Resetting The Thermal Overload Protector; Causes Of Overload - Craftsman Professional 315.228510 Owner's Manual

RESETTING THE THERMAL OVERLOAD
PROTECTOR
See Figure 55.
Your table saw is equipped with an overload protector
to shut off the saw when a power circuit limit is
reached and the motor temperature begins to rise.
Otherwise, overheating can occur and cause poor
performance, machine damage or fire. Be prepared to
deal with overload should it occur, first in the immedi-
ate situation and then in locating the cause.
If the motor overheats, the overload protector shuts
down the power. Use the steps listed below to restart.
• Turn the switch off to eliminate any possibility of
the blade restarting when the motor has cooled.
Remove any objects, including the workpiece, from
contact with the blade to prevent binding when you
do restart operation.
_, WARNING: If the overload protector shuts off,
immediately turn the saw switch off and remove
anything contacting the blade to prevent the risk
of injury. When the motor cools off, it could
unexpectedly restart the blade, throwing an
object or cutting your hand if you are touching
the blade.
• Allow time for the motor to cool. You may have to
let the motor cool for as long as it had run before
the protector shut it down.
m While the motor is cooling, refer to the section
below to try to determine the reason for overload.
Correct the problem before resuming operation.
• Press hard on the red button on the end of the
motor (opposite end from the pulley). If the motor
has cooled enough, you will hear a click. If you do
not hear a click, let the motor cool longer.
i When you hear the click, the motor has been reset
and you can continue your project.

CAUSES OF OVERLOAD
Overload and overheating result from a number of
sources. Always check the connections, the load and
the supply circuit if motor performance is not satisfac-
tory. Check wire sizes and length in the chart below.
Refer to the Electrical page and check your work area
for problem conditions such as the following:
• Loose or incorrect connections (see Connecting
the Motor and Changing the Motor Voltage in the
Assembly section)
• Wrong type of plug (use only 3-prong grounding
type) or receptacle (matching receptacle for 3-
prong plug)
• Reduced input voltage (too small a wire or too
many items on the circuit)
• Extension cord is too long or wrong type (use only
outdoor extension cords sized by the chart.)
• Using a dull blade or forcing a cutting operation.
,_ WARNING: Use the correct cord and plug to
prevent overload and motor burnout.

Note: This motor should be blown out or vacuumed
frequently to prevent saw dust build-up which
could interfere with motor cooling.
