Kapex KS120 Miter Saw 

In order to calibrate the lasers, you will need to puncture the 

decal on the side of the saw. The 2.5mm adjustment screw 

openings are identified by the small circles on the decal. 

 

The 2.5 mm hex key is shipped with the saw and 

is located in the Styrofoam packing material. 

► 

The Tilt adjustment is used to ensure the lasers are 

pointing parallel to the sawblade, so they trace out the 
same line regardless whether the saw is raised or lowered. 

► 

The Yaw adjustment rotates the laser (as viewed from 

above the saw) so it remains parallel with the path of the 
saw cut (front-to-rear). 

► 

The lateral adjustment moves the laser toward or away 

from the saw cut (sawblade). 

1. 

Before beginning, remove the laser dust lens and clean 

it. To remove the lens, loosen the retaining screw, 
push in and down on the ribbed surface to release the 

locking tabs, and then slide the lens out of the saw. 

 

2. 

Wipe off any dust and debris from the lens with a soft 
cotton cloth, or rinse it with water and mild soap. 

3. 

Reinstall the lens before making adjustments to the 

lasers. 

 

4. 

Clamp a smooth piece of scrap wood to the saw and 

using the depth limit (see page 14), make a shallow 
kerf cut across the board.  

► 

This kerf cut will help you aim the lasers where the 

saw actually cuts. 

► 

You can use any wood that has a relatively smooth 

surface. The white melamine board shown below 
provides a good contrast between the board surface 

and the kerf cut. 

 

5. 

Turn on the laser. 

6. 

Begin by adjusting the yaw settings so both lasers are 

parallel with the saw cut. 

 

Make sure to remove the hex key from the screw 

before gauging your progress. The pressure of 

the hex key is enough to deflect the laser.  

7. 

Next, lower the sawblade down into the kerf (touching 
the wood) and temporarily adjust the lateral setting 

until the laser is against the edge of the kerf. 

8. 

Raise the saw back to the top, and adjust the tilt 
setting so the laser remains against the edge of the 

kerf (at the same position as the previous setp). 

9. 

Verify the tilt adjustment by raising and lowering the 
saw and check that the laser remains the same 

distance away from the kerf. 

10. 

Finally, adjust the lateral position to line up with the 

edge of the saw cut.  

 

It is a matter of your own personal preference as 

to whether the laser lines split the edge of the 

kerf, or if they remain just outside of the kerf. 
Adjust the lateral position that you prefer.
