Ryobi RTS21 Manuel D'utilisation page 37

If the blade is not an exact 45°:
 Unlock the bevel locking lever.
 Loosen the 45° adjustment screw.
 Place a combination square beside the blade on the
right. The edge of the square and the saw blade should
be parallel.
NOTE: Make sure that the square contacts the flat part
of the saw blade, not the blade teeth.
 Lock the bevel locking lever.
 Tighten the adjustment screw. Check again for
squareness and continue to adjust if needed.
 If needed, adjust the bevel indicator to 45°.
 Make a test cut.
The adjustment screws must be below the saw table surface
so the workpiece doesn't catch on uneven edges. If unable
to make this adjustment, take the product to an authorized
service center.
TO CHECK THE ALIGNMENT OF THE RIP FENCE
TO THE BLADE
See Figure 52.
The rip fence must be parallel to the saw blade and the miter
gauge grooves.
WARNING:
A misaligned rip fence can cause kickbacks and jams.
To reduce the risk of injury, always maintain proper rip
fence alignment.
 Unplug the saw.
 Raise the locking lever to permit the rip fence to be moved.
 Place a framing square beside the blade and move the
rip fence up to the square. Take the dimension on the rip
scale.
 Move the fence back and turn the framing square 180°
to check the other side.
 If the two dimensions are not the same, loosen the two
bolts on the fence and align it.
 Retighten the two bolts.
 Make two or three test cuts on scrap wood. If the cuts
are not true, repeat the process.
