1.0 INTRODUCTION The CPO 350-NF 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, combined with the self centering vise feature, gives a finished cut that does not require any secondary machining or de-burring.
2.0 SAFETY PRECAUTIONS Any individual operating this machine must be qualified, responsible and well instructed. THIS MANUAL IS NOT INTENDED TO TEACH UNTRAINED PERSONNEL HOW TO OPERATE EQUIPMENT. Never operate this machine with the blade guard removed or disconnected. This machine is designed for nonferrous material only.
3.0 WARRANTY Scotchman Industries, Inc. will, within three years of the date of purchase, replace F.O.B. the factory or refund the purchase price for any goods which are defective in materials or workmanship, provided the buyer, at the seller’s option, returns the defective goods freight and delivery prepaid to the seller, which shall be the buyer’s sole and exclusive remedy for defective goods.

6.4 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.
6.5 MITER LOCKING DEVICE SEE FIGURE 11 ON THE FOLLOWING PAGE. All models manufactured for domestic sales are equipped with a miter locking device which allows quick set-up for mitering at 45 degrees left and right and 90 degrees for straight cutting. A miter locking device is available as an option for models manufactured for international sales.
7.0 OPTIONAL EQUIPMENT 7.1 POWER VISE The power vise is an option that is normally ordered with the saw. A retrofit kit is available from your local dealer or the factory. The kit includes all parts required, plus complete installation instructions. The power vise allows automatic clamping of the material, which improves productivity and reduces operator fatigue.
Page 32
TO ADJUST THE VISE TO THE SIZE OF MATERIAL BEING CUT: Release the locking collar (D) on the vise spindle. The vise spindle is left hand threaded and the locking collar must be turned clockwise to release it. Open the vise, using the positioning handle (E), and place the material in the vise. Crank the vise closed to within approximately 1/8 of an inch (3mm) from the material and re-lock the locking collar (D).
7.1B REPLACING THE SPINDLE IN THE AIR VISE SEE FIGURE 13 ON THE FOLLOWING PAGE. Disconnect the machine’s power and air supply. Remove the air lines (A) from the front of the cylinder. Remove the support block (B) and the bolts (C) from the base of the vise. Remove the guide pins (D) out through the back of the vise.
7.1C REPLACING THE SEALS IN THE AIR VISE SEE FIGURE 14 ON FOLLOWING PAGE. Open the vise to its full open position. Disconnect the air lines from the cylinder. Remove the jam nut (G), the hand wheel (B) and the locking collar (C) from the front of the spindle.
7.2 POWER DOWN FEED The power down feed option, used in conjunction with the power vise option, changes a manual saw into a semi-automatic saw. These options will increase productivity and reduce operator fatigue. The power down feed option cannot be retrofit to machines with serial number 11940491 and prior in the field.
7.2B STROKE CONTROL ADJUSTMENT (POWER DOWN FEED) SEE FIGURE 16 ON THE FOLLOWING PAGE. Before powering the machine, the up and down stroke of the saw head must be set. The stroke is set by the collars (A & B) on the shaft (C). TO SET THE STROKE: Without powering the saw, cycle the head down by depressing the foot switch.
7.2C GUARD ADJUSTMENT (POWER DOWN FEED) SEE FIGURE 17 ON THE FOLLOWING PAGE. CAUTION: THE GUARD MUST BE ADJUSTED EVERY TIME THAT THE STROKE OF THE MACHINE IS ADJUSTED.

DO NOT USE BLADES DESIGNED FOR THIS MACHINE ON ANY OTHER EQUIPMENT. The CPO-350-NF saw is designed to use a maximum 13.5 inch (340mm) diameter blade.
7.2E POWER DOWN FEED TROUBLESHOOTING THE HEAD FEEDS DOWN FULL SPEED WITH THE FLOW CONTROL (D) TURNED OFF. Bad check valve (V): Clean or replace it. THE HEAD FEEDS FAST WITH NO CONTROL, HEAD BANGING UP, LOW OIL LEVEL. Add oil (hydraulic oil). THE HEAD STOPS AND DOES NOT FEED THROUGH THE MATERIAL.
7.3 MATERIAL SUPPLY TRACKS A ten foot roller supply track, that can be bolted to the input side of the saw to support longer pieces of material, is an available option for this saw. The supply tracks can also be bolted end to end, to supply longer tracks, if needed.
7.4 DISCHARGE TRACKS WITH SCALES Roller discharge tracks equipped with either a right or left hand quick-loc are available in two lengths: 60" and 120" (122 & 303 CM). The discharge tracks mount to the machine in place of the 30 inch (76 CM) stop that was provided with the machine.
7.5 SPECIAL VISE JAWS Special vise jaws for holding square tubing, rectangular tubing and angle iron are stock items. 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. 7.6 LOCK-OUT DISCONNECT SWITCH A lock-out disconnect switch is available for this machine if your plant is not equipped with lock out capabilities.
8.0 TROUBLE SHOOTING GUIDE 8.1 ELECTRICAL TROUBLE SHOOTING 1. THE MOTOR WILL NOT RUN. Some models have a lock-out switch in the base of the saw. If your saw has this option, make sure that it is in the ON position. On manual and power vise machines, the Hi-Low switch must be in either the HI or the LOW position for the trigger switch to work.
8.2 BREAKAGE OR EXCESSIVE DULLING OF BLADES Select the proper blade and spindle speed for the material being cut. For recommendations, REFER TO SECTION 6.3. Always break in the blade before you start normal cutting. New blades have a very sharp edge.
8.3 COOLANT SYSTEM IF COOLANT WILL NOT FLOW: 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. Check the level of the coolant in the reservoir.
