    SPECIFICATIONS and INSTALLATION Upon delivery of your new S-20 Series II saw, it is imperative that a thorough inspection be undertaken to check for any damage that could have been sustained during shipping. Special attention should be paid to the electrical and hydraulic systems to check for damaged cords, hoses and fluid leaks.

    Tank & Pump Coolant components (Shown with tank removed). HYDRAULIC OIL The S-20H option is supplied with Texaco Rando HD46 hydraulic oil. Substitutes should be a #46 hydraulic oil. The power pack and tank is mounted on the inside of the door found at the idler side of the infeed table.

  • Page 14: Power Wiring Connections

    POWER CABLE ROUTING The main power cable can be routed up through the bottom of the head frame to the access holes in the end of the control panel. Cable liquide tight reliefs should be used to secure the cable into the control panel to ensure there is no movement of the cable when the machine is operated.

    OPERATING INSTRUCTIONS OPERATOR CONTROL PANEL 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 are operated from the control panel.

  • Page 19: Blade Basics

    BLADE BASICS Technology is rapidly changing all aspects of production machining. Metal cutoff is no exception. The advances made in the bandsaw blade industry have definitely brought down the cost per cut, despite the three fold higher price of the newer technology blades. Variable pitch (following page), bi-metal blades (like the 3/4 or 4/6 bi- metal blade supplied with the machine) last much longer, cut faster, and more accurately than the conventional carbon steel blades.

  • Page 21: Blade Speed Selection

    BLADE SPEED SELECTION 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 APPROXIMATE BLADE SPEED 90, 140, 220, and 310 Surface Feet Per Minute.

  • Page 22: Guide Arm Positioning

    GUIDE ARM POSITIONING The S-20 guide arms are adjustable to accommodate varying material widths. The guide arms should be adjusted as close to the material width as possible while still allowing the material to pass between them. This process of matching the guide arm spacing to the material size is important to optimize blade life.

  • Page 23: Optional Controls

    OPTIONAL CONTROLS WORK STOP The work stop is used to set a consistent cut length from 0 to 40”. The photo shows the stop at a short length which is adjusted with one or both of the locking handles. The bar with the actual stop attached to it can be removed, turned 180 end for end, and inserted for longer lengths.

  • Page 27: Blade Changing Procedure

    BLADE CHANGING PROCEDURE NOTE: Wear gloves for protection from the sharp blade. 1. Open the Idler Wheel and Drive Wheel doors and swing the head to 45 as this will make it easier to grip the blade closer to both wheels. Loosen the Blade Tensioner by turning counter clockwise.

  • Page 28: Blade Tracking Adjustment

    BLADE CHANGING PROCEDURE, CONTINUED 9A. As the blade tracking will stay fairly constant, it should be checked occasionally as shown on the drive wheel tracking photo below. The blade teeth should protrude from .185" to .200" from the face of the blade wheels.

  • Page 29: Blade Brush Adjustment

    BLADE GUIDE ADJUSTMENT At the bottom of the guide arms are the carbide blade guide assemblies, the photo below shows the carbide locking handle. These assemblies will need to be adjusted occasionally as the carbide pads become worn. To adjust properly, follow this simple procedure. Loosen the hex nut on the locking handle with a 9/16 wrench and turn the handle clockwise until it rests against the coolant tap on the idler guide arm or the roll pin on the drive guide arm.

  • Page 30: Head Down Limit Switch

    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. The Head is adjusted so that the blade will descend slightly past the level of the vise wear strips.

  • Page 31: Lubrication

    S -20 Series II are primarily the saw pivot points which are equipped with grease fittings, and metal to metal surfaces that require lubrication to prevent wear and seizure. NOTE: Hyd-Mech recommends Monthly lubrication. Head horizontal pivot fitting. Swivel Pivot pin fitting under dome cap.

    TROUBLE SHOOTING GUIDE PROBLEM PROBLEM CAUSE 1. Cutting out of square vertically. - Carbide guide adjustment incorrect (adjust). - Feed rate excessive (reduce). - Blade worn (replace). - Guide arms too far apart. - Blade Pitch Incorrect . 2. Cutting out of square horizontally. - Angle not set correctly(adjust).
