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).
Machine slows when oper-
ating.
Loud, repetitious noise com-
ing from machine.
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.
2. V-belts loose.
1. Pulley setscrews or keys are missing or
loose.
2. Motor fan is hitting the cover.
3. V-belts are defective.
1. Outfeed table is set too low.
1. Outfeed table is set too high.
1. Knots or conflicting grain direction in
wood.
2. Nicked or chipped carbide cutters.
3. Feeding too fast.
4. Taking too deep of a cut.
1. Wood may have high moisture content
or surface wetness.
2. Nicked or chipped carbide cutters.
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. Adjust V-belts.
1. Inspect keys and setscrews. Replace or tighten if necessary.
2. Tighten fan or shim cover.
3. Replace V-belts.
1. Align outfeed table with cutterhead knife at top dead center.
1. Align outfeed table with cutterhead knife at top dead center.
1. Inspect stock for knots and grain.
2. Inspect and replace or rotate the carbide cutters.
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 replace or rotate the carbide cutters.
