c. Hook Tooth – Similar to skip tooth except teeth have positive rake. Effective in
sawing non-ferrous metals and large ferrous sections when heavy feed pressures
are required.
3. Tooth Spacing
a. Tooth spacing is determined by hardness of material and/or the cross-section.
The harder the material, the more teeth per inch. Thin cross-sections require more
teeth to avoid straddle. Rule: at least 3 teeth in contact with work.
4. Tooth Set
a. Raker – Most widely used. Consists of a repeated pattern of one tooth set left, one
right and one tooth straight. Recommended for production cutting where material
is of uniform size, shape, and type.
b. Wavy – Has groups of teeth set alternately to the left and to the right forming a
wave-like pattern. Used for cutting thin stock or where the work varies such as in
pipe, angles, channels, and extrusions.
BLADE REMOVAL
1. Raise frame a few inches above the bed and close feed cylinder valve to hold frame up.
2. Remove the necessary guarding and blade cleaning brushes.
3. Turn blade tension screw counterclockwise and pull the idle wheel toward the center of
the machine.
4. Push blade down, out of blade guides and remove blade from machine.
BLADE INSTALLATION
1. Raise frame a few inches above bed and close the feed cylinder valve to hold frame up.
2. Remove necessary guards and blade cleaning brushes.
3. Turn blade tension screw counterclockwise and pull idle wheel toward center of machine.
4. Grasp blade in center forming two loops. From rear of machine place blade loops under
wheels and rest the near portion on right front blade guard. CAUTION: BE SURE TO
WEAR GLOVES WHEN HANDLING BLADES.
5. Push blade up into blade guides. CAUTION: BE AWARE OF HYDRAULIC & COOLANT
LINES.
6. Fit blade up against flanges of the idle and drive wheels and tighten tension screw
enough to hold blade in place. Depress side of blade near rear blade guard to hold blade
on wheels while tightening tension screw.
