Because of the importance of blade selection, it
is recommended that you use the blade
selection guide on page 21.
When cutting, do not
overfeed the blade; overfeeding will reduce
blade life, and may cause the blade to break.
Blade Breakage
Band saw blades are subject to high stresses
and breakage may sometimes be unavoidable.
However, many factors can be controlled to help
prevent most blade breakage. Here are some
common causes for breakage:
1. Misalignment of the blade guides
2. Feeding work too fast
3. Using a wide blade to cut a short radius
curve
4. Excessive tension
5. Teeth are dull or improperly set
6. Upper guides are set too high off the
workpiece
7. Faulty weld on blade
Making Cuts
1. Make sure blade is adjusted correctly for
tension and tracking.
2. Adjust blade guard so that it is just above
the workpiece (about 3/16"), allowing
minimum exposure to the blade.
3. Move the fence into position.
4. Feed the stock slowly, with the straightest
edge against the fence. DO NOT FORCE
the workpiece into the blade.
Whenever possible, use a
push stick, hold-down, power feeder, jig, or
similar device while feeding stock to prevent
your hands getting too close to the blade.
NOTE: When cutting long stock, the operator
should use roller stands, support tables, or an
assistant to help stabilize the workpiece.
Maintenance
Before any intervention on
the machine, disconnect it from the electrical
supply by pulling out the plug. Failure to
comply may cause serious injury.
Keep bearing guides clean and free of build-up.
Check that the cleaning brush over the band
wheel is working properly, and remove any
deposits from the band wheels to avoid vibration
and blade breakage.
The table surface should be kept clean and free
of rust for best results. Some users prefer a
paste wax coating. Another option is talcum
powder applied with a blackboard eraser rubbed
in vigorously once a week; this will fill casting
pores and form a moisture barrier. This method
provides a table top that is slick and allows rust
rings to be easily wiped from the surface.
Important also is the fact that talcum powder will
not stain wood or mar finishes as wax pickup
does.
Do not let saw dust build up in the upper and
lower wheel housings. Vacuum out frequently.
Connect the bandsaw to a JET dust collection
system.
Clean and grease the raising/lowering rack for
the upper bearing guides if it becomes difficult to
raise or lower.
Clean and oil the tensioning mechanism if it
becomes difficult to adjust.
Vacuum out the motor fan cover.
