CAUTION:
The silver ring 25.4 mm in outer diameter is
•
factory-installed onto the spindle. The black ring
25 mm in outer diameter is included as standard
equipment. Before mounting the blade onto the
spindle, always be sure that the correct ring for the
arbor hole of the blade you intend to use is
installed onto the spindle.

Adjusting riving knife

Fig.23
Before adjusting the riving knife, loosen the two levers
by turning counterclockwise and press the top table on
the right side nearby the riving knife to its lowered
position. Then secure the top table by firmly re-
tightening the two levers as shown in the figure.
There must be a clearance of about 4 - 5 mm between
the riving knife and the blade teeth. Adjust the riving
knife accordingly
counterclockwise with the hex socket wrench and
measuring the distance. Tighten the hex bolts securely,
and then check to see that the top blade guard works
smoothly before cutting.
Fig.24
The riving knife has been installed before shipment from
the factory so that the blade and riving knife are in a
straight line.
Fig.25
CAUTION:
If the blade and riving knife are not aligned
•
properly, a dangerous pinching condition may
result during operation. Make sure the riving knife
is positioned between both outer ends of the blade
teeth when viewing from the top. You could suffer
serious personal injury while using the tool without
a properly aligned riving knife. If they are not
aligned for any reasons, always have Makita
authorized service center repair it.
Don't remove the riving knife.

Installing and adjusting rip fence
Fig.26
1. Install the rip fence on the table so that the rip
fence holder engages with the guide rail. Tighten
the clamping screw (B) of the rip fence firmly
clockwise.
2. Loosen the clamping screw (A).
3. Slide the rip fence and secure it so that the far
end from you of the rip fence is aligned with the
point at which the front edge of saw blade just
appears from top surface of the workpiece. The
purpose of this adjustment is to reduce risk of
kick-back toward operator that cut piece from the
workpiece is pinched between the saw blade and
rip fence and finally pushed out toward operator.
The line 3 varies by thickness of workpiece or the
table level. Adjust the position of the rip fence
according to the thickness of the workpiece.
After adjusting the rip fence, tighten the clamping
screw (A) firmly.
Fig.27
NOTE:
There are four patterns to position the rip fence as
•
shown in the figure. Rip fence has two slits on its
sides, one slit with an elevated fringe nearby on
the same side and the other without it. Use the
surface of rip fence with this fringe facing the
workpiece only when cutting off into a piece of a
thin workpiece.
