Topic tags/keywords: grizzly g0771z blade height adjustment

I purchased a G0771Z 10” Hybrid Table Saw from Grizzly which was delivered three weeks ago.
After assembly, I attempted to adjust the blade height and found the adjustment wheel would not turn.

I ended up shearing the roll pin that engages the wheel to the adjustment shaft.
Grizzly sent a new pin which I installed, but then I broke the adjustment wheel attempting to turn it.
Grizzly is sending a new wheel, but they have not been any help in determining why the height adjustment mechanism is locked up.
Does anyone have any suggestion what I can do to free up the height adjustment mechanism?

Thanks,

Bill Morrow

On my old Bridgewood table saw the height adjustment is done with a worm gear on the end of the adjustment shaft. The worm gear meshes with a semicircular gear that raises and lowers the saw blade. There is a roll pin thru the end of the worm gear. Sometimes this pin shifts slightly thru vibration and jambs against the semicircular gear. That prevents the height adjustment shaft/wheel from turning.

This is all conjecture. Just based on my saw.

Could the knob that holds the wheel on be too tight? I have the grizzly g0833 and if you tighten the knobs too tight, the adjustment wheels won’t turn without force. I have not forced them and back off the knob when turning them.

seuss- I took the locking knob off entirely and the wheel still will not move.

lew- It’s hard to see the parts inside the cabinet, but I will look for the problem you mentioned. Thanks.

Did you remove the styrofoam shipping block that holds the motor in place ?

I sprayed the shaft liberally with penetrating oil. After letting it sit a while it broke loose and seems to OK now. Thanks for the help.
