OPERATION
TO MITER CUT / CROSS CUT
See Figures 24 - 25.
A cross cut is made by cutting across the grain of the
workpiece. A straight cross cut is made with the miter table
set at the 0° position. Miter cross cuts are made with the
miter table set at some angle other than zero.
Pull out the lock pin and lift saw arm to its full height.
Lift the miter lock lever, then depress and hold the detent
release button to release the miter table.
Rotate the control arm until the pointer aligns with the
desired angle on the miter scale.
Release the detent release button, then push the miter
lock lever down to secure the miter table.
NOTE: You can quickly locate 0°, 15°, 22-1/2°, 31.6°, and
45° left or right by releasing the detent release button as
you rotate the control arm. The control arm will seat itself
in one of the positive stop notches, located in the miter
table base.
Place the workpiece flat on the miter table with one edge
securely against the fence. If the board is warped, place
the convex side against the fence. If the concave edge
of a board is placed against the fence, the board could
collapse on the blade at the end of the cut, jamming the
blade. See Figures 39 - 40.
When cutting long pieces of lumber or molding, support
the opposite end of the stock with a roller stand or with
a work surface level with the saw table. See Figure 29.
Align cutting line on the workpiece with the edge of saw
blade or laser line.
Grasp the stock firmly with one hand and secure it against
the fence. Use the work clamp or a C-clamp to secure
the workpiece when possible.
Before turning on the saw, perform a dry run of the cut-
ting operation to make sure that no problems will occur
when the cut is made.
Grasp the saw handle firmly. Squeeze the switch trigger.
Allow several seconds for the blade to reach maximum
speed.
Slowly lower the blade into and through the workpiece.
Release the switch trigger and allow the saw blade to
stop rotating before raising the blade out of workpiece
and removing the workpiece from the miter table.
