TROUBLESHOOTING
SYMPTOM
Motor does not start
Motor stalls (resulting in blown fuses or
tripped circuit breakers)
Motor starts slowly or fails to come
to full speed
Motor running too hot
Frequent opening of fuses or circuit breakers
Snipe (gouging at end of boards)
Uneven depth of cut
45° cuts inaccurate
Fuzzy grain
Torn grain
POSSIBLE CAUSES
1. Defective switch
2. Defective motor
3. Low line voltage
1. Circuit overloaded
2. Low line voltage
3. Motor overloaded
4. Incorrect fuses on circuit breakers
5. Short circuit in motor; loose connections
or worn insulation on lead wires
6. Clogged wood chips
1. Defective motor windings
2. Clogged wood chips
1. Motor overloaded
2. Restricted air circulation due to dust
accumulation
1. Motor overloaded
2. Fuses or circuit breakers do not have
sufficient capacity
3. Circuit overloaded
1. Dull blades
2. Inadequate support of long boards
3. Uneven feed
1. Blade height not uniform
2. Fence not perpendicular to jointer bed
3. Feeding wood too fast
1. Fence stops not adjusted properly
2. Fence bottom not even with outfeed table
due to wood chips under fence
Planing wood with high moisture
1. Too heavy a cut
2. Blades cutting against grain
3. Dull blades
CORRECTIVE ACTION
1. Have switch replaced
2. Have motor replaced/repaired
NOTE:
1 and 2 must be done by a qualified
service technician
3. Correct low line voltage condition
1. Reduce circuit load (turn off other
appliances)
2. Correct low line voltage conditions
3. Reduce load on motor
4. Have correct fuses or circuit breakers
installed
5. Inspect terminals in motor for damaged
insulation and shorted wires and have
them replaced
6. Take shallow depth of cut and attach a
shop-vac to exhaust port. Inspect chip
blower assembly and fan belt
1. Have motor replaced/repaired
2. Take shallow depth of cut and attach a
shop-vac to exhaust port. Inspect chip
blower assembly and fan belt
1. Reduce load on motor
2. Clean dust and restore normal air
circulation
1. Reduce load on motor
2. Have correct fuses or circuit breakers
installed
3. Reduce circuit load (turn off other
appliances)
1. Replace or sharpen blades. See
“Sharpening Blades,” page 9
2. Support long boards. See “Recommended
Accessories,” page 15
3. See “Feeding Workpiece,” page 7
1. Adjust blade height. See “Adjusting Blade
Height,” page 7
2. See “Install Fence and Fence Bracket to
Jointer,” page 3
3. Feed wood slower
1. Adjust fence stops. See “Install Fence and
Fence Bracket to Jointer,” page 3
2. Clean wood chips from underside of fence
Remove high moisture content from wood
by drying
1. Reduce depth of cut
2. Feed work along grain
3. Replace or sharpen blades
