    Check that there is no sign of shipping damage to the electrical conduits, cords or hydraulic hoses. As supplied, the S20 Series III is built to run on three phase AC Voltage, as indicated on the machine serial plate and volt- age label.

  • Page 15: Hydraulic Oil

    CUTTING FLUID The S20 series III uses pump and reservoir to circulate necessary cutting fluid to the blade for maximum blade life. Your blade supplier will be able to provide information about cutting fluid products that are available for your needs.

  • Page 17: Section 2 - Operating Instructions

    SECTION 2 – 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 and Feed Rate setting are oper- ated from the control panel.

  • Page 18: Operator Panel Controls

    Operator Panel Controls SWITCH FUNCTION Pressing the red EMERGENCY STOP button will turn OFF all machine functions. EMERGENCY STOP To operate machine after emergency stop the EMERGENCY STOP knob has to be released. BUTTON To release EMERGENCY STOP turn knob clockwise. This switch has three positions: AUTO, OFF, and ON.

  • Page 19: Vise Control

    MECHANICAL CONTROLS VISE CONTROL The material clamping vise is a cam operated, double handle locking vise. The saw operator can push the vise handle to close the jaw on the material and then lock it from either side of the saw. The handles have two positions, forward toward the stock to unlock the vise and away from the stock to lock.

  • Page 20: Guide Arm Positioning

    GUIDE ARM POSITIONING The S20 Series III idler side guide arm is adjustable to accommodate varying material widths. The guide arm should be adjusted as close to the material as possible while still allowing it to pass. This process of matching the guide arm spacing to the material size is important to optimize blade life and ensure straightness of the cut.

  • Page 21: Blade Basics

    Variable pitch (following pages), bi-metal blades (like the ¾ or 4/6 bi-metal blade supplied with the Hyd-Mech machine) last much longer, cut faster and more accurately than the conventional carbon steel blades. In order to take advantage of the superiority of bi-metal blades, it is critical to properly “break in” a new blade. This is accomplished by taking two or three cuts through solid four or five-inch diameter mild steel at an extremely slow feed rate.

  • Page 22: Mist Coolant

    DETERMINE OPTIMUM BLADE PITCH – TEETH PER INCH (T.P.I.) Selecting a blade with proper tooth pitch is important in order to achieve optimal cutting rates and good blade life. For cutting narrow or thin wall structural materials, a fine blade with many teeth per inch (T.P.I.) is recom- mended.

  • Page 23: Work Stop

    WORK STOP The work stop is used to set a consistent cut length from 0 to 34 inches. 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 80 degrees end for end, and inserted for longer lengths.

    9. With the blade in place, turn the tensioner handle clockwise until Bade Tension Display shows required value. Recommended blade tension is 250 - 350 kg. If blade is under tensioned the blade motor will not start 0. Replace the blade cover and close wheels door. .

  • Page 28: Blade Guide Adjustment

    Drive Wheel Adjustment The Drive Wheel adjustment is closely linked to adjustment of the Idler Wheel. The purpose of the adjustment is to ensure that the back of the blade remains about .040-.080” away from the wheel flange during rotation. .

  • Page 29: Carbide Replacement

    CARBIDE REPLACEMENT The blade guide blocks are equipped with one top carbide and two side carbide inserts each. The working life of carbide guides is practically the same as that of the machine itself. However, if required they can be replaced by removing the plate fixing screw as shown.
  • Page 30 4. If the blade touches the square at the bottom loosen the top fixing screw “A” and tighten screws “B” the same amount until the square edge contacts the blade uniformly along the whole blade width. If contact is at the top of the square, loosen the bottom fixing screw “A”...
  • Page 31 As shown, there are two springs on socket head screws holding the brush assembly against the blade. There is also an adjusting stop socket set screw A with a hex nut C on it. This adjusting set screw works as a stop determining the brush position in respect to the blade.

  • Page 32: 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 de- scended to the bottom of its travel. The Head is adjusted so that the blade will descend slightly past the level of the table wear strip.

  • Page 33: 90 And 30 Degree Stop Adjustment

    GEARBOX LUBRICATION The machine is equiped with a worm gear which is permanently lubricated and therefore manitenance free. The box has no filler cap, level checker and drain, as it already contains the correct quantity of synthetic oil, guaranteeing perpetual lubrication of the crown and worm gear.
