9.2 PRECAUTIONS AFTER REPAIRS.

After making repairs, take care to organize the wiring so
that there is secure insulation between the primary and
secondary sides of the machine.
Do not allow the wires or the gas pipes to come into con-
tact with moving parts or those that heat up during op-
eration.
Reassemble all clamps as they were on the original ma-
chine, to prevent a connection from occurring between
the primary and secondary circuits should a wire acci-
dentally break or be disconnected.
Also mount the screws with geared washers as on the
original machine.
