The thickness of the riving knife is 1.8 mm for Models
5603R and 5703R or 2.0 mm for Models for 5903R
and 5103R or 2.5 mm for Model 5143R.
CAUTION:
• Do not use saw blades which do not comply with the
characteristics specified in these instructions.
• Do not use saw blades the disc of which is thicker or
the set of which is smaller than the thickness of the
riving knife.
To remove the saw blade, depress the shaft lock fully
to prevent shaft rotation, then use the hex wrench to
loosen the hex socket head bolt. (Fig. 1)
Now remove the outer flange, raise the safety cover
as much as possible, and remove the saw blade.
(Fig. 2)
Install the saw blade using the reverse of the removal
procedure. Install the inner flange, saw blade, outer
flange and hex socket head bolt, in that order. Be sure
to secure the hex socket head bolt tightly with the
shaft lock fully depressed. (Fig. 1 & 3)
CAUTION:
• Make sure that the blade teeth point forward in the
same direction as the tool rotation (the arrow on the
blade should point in the same direction as the
arrow on the tool).
• Never depress the shaft lock while the saw is
running.

Riving knife adjustment (Fig. 4)
Use the socket wrench to loosen the hex head socket
bolt for the riving knife adjustment, then raise the
safety cover. Move the riving knife up or down over
the two protuberances for settings indicated in the
illustration, so as to obtain the proper clearance
between the riving knife and saw blade.
CAUTION:
Ensure that the riving knife is adjusted such that:
The distance between the riving knife and the toothed
rim of the saw blade is not more than 5 mm.
The toothed rim does not extend more than 5 mm
beyond the lower edge of the riving knife.
Adjusting depth of cut (Fig. 5)
Loosen the lever on the depth guide and move the
base up or down. At a desired depth of cut, secure the
base by tightening the lever.
CAUTION:
• Use a shallow depth of cut when cutting thin work-
piece for cleaner, safer cuts.
• After adjusting the depth of cut, always tighten the
lever securely.
