2. Hand pressure too great
3. Work not secure
4. Loose abrasive wheel
5. Dull or clogged abrasive wheel
6. Wheel washer loose or worn
7. Abrasive wheel worn or chipped
CORRECTIVE ACTION
1. Adjustvise angle
2. Reduce pressure
3. Tighten vise
4. Reinstall wheel according to instructionsunder
"Replacing Abrasive Wheel", page 5
5. Replace abrasive wheel
6. Tighten or 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 is twisting/chatters. 1. Cut is binding wheel 1. Decrease hand pressure
2. Wheel washer loose or worn 2. Tighten or replace
3. Work not secure 3. Tighten vise
4. Hand pressure too great 4. Reduce hand pressure
Motor will not start
1, No electrical 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 or circuit breakers
in power line
4. Motor overloaded
5. Low voltage
Motor will notstart or
stalls; fuses or circuit
breakers blow
1. Check electrical wiringto 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, Any attempt to repair thismotor may create a
hazard unless repair is done byan 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 low voltage 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 of cords
motor decreases) with 3. General overloading of power 3. Request a voltage check from the
"_ecreased voltage at company's facilities power company
imotor terminals
'vlotor hot or overheats 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 need lubrication 3. Check grease
4. Worn or dirty brushes 4. Replace or clean brushes
C/heel chipping 1. Too heavy 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/on material 2. Increase hand pressure
3. Work hardening of material 3. Increase hand pressure
(especially stainless steel)
