SYMPTOM

Blade cuts (crooked)

Bad cuts (rough)

Blade is twisting
Unusual wear on side or
back of blade

Motor will not start

Motor will not start; 
fuses or circuit 
breakers blow

Motor fails to develop full
power  (power  output of
motor decreases rapidly)
with decreased voltage at
motor terminals

POSSIBLE CAUSES

11. Guide bearing worn

1. Too much speed or feed

2. Blade has too few teeth per inch

1. Cut is binding blade

2. Blade guides worn

3. Blade guide bearings not adjusted properly

4. Blade guide bearings not adjusted properly

5. Feed pressure too great

1. No electrical power to motor

2. Low voltage

3. Defective On/Off switch; defective line cord

4. Open circuit in motor or loose connections

5. Motor protector open (only if your motor is

equipped with an overload protector)

6. Burned out motor

7. Limit switch closed

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

1. Power line overloaded

2. Undersized wires or cords too long

3. General overloading of power company’s 

facilities

CORRECTIVE ACTION

1. Adjust vise to be square with blade

2. Reduce pressure by increasing spring tension

3. Adjust guide bearings 

4. Increase blade tension a little at a time

5. Move guides as close to work as possible

6. Replace blade

7. Check page 6 for recommended speeds

8. Tighten

9. Tighten

10. Track blade properly according to instructions

under Operation, pages 6

11. Replace

1. Reduce speed or feed

2. Replace with finer tooth blade

1. Decrease feed pressure

2. Replace

3. Adjust guide bearings (see page 5)

4. Tighten bearings

5. Reduce feed pressure

1. Check electrical wiring to motor for continuity

2. Check power line for proper voltage

3. Replace defective parts before using band saw

again

4. Inspect lead terminals on motor for loose or open

connections

5. Reset protector after motor has cooled

6. Replace motor

7. Raise head to open limit switch

1. Inspect line cord or plug for damaged 

insulation and 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

1. Reduce the load on the power line

2. Increase wire sizes or reduce length of cords

3. Request a voltage check from the power 

company
