Grooves in the workpiece can be cut as indicated in Fig. 41 by adjusting the stop knob.
Cutting depth adjustment procedure:
(1) Turn the anchor plate on the direction shown in Fig. 42.
Lower the motor head, and turn the stop knob by hand. (Where the head of the stop
knob contacts the anchor plate.)
(2) Adjust to the desired cutting depth by setting the distance between the saw blade and
the surface of the turntable (see ⓑ in Fig. 42).
NOTE: When cutting a single groove at either end of the workpiece, remove the
unneeded portion with a chisel.
11. Cutting easily-deformed materials, such as aluminum sash
Materials such as aluminum sash can easily deform when tightened too much in a vise
assembly. This will cause ineffi cient cutting and possible overload of the motor.
When cutting such materials, use a wood plate to protect the workpiece as shown in
Fig. 43-a. Set the wood plate near the cutting section.
When cutting aluminum materials, coat the saw blade with cutting oil (non-combustible) to
achieve smooth cutting and a fi ne fi nish.
In addition, in case of a U-shaped workpiece, use the wood plate as shown in Fig. 43-b to
ensure stability in the lateral direction, and clamp it near the cutting section of the workpiece
and tighten it using both the vise assembly and the clamp available in the market.
