Changing
Motor
Voltage
_11_DANGER:
To avoid electric shock unplug the saw before changing
motor voltage.
Under
normal
home workshop
usage, and if
full voltage
is supplied
to the motor,
your saw
will operate
efficiently
on 120V, as connected
at the factory.
However,
if any of the follow-
ing conditions
exist, it will be advisable
for
you to have a qualified
electrician
reconnect
the motor for 240V operation:
Dual Voltage Switch
• I [eavy duty operations.
• Either
an undersized
or an overloaded
branch
circuit serving
the saw motor.
• Low voltage
supplied
by the power
source, which the power company
can-
not correct.
The procedures
for changing
the motor volt-
age (factory set for 120V) are described
below. These
instructions
should be followed
by a qualified
electrician
only.

3. Replace
the 120V power
cord plug with a
240V, 15 AMP, 3-blade
plug. (Figure
188)
Note: Whenever
changing
the switch position
from 120V to 240V or vice versa, make cer-
tain that all necessary
steps (including
proper
fusing of the branch
circuit)
are completed.
Connection
