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 4 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 11 Page 23...
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 12 Page 24...
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 HOOD OPEN this screen appears and the hood is not open, there is a CYCLE STOPPED!! problem with the hood safety switch.
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.
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 19 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.

Page 48
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 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.
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 25 ON PAGE 35.
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 saw hood must be closed for the motor to run. The MOTOR CONTROL switch must be in the ON position to start the saw motor.
10.2 BREAKAGE OR EXCESSIVE DULLING OF BLADES Select the proper blade. 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 COOLANT SYSTEM 1. IF COOLANT WILL NOT FLOW: A. 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. B.
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.
