MOTOR SAFETY PROTECTION
This motor should be blown out or vacuumed frequently to
prevent sawdust buildup which can interfere with normal
motor ventilation.
 Connect this tool to a power source with the appropriate
voltage for your model and a 15-amp branch circuit with
a 15-amp time delay fuse or circuit breaker. Using the
wrong size fuse can damage the motor.
 If the motor won’t start, turn off the power switch
immediately and unplug the tool. Check the cutterhead
to make sure it turns freely. If the head is free, try to start
the motor again. If the motor still does not start, refer to
the Troubleshooting section.
Frequent “blowing” of fuses or tripping of circuit breakers
may result if:

Improper or dull blades are used.
NOTE: Do not continuously use the thickness planer set
at maximum depth of cut (1/8 in.) and at full 13 in. width
of cut. Continuous use at maximum cutting capacity will
damage your motor.
 Motor is overloaded. Overloading can occur if a workpiece
is fed too rapidly or if the tool is misaligned.
 Motor circuit is fused differently from recommendations.
Always follow instructions for the proper fuse / breaker.
Do not use a fuse/breaker of greater capacity without
consulting a qualified electrician.
 Low voltage. Although the motor is designed for operation
on the voltage and frequency specified on the motor,
normal loads will be handled safely on voltage no more
than ten percent above or below that figure. Heavy loads,
however, require that voltage at motor terminals equal the
voltage specified on the motor.
NOTE: Always check the connections, the load, and the
supply circuit whenever the motor fails to perform satis-
factorily.

MOTOR OVERLOAD PROTECTOR
See Figure 2.
WARNING:
To reduce the risk of serious personal injury from
thrown objects or blade contact from unexpected
starting, immediately turn off the tool if the
protector stops the motor. Remove the switch
key and allow the motor time to cool.
This planer is equipped with a overload protector device
which will automatically “trip” and cause the planer to shut
down if the motor is overheating due to continuous heavy
cutting.
The planer overload protector can only be reset manually
by the user after the planer has been allowed to adequately
cool. Allow 15 - 30 minutes.
Should the overload protector “trip”:

Turn switch OFF ( O ).
 Raise carriage and remove board.
 After 15 - 30 minutes, reset the overload protector by
pushing the red reset button on the front of the tool. An
audible click will indicate the overload protector is reset.
Once the button is reset, the tool may be started and
operated as normal.
NOTE: If the red button won’t click into place immediately,
the motor is still too hot and must be allowed to cool.
 If motor has cooled, button will remain in.
