These include push sticks, feather boards, filler
pieces, fixtures, jigs and any other appropriate
device that can be utilized to keep operator's
hands away from the blade. Upon completion of
the operation requiring removal of the guard, the
entire guard assembly must be placed back on
the machine in its proper working order.
Never use a dado head in a
tilted position. Never operate the saw without
the blade guard, splitter and anti-kickback
pawls for operations where they can be
used.
Safety Devices
Feather Board
The feather board (Figure 36) should be made
of straight grain hardwood approximately 1" thick
and 4" to 8" wide depending on the size of the
machine. The length is developed in accordance
with intended use. Feather boards can be
fastened to the table or rip fence by use of
C-clamps. Alternatively, drilled and tapped holes
in the table top allow the use of wing nuts and
washers as a method of clamping. If this method
of fastening is used, provide slots in the feather
board for adjustment. (The illustration shows a
method of attaching and use of the feather
board as a vertical comb. The horizontal
application is essentially the same except that
the attachment is to the table top.)
Push Stick & Push Block
The use of a push block or push stick provides
an added level of safety for the operator.
See the templates in Figures 38 and 39 for
construction details, or purchase one from the
JET Woodworking Machinery and Accessories
catalog.

Filler Piece
A filler piece (Figure 37) is necessary for narrow
ripping and permits the blade guard to remain on
the machine. It also provides space for the safe
use of a push stick.
