CAUTION: USE ONLY HIGH SPEED STEEL BLADES DESIGNED FOR THIS MACHINE. DO NOT MODIFY ANY BLADE TO FIT THIS MACHINE. DO NOT USE BLADES DESIGNED FOR THIS MACHINE ON ANY OTHER EQUIPMENT. THE MAXIMUM RPM’S FOR THESE BLADES ARE 600 FOR THE 12-1/2" AND 700 FOR THE 10-3/4". The CPO-315-HFA saw is designed to use a maximum 12-1/2 inch (315mm) diameter blade.
Page 21
Adjust the blade guide bolts (G), if required. These guides are required only when the blade has a small amount of deflection in it or when a very exact cut is required. Adjust the inside, or right hand bolt, first. The bolt should be adjusted up to where it just touches the blade as close to the teeth as possible and lock the retaining nut.

The following are set-up and maintenance instructions for the material main vise. Make sure that the filter/lubricating device (A) is full of oil. NOTE: Use a quality (ISO 22) air line lubricant designed for automatic oilers. Slide the shuttle valve (F) on the filter/lubricator device down to the closed position. Connect the air supply to the shuttle valve.
6.5 SHUTTLE VISE & 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.

Set the shuttle vise indicator to the desired length by loosening the moving stop (M) and move it to the length desired on the scale and re-tighten it. These bolts must be locked down tight, to prevent the length setting from changing while the saw is in operation. Check them periodically throughout the day.
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 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.

10.0 TROUBLE SHOOTING GUIDE 10.1 ELECTRICAL TROUBLE SHOOTING 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.
Have your blades re-sharpened by someone who has the right equipment for circular cold saw blades. Improper re-sharpening is one of the most common problems encountered in cold sawing. Keep the blade flange, the face of the blade spindle and the blade clean and free from nicks. Any contamination or nicks on the flange, spindle or the blade will cause the blade to run out of alignment.
10.5 PLC TROUBLESHOOTING SEE FIGURE 18 ON THE FOLLOWING PAGE. The PLC on this machine has a readable screen on it that can be used to diagnose most problems that you may encounter with the machine. The main controller has 12 inputs numbered I-1 to I-12 and six outputs numbered Q-1 through Q-6.
