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
POSSIBLE
CAUSE(S)
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
Motor running too hot
1. Motor overloaded
2. Restricted air circulation due to
dust accumulation
Frequent opening of fuses or
circuit breakers
Snipe
(gouging at end of boards)
Uneven depth of cut
45 ° cuts inaccurate
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
CORRECTIVE
ACTION
1. Have switch replaced
2. Have motor replaced/repaired
NOTE: 1 and 2 must be done by a qualified
service technician; Consult Sears service.
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 10
2. Support long boards.
See "Recommended
Accessories," page 17
3. See "Feeding Workpiece," page 8
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
Fuzzy grain
Planing wood with high moisture
Remove high moisture content from wood by
drying
Torn grain
1. Too heavy a cut
1. Reduce depth of cut
2. Blades cutting against grain
2. Feed work along grain
3. Dull blades
3. Replace or sharpen blades
