The RF-100 must be level for proper operation. after discovering that
my loading bench was not level, (and floor not level )
I made a modification to the RL-100 by removing the rubber feet
and replacing them with threaded feet, stop nuts washers and wing nuts
and adding a bullseye level to the base on the L/H side.
I am now able to verify level and adjust as needed
