B.Cutting through material supported at the outer ends only can cause kickback. As the material weakens it sags, closing down the kerf and pinching the blade.
C.Cutting off a cantilevered or overhanging piece of material from the bottom up in a vertical direction can cause kickback. The falling cut off piece can pinch the blade.
D.Cutting off long narrow strips (as in ripping) can cause kickback. The cut off strip can sag or twist closing the kerf and pinching the blade.
E.Snagging the lower guard on a surface below the material being cut momentarily reduces operator control. The saw can lift partially out of the cut increasing the chance of blade twist.
2.IMPROPER DEPTH OF CUT SETTING ON SAW
To make the most efficient cut, the blade should protrude only far enough to expose 1/2 of a tooth as shown in Figure 9. This allows the foot plate to support the blade and minimizes twisting and pinching in the material. Refer to Cutting Depth Adjustment.
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.
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 if it is not done carefully.
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
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 BEVEL CUTS
Bevel cuts require special operator attention to proper cutting techniques – especially guidance of the saw. Both blade angle to the foot plate 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 Additional Safety Instructions and Operation for procedures and techniques that will minimize the occurrence of kickback.
