SYMPTOM
Motor will not start.
Motor will not start; fuses or
circuit breakers blow.
Motor overheats.
Motor stalls (resulting in
blown fuses or tripped cir-
cuit).
Cutterhead slows when
operating.
Snipe (gouge in the end of
the board that is uneven
with the rest of the cut).
Workpiece stops in the mid-
dle of the cut.
Chipping.
Fuzzy grain.
POSSIBLE CAUSE
1. Low voltage.
2. Open circuit in motor or loose connec-
tions.
1. Short circuit in line cord or plug.
2. Short circuit in motor or loose connec-
tions.
3. Incorrect fuses or circuit breakers in
power line.
1. Motor overloaded.
2. Air circulation through the motor
restricted.
1. Short circuit in motor or loose connec-
tions.
2. Low voltage.
3. Incorrect fuses or circuit breakers in
power line.
4. Motor overloaded.
1. Applying too much pressure to work-
piece.
1. Outfeed table is set too low.
1. Outfeed table is set too high.
1. Knots or conflicting grain direction in
wood.
2. Dull knives.
3. Feeding too fast.
4. Taking too deep of a cut.
1. Wood may have high moisture content
or surface wetness.
2. Dull knives.
CORRECTIVE ACTION
1. Check power line for proper voltage.
2. Inspect all lead connections on motor for loose or open connec-
tions.
1. Inspect cord or plug for damaged insulation and shorted wires.
2. Inspect all connections on motor for loose or shorted terminals
or worn insulation.
3. Install correct fuses or circuit breakers.
1. Reduce load on motor.
2. Clean out motor to provide normal air circulation.
1. Inspect connections on motor for loose or shorted terminals or
worn insulation.
2 Correct the low voltage conditions.
3. Install correct fuses or circuit breakers.
4. Reduce load on motor.
1. Feed workpiece slower.
2. Tighten V-belts.
1. Align outfeed table with cutterhead knife or carbide cutters at top
dead center. See
page 29.
1. Align outfeed table with cutterhead knife or carbide cutters at top
dead center. See
page 29.
1. Inspect stock for knots and grain.
2. Inspect and sharpen cutterhead knives.
3. Slow down the rate that you feed the wood into the cutterhead.
4. Raise the infeed table to take a smaller depth of cut. Never
exceed
1 ⁄
8
" per pass when edge jointing or 1 ⁄
32
" when surface
planing. Reduce cutting depth for harder woods.
1. Check moisture content and allow to dry if moisture is too high.
2. Inspect and sharpen cutterhead knives.
Troubleshooting Guide
Disconnect power to the
machine when perform-
ing any maintenance or
repairs. Failure to do this
may result in serious
personal injury.
