3. BLADE TWISTING (MISALIGNMENT IN CUT)
A. Pushing harder to cut through a knot, a nail or a hard grain area
can cause the blade to twist.
B. Trying to turn the saw in the cut (trying to get back on the
marked line) can cause blade twist.
C. Overreaching or operating the saw with poor body control (out
of balance), can result in twisting the blade.
D. Changing hand grip or body position while cutting can result in
blade twist.
E. Backing up the saw to clear blade can lead to twist.
4. MATERIALS THAT REQUIRE EXTRA ATTENTION
A. Wet lumber
B. Green lumber (material freshly cut or not kiln dried)
C. Pressure treated lumber (material treated with preservatives or
anti-rot chemicals)
5. USE OF DULL OR DIRTY BLADES
Dull blades cause increased loading of the saw. To compensate,
an operator will usually push harder which further loads the unit
and promotes twisting of the blade in the kerf. Worn blades may
also have insufficient body clearance which increases the chance
of binding and increased loading.
6. LIFTING THE SAW WHEN MAKING A BEVEL CUT
Bevel cuts require special operator attention to proper cutting
techniques – especially guidance of the saw. Both blade angle to
the shoe and greater blade surface in the material increase the
chance for binding and misalignment (twist) to occur.
7. RESTARTING A CUT WITH THE BLADE TEETH JAMMED
AGAINST THE MATERIAL
The saw should be brought up to full operating speed before
starting a cut or restarting a cut after the unit has been stopped
with the blade in the kerf. Failure to do so can cause stalling and
kickback.
Any other conditions which could result in pinching, binding, twisting,
or misalignment of the blade could cause kickback. Refer to the
sections Further Safety Instructions for All Saws and Blades
for procedures and techniques that will minimize the occurrence of
kickback.
Cutting Depth Adjustment (Fig. 1, 7, 8)
1. Hold the saw firmly and loosen (clockwise) the depth adjustment lever
(D) and move shoe (E, Fig. 1) to obtain the desired depth of cut.
2. Make sure the depth adjustment lever has been retightened
(counterclockwise) before operating saw.
For the most efficient cutting action, set the depth adjustment so that
one-half tooth of the blade will project below the material to be cut.
This distance is from the tip of the tooth to the bottom of the gullet in
front of it. This keeps blade friction at a minimum, removes sawdust
from the cut, results in cooler, faster sawing and reduces the chance
of kickback. A method for checking for correct cutting depth is shown
in Figure 8. Lay a piece of the material you plan to cut along the side
of the blade, as shown, and observe how much tooth projects beyond
the material.
