🛑 This page is a work in progress for the Wiki Overhaul project.


Purpose

The Mikita LS1219L sliding compound miter saw is used to make crosscuts only in wood and wood composite materials (e.g., plywood, MDF). Typical categories of crosscuts are listed below.

🛑 No metal shall be cut on this saw!


Terms

  • Cross Cut (Chop Cut): A “chop cut” is a crosscut made when the saw is held to the rearmost position and is operated like a conventional (non-sliding) miter saw. Using the chop cut method lowers the cross-cutting capacity; however, many users prefer using this method because it is quicker when making repeat cuts. This method can also produce more accurate cuts because the saw head is locked in the retracted position.
  • Slide Cut: A “slide cut” is made with the head assembly unlocked and able to move away from the fence. This movement is supported and precisely controlled by the axial glide system. The maximum cross-cutting capacity is utilized by using this method. A slide cut is best used for cross-cutting workpieces wider than can be done with a chop cut – pieces wider than 5-1/2" and up to a maximum width of 15" across. NEVER pull the saw toward you during a cut. The blade can suddenly climb up on top of the workpiece and force itself toward you.
  • Miter Cut: A “miter cut” is a crosscut made with the blade perpendicular to the horizontal table. The blade is not tilted, and the bevel pointers are both on the 0° lines. Miter cuts can be made at any angle across a workpiece within this saw’s range, up to 60° left and right.
  • Bevel Cut: A “bevel cut” is a crosscut made with the blade perpendicular to the fence and with the table set at 0° miter. The blade can be tilted to any angle within the saw’s 48° range.
  • Compound Cuts: A “compound cut” is a single crosscut made with the saw blade preset at two angles combining a miter angle (relative to the vertical fence) with a bevel angle (relative to the horizontal table). A compound cut can be made as a chop cut or a slide cut. Miter angles will be with the table rotated away from 0° and within the saw’s range. A bevel angle is when the blade is tilted away from 0°. This saw’s range is from right.
  • Groove Cuts: A groove cut should be made as a slide cut. The depth stop adjustment feature is used to limit blade depth of the saw bade when cutting the grooves. NOTE: For best results, Asmbly recommends using the table saw with an optional dado blade set for cutting grooves and non-through cuts.

Hazards

As with all machine tools, there are many hazards associated with their use and exposure to bystanders. Some of the hazards include, but are not limited to the following:

  • Amputation: The high speed and large diameter rotating saw blade poses significant a risk. Body parts must always be kept out of the path of the saw blade. Absolutely no adjustments shall be made to cutting angles (bevel or miter), fences, or stops until the saw has been turned off and the blade comes to a complete stop.
  • Puncture or Laceration: The sharpness of saw blade teeth pose a risk of injury during setup, handling, or saw blade replacement.
  • Kickback/Projectiles/Flying Objects: The high rate of speed at which the saw blade is rotating can cause kickback to the work piece. When this occurs, the saw may shift violently, cause the work piece to shift and/or break apart and splinter, and cause the offcut, dust and chips to become projectiles.
  • Other: The rotational direction of the saw blade is always pulling the work piece into the cut (this is referred to as a climb cut). This creates two direct hazards:
  1. You may be pulled into the saw blade cut.
  2. The saw blade may suddenly come out of the work piece and move towards you. You must maintain firm control of the saw head by utilizing the handle to prevent either of these from occurring.

Limitations

  • The compound sliding miter saw must only be used for cross cuts.
  • The width of the work piece is limited to:
  • No metal shall be cut.

Materials

Work piece material choices include wood, composite wood, and wood products.

Training

Required
Recommended
  • Successfully demonstrate knowledge and proficiency in the following Training Competencies:
    • Identify and describe all control, adjustments, and functions of the compound sliding miter saw.
    • Correctly setup and adjust the compound sliding miter saw for all types of cuts.
    • Demonstrate proper judgement in selecting clamping/securing work piece holding for the appropriate type of cuts.
    • Demonstrate knowledge and the ability to reset all compound sliding miter saw functions to square and perpendicular following each type of cut in preparation for the next user.

Personal Protective Equipment (PPE)

Required

  • Close-toed shoes
  • Eye protection

Recommended

  • Hearing protection
  • Avoiding gloves (to prevent potential snagging or entanglement of fingers)

Tool Safety Rules

  • Observe and follow all Asmbly Woodshop Rules.
  • Understand and follow the Makita’s manufacturer operating procedures.
  • Verify all saw blade guards are in place and adjusted correctly.
  • Never bypass a safety device.
  • Ensure that the dust collector is hooked up and functioning correctly before use.
  • Never leave the compound sliding miter saw unattended while it is running.
  • Clean the tool and surrounding area before (if necessary) and after use.
  • Ensure the surrounding area is free of tripping hazards before use.
  • Ensure the power is off before making any adjustments, changing the saw blade, or physically inspecting the saw blade.
  • Never feed the running saw blade into the work piece at rate faster than is safe for the material type or size.
  • Never make freehand cuts by raising the work piece into the saw blade.
  • Do attempt to work pieces that are too small to easily hold with your hands. Instead, use a clamping jig or fixture. If the work piece is shorter than 4 inches, consider using a different machine.
  • When in doubt, ask for assistance!
