    LIFTING THE S20P WITH A FORK LIFT The S20P is shipped with a shipping pallet attached to the saw. When lifting the pallet with a forklift truck make sure that the load is firmly balanced. Minimum fork length of 72" (1827 mm) is recommended to safely lift the pallet. WRAPPED FOR SHIPPING The S20P is shrink-wrapped for shipping from our plant.

  • Page 17: Cutting Fluid

    CUTTING FLUID The S20P uses a pump and reservoir to circulate the necessary cutting fluid to the blade for maximum blade life. Your saw blade supplier will be able to provide information to the cutting fluid products that are available for your needs. No cutting fluid (coolant) is supplied with the machine.

    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 24: Coolant Flow

    COOLANT FLOW The S20P bandsaw is equipped with a coolant pump supplying coolant flow to four coolant outlets. • The wash gun is provided for clearing chip accumulations. • Guide arm coolant nozzles, one at each guide arm, are equipped with a flow control shut-off valve. The guide arm nozzles should be adjusted to apply an even covering of coolant to the blade.

  • Page 25: 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 26 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 recommended. For wide materials a blade with a coarse pitch should be used.

  • Page 27: Section 3 - Maintenance And Troubleshooting

    SECTION 3 – MAINTENANCE AND TROUBLESHOOTING SAFETY DURING MAINTENANCE AND TROUBLESHOOTING “Lock-out”, or “Lock-out Tag-out” are terms that refer to procedures taken to prevent the unexpected start-up, or other re- lease of energy, by a machine, whenever anyone is required to remove or bypass safety guards or devices, or whenever anyone is required to place part of his body in a hazard area.

  • Page 28: Blade Changing Procedure

    BLADE CHANGING PROCEDURE NOTE: Wear gloves for protection from the sharp blade. . Open the Wheels door by unscrewing the two knobs. 2. Loosen the Blade Tensioner by turning counter clockwise. 3. Open the blade guard at idler guide arm by undoing the mounting screws and removing it as illustrated below.
  • Page 29 4. Remove the worn blade by sliding it off the wheels and out off both guide blocks 5. Your new blade will be in a coil. While wearing gloves, hold the blade away from yourself; twist the blade to uncoil it.

  • Page 30: Blade Tracking Adjustment

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

  • Page 31: 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 32: 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.

    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 34: Angle Brake Adjustment

    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 35: Blade Tension Slide Adjustment

    BLADE TENSION SLIDE ADJUSTMENT To reduce the play, which may develop over time between the blade tensioner slide and slide gibs, adjust the screws be- tween the gibs and slide as follows: . Remove the head front cover. 2. Undo blade tension. 3.

  • Page 36: Lubrication

    LUBRICATION The S20P was designed to minimize the maintenance requirements. Moving assemblies and contact faces need lubrica- tion on a regular schedule whether they are in heavy use or not. The lubrication requirements of the S20P are primarily the saw pivot points which are equipped with grease fittings, and metal to metal surfaces that require lubrication to pre- vent wear and seizure.
