<h2 style="text-align:justify">W&amp;H Synea Fusion WG-67 LT Maintenance: Protect the Reciprocating Mechanism Before Problems Start 
&nbsp;</h2>

A W&amp;H Synea Fusion WG-67 LT has a job that depends on controlled movement. It is not simply spinning a conventional bur. The WG-67 LT is a 2:1 Profin&reg; reciprocating contra-angle with a 1.1 mm stroke, single spray and compact glass-rod illumination, designed for Dentatus tips. W&amp;H lists applications including removal of excess materials, pre-polishing, fine polishing and interdental/subgingival polishing. That makes maintenance particularly important around the tip-retention system, reciprocating mechanism, spray pathway and optical components. A good routine is less about doing more and more about checking the right things at the right time. 
&nbsp;

<h2 style="text-align:justify">Build Maintenance Around Four Checkpoints 
&nbsp;</h2>

Instead of treating maintenance as one long task at the end of the day, use four checkpoints: 
&nbsp;

TIP &rarr; CLEAN &rarr; MAINTAIN &rarr; CHECK 
&nbsp;

This simple approach makes it easier for staff to notice a change before the handpiece develops a major problem. 
&nbsp;

<h2 style="text-align:justify">1. Start With the Tip 
&nbsp;</h2>

The tip is where the clinical work happens, so it should be the first part inspected. Before use, confirm that the appropriate Dentatus tip is installed correctly and securely. Do not continue using a damaged or questionable tip simply because the handpiece still operates. If a tip suddenly feels different, test with an appropriate known-good tip before assuming that the handpiece itself has failed. If the problem remains with different tips, it is time to investigate the handpiece rather than repeatedly changing consumables. 
&nbsp;

For general guidance on protecting dental handpieces from avoidable wear, see these <a href="https://repair.dental/repairguru/handpieces/simple-dos-and-donts-for-handpiece-care">handpiece care do&#39;s and don&#39;ts</a>. 
&nbsp;

<h2 style="text-align:justify">2. Keep the Working Area Clean 
&nbsp;</h2>

The head and tip area are exposed to material during polishing and finishing. 
&nbsp;

Buildup around moving or retaining components can eventually affect how the mechanism behaves. 
&nbsp;

After use: 
&nbsp;

<ul>
	<li>
	Remove the tip correctly.
	</li>
	<li>
	Follow the manufacturer&#39;s cleaning procedure.
	</li>
	<li>
	Remove contamination without forcing debris deeper into the instrument.
	</li>
	<li>
	Inspect the tip-retention area.
	</li>
	<li>
	Follow W&amp;H&#39;s approved reprocessing process. 
	&nbsp;
	</li>
</ul>

Avoid treating every handpiece with the same cleaning method. 
&nbsp;

The current manufacturer&#39;s instructions should take priority over a generic clinic routine. 
&nbsp;

<h2 style="text-align:justify">3. Lubrication Is a Procedure, Not a Guess 
&nbsp;</h2>

A common maintenance mistake is assuming that more lubricant automatically means better protection. 
&nbsp;

It doesn&#39;t. 
&nbsp;

The objective is to use the correct lubricant, amount and application procedure for the instrument. 
&nbsp;

RepairGuru&#39;s <a href="https://repair.dental/repairguru/handpieces/handpiece-lubrication-systems-best-practices-maintenance-protocols">handpiece lubrication and maintenance guide</a> provides broader guidance on lubrication systems and maintenance practices.

 
If the WG-67 LT remains noisy, rough or unusually warm after proper maintenance, don&#39;t simply add more lubricant and keep using it. 
&nbsp;

That is the point where maintenance may have become a repair issue. 
&nbsp;

<h2 style="text-align:justify">4. Don&#39;t Forget the Single Spray 
&nbsp;</h2>

The WG-67 LT uses a single-spray system. During routine care, compare the spray with its normal pattern. A change in spray should trigger a simple sequence: 
&nbsp;

Observe &rarr; clean according to instructions &rarr; check water delivery &rarr; retest. 
&nbsp;

If the spray remains weak or inconsistent, don&#39;t compensate by increasing pressure during clinical use. 
&nbsp;

If you are unsure whether the issue is related to the handpiece or the dental unit, contact Repair.Dental through <a href="https://repair.dental/contact">chat or the available contact options</a> before continuing with inadequate cooling. 
&nbsp;

<h2 style="text-align:justify">5. Protect the Glass Rod 
&nbsp;</h2>

The LT version includes a compact glass rod, so illumination should be included in the daily check. 
&nbsp;

Before treatment, look for: 
&nbsp;

<ul>
	<li>
	Normal illumination
	</li>
	<li>
	Clean optical surfaces
	</li>
	<li>
	Secure connection
	</li>
	<li>
	No sudden reduction in light output 
	&nbsp;
	</li>
</ul>

A light problem should not automatically be treated as a mechanical failure. Check the obvious external causes first and follow W&amp;H&#39;s cleaning instructions. If illumination remains weak, mention it when submitting the handpiece for service. 
&nbsp;

<h2 style="text-align:justify"> 
Your 60-Second Pre-Use Check 
&nbsp;</h2>

A busy practice does not need a complicated checklist. 
&nbsp;

Before placing the WG-67 LT into clinical use, ask: 
&nbsp;

Tip: Is it secure? 
&nbsp;

Movement: Does reciprocation feel normal? 
&nbsp;

Sound: Is the operating sound familiar?

&nbsp;

Spray: Is cooling normal? 
&nbsp;

Light: Is illumination working normally? 
&nbsp;

Temperature: Does anything feel unusually warm? 
&nbsp;

If one answer is &ldquo;no,&rdquo; don&#39;t automatically send the handpiece straight back into service. 
&nbsp;

<h2 style="text-align:justify">When Maintenance Cannot Fix the Problem 
&nbsp;</h2>

There is a clear difference between maintenance and repair. 
&nbsp;

Maintenance can help prevent avoidable wear. 
&nbsp;

It cannot restore a damaged internal component. 
&nbsp;

If the WG-67 LT develops persistent: 
&nbsp;

<ul>
	<li>
	vibration
	</li>
	<li>
	abnormal noise
	</li>
	<li>
	tip-retention problems
	</li>
	<li>
	excessive heat
	</li>
	<li>
	poor reciprocating performance
	</li>
	<li>
	recurring spray problems
	</li>
	<li>
	illumination failure 
	&nbsp;
	</li>
</ul>

move from maintenance to professional evaluation. 
&nbsp;

<a href="https://repair.dental/services/handpiece-repair/w-and-h-dental-handpiece-repair">W&amp;H handpiece repair</a> is the appropriate next step when a mechanical problem persists. 
&nbsp;

<h2 style="text-align:justify">Protect the Handpiece&mdash;and Know When to Ask for Help 
&nbsp;</h2>

The best maintenance routine is not the most complicated one. 
&nbsp;

It is the one your team performs consistently. 
&nbsp;

Use correctly &rarr; clean correctly &rarr; maintain correctly &rarr; inspect &rarr; act when something changes. 
&nbsp;

If your WG-67 LT is already behaving differently, don&#39;t keep trying increasingly aggressive maintenance methods. 
&nbsp;

Instead, <a href="https://repair.dental/services/handpiece-repair/w-and-h-dental-handpiece-repair">submit a repair request through Repair.Dental</a> or contact the team through chat/WhatsApp and explain the symptom. 
&nbsp;

Catching a developing problem early is usually better than discovering it when the handpiece is needed for the next patient.
