SETUP
8.
Make sure the workpiece is supported
at all times while sawing.
Use a
roller stand (not provided) with
larger workpieces if necessary.
9.
To properly understand all safety
warnings, be familiar with the following
safety terms and equipment:
a. Featherboard – A block with
“fingers” that hold the workpiece
against the fence while sawing.
b. Through-sawing – A cut made
from one side of a board to the
opposite side, without stopping.
c. Ripcut or Ripping - A cut made parallel
to (along with) the grain of the wood.
d. Crosscut or Crosscutting -
A cut made perpendicular (at a 90° angle)
to the grain of the wood.
e. Push-stick – A narrow strip of wood or other
soft material with a notch cut into one end
and which is used to push short pieces
of material through saws.
It provides a
safe distance between the hands and the
cutting tool.
Must be narrower than the cut
width to prevent contact with the blade.
f. Freehand – Feeding a workpiece through
the saw without using a fence or guided
support to guide it.
NOT A SAFE METHOD.
g. Kerf – The gap made by the
saw in the workpiece.
h. Kickback – A sudden reaction to a pinched,
bound, or misaligned blade, causing
an uncontrolled workpiece to lift up and
out of the saw toward the operator.
i. Spreader – A metal plate that follows
the saw blade to keep the kerf (gap)
from closing on the saw blade.
Spreaders, except riving knives, must
be aligned to the blade after blade
adjustment to prevent binding.
j. Riving Knife – A spreader mounted
on the same mechanism as the
blade.
Generally more effective
than simple spreaders.
10. As noted previously,
Kickback
is a
sudden reaction to a pinched, bound, or
misaligned blade, causing an uncontrolled
workpiece to lift up and out of the saw toward
the operator.
Kickback is usually a result of tool
misuse and can be limited or avoided
by following the precautions below:
Fence must be completely
parallel to the saw blade.
Workpiece must be free from flaws
(such as loose knots) and from foreign
objects (such as nails and screws).
Support large workpieces along their
entire length.
Large workpieces tend
to bend, grabbing the blade.
Do not use a dull, pitch-covered,
or damaged blade.
Do not use fence as a guide
when crosscutting.
Do not ripcut a twisted or warped
workpiece, or workpiece without
straight edge to guide along fence.
Maintain control of the workpiece.
Do not allow the workpiece to rest against
the moving blade without holding onto it.
If the blade binds or a cut is interrupted, turn
off the power switch and hold the workpiece
still until the blade stops.
Correct the cause
of blade binding before proceeding.
Before continuing an unfinished cut, center
the blade in the pre-cut kerf and check
that the saw teeth are not engaged into
the workpiece before turning on the saw.
Push the wood stock past the
blade prior to release.
11. Check guards for proper operation with saw
disconnected from power before each use.
Do not disable any guard.
Do not operate
saw if any movable guard does not move
freely and close instantly.
Make sure any
movable guard does not touch the blade in
all angles, depths of cut, and positions.
12. Keep the guard in place while through-sawing.
Verify that the spreader lines up with
the blade to prevent binding.
13. Construct an appropriate Push Stick
out of wood according to the
guidelines on the following page.
