mine did this little over 2 yrs. ago. nothing i tried worked. i finally took it to a repair center. they replaced part #8-rocker assembly vertical-$56.98. it was
bent. total cost $116.00. they said it was a common problem with dewalt. they
also said not to pick up saw by upper arm as that could cause the rocker asy.
to bend. i am still pleased with my saw. termite
