  • Page 17: Control Operations

    FEED FORCE PUSH-BUTTON The FEED FORCE switch is used ONLY for the hydraulic setup. Service personnel should contact the Hyd-Mech dealer for information and procedures. CYCLE START PUSH-BUTTON The Cycle start is a single cycle start push-button that allows the operator to set up the next cut with the stock to be cut. With the mode switch in Auto, pressing Cycle Start will close the vise to hold the material.
  • Page 18 BOTTOM ROW CONTROL FUSE The Control fuse is located in the fuse holder and is accessible by depressing the holder in and turning. The control fuse is used for protection of the control circuitry which operates at 120 volts. The fuse is rated for 5 Amps maximum at 250 volts. MODE SWITCH The MODE switch is a three position switch.

  • Page 19: Sequencer Operation Guide

    SEQUENCER OPERATION GUIDE The Hyd-Mech Sequencer controller provides automatic single cycle operation of the S-20P Series II or S- 23P. This single cycle operation consists of the closing of the vise when the Cycle Start push-button is pressed, and the start of the blade and Head descent when the Blade switch is turned to Start. When the cut is completed the Head returns to the Head Up limit position, the blade stops, and the vise opens.

  • Page 20: Blade Speed Indicator

    The running blade speed is displayed on the Sequencer display face in either the Manual or Automatic Mode. The units measurement is factory set in Surface Feet Per Minute or Metric. This setting can be changed by a skilled operator. Contact Hyd-Mech Saws for assistance with this change.

  • Page 21: Parameter Options

    With option 2 the Blade wheel circumference measured in feet, times a factor of ten (Example, for S-23P, 5 feet x 10 = 50 ), is entered into the program. This value is used to calculate and display the blade speed.

  • Page 22: Section 2B, Saw Cutting Controls

    SECTION 2B, SAW CUTTING CONTROLS This section has been prepared to give the operator the ability to set up the saw for most cutting situations. The saw is equipped with variable blade speed control and hydraulic feed control, as well as an extensive door chart to guide the operator to the correct setting of these controls.

  • Page 23: Hydraulic Feed Control

    HYDRAULIC FEED CONTROL The Hydraulic Feed Control is located adjacent to the drive wheel box. These controls allow independent control of Feed Force and Feed Rate. Feed Force Knob Used to set Feed Force Limit (counterclockwise rotation to increase and clockwise rotation to decrease). Fast Approach Lever Depress for fast head descent.

  • Page 24: Chart Example #1

    CHART EXAMPLE #1 We will use the parameters chart to set up the saw for cutting 8" (200mm) Diameter #1045 Carbon Steel. DETERMINE EFFECTIVE MATERIAL WIDTH - W ( inches ) or (mm) STEP 1, Effective material width, W (in.) for most common shapes of materials, is the widest solid part of the material to be in contact with blade during cutting.

  • Page 25: Step 3, Determine Optimum Blade Pitch

    STEP 3, 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.

  • Page 26: Step 5, Determine Feed Rate Setting

    The following table gives examples of the optimum blade speeds for different materials. MATERIALS OPTIMUM BLADE SPEED ft/min m/min 5" (125mm) Dia Solid Carbon Steel 12" (300mm) I-Beam 4" x 4" (100 x 100mm) Rec Tube, 1/4" (6mm) Wall350 4"(100) 400 Stainless Steel 2"...

  • Page 27: Additional Cutting Setup Examples

    Feed Rate, continued If the saw is fitted with a blade coarser than optimum (e.g.. 1.4/2.5 TPI) we can still use the graph, but we go to the 1.4/2.5 curve. As a result we find that the FEED RATE is decreased to 1.3 in/min (133mm/min) for this blade. If however, the machine is fitted with a finer than optimum blade (e.g.

  • Page 28: Section 2C, Mechanical Controls

    SECTION 2C, MECHANICAL CONTROLS HEAD SWING and BRAKE An integral function of the S-23P is the ability to make mitred cuts at angles between 90 and 45 . The Head swing of the S- 23P is easily changed to set a different cutting angle by first releasing the Angle Brake lever, and then manually moving the Head to the cutting angle desired.

  • Page 29: Coolant Flow

    - Coolant flows if the blade is running. Guide Arm and on the Fence. The S-23P bandsaw is equipped with two independently controlled coolant spouts that are capable of supplying a generous flow of coolant to the blade. The left guide arm supplies a flow of coolant that should flood the blade as it moves through the carbide pads into the material to be cut.

    SECTION 3, MAINTENANCE and TROUBLESHOOTING 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 as this will make it easier to grip the blade closer to both wheels. 2.

  • Page 33: 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 .195" to .210" (5mm to 5.3mm) from the face of the blade wheels.

  • Page 34: Blade Guide Adjustment

    BLADE BRUSH ADJUSTMENT The S-23P 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.

  • Page 35: Drive Belt Replacement

    DRIVE BELT REPLACEMENT The drive belt on the S-23P is a long life grooved belt. It should last for many of hours of operation and should rarely require replacement. See the BLADE DRIVE ASSEMBLY drawing on Pg 6.2. 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.

  • Page 36: Lubrication
