Changing The Sawblade - Jet JWBS-14Q Operating Instructions Manual

A- Regular tooth:
The most common used tooth shape. 0° rake angle.
Suited for cut-off and contour sawing of most materials. For
cutting materials where a fine cut is required.
B- Skip tooth:
Widely spaced teeth, to prevent clogging. 0°rake angle.
For resawing and ripping thick stock, especially soft woods.
C- Hooked tooth:
Large teeth and a positive rake angle, for aggressive, faster
cutting.
For resawing and ripping thick stock, especially hard woods.
D- Variable tooth:
Variable tooth shape and spacing produces smooth cuts and
dampens vibrations.
Set:
Saw teeth are bent out of the plane of the saw body, resulting
in a wide cut in the workpiece.
This helps reduce friction and allows curve cuts).
The alternate set (Y, Fig 12) is the most used for
woodworking blades.
X- Raker set
Y- Alternate set
Z- Wavy set

Blade material:
- carbon steel
- alloy steel
- bimetal (HSS teeth welded onto alloy steel blade body)
-carbide tipped.

7.2 Changing the sawblade

Check sawblade for flaws (cracks, broken teeth, bending)
before installation. Do not use faulty sawblades.
The sawblade teeth must point in cutting direction (down)
Always wear suitable gloves when handling sawblades.
To remove the blade:
Open the wheel covers.
Remove the table pin (F, Fig 14) and the table insert.
Release the blade tension by operating the quick blade
tension lever (Q, Fig 16) and by turning the blade tension
