1.0 INTRODUCTION The CPO-315 HFA-NF Fully Automatic Cold Saw is a high speed saw designed to cut solids, tubes, flats and other profiles in grades of nonferrous material that range from aluminum, brass, copper, synthetics and extrusions. Cold sawing is a process similar to a milling process. In most cases, this gives a finished cut that does not require any secondary machining or de-burring.

4.4 COOLANT SYSTEM The coolant system on this machine is a pneumatic mist type. We recommend using only our P/N 075760, SYNCON-2 coolant in this saw. One gallon of coolant is shipped with the saw. For the best results, we recommend that it is used straight and not diluted. The NF coolant reservoir has a capacity of (5) quarts (4.7 liters).
5.0 MACHINE START-UP Before starting this machine, take the time to review the operator’s manual thoroughly, to familiarize yourself with all of the functions of the machine. We strongly urge you to follow OSHA directive CFR-1910.147 (effective 09-09-90) regarding lock-out, tag-out procedures.
Page 15
5.1A MAIN POWER SWITCH This is the main power disconnect switch for the machine and it should be locked or tagged in the OFF position any time maintenance or service work is being performed. Maintenance or service work on the electrical controls must be performed by qualified personnel.
Page 16
5.1F HEAD DOWN This button is also used to set the overall stroke of the machine and to make manual cuts. 5.1G HITCH SELECTOR This switch is used to select the number of hitches the shuttle vise makes before the saw makes a cut. POSITION 1 is for parts from 0 to thirty inches in length.
Page 17
5.1L POWER INDICATOR LIGHT This switch indicates that the main switch (A) is on and that there is power to the control panel. 5.1M COUNTER This counter can be programmed to count up or down, depending on your preference. The counter is programmed from the factory to count up.

6.0 MACHINE OPERATION 6.1 BLADE INSTALLATION SEE FIGURE 4 BELOW. CAUTION: THIS MACHINE IS DESIGNED TO USE CARBIDE TIPPED BLADES, ONLY. USE ONLY BLADES DESIGNED FOR THIS MACHINE. DO NOT USE BLADES DESIGNED FOR THIS MACHINE ON ANY OTHER EQUIPMENT. THE MAXIMUM RPM’S FOR THESE BLADES ARE 4,000.
Page 20
The CPO-315-HFA-NF saw is designed to use a maximum 12 inch (300mm) diameter blade. The arbor size is 40mm with two 8mm pins spaced at 55mm. BEFORE INSTALLING THE BLADE, make sure that the power to the machine is off.
6.2 SAW CAPACITIES SEE FIGURE 5 BELOW. Figure 5 below is a chart showing the maximum capacities of this machine in various materials. RFA/ST RFA/ST CAPACITIES WITH MAXIMUM DIAMETER 90° ONLY 90° ONLY BUNDLE FEED BLADES 315 MM INCHES Ø3-1/2 Ø3 Ø3 Ø89...

Page 24
The following are set-up and maintenance instructions for the material vise. Make sure that the filter/lubricating device (A) is full of oil. Use a quality (ISO 22) air line lubricant designed for automatic oilers. Slide the shuttle valve (F) on the filter/lubricating device down to the closed position. Connect the air supply to the shuttle valve.
6.5 SHUTTLE VISE AND CYLINDER REFER TO FIGURE 6 ON PAGE 22. CAUTION: ALWAYS DISCONNECT THE AIR SUPPLY BEFORE REMOVING THE FILLER PLUG FROM THE RESERVOIR. IF THE FILLER PLUG IS REMOVED WHILE THE MACHINE IS CONNECTED TO AIR PRESSURE, THE FLUID IN THE TANK WILL BE PURGED THROUGH THE OPENING UNDER PRESSURE.
6.6 POWER DOWN FEED REFER TO FIGURE 8 BELOW. FIGURE 8 Page 26...
Page 28
CAUTION: ALWAYS DISCONNECT THE AIR SUPPLY BEFORE REMOVING THE FILLER PLUG FROM THE RESERVOIR. IF THE FILLER PLUG IS REMOVED WHILE THE MACHINE IS CONNECTED TO AIR PRESSURE, THE FLUID IN THE TANK WILL BE PURGED THROUGH THE OPENING UNDER PRESSURE. BEFORE POWERING THE SAW, check the oil level in the reservoir (A).
6.7 MATERIAL CLAMPING All work pieces must be clamped securely in the vise. Any slippage of the material can result in broken or damaged blades. The material should be clamped so that the contact surface between the material and the blade is as small as possible. For this reason, when cutting flat stock material, we recommend standing it up and cutting it through the thinnest section, whenever possible.
Page 32
THE COUNTER ON THIS MACHINE CAN BE SET TO COUNT EITHER UP OR DOWN. TO SET THE COUNTER, USE THE FOLLOWING STEPS: To enter the programming mode, depress the reset button (A), along with buttons 5 and 6. On the lower line of the display, the message INIT appears with a down counter subtracting from five to zero seconds.
Page 34
The following instructions are to set up a job for automatic operation. Make sure that you are familiar with the functions of all of the switches and buttons before proceeding. Set the shuttle vise indicator to the desired length by loosening the moving stop (M) and then, move it to the length desired on the scale and re-tighten it.
8.0 MAINTENANCE 8.1 LUBRICATION SEE FIGURE 12 BELOW. Grease the head pivot pin (C) and the spindle shaft with a high pressure, high temperature, bearing grease daily. Apply oil to the shuttle vise guide shafts daily. Clean the chips out of the vise at least once a day; more often, if needed. Apply penetrating oil to the spindle and guide pins.
8.2 CUTTING OILS AND LUBRICANTS SECTION 12.2 lists Scotchman's part numbers for cutting oils and lubricants. Using high quality lubricants and oils will greatly increase the life of this equipment. We recommend using only our P/N 075760 - SYNCON-2 straight - not diluted.

