SYMPTOM POSSIBLE CAUSE(S)Wheel cuts (crooked) 1. Work not positioned
2. Hand pressure too great
3. Work not secure
4. Loose abrasive wheel
5. Dull or clogged abrasive wheel
6. Wheel washer loose orworn
7. Abrasive wheel worn or chipped
CORRECTIVE ACTION1. Adjust vise angle
2. Reduce pressure
3. Tightenvise
4. Reinstall wheel according to instructionsunder
"Replacing AbrasiveWheel", page 5
5. Replace abrasive wheel
6. Tightenor replace
7. Replace abrasive wheel
Bad cuts(rough) 1. Too much hand pressure 1. Reduce hand pressure
2. Wheel clogged or damaged 2. Replace abrasive wheel
Wheel istwisting/chatters. 1. Cut is binding wheel 1. Decrease hand pressure
2. Wheel washer loose orworn 2. Tighten orreplace
3. Work notsecure 3. Tighten vise
4. Hand pressure too great 4. Reduce handpressure
Motor will notstart 1, Noelectrical power to motor
2. Low voltage
3. Defective trigger switch;
defective line cord
4. Open circuit in motor or
loose connections
5. Burned out motor
1. Short circuit in line cord or plug
2. Short circuit in motor or
loose connection
3. Incorrect fuses orcircuit breakers
in power line
4. Motor overloaded
5. Low voltage
Motor willnot start or
stalls; fuses orcircuit
breakers blow
1. Check electrical wiring to motorfor continuity
2. Check power line for proper voltage
3. Replace defective parts before using
cutoff saw again
4. Inspect lead terminals on motor for loose or
open connections
5, Anyattempt to repair this motor may create a
hazard unless repair is done by an authorized
Sears Service Center.
1. Inspect line cord or plug for damaged
insulationand shorted wires
2. Inspect all lead terminals on motor for loose
or worn insulation on wires
3. Install correct fuses or circuit breakers
4. Reduce load on motor
5. Correct the lowvoltage conditions
Motor fails to develop full 1. Power line overloaded 1. Reduce the load on the power line
power (power output of 2. Undersized wires or cords too long 2. Increase wire sizes or reduce length ofcords
motor decreases) with 3. General overloading of power 3. Request a voltage check from the
"_ecreasedvoltage at company's facilities power company
imotor terminals
'vlotor hot oroverheats 1. Motor overloaded 1. Reduce load on motor
2. Air circulation around motor 2. Unblock air vents to provide normal air
restricted circulationaround motor
3. Gears needlubrication 3. Check grease
4. Worn or dirty brushes 4. Replace or clean brushes
C/heel chipping 1. Tooheavy hand pressure 1. Decrease hand pressure
2. Narrow workpieee 2. Decrease hand pressure
3. Vibrating workpiece 3. Clamp work securely
Excessive wheel 1. Abrasive wheel not rated for saw speed 1. Use abrasive wheels rated for saw speed
oreakage 2, Misaligned abrasive wheel 2. Adjust wheel washer and nut
Premature wheel dulling 1. Inadequate hand pressure 1. Increase hand pressure
2. Hard spots or scale in/onmaterial 2. Increase hand pressure
3. Work hardening of material 3. Increase handpressure
(especially stainless steel)
