1.0 INTRODUCTION The CPO-350 Cold Saw is designed to cut solids, tubes, flats and other profiles in grades of material that range from hot and cold rolled steel, annealed tool steels, stainless, 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.
This machine is top heavy and must be anchored to the floor via the holes in the saw base. 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...

On machines equipped with either a power vise or a power down feed, the air supply must also be disconnected and locked or tagged. Scotchman offers a lock-out switch for this machine as an option, if your plant is not equipped with lock-out capabilities. If you are interested in this option, REFER TO SECTION 7.14 or contact your local dealer or the factory.
4.6 FRL USE AND MAINTENANCE SEE FIGURE 4 ON THE NEXT PAGE CAUTION: SHUT OFF AIR SUPPLY BEFORE SERVICING THE FRL The FRL (Filter Regulator Lubricator) is an important and often overlooked item on a cold saw. It helps to keep moisture from contaminating the pneumatic system and adds a little oil to keep the system lubricated.
Page 19
Scotchman Air Line Then pull water trap free. Filter Lubricant is recommended can be removed by squeezing the Qt.
4.7 GUARD ADJUSTMENT SEE FIGURE 5 BELOW. FOR GUARD ADJUSTMENT PROCEDURES ON SAWS EQUIPPED WITH THE POWER DOWN FEED OPTION, REFER TO SECTION 7.8. The proper adjustment of the blade guard on this machine is crucial to the operation of the machine and the safety of the operator.
4.8 COOLANT SYSTEM The coolant reservoir has a capacity of eight (8) gallons (30.3 liters). One gallon of coolant is shipped with the saw. For normal cutting, it should be mixed in a ratio of one part coolant to seven parts water. In conditions of heavier cutting, the ratio of water should be reduced to five parts.
5.2 CUTTING OILS AND LUBRICANTS SECTION 10.8 lists Scotchman’s parts numbers for cutting oils and lubricants. Using high quality lubricants and oils will greatly increase the life of this equipment. We recommend using only pure, synthetic, water soluble cutting oil for coolant. For the saw head, use a non-EP additive ISO-460 gear oil specified for worm gears.
5.4 COOLANT PUMP MAINTENANCE IF YOUR COOLANT PUMP IS LEAKING OR LACKS POWER, USE THE FOLLOWING STEPS. We recommend replacing the pump seal kit anytime that the pump is dismantled. FOR PART NUMBER IDENTIFICATION, REFER TO SECTION 9.6. Make sure that the power to the machine is off. Remove the four bolts (J) and remove the pump from the machine.
6.0 MACHINE OPERATION 6.1 INSTALLING THE BLADE - MANUAL MACHINES SEE FIGURE 8 BELOW. FOR INSTALLING BLADES ON MACHINES EQUIPPED WITH THE POWER DOWN FEED OPTION, REFER TO SECTION 7.9. Remove Knob (A) & Spread Open Lower Guard To Access Saw Blade FIGURE 8 Page 24...
Page 26
DO NOT MODIFY ANY BLADE TO FIT THIS MACHINE. DO NOT USE BLADES DESIGNED FOR THIS MACHINE ON ANY OTHER EQUIPMENT. The CPO-350 saw is designed to use a maximum 14 inch (350mm) diameter blade. The arbor size is 40mm with four 12mm pins spaced at 64mm.
6.2 SAW CAPACITIES Figure 9 below is a chart showing the maximum capacities of this machine in various materials at the most common angles from 0 degrees to 90 degrees. CPO - 350 #060331 03/21 90° 45° CAPACITIES WITH MAXIMUM DIAMETER BLADES 350 MM INCHES...
Selecting the proper blade speed is very important. The CPO-350 LT and HT saws have an RPM range from 22 - 44 (LT) and 44 - 88 (HT). The heavier the material, the lower RPM is best. The lighter the material, the higher RPM is best.
All models of the CPO-350, except those fitted with the power down feed option, have this down stroke or cutting depth adjustment. SEE FIGURE 11 ON THE FOLLOWING PAGE. This adjustment is used to keep the saw blade from cutting into the vise spindle and must be adjusted when changing sizes of materials or blades.

6.5 MITER LOCKING DEVICE SEE FIGURE 12 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. It is not recommended as a retro-fit in the field. The power vise allows automatic clamping of the material, which improves productivity and reduces operator fatigue.
Page 34
TO ADJUST THE VISE TO THE SIZE OF MATERIAL BEING CUT: Release the locking collar (D) on the vise spindle (see below). The vise spindle is left hand threaded and the locking collar must be turned clockwise to release it. Open the vise, using the positioning handles (E), and place the material in the vise.
7.3 REPLACING THE SPINDLE IN THE POWER VISE SEE FIGURE 14 BELOW. CAUTION: DISCONNECT THE MACHINE’S POWER AND AIR SUPPLY Disconnect the air lines (A). The air connections on the cylinder are snap connectors. To release the air connections, push the collar around the hose into the fitting and pull the hose out. To reconnect the lines, simply push the air line into the fitting as far as it will easily go.
7.4 REPLACING THE SEALS IN THE POWER VISE SEE FIGURE 15 BELOW. CAUTION: DISCONNECT THE MACHINE’S POWER AND AIR SUPPLY SEAL KIT IS P/N 076371 - Contains two small and two large o-rings and an oil seal. Locations below. Open the vise to its full open position. Disconnect the air lines from the cylinder (A).
7.5 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 will not retrofit to machines with serial number 11940491 and prior in the field. This option can be used on machines with or without the power vise option.
7.7 STROKE CONTROL ADJUSTMENT (POWER DOWN FEED) SEE FIGURE 17 ON THE FOLLOWING PAGE. Before powering the machine, the up and down strokes of the saw head must be set. The stroke is set by the collars (A & B) on the shaft (C). TO SET THE STROKE: The saw blade control switch for the saw blade is located in the electrical box on top of the motor.
7.8 GUARD ADJUSTMENT (POWER DOWN FEED) SEE FIGURE 18 ON THE FOLLOWING PAGE. CAUTION: THE GUARD MUST BE ADJUSTED EVERY TIME THAT THE STROKE OF THE MACHINE IS ADJUSTED. TO ADJUST THE GUARD: Before adjusting the guard, set the up and down stroke of the machine by following the instructions in SECTION 7.7.
BLADES DESIGNED FOR THIS MACHINE ON ANY OTHER EQUIPMENT. The CPO-350 saw is designed to use a maximum 14 inch (350mm) diameter blade. The arbor size is 40mm with four 12mm pins spaced at 64mm, also known as 4/12/64 pin spacing.