Replacing the spindle or spindle bearings on this machine is not an easy task. You may want to consider ordering the spindle shaft assembly, which includes parts E, F, G, H, I, J, K, L and P. TO REMOVE THE SPINDLE, USE THE FOLLOWING STEPS: Remove the lock nut (C) and pull the belt sprocket (D) off the end of the shaft.
Disconnect the machine’s power and the air supply. Remove the spindle shield (XX) and the spring (Y) and ball (HH). Remove the bolts (A & B) and the retainer (D). Remove the clevis pin (F) and remove the clevis (E) and the forks (CC). The spindle can now be removed from the machine.
Page 42
TO REPLACE THE VISE SPINDLE: Remove the jam nut (GG), the set screw (H), the spring (FF) and the ball (G). Remove the jam nut (A) and the boss (B) from the end of the spindle. Disconnect the air lines and the proximity switch from the cylinder. The air connections on the cylinder are snap connectors.
9.0 OPTIONAL EQUIPMENT 9.1 SPECIAL VISE JAWS Special vise jaws for holding thin wall round tubes, profiles and bundles are available on a made-to-order basis. For prices and delivery on special jaws, contact your local dealer or the factory. For examples, REFER TO FIGURE 7 ON PAGE 25. 9.2 OPTIONAL IN FEED SUPPLY TRACKS A ten foot roller supply track, that can be installed on the input side of the saw to support longer pieces of material, is an available option for this saw.
10.0 TROUBLE SHOOTING GUIDE 10.1 ELECTRICAL TROUBLE SHOOTING 1. THE MOTOR WILL NOT RUN. The main disconnect switch in the base cabinet must be on and the emergency stop switch must be pulled out. The MOTOR switch must be in the ON position to start the saw motor. The MANUAL/AUTO switch must be in the MANUAL position to start the machine.
Do not apply excessive down pressure on the work piece. Excessive down pressure will cause the teeth to remove too large of a chip, resulting in premature dulling or blade breakage. Use a good quality synthetic coolant. We recommend using our P/N 075760 - SYNCON-2 coolant straight and not diluted.
10.4 COOLANT SYSTEM IF COOLANT WILL NOT FLOW: Check the nozzle on the end of the mister and make sure that it is turned on. Check the suction line between the reservoir and the mister unit. If there are any cracks or poor connections on the line, it will not siphon the coolant out of the reservoir.
Page 48
The PLC on this machine has a readable screen on it that can be used to diagnose most problems that may be encountered with the machine. The main controller has 12 inputs numbered I-1 TO I-12 and 6 outputs numbered Q-1 to Q-6. It also has an auxiliary controller with 12 inputs numbered R-1 to R-12 and 6 outputs numbered S-1 to S-6.
10.6 PNEUMATIC SYSTEM REFER TO FIGURE 18 ON THE FOLLOWING PAGE. THE MOST COMMON PNEUMATIC/HYDRAULIC PROBLEMS ARE: Low levels of fluid in the reservoirs: The fluid level in the power down feed reservoir should be approximately 1-1/2 inches below the top of the reservoir with the head in the down position and 2-1/2 inches below the top of the reservoir when the head is in the up position.
