Turn it counterclockwise to reduce speed.
Setup & Operation Power Feed Operation 2 DANGER! Make sure the carriage fwd/rev switch is in the neutral position before turning the key switch to the on or ACC position. This prevents unintended carriage movement. Using The Power Feed HINT: To get a straight cut in the first part of the board, feed the blade into the log at a slow speed. This stops the blade from flexing and dipping up or down. Turn the carriage feed rate switch to a slow speed until the whole width of the blade has entered the cut.
Setup & Operation 2 Cutting The Log 2.15 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 turn the key switch to the ACC position. 2. Determine where to make your first cut. The sight gauge and the blade height scale will help you to do this (See Section 2.17 and See Section 2.18). Set the blade to the desired height with the up/down switch.
Setup & Operation Edging 2 2.16 Edging The following steps guide you through edging boards on the Wood-Mizer sawmill. 1. Raise the side supports to 1/2 the height of the flitches, or the boards that need to be edged. 2. Stack the flitches on edge against the side supports. 3. Clamp the flitches against the side supports halfway up the flitch height. (Wider flitches should be placed to the clamp side.
Setup & Operation 2 Blade Height Sight Gauge 2.17 Blade Height Sight Gauge See Figure 2-16. The sight gauge is provided on the cutting head carriage to help you decide where to make the first cuts on a log. SM0047 Sight gauge eye-level with bottom of blade FIG. 2-16 Move the carriage forward until the blade is close to the end of the log. Position yourself so that your eyes are level with the bottom of the sight gauge spring.
Setup & Operation Blade Height Scale 2 2.18 Blade Height Scale See Figure 2-17. The blade height scale is attached to the carriage head frame. It includes: a blade height indicator an inch scale a quarter scale Blade Height Indicator 6 Quarter Scale 5 14 4 8 15 6 5 4 16 4 8 5 17 6 4 18 5 8 Inch Scale 4 6 3H0007 FIG. 2-17 Rev C7-D2: The indicator is attached to the frame and moves up and down with the carriage head.
Setup & Operation 2 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. Example: You want to cut 1" (25 mm) random width boards from a log. Use the sight gauge to position the blade for the first cut. Move the carriage to an even measurement on the inch scale. Make a trim cut.
Setup & Operation Blade Height Scale 2 The Quarter Scale See Table 2-2. Two quarter scales are provided with four sets of marks. Each set represents a specific lumber thickness. Saw kerf and shrinkage allowance are included, but actual board thickness will vary slightly depending on blade thickness and tooth set. To choose which scale to use, determine what finished thickness you want to end up with. The Grade Hardwood Quarter Scale provides thicker finished boards usually required by commercial buyers.
Setup & Operation 2 Water Lube Operation 2.19 Water Lube Operation See Figure 2-18. The Water Lube System keeps the blade clean. Water flows from a 5-gallon (18.9 liter) bottle through a hose to the blade guide where the blade enters the log. A valve in the bottle cap controls the amount of water flow. FIG. 2-18 Not all types of wood require the use of the Water Lube System. When it is needed, use just enough water to keep the blade clean.

Sawmill Alignment Pre-Alignment Procedures 5 SECTION 5 SAWMILL ALIGNMENT 5.1 Pre-Alignment Procedures The Wood-Mizer sawmill is factory aligned. Periodically check the sawmill alignment and adjust if necessary. This chapter explains how to align the entire sawmill. Care should be taken in performing these steps. Sawmill alignment determines the accuracy and squareness of your cuts. The sawmill alignment steps are: 1. Ready the sawmill for alignment 2. Adjust the main bed rails parallel to the blade 3.
Sawmill Alignment 5 Frame Setup 5.2 Frame Setup Stationary sawmills should be setup on firm, level ground before proceeding with alignment. Shim the feet so the weight of the sawmill is evenly supported. Portable sawmills should also be setup on firm, level ground. Adjust the two middle outriggers on the main frame tube down just enough to lift weight from the trailer tire. Adjust the two outer outriggers down just so they touch the ground but do not bear weight.
Sawmill Alignment Blade Installation And Alignment 5.3 5 Blade Installation And Alignment See Figure 5-1. Install a blade and apply the appropriate tension (See Section 2.5 Tensioning The Blade). Blade tension is adjusted with the tension handle shown. 1/8" (3.0 m) ± 1/32" (0.75 mm) 1 1/4" Blade 3/16" (4.5 mm) ± 1/32" (0.75 mm) 1 1/2" Blade SM0044C FIG. 5-1 Check the vertical alignment of the blade wheels.
Sawmill Alignment 5 Blade Installation And Alignment To adjust where the blade travels on the idle-side blade wheel, use the cant control shown in Figure 5-1. 1. Start the engine. Pull lightly on the clutch handle to rotate the blade until it locates itself on the blade wheels. If the blade is too far forward on the wheels, turn the cant control counterclockwise. If it is too far back on the wheels, turn the cant control clockwise. 2.
