Unplug machine from power source. Remove key drum assembly. To the right
of the measuring wheel is the safety switch assembly EA570BX. At the base of this assembly
is the safety switch spring E565B. This is where the adjustment will be made.
With the screw driver, turn the reset screw all the way up. Now with the needle nose
pliers bend the flat spring at the right hand side at the curved portion to shift the
reset screw and allow it to move freely in the slot. Check adjustment by pressing down the
switch pin from the top. Revolve measuring wheel manually to make sure the switch shuts
oft when the bumper suction cup comes within 1/4" of the bumper plate. If it doesn't,
readjust the screw and spring until it resets at the proper point.
With screw driver and 5/16" open end wrench, tighten to secure the screw in position.
