The Rupes® 9C2X0.8VUS9 power cord is the same model installed on all Rupes 110-volt two-prong machines since about 2013. Note that the factory increased the cord length from about 4 meters to 9 meters; 2012 machines were equipped with a much thicker and stiffer cord. Specifications: 18 gauge, 2-wire, 2-prong.
Replacing it is relatively simple using very simple tools. Tools typically needed to remove and replace the cord include a Phillips screwdriver, wire cutters or scissors, wire strippers, terminal crimpers, and heat shrink tubing (to cover the terminals if necessary).
This set is compatible with the following machines:
LHR15ES | LHR15ll | LHR15lll
LHR21ES | LHR21ll | LHR21lll
LHR12e | LHR75e | LH19E | LK900E
