it, and there was burn marks over all over the cut. at first i thought it was because of no riving knife or that doing a full 40mm in one go was a bit too much for it. not happy as my 18v dewalt will cut easier. then i was doing 18mm chipboard and it was the same,burning and stiff. i havent overtightened it on the rail tho cos it glides with ease turned off. feeling a bit dissheartened i thought i'd just phone for a new blade when i get home from work. but it gets worse, i had to trim the full lenghth of a door(cheap 6 panel hollow) of about 8mm. by half way up the door it was so stiff to push i had to stop. took a look at the cut and it cut off to the right by about 3-4mm which was obviously bending the blade making it so hard to push. that was final straw and i'd give up with it. called d&m and they said it never had that and it would have to go back to makita. but i need it for next wk so after much haggling their posting me a new one tomo after the old is picked up. just really hoping that it was a fault and not the fact its carp. so dissapointed. wish i'd bought the dewalt now. STEVE THE FITTER as you have one i was hoping for some reassurance that i just had a dudd. would you expect it to trim a door in 1 pass and a worktop?? should i would expect. also i found a reveiw somewhere on the net a while back that someone had a prob with theirs that the blade was not parralel with the saw base which sounds like what was causing my problems.
