|1- ARM: open the wrench to adjust it to the filter.|
|2- SELECT : the screw or unscrew position|
|3- CLIP : the wrench locks automatically in contact with the filter.|
|4- UNTIGHTEN : unscrew the filter with a ratchet.|
Now just use a ratchet on an extension to untighten the filter.
A patented system increases jaw tightening with the increased unscrewing force on the ratchet.
For the most complicated accesses, a tightening position is also available.
This tool was designed and built by FACOM teams in France.
It is also manufactured in France in the Arbois site (Jura).
