switch disabled by a padlock.
The switch can be disabled and locked by insert-
ing a padlock through the ON/START button, as
shown. Locking the switch in this manner can
prevent unauthorized operation of the machine,
which is especially important if the machine is not
stored inside an access-restricted building.
IMPORTANT: Locking the switch with a padlock
only restricts its function. It is not a substitute
for disconnecting power from the machine when
adjusting or servicing.

installation
When installing the h8243 switch, use the wiring
diagram in
figure 2
to ensure proper wire con-
nections.
this switch is intended to be connected to
stranded wire with insulated crimp-type ring
wire terminals.
all crimps must be "pull-checked" to ensure
that wires are securely crimped and will
not fall out with moderate tension or when
exposed to normal machine vibration.
*the machine MUst be connected to a verified
ground. in the event of certain malfunctions or
breakdowns, grounding reduces the risk of elec-
tric shock by providing a path of least resistance
for electric current.
