Troubleshooting Guide
Problem Possible Cause Possible Solution
If the material does not feed properly Check for dull knives. Rotate or replace as necessary. Refer to Changing the Planer
Knives section.
Check for excess clogging in the
dust shroud.
Refer to Periodic Maintenance and Figures P–R in the Changing
or Rotating the Planer Knives section.
Check for excess oil/debris/pitch on
feed rollers.
Refer to Periodic Maintenance and Cleaning paragraphs under
the Maintenance section.
Check for excessively twisted, cupped
or bowed material.
Refer to Twisted, Cupped and Bowed Wood paragraph in the
Basic Planing section.
Check for a broken drive belt. Refer to Replacing the Drive Belt paragraph in the
Maintenance section.
If the circuit breaker trips repeatedly Dull knives Dull knives can cause motor overloading, rotate or replace as
necessary. Refer to Changing the Planer Knives section.
NOTE: Circuit breaker overload is often the result of dull knives.
If the circuit breaker on your planer trips, check the sharpness
of your knives before attempting to reset the breaker in order to
continue planing.
The depth of cut is higher. An overly aggressive cut could cause motor overloading. Refer
to the Depth Adjustment paragraph in the Assembly and
Adjustments section and Material Removal Gauge paragraph
in the Operation section.
The feed rate is higher. Drop feed rate to 14 ft/min. A reduction in feed rate will reduce the
load on the motor and prevent breaker trips.
If the unit does not run Check to see if the unit is plugged in. Ensure unit is plugged into the appropriate outlet, refer to the
General Safety Instructions section.
Check to see if the top cover is
properly in place.
Refer to Figure P for proper location.
Check to see if the dust shroud is
properly in place.
Refer to After Installing New Knives.
Check to see if the circuit breaker
needs to be reset.
Refer to Circuit Breaker Reset Button paragraph under the
Maintenance section.
Check to see if the motor brushes
are depleted.
Refer to Brushes paragraph under the Maintenance section.
If chips do not eject from the rear of
the unit
Check for excess clogging in the
dust shroud and fan..
Refer to Periodic Maintenance and Chip Ejection Fan
paragraphs in the Maintenance section.
Check to see if the dust shroud is
properly in place.
Refer to After Installing New Knives.
If the branch (house/shop) circuit
breaker trips repeatedly
Even under normal loading conditions,
other electrical loads on the same
branch circuit may cause the circuit
breaker to trip.
Unplug or turn off other devices sharing the circuit with the planer
OR use the planer on another branch circuit by itself.
Dull knives Dull knives can cause motor overloading, rotate or replace as
necessary. Refer to Changing the Planer Knives section.

to the Depth Adjustment paragraph in the Assembly and
Adjustments section and Material Removal Gauge paragraph
in the Operation section.
