- Check the alignment of the riving knife, fence and miter slot to the blade.
- Check the saw blade for cracks or missing teeth. Do not use a cracked or dull blade or one with missing teeth or improper set. Make sure the blade is securely locked on the arbor.
- Always use the riving knife, blade guard, push stick and other safety devices for all operations where they can be used.
- On operations such as dadoing or molding where the blade guard cannot be used, use feather boards, fixtures and other safety devices.
- Reinstall the riving knife and blade guard immediately after completing the operation that required their removal.
- Be sure the saw blade rotates clockwise when viewed from the motor side (left side) of the machine.
- Turn the power off and do not leave the machine until it comes to a complete stop.
- Start – Press the green start switch.
- Stop – Press the red switch to stop.
- Rip Sawing - work piece is fed with the grain into the saw blade
- Crosscutting - workpiece is fed cross grain into the saw blade
- Bevel Cut – the saw blade is tilted at an angle less than 90 degrees to the table top
- Dado Cutting – is cutting a wide groove into a workpiece or cutting a rabbet along the edge of a workpiece.
- Listed below are conditions, which can cause kickbacks:
- Confining the cutoff piece when crosscutting or ripping.
- Releasing the work piece before completing the operation or not pushing the work piece all the way past the saw blade.
- Not using the riving knife when ripping or not maintaining alignment of the riving knife with the saw blade.
- Using a dull saw blade.
- Not maintaining alignment of the rip fence so that it tends to angle toward rather than away from the saw blade front to back.
- Applying feed force when ripping to the cutoff (free) section of the work piece instead of the section between the saw blade and fence.
- Ripping wood that is twisted (not flat), or does not have a straight edge, or a twisted grain.
- Do not use the miter gauge and rip fence in the same operation unless provision is made by use of a facing board on the fence so as to allow the cutoff section of the workpiece to come free before the next cut is started.
- The front handwheel (B) controls the raising and lowering of the blade (blade height).
- The side handwheel (D) controls the blade tilt.
- The blade can be adjusted for a tilt between 90º (vertical or a setting of 0º on the scale) and 45º left tilt (D).
1. Loosen the lock knob (A) on the front handwheel (B).
2. Turn the handwheel (B) clockwise to raise and counterclockwise to lower the blade.
3. Tighten the lock knob (A).
Blade tilt adjustment
1. Loosen the lock knob (C) on the side handwheel (D).
2. Turn the handwheel (D) counterclockwise to adjust the saw blade down to 45º left tilt.
3. Turn clockwise to adjust the saw blade to maximum of 90º.
3. After selecting the position, tighten the lock knob (C).
Insert Adjustment: Adjust the setscrews in the insert with a 2.5mm hex wrench to ensure that the insert is stable and flush with the table top.
1. Operate miter gauge by loosening the lock knob (A) and turning the miter body (B) to the desired angle. To move gauge beyond index stops of 45 degree and 90 degree, flip down the stop (C).
2. Adjust index stops by turning one of three adjustment screws (D).
Riving Knife Adjustment - Lateral alignment: The saw blade and riving knife must be in line as close as possible with each other (lateral alignment) for the prevention of kickback. Upon initial blade guard and riving knife installation no further adjustment should be necessary. Alignment should be checked and adjusted, if required, after each blade change.
Check the alignment as follows:
1. Remove the blade guard and pawl.
2. Place a straightedge (A, Fig. 13) on the table so it rests against the blade (B, Fig 13) and riving knife (C, Fig. 13). Rotate the blade so the top of the blade tooth touches the straightedge. The saw blade and riving knife must be in line.
If adjustment is required:
3. Remove the table insert.
4. Loosen the lock handle (A, Fig. 14) and remove the riving knife, making a note as to which direction the riving knife needs to be moved to align it with the saw blade.
5. Use a 3mm hex wrench, make adjustments to any of the four set screws (D, Fig. 15) accessible through openings located in the corners of the floating clamp block (E, Fig. 15).
6. If necessary, repeat the above procedure.
1. Disconnect the saw from the power source.
2. Raise the blade guard up a way from the blade.
3. Choose a tooth on the far side of the blade (towards the rear) and position the tooth slightly above the table insert. Mark the tooth with a marker. Measure the distance from the side of the blade to the right T-slot edge using a combination square. Make sure to measure between the teeth not on the tooth.
4. Rotate the blade toward the front so that the marked tooth is just above the insert. Measure the distance from the side of the blade to the right T-slot edge. The two measurements should be the same.
5. If they are not the same, loosen four hex socket cap screws that hold the table to the base.
6. Make the needed adjustments and tighten the four hex socket cap screws firmly.
7. Check the alignment once again after tightening hardware.
Adjusting 45 degree and 90 degree Positive Stops
1. Disconnect saw from power source.
2. Raise the saw blade to its maximum height using the hand-wheel.
3. Set the blade at 90 degrees to the table by turning the blade tilting hand-wheel clockwise as far as it will go.
4. Place a combination square on the table against the blade and check to see that the blade is at a 90 degree angle to the table. Make sure square is not touching a blade tooth.
5. If blade is not at 90 degrees, open the motor cover door, loosen lock nut and turn adjusting stop screw on the front trunnion in, or out. The adjusting stop screw should stop against the front trunnion bracket when the blade is 90 degree to the table.
6. Tighten the lock nut.
7. Set the blade at 45 degrees to the table by turning the blade tilting hand-wheel counterclockwise as far as it will go. Place a combination square on the table against the blade. Make sure square is not touching a blade tooth.
8. If the blade is not 45 degrees, remove the raising and lowering handle. Loosen lock nut and turn adjusting stop screw on the front trunnion in, or out. The adjusting stop screw should stop against the front trunnion bracket when the blade is 45 degree to the table.
9. Check the accuracy of the pointer on the angle scale and adjust, if necessary.
Changing the Belt - Referring to Figure 21:
1. Disconnect the machine from the power source, unplug.
2. Lower the blade to its lowest point.
3. Loosen two hex cap bolts (A).
4. Take the tension off of the belt (B) by lifting up on the motor.
5. Remove the belt from the arbor and motor pulleys.
6. Replace and tension the belt. The weight of the motor should apply enough tension to the belt. Tighten the hex cap bolts (A).
7. Check the belt tension after the saw has been used for a few hours. Adjust as necessary.
