7.2 Blade Elevation and Tilting Adjustment
To adjust the blade elevation :
Loosen the lock
knob (C) as shown in Fig. 29 and turn the elevation
hand wheel (D). When the desired height is
obtained, re-tighten the knob (C). The blade should
be raised 1/8” to 1/4” above the top surface of the
material being cut.
To adjust the blade tilting : L
oosen the lock
knob (B) and turn the hand wheel (A). When the
desired angle is obtained, re-tighten the knob (B).
Refer to Fig. 29.

7.3 Crosscutting
"Crosscutting" means cutting across the grain of
a natural wood workpiece. In other man-made
materials, such as MDF or plywood, crosscutting
means cutting across the width of the workpiece.
Crosscutting requires the use of the miter gauge to
position and guide the work. Place the work
against the miter gauge and advance both the
miter gauge and work toward the saw blade.
Start the cut slowly and hold the work firmly against
the miter gauge and the table. One of the rules in
running a saw is that you never hang onto or touch
a free piece of work. Hold the supported piece, not
the free piece that is cut off. The feed in
crosscutting continues until the work is cut in two,
then the miter gauge and work are pulled back to
the starting point. Before pulling the work back, it is
good practice to give the work a little sideways shift
to move the work slightly away from the saw blade.
Never pick up any short length of free work from
the table while the saw is running. A smart operator
never touches a cut-off piece unless it is at least a
foot long. Never use the fence as a cut-off gauge
when crosscutting. Never use the miter gauge in
combination with the rip fence.
7.4 Ripping
"Ripping" means cutting with the grain of a natural
wood workpiece. In other man-made materials
such as MDF or plywood, ripping simply means
cutting lengthwise.
The rip fence is used to position and guide the
work. One edge of the work rides against the rip
fence while the flat side of the board rests on the
table. Since the work is pushed along the fence, it
must have a straight edge and make solid contact
with the table. The saw guard must be used. The
guard has a splitter to prevent the saw kerf from
closing.
Start the motor and advance the work holding it
down and against the fence. Never, stand in the
line of the saw cut when ripping. Hold the work with
both hands and push it along the fence and into the
saw blade..
Alternately, the feed can continue to the end of the
table, after which the work is lifted and brought
back along the outside edge of the fence. The
waste stock remains on the table and is not
touched with the hands until the saw is stopped
unless it is a large piece allowing safe removal.
