The maximum cutting dimensions in [ ] in Table 4 can be obtained by adjusting the lower limit position of the saw
blade as indicated in Fig. 2-2, also with an auxiliary board [of 20 mm (25/32") width].
(5) Compound cutting through use of
miter and bevel cutting functions
By turning the turn table to the left or right and inclining the saw blade section (head) to the left or right, the Model
C 12FSA is capable of compound cutting (bevel and miter, see Figs. 10, 11 and 12) of workpieces with the
maximum dimensions shown in Table 5.
(6) Fine surface finish on cuts
Constant-speed cutting is achieved by minimizing
revolution variation due to changes in load during
sawing by means of an electronic control, as in the
C 10FS.
As indicated in Fig. 13, revolution variation during
sawing is electronically held to a minimum, while
providing a higher rotation speed during sawing than in
the competitors'. With this considerably higher speed
during sawing (over the normal load range), the amount
of material cut per tooth is reduced to ensure a finer
quality finish on the cut surface. Uneven cut surfaces at
the start of sawing are caused by numerous runouts of
the saw blade due to revolution changes dependent on
load variation. In the models without electronic control,
run out of the saw blade increases in a particular
revolution range indicated in Fig. 14.
