  • Page 14: Blade Clearance

    BLADE CLEARANCE The blade clearance on the LM1010 was set at the factory to .004 in. on the ends of the blades with a .003 gap in the center of the machine. At this setting, your shear should provide satisfactory results over a broad range of materials and thickness.
  • Page 15 REPLACING/ROTATING BLADES The blades on the LM Series shears are four edged blades constructed of high carbon, high chromium tool steel. Top and bottom blades are interchangeable. Upon utilizing all four edges of you blades, you may return the blades to the factory for re-sharpening or to a qualified blade re-sharpener, such as a blade manufacturer.
  • Page 16 Reposition the hold down assembly. BACKGAUGE INFORMATION The LM1010 shear is fitted with a front operated powered back gauge as standard equipment. The gauge was installed and calibrated at the factory and shipped intact mounted on the shear. Inspect the gauge carefully to determine any possible movement or damage in transit.
  • Page 17 USING THE DRO BACKGAUGE To operate the backgauge: 1. Press and hold the “IN” button located on the control box to move backgauge in. 2. Press and hold the “OUT” button located on the control box to move backgauge out. NOTE: FORWARD AND REVERSE OVER-TRAVEL SWITCHES ARE INSTALLED TO PREVENT BACKGAUGE CRASHES.

  • Page 18: Hold Down Adjustment

  • Page 19 SHEET SUPPORT SYSTEM a. Single Stroke: When the foot pedal is activated, the sheet support will drop down and remain down until the cycle is complete and then return to the up position. b. Continuous Stroke: When the foot pedal is activated, the sheet support will drop down and stay down as long as the foot pedal is activated.

  • Page 20: Maintenance

    MAINTENANCE On a monthly basis, remove the top cover (11) of each side panel and grease the gib plates (9, 10, 15). This can be best accomplished by jogging the cutter head down to the extreme down-stroke position, thus exposing a majority of the gib surface. WARNING! MAKE SURE THE POWER TO THE MACHINE HAS BEEN TURN OFF WHEN APPLING LUBRICATES.
