MACHINE USE
COMMON SAWING OPERATIONS
Common sawing operations include ripping and crosscutting plus a few other standard operations of a fundamental nature.
As with all power machines, there is a certain amount of hazard involved with the operation and use of the machine. Using
the machine with the respect and caution demanded as far as safety precautions are concerned, will considerably lessen the
possibility of personal injury. However, if normal safety precautions are overlooked or completely ignored, personal injury to
the operator can result. The following information describes the safe and proper method for performing the most common
sawing operations.
The use of attachments and accessories not recommended by Delta may result in the risk of injury to
the user or others.
CROSS-CUTTING
Cross-cutting requires the use of the miter gauge to
position and guide the work. Place the work against the
miter gauge and advance both the gauge and work toward
the saw blade, as shown in Fig. 46. The miter gauge may
be used in either table slot. When bevel cutting (blade tilted),
use the table groove that does not cause interference of
your hand or miter gauge with the saw blade guard.
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 the part of the workpiece
that will be cut off. Hold the supported piece, not the free
piece that is cut off. The feed in cross-cutting continues
until the work is cut in two, and 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. While blade is running,
never
touch a cut-off piece unless it is at least a foot long.
For added safety and convenience the miter gauge can be
fitted with an auxiliary wood-facing (C), as shown in
Fig. 47, that should be at least 1 inch higher than the
maximum depth of cut, and should extend out 12 inches or
more to one side or the other depending on which miter
gauge slot is being used. This auxiliary wood-facing (C) can
be fastened
to the front of the miter gauge by using two
wood screws (A) through the holes provided in the miter
gauge body and into the wood-facing.
When using the block (B) Fig. 48, as a cut-
off gauge, it is very important that the rear end of the block
be positioned so the work piece is clear of the block before
it enters the blade.
NEVER USE THE FENCE AS A CUT-OFF
gauge WHEN CROSS-CUTTING.
When cross-cutting a number of pieces to the same length,
a BLOCK OF WOOD (B), can be clamped to the fence and
used as a cut-off gauge as shown in Fig. 48. It is important
that this block of wood always be positioned in front of the
saw blade as shown. Once the cut-off length is determined,
secure the fence and use the miter gauge to feed the work
into the cut. This block of wood allows the cut-off piece to
move freely along the table surface without binding
between the fence and the saw blade, thereby lessening the
possibility of kickback and injury to the operator.
