<h2 style="text-align:justify">KaVo INTRA EVA Head L61 G / L61 R Care Guide: Protecting the Stroke and the Snap-In Lock</h2>

&nbsp;

EVA heads don&#39;t spin, so their care routine focuses on two parts: a damped stroke mechanism and, on the L61 R, a 36-position locking system. Both depend on being clean and properly cared for.

Here is a routine based on what KaVo officially lists for these heads.

&nbsp;

At a glance (KaVo specifications): Thermo-disinfectable and sterilizable up to 135&deg;C (275&deg;F) &middot; file ejector tool 0410.0634 listed by KaVo US &middot; 2-year warranty.

&nbsp;

<h2 style="text-align:justify">&nbsp;The 30-Second Brief</h2>

&nbsp;

<ul>
	<li>
	Remove files and strips with the ejector tool KaVo lists (0410.0634).
	</li>
	<li>
	Separate the head from the shank, clean inside and out, then apply KaVo care.
	</li>
	<li>
	Sterilize at no more than 135&deg;C.
	</li>
</ul>

&nbsp;

<h2 style="text-align:justify">&nbsp;By the Numbers</h2>

&nbsp;

<ul>
	<li>
	0.8 mm stroke to keep running smoothly
	</li>
	<li>
	36 snap-in positions to keep clean (L61 R)
	</li>
	<li>
	135&deg;C maximum sterilization temperature
	</li>
	<li>
	2-year KaVo warranty
	</li>
</ul>

&nbsp;

<h2 style="text-align:justify">&nbsp;Start With the Right Removal Tool</h2>

&nbsp;

KaVo&#39;s US page lists a file ejector tool (0410.0634) with both EVA heads. Using it to remove files and strips protects the head from improvised tools
