New saw- blade height stuck

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

Is there a lock that has to be released before it can be moved, and if so is it releasing properly?

Do you have a friend who owns a table saw who can help you?

Yes there is a thumbscrew that locks the wheel. I loosened it as per instructions, even removed it.

I did remove the styrofoam block per setup instructions.
I have done everything except plug it in.

By the way- in case you are wondering- I removed that styrofoam block by tilting the blade, since I could not raise the blade.

It is past time to call Grizzly and tell them to have the saw picked up and send you one that works. Why bang your head against a brick wall on a new unit.

You have two choices ...

Attempt to fix the issue yourself OR return the unit as "defective".
The first step in fixing it yourself is to review the parts manual PDF page 76 and understand it completely. It is apparent to me the elevation mechanism is locked up or seized. Page 59 lists the symptoms which might cause this. Close inspection of the gears, rods and pins may reveal the cause.

Ordinarily, Grizzly is great about returns, so that would be your last resort. However, replacing parts that break under stress is not the answer, so you must find the cause of the lock up. The choice is yours, of course.

The answer to your question will only be as detailed and specific as the question is detailed and specific. Good questions also include a sketch or a photo that illustrates your issue. (:< D)

There is an old saying (If it don't go don't force it). If something doesn't turn there is a reason so find the reason and fix it. I have called Grizzly several times and most of the time they do great at helping but sometimes you get a person that is new or maybe just don't know so I call back later and talk to another person.

I agree with hawkeye10. Grizzly support has been quite helpful the couple times I have called them. Once was for an older drill press I purchased off of Craigslist. I got good advice from grizzly and they even sent me a speed diagram for the pulleys free of charge.

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.

Grizzly is great about taking returns, but I had to drive 200 miles round trip to drop off a scroll saw that would not run when I got it. That is the only way they would take it back, if I took it in person. Then had to wait while their shop checked to make sure that it didn't work.

I can't see how you sheared a pin holding the blade elevation hand wheel to the shaft. On my Grizzly Z771X (purchased last Sept.) the handwheel is held to the shaft by the knob that locks the blade height. Removing that knob allows the handwheel to be pulled off the elevation shaft. Are they making them different now?

While the knob was removed I had to push the wheel in with enough force to engage the pin and hold it in place while attempting to turn the wheel.

You don't have to push the handwheel in at all. In fact the outer knob locks the wheel. What you were doing was holding the wheel locked so it could not turn.
