A Tornado that&#39;s not delivering its full 30 watts (or 24 on the Tornado S) is noticeable specifically because the whole point of this handpiece is that power. Most performance complaints trace back to one of a small number of causes.

&nbsp;

<h2 style="text-align:justify">Warning Signs to Watch For</h2>

&nbsp;

<ul>
	<li style="text-align:justify">Cutting power that feels reduced compared to the handpiece&#39;s usual performance</li>
	<li style="text-align:justify">Bur not locking securely despite the Accu-Chuck PreciPlus system</li>
	<li style="text-align:justify">Uneven water spray across the four Accu-Spray Quattro Mix ports</li>
	<li style="text-align:justify">Noise level rising above the handpiece&#39;s usual quiet operation</li>
	<li style="text-align:justify">Visible wear or damage at the Sealed Head interface</li>
</ul>

Safe Checks You Can Do Yourself

&nbsp;

<ul>
	<li style="text-align:justify">&nbsp;&nbsp;Confirm air supply pressure matches Bien-Air&#39;s specification before assuming a bearing fault</li>
	<li style="text-align:justify">&nbsp;&nbsp;Test bur retention with a known-good bur before assuming the chuck has failed</li>
	<li style="text-align:justify">&nbsp;&nbsp;Visually inspect all four spray ports for debris</li>
	<li style="text-align:justify">&nbsp;&nbsp;Note whether reduced power happens under all conditions or only under heavy load, which helps narrow the cause</li>
</ul>

When to Send It to a Technician

&nbsp;

<ul>
	<li style="text-align:justify">&nbsp;Power loss that persists after confirming air supply is correct</li>
	<li style="text-align:justify">&nbsp;Any visible wear or damage at the Sealed Head interface</li>
	<li style="text-align:justify">&nbsp;Chuck issues that persist with a known-good bur</li>
	<li style="text-align:justify">&nbsp;&nbsp;Noise that&#39;s noticeably higher than the handpiece&#39;s typical quiet operation&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;</li>

FAQ

&nbsp;

Q. Is reduced power always a bearing problem?

A. Not always; rule out air supply pressure first, since that&#39;s the simpler and more common cause.

&nbsp;

Q. Can a scratched coating affect performance?

A. Not directly, but it&#39;s worth tracking since TotalTact is designed to resist this kind of wear. Unusual scratching may point to handling or cleaning practices worth reviewing.

&nbsp;

Q. Does the Tornado S have the same failure points as the Tornado?

A. Yes, both share the same core SteadyTorque and Sealed Head technology, so the same troubleshooting approach applies to both.
