10-6. Reassembly Requiring Adjustment

(1) Adjustment of squareness between the saw blade (dummy disc) and the fence
Square
Fig. 15
place a square so that it is flush against the side surface of the saw blade (or dummy disc), and move the
Fence [55] as necessary so that it is in an exact right angle with relation to the saw blade (or dummy disc).
Finally, tighten the two Hex. Socket Hd. Bolts M8 x 45 [54] to fix the Fence [55] in position.
*Dummy disc: A dummy disc is a toothless disc with the same external diameter as a saw blade, and is used
to perform accurate inspection and adjustments.
(2) Confirmation of saw blade height
The lower limit of the saw blade cutting depth is factory-adjusted so that when the saw blade is fully lowered,
its cutting edge is 28 to 30 mm (1-3/32" to 1-5/32") below the upper surface of the Table Insert [66]. Lower the
saw blade and confirm that it stops at the correct position.
(3) Adjustment of saw blade lower limit position
When adjusting the lower limit of the saw blade, be sure to use a saw blade with an external diameter of 255
mm. Failure to properly adjust the lower limit position of the saw blade may result in the following problems.
1 Inability to obtain the maximum cutting capacities of the machine
There is a danger that the saw blade may come in contact with and cut into the Table [64].

The lower limit of the saw blade cutting depth is adjusted at the factory so that when the saw blade is fully
lowered, its cutting edge is 28 mm to 30 mm (1-3/32" to 1-5/32") below the upper surface of the Table Insert
[66]. If this position is lower than the specified values, confirm without fail that it does not come in contact with
the Table [64]. If it is necessary to adjust the saw blade lower limit, loosen the Hex. Nut M6 [38] on the Hex.
Bolt M6 x 20 [37] and turn the Hex. Bolt M6 x 20 [37] if necessary. By turning the Hex. Bolt M6 x 20 [37]
clockwise, the saw blade lower limit is lowered. By turning the Hex. Bolt M6 x 20 [37] counterclockwise, the
saw blade lower limit is raised. On completion of adjustment, ensure that the Hex. Nut M6 [38] is properly
tightened.
[Caution]
Perform the adjustment carefully to ensure that the saw blade does not cut into the Table [64].

After disassembly/reassembly or replacement of the Base [59], the
Table [64], the Fence [55] or the Support [39], it is necessary to
check the squareness between the saw blade (or dummy disc) and
Fence
the Fence [55], and perform adjustment as necessary if they are not
at an exact right angle with relation to each other. Adjustment
procedure is as follows. First, position the saw blade (or dummy
Saw blade or

which houses the Table Insert [66]. Next, as illustrated in Fig. 15,
