Safety Devices - Powermatic 66 Instruction Manual & Parts List

The guard, splitter, and anti-kickback pawls supplied
with the saw should be used for all cutting opera-
tions where they can be used. When performing op-
erations where the guard can not be used, as in some
dadoing operations, alternative safety precautions
should be taken. These include push sticks, feather
boards, filler pieces, fixtures, jigs and any other ap-
propriate 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.
CAUTION: Never use a dado head in a
!
tilted position. Never operate the saw
without the guard, splitter and anti-
kickback pawls for operations where
they can be used.

Feather Board (Figure 35).
The feather board 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 es-
sentially the same except that the attachment is to
the table top.)
Filler Piece (Figure 36).
A filler piece is necessary for narrow ripping and per-
mits the guard to remain on the machine. It also
provides space for the safe use of a push stick.
Push Stick & Push Block (Figures 37 & 38).
These items help feed the workpiece along fence
and blade while keeping the operator's hands at a
safe distance from the blade.
