TROUBLE SHOOTING CHART
Blade is twisting
1.Cut is binding blade
2.Too much blade tension
1.Decrease feed pressure
2.Decrease blade tension
Symptom
Possible Cause (s)
Corrective Action
Excessive Blade
Breakage
1.Material loose in vise
2.Incorrect speed or feed
3.Blade teeth spacing too large
4.Material too coarse
5.Incorrect blade tension
6.Teeth in contact with material before
saw is started
7.Blade rubs on wheel flange
8.Misaligned guide bearings
9.Cracking at weld
1.Clamp work securely
2.Adjust speed or feed
3.Replace with a smaller teeth spacing
blade
4.Use a blade of slow speed and small
teeth spacing
5.Adjust so blade doesnot slip on wheel
6.Place blade correctly in relation with
workpiece
7.Adjust wheel alignment
8.Adjust guide bearings
9.Weld again
Premature Blade
Dulling
1.Teeth too coarse
2.Too much speed
3.Inadequate feed pressure
4.Hard spots or scale on material
5.Work hardening of material
6.Blade twist
7.Insufficient blade
1.Use finer teeth
2.Decrease speed
3.Decrease spring tension on side of saw
4.Reduce speed, increase feed pressure
5.Increase feed pressure by reducing
spring tension
6.Replace with a new blade and adjust
blade tension
7.Tighten blade tension adjusting knob
Unusual Wear on
Side/Back of Blade
1.Blade guides worn
2.Blade guide bearings not adjusted
properly
3.Blade guide bearing bracket is loose
1.Replace
2.Adjust as per operator's manual
3.Tighten
Teeth Ripping from Blade
1.Tooth too coarse for work
2.Too heavy pressure, too slow speed
3.Vibrating workpiece
4.Gullets loading
1.Use finer tooth blade
2.Decrease pressure, increase speed
3.Clamp workpiece securely
4.Use coarse tooth blade or brush to remove
chips
Motor running too hot
1.Blade tension too high
2.Drive belt tension too high
3.Gears need lubrication
4.Cut is binding blade
5.Gears aligned improperly
1.Reduce tension on blade
2.Reduce tension on drive belt
3.Check oil bath
4.Decrease feed and speed
5.Adjust gears so that worm is in center
of gear
Bad Cuts
1.Feed pressure too great
2.Guide bearing not adjusted properly
3.Inadequate blade tension
4.Dull blade
5.Speed incorrect
6.Blade guide spaced out too much
7.Blade guide assembly loose
8.Blade truck too far away from wheel
flanges
1.Reduce pressure by increasing spring
tension on side of saw
2.Adjust guide bearing, the clearance can
not be greater than 0.2mm.
3.Increase blade tension by adjust blade
tension
4.Replace blade
5.Adjust speed
6.Adjust guides space
7.Tighten
8.Re-track blade according to operating
instructions
Bad Cuts
(Rough)
1.Too much speed or feed
2.Blade is too coarse
3.Blade tension loose
1.Decrease speed or feed
2.Replace with finer blade
3.Adjust blade tension
