This is the reason of an increasing demand for a cutter equipped with a tipped saw blade and free from the above problems. The new Model CD 14F is a highly efficient and long-life dry cut metal saw equipped with a tipped saw blade for metal cutting.
(2) Equipped with tipped saw blade for metal cutting The Model CD 14F is far superior to the conventional high-speed cutters (cutting with grindstones) in cutting performance thanks to the tipped saw blade for metal cutting. This tipped saw blade has a unique relief angle to cause minor chipping when the cutting edge becomes worn for long-lasting cutting quality, and has about 1.5 times longer service life than those of the competitors.
(3) Quick-lock vise The Model CD 14F is equipped with the quick lock vise ass'y that can securely fasten a workpiece just by tilting the clutch toward vise (A) (to screw-fit the clutch) and turning the screw handle, and quickly release the vise (A) just by tilting the clutch backward (to release the screw-fitted clutch).

7-2. Precautions of the Nameplate Each Model CD 14F is furnished with a nameplate that lists the following precautions. (1) Advise the customer to become thoroughly familiar with the contents of the Instruction Manual before attempting to operate the machine.
7-4. Warning Label (B) Warning label (B) is affixed on the lower portion of warning label (A). Please instruct customers to strictly observe the contents from 1 to 12 in warning label (B) shown at the left. Fig. 6 7-5. Grounding Instructions In the event of a malfunction or breakdown, grounding provides a path of least resistance for electric current to reduce the risk of electric shock.
Fig. 9-A Fig. 9-B (2) Features of the tipped saw blade The Model CD 14F's tipped saw blade features: A unique relief angle to cause minor chipping when the cutting edge becomes worn for long-lasting cutting quality Trapezoidal teeth for precise straight cutting Cut-limiting tooth form to limit the maximum cutting depth for prevention of chipping These features are described in more detail below.
Trapezoidal teeth are superior to alternating teeth in service life and accuracy, and alternating teeth are superior to trapezoidal teeth in cutting quality. The Model CD 14F adopts the tipped saw blade with Alternating teeth trapezoidal teeth to assign priorities to service life and accuracy.
8-5. Angle Cutting The Model CD 14F is capable of angle cutting up to an angle of 45 degrees. Angle setting of vise (B) can be accomplished by loosening the bolt M10 and the hex. head screw with the accessory 17 mm wrench, and aligning the indicator with the described angle setting on the angle graduation scale.
Depending on working conditions, ear plugs, a dust mask and other safety devices may also be necessary. (2) Be sure to ground the Model CD 14F according to "7.5 Grounding Instructions" to reduce the risk of electric shock in the event of a malfunction or breakdown.
