3.
Test for continuity across the terminals of the switch. The switch should be CLOSED with
the Motor Carriage in neutral position.
4. If the switch measures OPEN while the Motor Carriage is in neutral position, adjust the
magnet closer to the switch and repeat step 3.
5.
Push the carriage forward until it makes contact against the Face Plate. The switch
should now measure as OPEN. (A few kilo ohms of resistance are normal when the
switch is OPEN.)
6.
If the switch does not OPEN loosen the mounting nuts and adjust the magnet as far as
possible from the reed switch, and repeat step 5.
7.
If the switch continuously measures CLOSED regardless of how far away the magnet is,
replace the switch assembly.
8. If the switch continuously measures OPEN regardless of how close the magnet is, re-
place the switch assembly.
9.
If the switch needs to be replaced the laminate strip on the front of the machine may
need to be removed to access the switch retaining screws. Pry the laminate free from
the case with a sharpened putty knife. Contact Castle for a replacement laminate strip.
