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

connections or worn insulation
on lead wires
6. Clogged wood chips
1. Defective motor windings
2. Clogged wood chips

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

2. Fence bottom not even with
outfeed table due to wood chips
under fence
Planing wood with high moisture

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
