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.
5.1 CONTROL PANEL FUNCTIONS The following section gives a brief description of the touch screen and its functions. Before powering the machine, please familiarize yourself with the location and the function of each of these items. SECTION 7.0 will describe how to set the machine up for an operation. SEE FIGURE 3 BELOW.
5.1 A 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.
5.1 B EMERGENCY STOP SWITCH This switch stops the saw motor and allows the head to return to the up position. The emergency stop switch also applies the material vise air pressure. Once this switch has been used, the operator must restart the machine.
5.1F CUT PROFILES This is the CUT PROFILES MENU. Before performing any operation, you need to set up a cut profile operation. The only profiles that come with the machine are the general or metric profile. You can store up to 100 profiles. Press the recipe screen and name the profile. You can use any combination of numbers or letters that you want for each particular profile.
5.1G MANUAL OPERATION MENU This is the MANUAL OPERATION MENU. The manual operation mode is used to calibrate the stop, make sample cuts and set the stroke and other settings of the machine. All of the functions in the manual menu will function when the saw hood is open, except the START blade function, the head up and the head down buttons.
5.1H CUSTOMER CALIBRATION & SET-UP This is the CALIBRATION SCREEN. This screen is used to calibrate the length stop on the saw. Just follow the instructions on the screen to calibrate the stop. Set your stop 3 to 4 inches from the saw blade. The part count direction will either count parts up to your pre-set number on the counter or down from the pre-set number.
5.1I DESIRED LENGTH SCREEN This is the DESIRED LENGTH SCREEN. Any time you move the stop, this screen will open. Move the stop until the desired length appears on the screen. The stop has a fine adjustment knob on it that you can fine tune the length with when you are close to your desired length.
5.1J FACTORY SET-UP SCREEN This is the FACTORY SET-UP SCREEN. These settings are pre-set at the factory and should not need to be changed. The vise release setting chooses whether the vise opens when the blade is down or up. Having the vise release in the down position will speed up the cutting operation.
5.1K MODEL & SERIAL NUMBER MENU This is the MODEL AND SERIAL NUMBER MENU. You will need the information on the screen when contacting the manufacturer for replacement parts or troubleshooting assistance. FIGURE 10 Page 22...
5.1L MAINTENANCE MENU This is the MAINTENANCE MENU. The PLC menu is used for most troubleshooting problems. The VFD menu is used for the same. Each menu will be covered on the following pages. FIGURE 11 Page 23...
5.1N PLC MAINTENANCE SCREEN This is the PLC MAINTENANCE SCREEN. This screen can be used to diagnose most problems with the machine if a fault code does not appear on the screen. For example, if the machine won’t start an operation and you come to this screen and the saw head up light is not lit, this means that the saw head is either not all the way up or the proximity switch is bad or not properly aligned.
5.1O HOOD OPEN SCREEN This is the HEAD OPEN SCREEN. This just means that the cycle has been stopped because the hood is open. If this screen appears and the hood is not open, there is a problem with the hood safety switch. FIGURE 14 5.1P BATCH COMPLETE This is the BATCH COMPLETE SCREEN.
5.1Q FEED FAILURE SCREEN This is the FEED FAILURE SCREEN. If this screen pops up, you could have one of several problems. The infeed rate on your profile is set too slow and the cycle times out before the material reaches the stop. You can increase the feed rate in the profiles screen.
5.1S CUT FAIL SCREEN This is the CUT FAIL SCREEN. This means that the cut cycle timed out before the head reached the down position. You will need to increase the down feed rate or edit the material feed watchdog in the timer menu. FIGURE 18 5.1T ALARMS HISTORY MENU This is the ALARMS HISTORY MENU.
5.1U AUTO OPERATION MENU This is the AUTO OPERATION MENU. In order for the machine to operate in the auto mode, there must be a profile loaded. Make sure that you have the correct profile for the job you are running. There must be a value on the parts counter.
The CPO-315-RFA is designed to use a maximum 12-1/2 inch (315mm) diameter blade. 10-3/4 inch blades are also available for this machine. Special blades are available for certain applications. For further information, contact your dealer or the factory.
Page 32
FOR THESE BLADES ARE 600 FOR THE 12-1/2 INCH (315 MM) AND 700 FOR THE 10-3/4 INCH (275 MM). The CPO-315-RFA saw is designed to use a maximum 12-1/2 inch (315mm) diameter blade. The arbor size is 40mm with four 12mm pins spaced at 65mm.

6.4 MATERIAL MAIN VISE SEE FIGURE 23 BELOW. The following are set-up and maintenance instructions for the material main vise. 1. Make sure that the filter/lubricating device (A) is full of oil. Use a quality (ISO 22) air line lubricant designed for automatic oilers. 2.
