Domino Width Knob Question

[Tim2178]

Hello everyone.  I just got my Domino cutter this week.  It's AMAZING!.  One question/concern.  The width knob does not want to turn.  The way I get it to change to the next step is just to turn the domino on for a split second.(not even enough time for the dust extractor to switch on)  Then  the knob turns freely.  Then after cutting a couple more more times I go to switch it back, and again it doesn't want to move.  So I turn it back on for a split second.

Am I doing something wrong?

Thx all!

Tim,

Refer to the manual. You're only suppose to change the mortise width setting while the machine is running. Otherwise, you run the risk of damaging the gears.

Page 10:

Failure to follow the notes below
may result in damage to the tool.

- Never force the dial to turn.
- Rotate the adjustment dial only when the
motor is running.
- Never rotate the dial during a plunging
operation. This can bend or break the
mortising bit, and can also damage the
machine.

Oh.  I thought I saw in a couple tool reviews people turning the knob while the domino was off.  I NEVER forced it to turn.  Most of the time it turns so easy while off.  Does it hurt the Domino gears if it is turned while off?  Not forcing of course.

Doesn't hurt it unless it doesn't want to turn and you force, but the manual does clearly state to only turn it with the machine running.

Ya I realize now that the manual does say that.  I was sooo eager to use the thing I just went with what I knew from watching any and all reviews for the last 3 years. [big grin]  It sure doesn't seem like it would hurt the Domino at all by doing it that way.  From now on I will do it the way they say.  I sure hope I didn't screw anything up [eek]

Despite knowing better, I confess to always turning my domino off before changing the mortise width, it's a bad habit I know. I don't force the turn and my domino is working fine despite the user.

Thanks Tim!  That makes me feel much better.  It just makes me sick thinking that I might have shortened the life of my Domino.  Again, I never forced it into position.

Well it doesn't necessarily mean I am not messing up my machine, but so far it's working fine.

No, as long as you do not force the dial, it won't do any damage. However, forcing the dial will cause damage. Having the machine running just ensures that the gear train meshes up easily. It isn't just a matter of a couple gears meshing, though. Under the dial is a complex series of gears and a yoke, and they won't always mesh when the tool is not running. This can be seen in a cutaway Domino, but I haven't had my hands on one of them in 5 years, so I can't explain it any better from memory. The only thing that stands out in my memory was that there was some sort of triple-set of gears, and rotating the dial moved these gears into different configurations and relocated the tongue of the yoke.
