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. 6, 7)
1. Hold the saw firmly and loosen (clockwise) the depth adjustment knob (D) and
move shoe to obtain the desired depth of cut.
2. Make sure the depth adjustment knob 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 7. 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.

Bevel Angle Adjustment (Fig. 7)
The full range of the bevel adjustment is from 0° to 50°. The quadrant is graduated in
increments of 1°. On the front of the saw is a bevel angle adjustment mechanism (Fig. 7)
consisting of a calibrated quadrant and a bevel adjustment knob (J).
TO SET THE SAW FOR A BEVEL CUT
1. Loosen (counterclockwise) the bevel adjustment knob (J) and tilt shoe to the
desired angle by aligning the pointer with the desired angle mark.
2. Retighten knob firmly (clockwise).
Shoe Adjustment for 90°Cuts (Fig. 8)
IF ADDITIONAL ADJUSTMENT IS NEEDED:
1. Adjust the saw to 0° bevel.
