MOUNTING HOLES
See Figure 8.
The compound miter saw should be mounted to a firm
supporting surface such as a workbench, mounting board,
or leg stand. The saw base has eight mounting holes: four
large bolt holes (B) and four small screw holes (A). If using
bolts, they should be of sufficient length to accommodate
the saw base, lock washers, hex nuts, and the thickness of
the workbench or other mounting surface. Tighten all four
bolts or screws securely. Do not use screws if mounting to
a leg stand.
The hole pattern for mounting to a workbench is shown in
figure 8. Carefully check the workbench after mounting to
make sure that no movement can occur during use. If any
tipping, sliding, or walking is noted, secure the workbench
to the floor before operating.
