Table inserts are installed on the turntable. When shipping the tool from the factory, the
table inserts are so fixed that the saw blade does not contact them. The burr of the
bottom surface of the workpiece is remarkably reduced, if the table insert is fixed so that
the gap between the side surface of the table insert and the saw blade will be minimum.
Before using the tool, eliminate this gap in accordance with the following procedure.
(1) Right angle cutting
Loosen the three 5 mm machine screws, then secure the left side table insert and
temporarily tighten the 5 mm machine screws of both ends. Then fix a workpiece
(about 7-7/8" (200 mm) wide) with the vise assembly and cut it off. After aligning
the cutting surface with the edge of the table insert, securely tighten the 5 mm
machine screws of both ends. Remove the workpiece and securely tighten the 5
mm center machine screw. Adjust the right hand table insert in the same way.
(2) Left and right bevel angle cutting
Adjust the table insert in the manner shown in Fig. 8-b and Fig. 8-c following the
same procedure for right angle cutting.
CAUTION:
2. Checking the saw blade lower limit position
Check that the saw blade can be lowered 23/64" to 7/16" (9 mm to 11 mm) below the
table insert as shown in Fig. 9-a.
When you replace a saw blade with a new one, adjust the lower limit position so that
the saw blade will not cut the turntable or complete cutting cannot be done.
To adjust the lower limit position of the saw blade, follow the procedure (1) indicated
below. (Fig. 9-b)
Furthermore, when changing the position of a 8 mm depth adjustment bolt that serves
as a lower limit position stopper of the saw blade.
