Blade slips off
- This message contains a plea for help!
I've uploaded a photo
of my Central Machinery S-37151 saw, which I believe fits in with all
the others in this group. I've tried to get help from some of the
groups that may overlapSherline, Home_Machinist, Little_Machines. I
got a number of replies, but none of them seem to help.
The problem is that the blade consistently comes off the top (when
the arm is upright) wheel.
The manual (page 16) gives a procedure for adjusting the blade
tracking. In my photo, the bolts marked D and E correspond to the
callouts on page 16.
For openers, I was leery of the instructions to make these
adjustments with the machine running and the wheel cover open. Sorry,
we didn't do it that wayclosed the door each time before turning it
on; and it's a good thing, because the blade would have been spinning
across the garage. Consequently, we were never able to follow the
adjustment procedure, which directs us to make the adjustments while
the machine is running.
We (my son and II needed moral support) found that the two wheels
were not in the same plane. We checked this with a long straightedge.
By moving adjustment bold D in and out, we were able to even them up
in the same plane. But it soon became evident that the top wheel had
both a pitch and a yaw problem, which we assumed that we could
correct the pitch by adjusting bolt E, which we were able to do to
some degree. But the wheel is still yawing enough to throw the blade
off in just a revolution or two, and I can find no way to adjust the
What are we doing wrong? How do we go about fixing this thing?
- Welcome, you're in the right place.
If the saw is new or very recently purchased, I'd return it. If you
can't, then I'd try to take the upper wheel off and see if something
was worn. HarborFreight sells replacement parts for the saw.
Hopefully one of the more experienced saw users will have more
