Yellow Tubular Steel Parts

[chodges]

I am nearing the end of assembling my machine, but I don't see anything in the assembly manual that mentions where the two 4' long x 1-1/4" diameter yellow tubes are mounted or what they are for.

Help?

Thanks!

New addition since publicaton of the manual, not in my manual either.
They are safety rails that bridge the gantry. They act as "Hey, here comes the machine reminders!" for those of us that like to lean on the rails and watch the machine run. Good addition!

Are those yellow tubes only for Alphas and not included with Standards?

Yes. Only Alphas.
