PRECAUTIONS AFTER REPAIRS.

After making repairs, take care to organize the wiring so that
there is secure insulation between the primary and secon-
dary sides of the machine. Do not allow the wires to come
into contact with moving parts or those that heat up during
operation. Reassemble all clamps as they were on the origi-
nal machine, to prevent a connection from occurring
between the primary and secondary circuits should a wire
accidentally break or be disconnected.
Also mount the screws with geared washers as on the ori-
ginal machine.
DISPLAY POSSIBLE SOLUTION
TRG Shut off the Power Source, remove the start
command and restart the Power Source
TH0 Don't shutting off the Power Source, to keep the fan
running and thus allow rapid cooling. Normal opera
tion is restored automatically as soon as the tempe
rature returns within the allowed limits. If the problem
persists, call CEBORA Service Department
