circuit breakers

Motor problems 
in general

Teeth ripping from blade

Motor running too hot

Coolant does not flow

Excessive blade breakage

Premature blade dulling

POSSIBLE CAUSES

1. Motor overloaded

2. Air circulation around motor restricted

1. Short circuit in motor; connections loose; or

shorted terminals or worn insulation on lead wires

3. Too slow speed

4. Vibrating workpiece

5. Gullets loaded

1. Blade tension too high

2. Blade too coarse for work (pipes especially)

3. Blade too fine for work (heavier, soft material)

4. Gears need lubrication

1. Pump motor burned out

2. Dirty screen/filter on pump

3. Coolant level too low

1. Material loose in vise

2. Incorrect speed or feed

3. Teeth too coarse for material

4. Incorrect blade tension

5. Teeth in contact with work before 

saw is started

6. Blade rubs on wheel flange

7. Misaligned guides

8. Blade too thick for wheel diameter

1. Teeth too coarse

2. Too much speed

3. Inadequate feed pressure

4. Hard spots or scale in/on material

5. Work hardening of material (especially 

stainless steel)

6. Blade installed backwards

7. Insufficient blade tension

CORRECTIVE ACTION

1. Reduce load on motor

2. Clean motor to provide normal air circulation

around motor

1. Inspect terminals in motor for damaged insulation

and shorted wires

2. Correct the low line voltage conditions

3. Install correct fuses or circuit breakers

4. Reduce load on motor

1. Reduce load on motor

2. Install correct fuses or circuit breakers

To troubleshoot and service motor consult 
qualified technician

1. Use finer tooth blade

2. Decrease feed pressure

3. Increase speed

4. Clamp work securely

5. Use coarse tooth blade or use brush to 

remove chips

1. Reduce tension on blade

2. Use finer tooth blade

3. Use coarser tooth blade

4. Check oil bath

1. Replace pump

2. Clean

3. Refill coolant tank

1. Clamp work securely

2. Check Machinist Handbook

3. Check Machinist Handbook for recommended

blade type

4. Adjust to where blade does not slip on wheel

5. Place blade in contact with work after motor 

is started

6. Adjust tracking

7. Adjust guide bearings

8.  Use thinner blade

1.  Use finer tooth blade

2.  Try next lower speed

3.  Decrease spring pressure

4.  Reduce speed, increase feed of saw

5.  Increase feed pressure by reducing 

spring tension

6.  Remove blade, twist inside out and reinstall blade

7.  Increase tension to proper level
