well, usual wash times, as with any machine would be based on fabric and soil level...
heavy...15 minutes
normal..10 minutes
light...3 to 7 minutes
for delicates, something like a 1 minute wash, 1 minute soak....about 4 to 6 times, and then wring.....
start with the instructions for the detergent, one full dose to get you started.....and then 1/2 that amount for each re-use of the wash water...
also starting with the lightest color and soil levels, then move on to darker/heavier soils...
for rinsing, most used a separate washtub or laundry tub, sort of a manual hands on swishing of the clothing, and then back through the wringer/spinner.....
some will wash several loads in the machine, drain, and refill for rinsing....usually 3 to 5 minutes of agitation, and then wring out one last time....
spin rinsing was available on some Easy machines....
granted you may not find the exact instructions, but there are plenty of wringer videos of operating and hints on using one, and then adapt for your own preference and technique....
