14. Press down 1R306 “Ring Spring Removing Jig” with the arbor press in order to lower the spring holder, while holding the blade case section firmly, so that it does not tilt or wobble.

15. Slowly lessen the pressure to 1R306 “Ring Spring Removing Jig”, while holding the blade case section firmly, so that it does not tilt or wobble.

16. Remove the spring holder and compression spring 27 from the blade case, when the jig gets free from the force of the compression spring.

1. Take the reverse step of removing, while paying attention to the following matters.

A. Scrape off the scratched portion of rod 16 with a file before mounting. Mount rod 16 from the side of the hex socket head bolt M6x10.

B. When pulling out the two screwdrivers in the final step, press the blade case section down to the lowest possible position. At the same time, the spring holder is mounted to the original position automatically.

C. Apply adhesive to the hex socket button head screw M6 with which the link plate is secured to the arm complete.

1. Loosen hex flange head bolt M8x12. Remove socket head flange screw M6 with a hex wrench, inserted through the punched hole of the safety cover. Now the safety cover section can be separated from the blade case.

2. The safety cover section can be disassembled by unscrewing pan head screw M5x12. Note: There is no need to remove the socket head flange screw M6 from the center cover for easy reassembling.

1. If you disassembled as per the instructions, the tapping screw bind PT3x8 has to be removed from the safety cover before reassembling.

2. Drive tapping screw bind PT3x8 again, after mounting torsion spring 36, center cover and center plate.

1. Remove the carbon brushes. Then, remove the table from the blade case section.

2. Remove lever 54 and the support plate.

3. After removing four M6x60 pan head screws, the motor section can be separated from the blade case.

Note: Compression spring 9 for the shaft lock falls off easily from the machine when separating the motor section from the blade case. Be careful not to lose this spring.

1. Put the shaft lock into the notch of the motor housing, then mount the armature to the motor housing.

2. While pushing the shaft lock in the direction designated by the black arrow, mount the motor section to the blade case in order to avoid pinching the shaft lock between the motor housing and blade case.

3. Take the reverse step of disassembling after the above process.

1. Lock the blade case section at the highest possible position with the stopper pin.

2. Remove the lock lever by unscrewing 2 M4x10 pan head screws. The lock lever can then be removed from the lock pin.

3. Remove the motor section as shown in the “Disassembling motor section” instructions when removing lock pin 8.

1. Pass lock pin 8 through torsion spring 9, and hold its tail with the switch box.

2. While sliding the lock lever to the switch button side, preliminarily tighten the lock lever with one M4x10 pan head screw.

3. Nip the hooked tail of torsion spring 9 and put it on the lock lever.

4. Adjust the position of the lock lever so that the distance between the lock lever and the safety cover is approx. 1mm. Then, finally tighten the lock lever with 2 M4x10 pan head screws.

1. Remove grip 32. From the bottom side of the base, unscrew the pan head screw M5x12. Now the knock spring can be removed.

2. After removing the guide fence, lever up the kerf board with a screwdriver to remove it.

1. Mount the turn base and flat washer 8, and tighten the hex lock nut M8x13 with socket wrench 13. The hex lock nut M8x13 has to be tightened so that the turn base can move without wobbling.

2. Take the reverse step of disassembling after the above process.

1. Adjusting to 90° to turn base:

While applying 1R208 “90-degree Set Square”, turn Hex bolt M8x28 on the motor housing side until both the saw blade and turn base contact the jig closely.

2. Adjusting to 45° to turn base:

While applying 1R209 “45-degree Set Square”, turn Hex bolt M8x28 on the saw blade side until both the saw blade and turn base contact the jig closely.

1. Set the bevel angle to 90°.

2. Provisionally tighten M8x30 hex bolt (B) into the smaller screw hole on the left side of the guide fence (when viewed from the operator’s position).

3. While checking the angle of the guide rule to the saw blade using a 90 Degrees set square (No. 1R208), pivot the guide fence by moving its right end until the angle is 90 degrees.

4. After completion of the squaring adjustment, securely tighten the four M8x30 hex bolts; first A and D, then B and C.

The handle cover cannot be separated from the switch box without removing the lock lever of the safety lock mechanism. First, remove the lock lever as instructed in the “Disassembling safety block mechanism” section.

1. Remove the handle cover. Now the relay can be replaced.

2. When assembling the switch section, do not forget to mount the clamp plate and felt ring 6. Also, do not remove the sponge sheet from the handle cover when mounting it to the switch box. These three parts protect the machine against sawdust.

– The lead wire of the soft start circuit has to be held with the lead holder.

– Do not push the insulated connector into the motor housing through the punched hole.

The lead wires which are put on the edge of the field have to be bundled with varnish tetron tubes by separating them into two groups. A maximum of four lead wires can be in each bundle.

– Before securing the clamp plate, put the lead wires between rib A and B.

– When a line filter is used (exclusively for low voltage in Great Britain), pass the following lead wires through the line filter:

– Field lead wire (orange)

– Soft start lead wire (Purple)

– Put the line filter in the space illustrated.

– Put the lead wires connected to the relay through the punched hole, between the boss and rib A.

– When putting lead wires onto the relay, do not put them on this area.

– Be careful not to pinch the lead wires of the light circuit between rib B and the relay, when a fluorescent job light is installed.

– Put the insulated connectors into the space between the relay and the inner wall, or push them into the punched hole.

– Put the noise suppressor into the space between the relay and the inner wall, or push it into the punched hole when it is used.

– Put lead wires in the lead holder.

– Put the insulated terminal in the space shown in the illustration.
