[3] DISASSEMBLING/ASSEMBLING
[3]- 1. Disassembling/Assembling Safety Lock Mechanism
Note: LS1214L for Europe, South Africa and China are equipped with the safety lock mechanism.
When disassembling/assembling, follow the procedures described below and on next page.
DISASSEMBLING
1) Remove two M4x10 Pan head screws, then remove Lock plate and Torsion spring 8 from Rod 8. (Fig. 3)
2) See Fig. 4. By removing two CT4x16 Tapping screws, Rod holder can be removed from Rod 8.
The assembly of Lock lever and Rod 8 can now be removed.

Note 1. Assemble Rod 8 to Lock lever so that the Stop ring installation side is placed on the Lock lever side. (Fig. 4)
Note 2. Assemble Lock plate and Torsion spring 8 to Rod 8 as illustrated in the top right of Fig. 5.
Hook one end of Torsion spring 8 in the notch of Rod holder, and the other on Lock plate.
Note 3. For smooth action of Lock pin, fasten Lock plate to Rod 8 so that the distances A and B are equal as illustrated
in the bottom right of Fig. 5.

[3]- 2. Removal/Installation of Blade Case and Compression Spring 34
REMOVAL
1) While holding the saw head at the lowest position, insert two Round bars for arbor (No.1R235) into the side holes on
the cylindrical portion of Blade case. (Fig. 6) The Round bars prevent the saw head from returning to the rest position
by keeping Compression spring 34 compressed.

2) After removing grip, disconnect the linkage Fig. 7
between Arm and Blade case by removing
Hex socket head bolt M6x20, Flat washer 6
Dust nozzle
and Ring 6 from Link plate.

Then separate the saw head unit (Blade case
and Motor housing) from Arm. (Fig. 8)
Pipe 16-113 can be easily removed by
using a round bar sized as follows:
diameter= approx. 15mm,
length= more than 110mm
Apply the bar to Pipe 16-113, then tap it.

INSTALLATION
Referring to Fig. 6 to 10, do the reverse of the removing steps as follows:
1) Set the saw head unit on arbor press, and press down Spring holder to compress Compression spring 34.
2) With the spring compressed, insert two Round bars (1R235) into the holes of Blade case.
3) Install the saw head unit on Arm, and insert Pipe 16-113 through Arm and Blade case.
Important: Do not remove the two Round bars in this step.
4) Secure Pipe 16-113 with Hex socket head bolt M6x10.
In this step, do not forget to fix Link plate on Arm with Hex socket head bolt M6x20,
and make sure that Arm and Blade case are connected with Link plate.
5) While holding the saw head unit at the lowest position, remove the two Round bars.

3) Remove Retaining ring S-14 from Spindle using Retaining ring Fig. 14
S and R pliers (No.1R269).
Note: You may find some difficulty in removal of Retaining
ring S-14. This is because the spiral bevel gear is being
pushed toward Retaining ring S-14 by the elastic force
of Rubber ring 20. (Fig. 14) In this case, set the gear
section in a vise as illustrated in Fig. 15, and press Spiral
(1)
bevel gear 35 to counterbalance the elastic force of Rubber
ring 20. Now Retaining ring S-14 will be removed easily
using the Retaining ring pliers.

The ring turns in the groove on Spindle smoothly if installed
correctly in place.
4) Install Ball bearing 608LLB on Spindle using arbor press. (Fig. 19)
Now assembling of the Gear section has been completed.
5) Install the assembled Gear section on Blade case by doing the reverse
of the disassembling steps.
[3]- 4. Disassembling/Assembling Base Section
DISASSEMBLING
1) Separate Guide fence from the Base section by removing four M8x30 Hex bolts.
And remove a pair of Kerf boards by removing four CT4x12 Tapping screws. (Fig. 20)
2) Separate Turn base from Base by removing Hex bolt M8x40 with 13mm socket wrench. (Fig. 21)

