NOTICE indicates vital information.
WARNING! Clean sawdust from all areas where sawdust may
gather after every 8-hour shift. Failure to do so may result in fire,
causing death or serious injury.
SETUP SAFETY
WARNING! Do not use if the mill is set up on ground with more than a 10
degree incline. An incline could cause the mill to tip over.
Use a lifting device (fork lift, crane, etc.) for parts over 100 lbs.
Use two persons for lifting parts over 50lbs.1
Keep all non-essential personnel out of the area while setting
up the equipment.

2.2 Installation and Setup
WARNING! Use a lifting device (fork lift, crane, etc.) for parts
over 100 lbs.
Use two persons for lifting parts over 50lbs.1
1. Position the sawhead upward, out of the way.
2. Lower all log supports.
3. Move front pivoting bed rail parallel to the bed frame.
4. Position the SLR on the mill bed with the mounting brackets around the front and rear bed rails.
a. Position the shift handle at the front end of the mill.
b. Ensure the SLR frame is lying flat on the bed rails.
NOTICE: DO NOT tighten the clamp bolts on the bed rails. The SLR bed
must be able to move during operation. The clamp bolts should only be tight-
ened before towing the sawmill with the SLR attached.
5. Slide the SLR frame all the way over toward the inboard side of the sawmill bed until the SLR
stops touch the bed rail stop blocks.

NOTE: If not already done so, position the cams approximately 1.5 inches
away from the frame to prevent necessary realignment between lap siding
and shingle use.
3. Adjust the inner clamps as close to the SLR frame as possible to ensure the rear of the blocks
are positioned over the cams. See FIG. 4-3.
4. Clamp up to six shingle blocks, one over each cam. See FIG. 4-3.
5. Turn the clamp handle clockwise to firmly clamp the block in position to prevent movement during
operation.

6. Lower the shift handle.
7. Make a trim cut across all the blocks to even them out.
8. Calculate the desired shingle size:
Thick end - Thin end = Cut setting
Example:
For a shingle 1/8" at the thin end, and 5/8" at the thick end:
5/8" - 1/8" = 4/8" (1/2")
Set the block tilt for 1/2".
9. Raise the blade the calculated height.
10. Set the saw blade over a trimmed block.
11. Position the blade at the end of the first block.
NOTE: Double check the blade position. Measure from a downward pointing
sawtooth.
12. Adjust the shingle taper adjustment bolt in until it contacts the shift handle linkage.
13. Set the jam nut on the shingle taper adjustment bolt.

4.2 Shingle cutting operation
WARNING! Follow all safety and operating procedures stated in the operation
manual for your mill.
1. Lower the shift handle completely downward.
2. Make one trim cut to level all the blocks.
3. Lower the blade the thickness of the thin end of the shingle.
4. Raise the shift handle.
5. Make a cut and return the carriage.
Each shingle should match tapers to the setting you want. If they don't match,
repeat step 2 above.
6. Push the shift handle down and lower the blade the thickness of the thick end of the shingle.
7. Make a cut and return the carriage.
8. Repeat steps 3 - 7 down to the heart of the cants.
9. Unclamp the cants, flip 180°, and reclamp.
10. Continue sawing down as low as the SLR clamps will allow.

5-1 WM doc 9/10/20 Operation
SECTION 5 LAP SIDING OPERATION
5.1 Lap siding setup
To cut tapered siding, a single cant is clamped in the SLR. The siding taper adjustment bolts are
adjusted up so the lifting rollers tilt the SLR frame. When the shift handle is thrown, the SLR
frame tilts sideways.
NOTE: Maximum cant width is 12" (304.8 mm) and 12 ft long.
1. Install the SLR to the sawmill bed. See SECTION 2 Installation.
2. Adjust the shingle taper adjustment bolt to 1/4". See FIG.4-1, SECTION 4 Shingle Operation.
This will stop the shift handle when the lift rollers reach their maximum height.
3. Adjust the siding taper adjustment bolts all the way up so they do not lift the SLR frame from the
bed rails.
4. Adjust the inner clamp halves inside the shingle cams to avoid interference with the cant.
NOTE: To saw cants wider than 10", the cams must be adjusted out of the
way.
Be sure to mark each cam location so it can be returned to its original position

for sawing shingles.
Loosen the cam set screws and slide the cam along the shaft.
Reset the cams according toSECTION 4 Shingle Operation.
5. Position the cant so it is centered in the SLR frame.
6. Tighten the front clamp to secure one end of the cant.
7. Slide the outer clamp half in until it contacts the block.
8. Turn the clamp handle clockwise to firmly clamp the block in position.
9. Be sure the block is securely clamped so the block will not come loose while being cut.