Sawmill Alignment Saw Head Slide Pad Adjustment 5.4 5 Saw Head Slide Pad Adjustment There are eight nylon pads positioned between the saw head frame and vertical mast. The spacing of the pads is factory set and rarely needs adjusting. To check the pad spacing, perform the following steps. NOTE: The pads on the engine side of the mast are referred to as the "inner" pads. The pads on the control side of the mast are referred to as the "outer" pads.
Sawmill Alignment 5 Saw Head Slide Pad Adjustment FIG. 5-3 5. Loosen the lower locking bolts and turn the adjusting bolt as necessary to provide the pad spacing described in Step 4. CAUTION! Due to variations in the vertical mast, the pad spacing may vary throughout the travel of the saw head. Check the pad spacing at the top and bottom ends of the mast only. Pads adjusted too tight will cause premature up/down motor failure.
Sawmill Alignment Adjusting The Lower Track Rollers 5.5 5 Adjusting The Lower Track Rollers Making these adjustments correctly will give you square cuts and accurate dimensions across the width of your boards. 1. Move the saw carriage so the blade is over the rear main bed rail. See Figure 5-4. 2. Check that both lower track rollers are touching the inside of the rail. The stop-blocks should be within 1/16-1/8" (1.5-3.0 mm) of the rail. 3.
Sawmill Alignment 5 Adjusting The Lower Track Rollers 5. Repeat this step with the blade over the front main bed rail. 6. Move the carriage from the front of the mill to the back. Watch the lower rollers and stop blocks. Make sure the gap between the rail and both stop-blocks never goes over the 1/16-1/8" (1.5-3.0 mm) tolerance. 7. Repeat, running the head from the back to the front of the mill. Make adjustments as needed.
Sawmill Alignment Adjusting Main Bed Rails To Blade 5.6 5 Adjusting Main Bed Rails To Blade 1. Move the clamp all the way out to flip the clamp down if neccesary. Adjust the clamp until it is positioned under the outer blade guide. 2. Move the saw head until the blade is centered over the clamp. 3. Raise the saw head until the blade measures 14 1/2" (360 mm) from the top of the clamp. Use a rule to determine the actual distance of the blade to the clamp. See Figure 5-6. FIG. 5-6 4.

Measure the distance between the bottom of the blade and the bed rail at each end of the bed rail. The bed rail should measure 15" (375 mm) (+1/32 [0.75 mm] -0) from the blade at both ends of the rail. 6.
Sawmill Alignment Blade Guide Arm Vertical Adjustment 5.7 5 Blade Guide Arm Vertical Adjustment 1. Move the saw head so that the blade guide arm is directly over a bed rail. 2. Adjust the blade guide arm out to within 1/2" (15 mm) of full open. 3. Put a block of wood between the bed rail and the arm. Lower the carriage so that the arm just rests on the block. See Figure 5-8. Turn outside rollers to raise or lower end of blade guide arm SM0065B FIG. 5-8 4.
Sawmill Alignment 5 Blade Guide Arm Horizontal Adjustment 5.8 Blade Guide Arm Horizontal Adjustment 1. Put the blade guide assembly back in the arm (if you took it out). Put the assembly back so that the flanged collar on the roller is about 1/8" (3.0 mm) from the back of the blade when the throat is 1/2" (15 mm) from full open. 2. Close the throat to within 1/2" (15 mm) from fully closed. Check to see that the flange is the same distance from the back of the blade. See Figure 5-9.
Sawmill Alignment Blade Guide Arm Horizontal Adjustment 5 See Figure 5-10. Adjustment Nuts Adjustment Nuts SM0066 FIG. 5-10 4. Adjusting the outside two rollers (furthest from the arm motor) inward will cause the flange to move away from the blade. 5. Adjusting the two outside rollers outward will cause the flange to move toward the blade. 6. Adjust until the roller flange is the same distance from the back of the blade in the open and closed position.
Sawmill Alignment 5 Aligning The Blade Guides 5.9 Aligning The Blade Guides Each Wood-Mizer sawmill has two blade guide assemblies that help the blade maintain a straight cut. The two blade guide assemblies are positioned on the saw head to guide the blade on each side of the material being cut. One blade guide assembly is mounted in a stationary position on the drive side of the saw head. This assembly is referred to as the "inner" blade guide assembly.
Sawmill Alignment Blade Deflection 5 5.10 Blade Deflection Perform the following steps to achieve proper blade deflection with the blade guides. 1. Raise the carriage until the blade is 15" (375 mm) above a bed rail. Measure the actual distance with a tape from the top of the rail to the bottom of the blade. 2. Install the blade guides. Make sure the two set screws shown are threaded into the blade guide shaft until they touch each other. See Figure 5-11.
Sawmill Alignment 5 Blade Guide Vertical Tilt Adjustment 5.11 Blade Guide Vertical Tilt Adjustment Check that the blade guide does not tilt the blade up or down. A Blade Guide Alignment Tool (BGAT) is provided to help you measure the vertical tilt of the blade. 1. Open the adjustable blade guide arm 1/2" (15 mm) from full open. 2. Clamp the alignment tool on the blade. Position the tool close to a blade guide roller. Be sure the tool does not rest on a tooth or burr, and is lying flat on the blade.
