HK 85 issue.
« on: April 12, 2017, 04:59 PM »
The depth  adjustment  lever has stopped working  on my HK 85 EB. It did seem  a  little stiff  when I first used the machine  from new  but worked OK. I'm not sure how it works  but I think  pressing the adjustment  lever causes   the  inner  part to flex thus  separating it from the serrated edge, thus allowing   the  adjustment to take place.
I'd just thought  it would loosen up with more frequent use.

I removed  the  side  plate  that houses  the  large  plunge spring.
I could see  the   serrated    surface  that  the adjuster  travels on  but without further disassembly  I have no access  to  see what the  adjustment  lever   is actually doing  or how  the mechanism  works.
Any help appreciated.

Thanks.
The mechanism  is working  OK now. Can see  how it operates  when  extended  as the lever becomes visible.
