    Setup & Operation Loading, Turning, And Clamping Logs Loading, Turning, And Clamping Logs CAUTION! Be sure the pivot rails, turning arm, clamp, and toe boards are below bed level before loading a log onto the bed. Failure to do so may result in machine damage or cause misalignment.
  • Page 33 Setup & Operation Loading, Turning, And Clamping Logs To Turn Logs 1. Use cant hooks or the optional log turner to rotate the log on the sawmill bed. See Log Turner Manual. 2. Spin the log against the side supports until it is turned the way you want it for the first cut. If you want to turn the log more, do the following steps.
  • Page 34 Setup & Operation Loading, Turning, And Clamping Logs See Figure 2-7. FIG. 2-7 3. Make sure the side supports are positioned low enough for the blade to pass over them. If they are not, back the clamp off slightly and push the side supports down until they are positioned below the level of your first few cuts.

  • Page 35: Up/Down Operation

    Setup & Operation Up/Down Operation Up/Down Operation 1. Install a blade, if needed, and check for correct blade tension. (See Section 2.5). 2. Set the cutting head to the desired height. (The blade height scale shows the height of the blade above the bed rails.) See Figure 2-8.

  • Page 38 Setup & Operation Clutch/Brake Operation 4. To engage the blade, pull the lever down until it locks in the down position. This engages the drive mechanism, releases the blade brake, and increases the engine speed to full throttle. To disengage the blade, raise the clutch/brake lever to the up position. This disengages the drive belt, engages the blade brake, and returns the engine to idle.

  • Page 39: Feed Operation

    Setup & Operation Feed Operation 2.12 Feed Operation The feed system includes a hand crank to move the carriage forward or backward. The speed at which the carriage travels forward depends on how fast you turn the feed crank. The height of the feed crank is adjustable. There are two sets of mounting holes, one higher and one lower.
  • Page 40 Setup & Operation Feed Operation CAUTION! Be sure to stop the blade when returning the carriage. This will not only prevent the blade from being pulled off and ruined by a wood sliver, but also will increase the life of the blade. CAUTION! Do not use the blade guide arm knob to move the carriage head forward and backward.

  • Page 41: Cutting The Log

    Cutting The Log 2.13 Cutting The Log The following steps guide you through normal operation of the Wood-Mizer sawmill. 1. Once the log is placed where you want it and clamped firmly, position the blade close to the end of the log.

    Setup & Operation Blade Height Scale 2.15 Blade Height Scale See Figure 2-12. The blade height scale is attached to the carriage head frame. It includes: two blade height indicators an inch scale a quarter scale FIG. 2-12 The two indicators are plastic markers that move up and down with the cutting head. The lower indicator is used to read the inch scale, and the upper indicator is used to read the quarter scale.
  • Page 45 Setup & Operation Blade Height Scale The Inch Scale The horizontal red line on the blade height indicator shows how many inches the bottom of the blade is above the bed of the mill. If you know the height of your blade at each cut, you can determine the thickness of lumber you are sawing.
  • Page 46 Setup & Operation Blade Height Scale The Quarter Scale See Table 2-2. The quarter scale has four sets of marks. Each set represents a specific lumber thickness. Saw kerf and shrinkage allowance are included, but actual board thick- ness will vary slightly depending on blade thickness and tooth set. An optional Grade Hardwood Quarter Scale is also available.
