Errors in manual? - Crack chassis assembly done but with one spare #6 lockwasher

[cddc]

Just finished assembled the Crack chassis. But found I was left with one #6 lockwasher unused.

I double checked the manual, and really couldn't find where it should go.

There are two #6 lockwashers in total. One of them goes to the front hole for the nine-pin socket. But where should the 2nd #6 lockwasher go?

Is it possible that there's an error in the Crack manual, or the left-over #6 lockwasher will be used later in the speedball upgrade (which has not been done yet)?

Really appreciate it if anyone could help.

2 are used. Which crack version do you have?

Thank you very much for your kind answer.

I can only see one of them is used in the front hole for the 9-pin socket on Page 13. Really don't know where the 2nd #6 lockwasher should go.

The front page of my Crack manual says "revised December 17, 2013...copyright 2010" .

The front page of my Speedball manual says "Speedball 1.1 manual...copyright 2015"

My Crack is the 120V only version, which I bought at the beginning of this year. Just started to assemble it this weekend.

So it's not the new universal 120/240V version.

It should go between the 5-lug and the nut on the 9-pin socket.

Great, thank you very much.
