Seemed to me they are very similar.

Hi,
Are you really sure your tools (drill, circular saw and router) support 54V?
If you buy one of these mitre saws, you'll have 2x6AH 54V batteries.
Are you really sure that batteries will be compatible with your current tools?
No worries mate.
You probably loosened the throat (insert) plate locking screw too much and the bracket fell down. Keep in mind, it only takes a quarter turn to loosen and tighten.
Happy new year...
Manual KS 210 HM Plus
Seems that the stock number of the the part you're looking for is 101 068 9928.
And the manual has detailed diagrams of the parts. Maybe you can fix it with help of diagrams. (Sounds like a spring issue)
Pages 18 - 29 are in English.
Hope this helps.
