Installation and Set Up: The Model N80X uses two 2 H.P. 3 Phase, 3450 RPM, 60 Hz TEFC Motors on a NEMA 56 Frame. The Model N90X uses two 3 H.P. 3 Phase, 1725 RPM, 60 Hz TEFC Motors on a NEMA 182T Frame. - Page 4 Blade Installation: For both Model N80X & N90X: Before setting blades on spindle, disconnect power. Supply air to the machine so that blades rise to the top of the stroke. Remove front blade guard by loosening side guard wing nuts or bolts and then remove two top blade guard wing nuts.

Page 10: Air Pneumatics
N80X & N90X Air/Pneumatic System: The air pneumatic system on the N80X and N90X is simple to use and understand, and easy to operate. The main components of the air system are shown below in the Air Circuit Piping Diagram. The system operates by depressing the Foot Valve, P/N B3P71. - Page 11 An operating pressure of 75 PSI is required. (This is set at the factory.) Air Filter/Regulator Trouble Shooting the Pneumatic System for the N80X & N90X Cut-Off Saw: If there is no control over the power feed stroke: Replace either the Upstroke Flow Control Valve, or the Downstroke Control Valve P/N 9B3P65.

Page 12: Safety Instructions
Safety Instructions to the Operator: 1. KNOW YOUR CTD SAW. Read this instruction manual carefully. Learn the operation, application, and limitations, as well as the specific potential hazards peculiar to this machine. 2. Avoid accidental starting. Make sure switch is OFF before plugging in power cord. A Dual Magnetic Starter is provided to give the operator added protection. - Page 13 Mitre Cutting: (see Diagram No. 8) A fixed Double Mitre Saw, such as the N80X and N90X operates by making two 45 cuts at one time. The machine “V” notches the piece of material between the two blades. To make the first cut on a stick length;...
- Page 14 Vertical Air Clamps should be installed on the Model N80X and N90X to hold material securely. They are controlled by a 3-Way Valve mounted above the right motor on the N90X, and above the slide on the N80X. When the machine is in the rest position, the 3-Way Valve shuts the air supply to the clamps.
- Page 15 Cutting Plastic: Plastic can be cut as easily as wood on the N80X and N90X models. However, because of its elastic properties, the material can deflect as the blades pass through. Therefore it is important to clamp the material as close as possible to the blade and support it by use of fixtures.

Page 16: Preventative Maintenance
Length of Stroke Adjustment: The N80X and N90X are unique in that the travel of the air cylinder can be adjusted to eliminate extra blade movement. By adjusting the upstop bumper located above the Slide, P/N 9A06 for the N90X, and P/N 8C01 for N80X, the blades will be lowered closer to the work. -
Page 17: Repair And Service
