After
cooling
to
a
safe
operating
temperature,
the
overload protector can be closed manually by pushing
in the red button on the top of the motor. If the red
button will not snap into place immediately, the motor
is still too hot and must be allowed to cool for a while
longer. In some cases this may take 20-30 minutes. (An
audible click will indicate protector is closed.)
3.
As soon as the red button will snap into running
position,
the
saw
may
be
started
and
operated
normally, by pulling out the saw switch to the "ON”
position.
4.
Frequent opening of fuses or circuit breakers may result
if motor is overloaded, or if the motor circuit is fused
differently
from
recommendations.
Overloading
can
occur if you feed to rapidly or if your saw is misaligned
so that the blade heels. Do
n o t
use a fuse of greater
capacity without consulting a qualified electrician.
5.
Although the motor is designed for operation on the
voltage
and
frequency
specified
on
motor
nameplate,
normal loads will be handled safely on voltages not
more than 10% above or below the nameplate voltage.
Heavy
loads,
however,
require
that
voltage
at
motor
terminals equals the voltage specified on nameplate.
6.
Most
motor
troubles
may
be
traced
to
loose
or
incorrect
connections,
overloading,
reduced
input
voltage (such as small size wires in the supply circuit) or
to
an
overly-long
supply
circuit.
Always
check
the
connections, the load and the supply circuit, whenever
the
motor
fails
to
perform
satisfactorily.
Check
wire
sizes and lengths with the table following.
WIRE SIZES
The use of any extension cord will cause some loss of
power.
To
keep
this
to
a
minimum
and
to
prevent
over-heating
and
motor
burn-out,
use the
table
below
to
determine the minimum wire size (A.W.G.) extension cord.
Use
only
3
wire
extension
cords
which
have
3
prong
grounding type plugs and 3-pole receptacles which accept
the tools plug.
NOTE: For circuits of greater length, the wire size must be
increased proportionately in order to deliver ample voltage
to the saw motor.