2) Tighten Hex bolt M8x40 with 13mm socket wrench. (Fig. 21)
Important: Be sure to tighten Hex bolt M8x40 so that Turn base can move smoothly without wobbling.
3) Install Kerf board onto Turn base. (Fig. 20)
Then, following the steps described below, install Guide fence while doing squaring adjustment;
See Fig. 23.
1. Provisionally tighten M8x30 hex bolt (C) into the smaller screw hole on the right side of Guide fence
viewed from operator's position.
2. While checking the angle of Guide rule to saw blade using 90 degree Set square (No.1R208), pivot Guide fence
by moving its left end until the angle is 90 degrees.
3. After completion of squaring adjustment, securely tighten four M8x30 Hex bolts; first A and D, then B and C.

[4] ADJUSTMENT
[4]- 1. Angle Adjustment of Saw Blade
CAUTION: Make sure that the machine is unplugged before adjusting saw blade.
For adjusting the miter angle of saw blade to 0 degree;
use 90 degree Set square (No.1R208) as illustrated in Fig. 23 on page 10.
For adjusting the bevel angle of saw blade to 0 degree;
use 90 degree Set square (No.1R208) as illustrated in Fig. 33.
For adjusting the bevel angle of saw blade to 45 degrees;
adjust the bevel angle of saw blade to 0 degree, then adjust to 45 degrees
using 45 degree Set square (No.1R207) as illustrated in Fig. 34.

If the lens is contaminated, clean up using swab or the like.

ADJUSTMENT
WARNING:
Special attention should be taken to adjust the position of laser line because you are required to do the adjustment
with the tool plugged. Never turn on the main switch for cutting operation when adjusting the laser line position.
Turn on the independent switch for laser light only.
Also never look into the laser beam. Direct laser beam may injure your eyes.
1) Remove Safety cover section as follows:
Fig. 48
*Remove Hex flange head bolt M8x12 that secures Center cover to
Blade case. (Fig. 48)
*Center cover can now pivot, and Flat head screw M5 is visible.
By unscrewing Flat head screw M5, Safety cover section can be
removed from Blade case. (Fig. 49)
Hex flange head
2) On Spindle, install Ring 16 (the one inside of the blade),
bolt M8x12
Spacer (No.1R349) and Laser beam positioning jig (No.1R315).
Then tighten Hex flange head bolt M10x20 with socket wrench.
(Fig. 50)
Center cover
Note:
No need for installing the following parts;
Safety cover
Outer flange, Ring 16 (the one outside of the blade), Inner flange
3) One of the two M4x6 Hex socket head bolts for positioning laser line is placed under Laser label. Therefore, remove or
peel off the label halfway until the bolt is entirely visible. (Fig. 50)
Important:
Before starting the adjustment, make sure that the attached Laser beam positioning jig is located at 90 degree angles
both to Guide fence and Base.

4) Plug in the tool, and turn on the independent switch for laser light. (Fig. 51)
5) Position Thumb screw M5x24 almost at the center of Top cover in order to allow for wide adjustment range. (Fig. 52)

6) As illustrated in Fig. 54, lower No.1R315, then turn the hex socket head screw of 118 so that the laser line is projected
in parallel with the reference line of No.1R315.
Note: In this step, the laser line never coincides with the reference line.

7) Raise No.1R315 as illustrated in Fig. 55, and turn the hex socket head screw of 124 so that the projected laser
line coincides with the reference line of No.1R315. Now the adjustment is finished.
If the laser line does not coincide with the reference line, adjust the screw so that the laser line is projected in parallel
with the reference line. Then adjust the position of Thumb screw M5x24 as illustrated in Fig. 56 so that the laser line
coincides with the reference line.

8) If the laser line still does not coincide with the reference line,
repeat the steps from 5) to 7).
9) After adjustment, be sure to install Laser label on the initial position
because the label also plays a role of dust seal. (Fig. 57)