Sawmill Alignment Blade Guide Vertical Tilt Adjustment 5 See Figure 5-13. Loosen jam nuts and turn screws to tilt roller up or down SM0070 FIG. 5-13 8. Move the carriage forward so the back end of the tool is over the bed rail. 9. Use the set screws shown to adjust the blade guide tilt until the measurement from the bed rail to the tool equals the other two measurements taken. 10. Move the tool close to the other blade guide and repeat the previous steps.
Sawmill Alignment 5 Blade Guide Spacing 5.12 Blade Guide Spacing HINT: When adjusting blade guide spacing, loosen the top set screw and one side set screw only. This will insure horizontal and vertical tilt adjustments are maintained when the set screws are retightened. 1. Adjust the inner blade guide so the blade guide flange is approximately 1/16" (1.5 mm) from the back of the blade. 2. Loosen one side and one top set screw shown. Tap the blade guide forward or backward until properly positioned.
Sawmill Alignment Horizontal Tilt Adjustment 5 5.13 Horizontal Tilt Adjustment 1. Finally, both blade guides must be tilted horizontally. Adjust the blade guide arm half way in. See Figure 5-15. FIG. 5-15 2. Place Blade Guide Alignment Tool against the face of the outer blade guide roller. 3. Center the tool on the roller and measure between the back edge of the blade and the ruler at the end closest to the inner blade guide ("B"). 4.
Sawmill Alignment 5 Horizontal Adjustment Of Side Supports 5.14 Horizontal Adjustment Of Side Supports The side supports are used to clamp flats on a log to set the squareness of the next cut. The cut will only be as square as the supports. 1. Swing the side support down. 2. Measure between the face of the support and the main bed tube. Make measurements at both ends of the side support to make sure that it is parallel to the rail. See Figure 5-16. 3.
Sawmill Alignment Vertical Adjustment Of Side Supports 5 5.15 Vertical Adjustment Of Side Supports 1. Place a flat board across the bed rails. 2. Swing a side support up so that it is vertical. 3. Pull back at the top of the support to eliminate slack as if a log were being clamped against it. See Figure 5-17. 4. Check the angle of each support with a square on the board. 5. The side support should be 90° to the bed rails or leaning forward 1/32" (0.8 mm).
Sawmill Alignment 5 Clamp Stop Adjustment 5.16 Clamp Stop Adjustment 1. Once the side supports are aligned, pivot them down to their horizontal position. 2. Tie a string across the face of the side supports. See Figure 5-18. 3. Loosen the clamp stop bolts and adjust the clamp stop until it touches the string. FIG.
Sawmill Alignment Aligning The Pivot Bed Rails 5 5.17 Aligning The Pivot Bed Rails The two pivot bed rails are used when long cants are cut. (Long cants will often bend down at the ends.) The pivot bed rails need to be adjusted to the same level as the main bed rails. To adjust the pivot bed rails: 1. Adjust the pivot rail 90° to the main bed tube. 2. With the saw head raised so the blade is 14 3/4" from the main bed rails, move the saw head so that the blade is over one of the pivot bed rails. 3.
Sawmill Alignment 5 Aligning The Pivot Bed Rails 7. Adjust as needed until the pivot rail measures the same distance (±1/32) from the blade in the 45°, 90°, and -45° positions. CAUTION! Do not roll logs or large cants onto pivot bed rails.
Sawmill Alignment Sight Gauge Adjustment 5 5.18 Sight Gauge Adjustment After adjustments to the bed rails and blade guides are complete, adjust the sight gauge so that it accurately shows the position of the blade over the bed rails. 1. Move the saw head so the sight gauge is positioned over a bed rail. 2. Measure from the bed rail to the top of the sight gauge spring. 3. Loosen the nuts securing the sight gauge and adjust until the top of the spring is the same distance from the bed rail as the blade. 4.
Sawmill Alignment 5 Saw Head Tilt 5.19 Saw Head Tilt As the blade enters a wide log or cant, the outside of the saw head will drop down slightly. To compensate for the drop, use the lower track roller horizontal bolts to raise the outside of the saw head 1/16". 1. Move the saw head so the blade is positioned 14 3/4" (375 mm) above a bed rail. 2. Adjust the lower track roller horizontal bolts until the blade measures 14 13/16" (376.5 mm) from the bed rail near the outer blade guide. See Figure 5-20. FIG.
Sawmill Alignment Blade Height Scale Adjustment 5 5.20 Blade Height Scale Adjustment After the entire sawmill has been aligned and all adjustments made, check that the blade height scale indicates the true distance from the blade to the bed rails. 1. Move the saw head so the blade is positioned 14 3/4" (375 mm) above the bed rails by actual measurement with a rule. See Figure 5-21. 2. View the blade height scale with eyes level with the indicator.
