Thread: cant wind blade down on cabinet saw, advice or fix pretty please

The photo's are not very clear but the first thing I would try is blow all the dust off and add some "lubrication"

I have a very similar table saw, and every now and then I have to use compressed air particularly around the rear vertical slide and the bottom of the adjusting screw towards the front where there is a thrust bearing. Once all dust has been blown out, I use a dry lube such as PTFE spray which usually makes the mechanism as good as new. I have had to do this process every few months, but only access the innards from the top after removing the blade and from the side access door.

Alan...

cheers, its been cleaned numerous times with compressor to get every spec out (ignore any in pics)
and ive tried lubrication with grease, oil, and wd40 (trying and cleaning inbetween each one)

no downwards movement so far

There is probably a build up of material in the mechanism some whear you may need to disasemble and give it a good clean

i was hoping the term "disassemble" wasnt going to be part of the solution.
i have a bucket of bolts left over from things ive disassembled and put back together
thanks china. looks like my weekend is full now

fixed it. dont know how exactley
went through the same cleaning lubrication ritual i have tried a dozen times
this particular time i held my tongue at a slightly different angle, and made sure i had a nice scotch for assistant.
so thanks for the help, all good

I've this exact saw. It's well behaved, but the mechanism does need periodic cleaning.

With the DE on, I blast compressed air around the cabinet until its empty, then paying extra attention to all the gaps, threads etc. This is just done with a air trigger attachment with a 30cm nose. It's gets right in.

Next is a lube of the threaded raiser rod, the upper and lower thrust bearing and the trapezeiod guide system. This can bind hard and I don't like the design (but it's stable and functional). When the saw was first acquired the little grub screws which keep it goldilocks-tight needed adjustment, but not since.

If any crud clags the thrust surfaces of that trapezoid it will lock right up hard.

I use bike chain dry Teflon lube.