Page 36
Adjust the air pressure regulator (C). 90 PSI (6.2 BAR) is the minimum operating pressure. 105 PSI (7.2 BAR) is the maximum. The vise is activated by the top proximity switch on the saw head. The lubricating device (A) should release one drop of oil every 5 to 10 cycles. On top of the lubricating device is a clear plastic dome with a small tube inside.
6.5 POWER DOWN FEED REFER TO FIGURE 25 BELOW. FIGURE 25 Page 36...
Page 38
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).
6.6 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 40
NOTE: HOOD AND BLADE GUARD ARE NOT SHOWN FOR CLARITY FIGURE 26 Page 39...
7.0 MACHINE AUTOMATIC OPERATION (SET-UP) Load the material on the supply table. Load one layer only; do not stack material on the supply table. Stacking material will cause the machine to load more than one part and the machine will fault out.
Page 42
Press the feed advance button and feed the material to the stop. You may have to press the rocker forward button if the rocker feed rollers are not in the correct position. Press the vise close button. Press the coolant start button and blade start button. Press the head down button and make a cut.
8.0 MAINTENANCE 8.1 LUBRICATION SEE FIGURE 29 BELOW. Grease the head pivot pin (C), the spindle shaft and the feed roller bearings (A) with a high pressure, high temperature bearing grease, 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 12.1 lists Scotchman.s parts numbers for cutting oils and lubricants. Using high quality lubricants and oils will greatly increase the life of this equipment. Use only pure, synthetic, water soluble, cutting oil for coolant. We recommend our P/N 075751 saw coolant.
Page 46
Remove the drain plug (A) from the head casting and allow the fluid to drain. Remove the motor from the head. Remove the four bolts (E) from the bearing retainer (F). Remove the worm shaft assembly (J). The worm shaft has a 10mm threaded hole in the end of it for a slide hammer.
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.
8.7 COOLANT PUMP MAINTENANCE (OPTIONAL FLOOD COOLANT) SEE FIGURE 32 ON THE FOLLOWING PAGE. IF YOUR COOLANT PUMP IS LEAKING OR LACKS POWER, USE THE FOLLOWING STEPS: NOTE: WE RECOMMEND REPLACING THE PUMP SEAL ANYTIME THE PUMP IS DISMANTLED. A SEAL KIT IS AVAILABLE. FOR PART IDENTIFICATION, SEE THE FOLLOWING PAGE Make sure that the power to the machine is off.
9.0 OPTIONAL EQUIPMENT 9.1 SPECIAL VISE JAWS Special vise jaws for holding thin wall round tubes and profiles are available on a made-to-order basis. For prices and delivery on special jaws, contact your local dealer or the factory. 9.2 OPTIONAL DISCHARGE LENGTHS There are optional ninety inch and one hundred and twenty (120) inch discharge assemblies available for this machine.
10.0 TROUBLE SHOOTING GUIDE 10.1 ELECTRICAL TROUBLE SHOOTING THE MOTOR WILL NOT RUN A. The main disconnect switch in the base cabinet must be on and the emergency stop switch must be pulled out. Also, check the supply voltage to the saw to make sure that it is the same as the motor voltage. If the supply voltage is correct and the switch energizes and the motor still will not run, contact your dealer or the factory.
10.2 BREAKAGE OR EXCESSIVE DULLING OF BLADES Select the proper blade and spindle speed for the material being cut. FOR RECOMMENDATIONS, REFER TO SECTION 6.1 Always break in the blade before you start normal cutting. Do not apply excessive down pressure on the workpiece. Excessive down pressure will cause the teeth to remove too large of a chip, resulting in premature dulling or breakage.
10.3 FLOOD COOLANT SYSTEM (OPTIONAL) IF THE COOLANT WILL NOT FLOW A. Make sure that the coolant switch on the control panel is on. Check the wiring connections to the pump and make sure that the pump is running. Check the level of the coolant in the reservoir. If there is less than three inches of coolant in the reservoir, the pump will not work.
10.4 PNEUMATIC SYSTEM REFER TO FIGURE 34 ON THE FOLLOWING PAGE. THE MOST COMMON PNEUMATIC/HYDRAULIC PROBLEMS ARE: Low levels of fluid in the reservoir: The fluid level in the power down feed reservoir should be approximately 2-1/2 inches below the top of the reservoir when the head is in the up position. CAUTION: THE AIR SUPPLY TO THE MACHINE MUST BE DISCONNECTED BEFORE YOU REMOVE THE FILLER PLUG FROM THE RESERVOIR.
