SAFETY PRECAUTIONS The S-20/23 has been designed to give years of reliable service. It is essential that operators be alerted to the safe opera- tion of this saw, and the practices to avoid that could lead to injury. The following safety rules are at the minimum neces- sary for the safe installation, operation, and maintenance of the saw.
VISUAL INSPECTION Head - keep away from moving blade Vise - never load stock with the blade moving Head - watch for head descending to the table Pivot - check for head movement blockage Drive - secure pulley cover when running...
HYDRAULIC OIL The S-20/23 is supplied with ISO VG22 hydraulic oil. Substitutes must be of the same vis- cosity in order for the system to work properly.
In order to provide a safe operation as well as to prevent potential damage to the As supplied your new S-20/23 is set to run on three phase voltage or single phase. The supply voltage of the machine displayed on the Serial # Plate and the voltage label.
Wiring Connections for machines with VFD option L1, L2, L3, and ground terminals The power cable should be routed found inside of the box through the hole found at the bottom right of the box. A suitable strain relief should be used.
SECTION 2 – OPERATING INSTRUCTIONS The operator control panel provides the operator with all the controls necessary to operate the saw after the cutting angle has been set and the stock has been loaded and secured. All of the electrical functions and the Feed Rate setting are operated from the control panel.
ELECTRICAL CONTROLS (S20 VFD / S23 VFD OPTION) Blade Speed (1BS) – m/min). Adjustment should be made only when the blade is running. Coolant Switch (1SS) – ON: OFF: AUTO: Blade running. Blade Start (5PB) – A green push button. The blade will not start with the head in the down position, if any safety switch- es are not closed, or if the emergency stop is depressed.
ELECTRICAL CONTROLS (S20H VFD / S23H VFD OPTION) Coolant Switch (1SS) – ON: OFF: AUTO: Blade running. Blade Speed (1BS) – m/min). Adjustment should be made only when the blade is running. Blade Start (5PB) – A green push button. The blade will not start with the head in the down position, if any safety switch- es are not closed, or if the emergency stop is depressed.
BLADE BASICS Technology is rapidly changing all aspects of production machining. Metal cutoff is no exception. The advances price of high-technology blades. Variable pitch, bi-metal blades (like the 4/6 or ¾ bi-metal blade supplied with the machine) last much longer, cut faster and more accurately than conventional carbon steel blades. In order extremely slow feed rate.
OPTIMUM BLADE PITCH Teeth per inch (T.P.I.) Selecting a blade with a proper tooth pitch is important in order to achieve optimal cutting rates and good blade life. many teeth per inch is recommended. For wide materials a blade with a coarse pitch should be used.
BLADE SPEED SELECTION (not applicable to S-23) The blade speed of the S-20 can be changed between four different speeds. The speed is determined by the ratio of the pulleys that drive the V belt. The four pulley sets give the optional speeds of 90, 140, 220 and 310 ft/min.
CHANGING BELT POSITION To change the blade speed of the S-20 it is necessary to release the V belt tension and move the belt to another set of pulley grooves. The tension on the V belt is maintained by means of a toggle handle assembly that moves the motor.
SECTION 3 - MAINTENANCE & TROUBLESHOOTING Switch off before beginning work. The emergency switch, which is used to turn the hydraulics off, should not be the only means of shutting the power off before cleaning or performing maintenance to the machine. The main power disconnect should be switched off and locked.
Repeat this process until both wheels IDLER WHEEL ADJUSTMENT S-20 Line On the blade tensioner slide assembly, there are three 9/16” hex head bolts. Loosen the two bolts at the left end by ¼...
S-23 BLADE TENSION ASSEMBLY S-20 BLADE TENSION ASSEMBLY BLADE GUIDE ADJUSTMENT At the bottom of the guide arms are the carbide blade guide assemblies, the photo shows the carbide- locking handle. These assemblies will need to be adjusted occasionally as the carbide pads become worn.
BLADE BRUSH ADJUSTMENT The machine leaves the factory with the blade brush adjusted for maximum life of the brush. This setting places the ends of the blade brush wires so as to contact the blade at the bottom of the blade gullets. The plastic drive wheel that is driven by the drive wheel face should be held against the blade face with the minimum force that is necessary.
HEAD DOWN LIMIT SWITCH The head down limit switch operates to cut power to the blade motor and the coolant pump motor when the Head has descended to the bottom of its travel in the Manual mode. The Head is adjusted so that the blade will descend slightly past the level of the vise wear strips.
GEARBOX LUBRICATION S23 synthetic oil. This oil has an ISO Viscosity Grade of 320 that is optimum for ambient temperatures from 20-70 used, this be equivelent viscosity wise and of the synthetic type. The lubricant must also have the necessary EP and anti-foaming additives.
TROUBLE SHOOTING PROBLEM PROBLEM CAUSE Carbide guide adjustment incorrect (adjust). Feed rate excessive (reduce). 1 Cutting out of square vertically. Blade worn (replace). Guide arms too far apart. Blade pitch incorrect . Angle not set correctly (adjust). Stock not square in vise. (reset material) 2 Cutting out of square horizontally.
