<h2 style="text-align:justify">Use This Checklist Straight Away</h2>

&nbsp;

This checklist is built for the COXO CX207-C H14 high-speed handpiece. Work through the daily items every day, the weekly items once a week, and the monthly items once a month. If any item fails, the &quot;stop&quot; section at the end tells you what to do next.

The checks are general good practice organized around the H14&#39;s published features. They sit alongside the cleaning, lubrication, and sterilization steps in your COXO user manual, not in place of them.

&nbsp;

<h2 style="text-align:justify">Daily Checks</h2>

&nbsp;

<ul>
	<li>
	☐ Run the handpiece briefly before the first patient and listen for a smooth, steady sound.
	</li>
	<li>
	☐ Check the single water spray reaches the bur evenly.
	</li>
	<li>
	☐ Confirm the handpiece seats firmly on its Midwest four-hole or two-hole connector.
	</li>
	<li>
	☐ After each patient: clean, lubricate as your manual describes, and sterilize. COXO lists the H14 as heat sterilizable, and its FAQ generally recommends autoclaving.
	</li>
</ul>

&nbsp;

<h2 style="text-align:justify">Weekly Checks</h2>

&nbsp;

<ul>
	<li>
	☐ Bur grip test: seat a new bur fully in the push-button chuck and pull firmly.
	</li>
	<li>
	☐ Connector seals: look for flattened or cracked O-rings.
	</li>
	<li>
	☐ Body check: inspect the aluminium alloy body for dents or damage.
	</li>
	<li>
	☐ Spray comparison: compare the spray with another handpiece on the same chair.
	</li>
</ul>

&nbsp;

If the grip test fails, stop using the handpiece and <a href="https://repair.dental/print-shipping-label/handpiece-repair">request a handpiece shipping label</a>.

&nbsp;

<h2 style="text-align:justify">Monthly Checks</h2>

&nbsp;

<ul>
	<li>
	☐ Sound review: compare the running sound with how it sounded when new or last serviced. COXO describes its ceramic bearings as balance-tested for quiet running, so a new noise is meaningful.
	</li>
	<li>
	☐ Version check: confirm whether each H14 is an SP (standard head) or TP (torque head), and record it.
	</li>
	<li>
	☐ Air supply: check the compressor drain and dryer, since damp air harms bearings.
	</li>
	<li>
	☐ Sterilizer: confirm your sterilizer&#39;s routine checks are up to date.
	</li>
</ul>

&nbsp;

<h2 style="text-align:justify">What Each Check Protects</h2>

&nbsp;

A checklist is easier to follow when the team knows why each item is there.

&nbsp;

<ul>
	<li>
	Sound checks catch early ceramic bearing wear, before it turns into roughness or heat.
	</li>
	<li>
	Spray checks protect cooling at the bur. With a single water spray, even a partial blockage matters.
	</li>
	<li>
	Grip tests protect patient safety by catching chuck wear before a bur slips during treatment.
	</li>
	<li>
	Seal and connector checks prevent air loss and leaks, which affect power and hygiene.
	</li>
	<li>
	Body inspections catch impact damage that can affect how the head and turbine sit.
	</li>
	<li>
	Air supply checks protect the bearings from damp or oily compressed air.
	</li>
</ul>

&nbsp;

<h2 style="text-align:justify">Recording Your Results</h2>

&nbsp;

A tick box only helps if someone looks back at it. Keep a simple sheet for each H14 with the date, who did the check and a short note for anything unusual. After a few weeks, patterns become obvious: a spray that weakens a little each week, or a sound that slowly changes.

&nbsp;

When you contact a repair provider, that record is valuable. It shows when a symptom started, what has already been ruled out and how quickly things have changed.

&nbsp;

<h2 style="text-align:justify">Using the Checklist With Several H14s</h2>

&nbsp;

Many practices own more than one H14, sometimes a mix of standard head (SP) and torque head (TP) versions on different connectors. Label each handpiece with its head type and connector, rotate them through the week so wear is shared, and run the weekly and monthly checks on every unit, not just the one used most.

&nbsp;

If one handpiece repeatedly fails the same check, take it out of rotation and arrange an inspection while the others keep working.

&nbsp;

<h2 style="text-align:justify">A Note on the Anti-Retraction System</h2>

&nbsp;

COXO lists an anti-retraction system on the H14, designed to reduce the chance of fluids being drawn back into the head. You cannot test this directly at the chair, but you can support it by keeping the handpiece clean and reprocessing it correctly after every patient. Any visible residue inside the head after cleaning is a reason to book an inspection.

&nbsp;

Stop and Get It Checked If...

&nbsp;

<ul>
	<li>
	The bur slips or will not release.
	</li>
	<li>
	The head feels warm.
	</li>
	<li>
	You hear grinding, rattling or a sudden change in sound.
	</li>
	<li>
	Water or air leaks from the head or connector after seals are checked.
	</li>
	<li>
	The body is cracked or dented.
	</li>
</ul>

&nbsp;

Do not try to open the turbine head. Bearing and cartridge work belongs on a repair bench. Repair.Dental&#39;s <a href="https://repair.dental/services/handpiece-repair">high-speed handpiece repair service</a> covers turbines like the H14.

&nbsp;

<h2 style="text-align:justify">Training New Team Members</h2>

&nbsp;

Walk new assistants through the checklist once with a working H14 in hand. Show them what a normal sound and spray look like, how a firm bur feels in the push-button chuck, and where the connector seals sit. Knowing what &quot;normal&quot; looks like is what makes the checks meaningful.

&nbsp;

<h2 style="text-align:justify">Make the Checklist Stick</h2>

&nbsp;

Print this checklist and keep it in the sterilization area. Assign one person to sign off the weekly and monthly items. If keeping track across several handpieces is difficult, Repair.Dental&#39;s <a href="https://repair.dental/services/dental-equipment-monthly-maintenance-plans">monthly maintenance plans</a> can take on the routine checks.
