<h2 style="text-align:justify">Caring for an NSK SGA-ES 
&nbsp;</h2>

The 20&deg; angle of the NSK SGA-ES is part of its clinical design, but it doesn&#39;t change the fundamentals of good handpiece care.&nbsp;The SGA-ES is a 1:1 direct-drive, non-optic surgical handpiece designed for &Oslash;2.35 mm surgical burs and equipped with a twist chuck. Consistent maintenance helps support smooth rotation, reliable bur retention, and predictable performance.&nbsp;A simple maintenance routine can also help identify changes before they become a larger mechanical problem.

<h2 style="text-align:justify">A Better Maintenance Habit 
&nbsp;</h2>

Instead of waiting for a problem, make a few simple checks part of your regular workflow. 
&nbsp;

<h3 style="text-align:justify">Before Use 
&nbsp;</h3>

Inspect the: 
&nbsp;

<ul>
	<li style="text-align:justify">
	Surgical bur
	</li>
	<li style="text-align:justify">
	Twist chuck
	</li>
	<li style="text-align:justify">
	Angled head
	</li>
	<li style="text-align:justify">
	External condition
	</li>
	<li style="text-align:justify">
	Rotation 
	&nbsp;
	</li>
</ul>

Make sure the bur is compatible, straight, undamaged, and securely retained. 
&nbsp;

Pay attention to any new vibration, unusual sound, resistance, or change in rotation. 
&nbsp;

<h3 style="text-align:justify">After Use 
&nbsp;</h3>

Clean the handpiece according to the current NSK instructions before proceeding with lubrication and reprocessing.&nbsp;Remove visible contamination carefully and pay particular attention to the working end and chuck area.&nbsp;Do not use unsuitable instruments or cleaning methods that could damage the handpiece. 
&nbsp;

<h2 style="text-align:justify">Keep the Twist Chuck in Good Condition 
&nbsp;</h2>

The twist chuck is responsible for securing the surgical bur and should operate smoothly. 
&nbsp;

During routine care, check that: 
&nbsp;

<ul>
	<li style="text-align:justify">
	The chuck turns normally
	</li>
	<li style="text-align:justify">
	The bur inserts correctly
	</li>
	<li style="text-align:justify">
	The bur is securely retained
	</li>
	<li style="text-align:justify">
	There is no unusual resistance
	</li>
	<li style="text-align:justify">
	There is no visible contamination or damage 
	&nbsp;
	</li>
</ul>

If the chuck suddenly becomes difficult to operate or the bur no longer feels secure, the handpiece should be inspected before further clinical use. 
&nbsp;

<h2 style="text-align:justify">Lubrication Matters 
&nbsp;</h2>

Use the approved lubricant and NSK-recommended maintenance method for the SGA-ES.&nbsp;Proper lubrication helps support the bearings and internal rotating components. Always follow the manufacturer&#39;s procedure rather than assuming that more lubricant provides better protection.&nbsp;Cleaning should be completed appropriately before lubrication. Lubrication should be part of a consistent routine, not something performed only after unusual noise or rough rotation appears. 
&nbsp;

<h2 style="text-align:justify">Reprocess Correctly 
&nbsp;</h2>

Follow the manufacturer&#39;s current instructions for cleaning, disinfection, lubrication, and sterilization.&nbsp;NSK documentation states that the relevant micro-surgery handpieces can be washed in a thermodisinfector and autoclaved up to 135&deg;C.&nbsp;Always verify the current NSK instructions for the specific model and follow your facility&#39;s validated reprocessing workflow.&nbsp;Correct reprocessing helps protect both the handpiece and its internal components while maintaining appropriate clinical hygiene. 
&nbsp;

<h2 style="text-align:justify">Pay Attention to the Angled Working End 
&nbsp;</h2>

Because the SGA-ES has a 20&deg; angled configuration, the head and working end deserve particular attention during routine inspection. 
&nbsp;

Check for: 
&nbsp;

<ul>
	<li style="text-align:justify">
	Residual contamination
	</li>
	<li style="text-align:justify">
	Visible damage
	</li>
	<li style="text-align:justify">
	Signs of impact
	</li>
	<li style="text-align:justify">
	Abnormal movement
	</li>
	<li style="text-align:justify">
	Changes in the working-end condition 
	&nbsp;
	</li>
</ul>

Avoid forcing the handpiece into a position during treatment that creates unnecessary mechanical stress. 
&nbsp;

<h2 style="text-align:justify">Don&#39;t Ignore Early Warning Signs 
&nbsp;</h2>

Maintenance is also an opportunity to monitor the handpiece&#39;s condition. 
&nbsp;

Watch for: 
&nbsp;

<ul>
	<li style="text-align:justify">
	New or increasing noise
	</li>
	<li style="text-align:justify">
	Rough rotation
	</li>
	<li style="text-align:justify">
	Vibration
	</li>
	<li style="text-align:justify">
	Chuck resistance
	</li>
	<li style="text-align:justify">
	Bur movement
	</li>
	<li style="text-align:justify">
	Excessive heat
	</li>
	<li style="text-align:justify">
	Reduced performance 
	&nbsp;
	</li>
</ul>

These symptoms should not simply be treated as normal wear. If they persist after routine maintenance, professional inspection may be necessary. 
&nbsp;

<h2 style="text-align:justify">The &quot;Before You Store It&quot; Check 
&nbsp;</h2>

Before storage: 
&nbsp;

<ul>
	<li style="text-align:justify">
	Remove contamination
	</li>
	<li style="text-align:justify">
	Complete the approved maintenance procedure
	</li>
	<li style="text-align:justify">
	Check the twist chuck
	</li>
	<li style="text-align:justify">
	Inspect the angled head
	</li>
	<li style="text-align:justify">
	Look for visible damage
	</li>
	<li style="text-align:justify">
	Confirm normal operating condition
	</li>
	<li style="text-align:justify">
	Store the handpiece in a clean, protected location 
	&nbsp;
	</li>
</ul>

Avoid storing the handpiece where it can be dropped, crushed, or exposed to unnecessary contamination.

<h2 style="text-align:justify">When Maintenance Is No Longer Enough 
&nbsp;</h2>

Routine maintenance can help prevent avoidable problems, but it cannot correct every mechanical fault.&nbsp;If the SGA-ES continues to show vibration, unusual noise, excessive heat, rough rotation, or unreliable bur retention after appropriate maintenance, stop using it and arrange professional inspection.&nbsp;Early professional service can help determine whether the problem involves the chuck, bearings, internal drive, or another mechanical component.
