Riving knife function
23. Use the appropriate saw blade for the riving
knife. For the riving knife to function, the body of
the blade must be thinner than the riving knife
and the cutting width of the blade must be wider
than the thickness of the riving knife.
24. Adjust the riving knife as described in this
instruction manual.
positioning and alignment can make the riving
knife ineffective in preventing kickback.
25. Always use the riving knife except when
plunge cutting. Riving knife must be replaced
after plunge
interference during plunge cutting and can create
kickback.
26. For the riving knife to work, it must be
engaged in the workpiece. The riving knife is
ineffective in preventing kickback during short
cuts.
27. Do not operate the saw if riving knife is bent.
Even a light interference can slow the closing rate
of a guard.
Additional safety warnings
28. Use extra caution when cutting damp wood,
pressure treated lumber, or wood containing
knots. Maintain smooth advancement of tool
without decrease in blade speed to avoid
overheating the blade tips.
29. Do not attempt to remove cut material when
blade is moving. Wait until blade stops before
grasping cut material.Blades coast after turn off.
30. Avoid Cutting Nails. Inspect for and remove
all nails from lumber before cutting.
31. Place the wider portion of the saw base on
that part of the workpiece which is solidly
supported, not on the section that will fall off
when the cut is made. As examples, Fig. 1
illustrates the RIGHT way to cut off the end of
a board, and Fig. 2 the WRONG way. If the
workpiece is short or small, clamp it down.
DO NOT TRY TO HOLD SHORT PIECES BY
HAND!

32. Before setting the tool down after completing
a cut, be sure that the lower guard has closed

held upside down in a vise. This is extremely
dangerous and can lead to serious accidents.

34. Some material contains chemicals which may be
toxic. Take caution to prevent dust inhalation and
skin contact. Follow material supplier safety data.
35. Do not stop the blades by lateral pressure on
the saw blade.
36. Always use blades recommended in this
manual. Do not use any abrasive wheels.
37. Keep blade sharp and clean. Gum and wood
pitch hardened on blades slows saw and
increases potential for kickback. Keep blade
clean by first removing it from tool, then cleaning
it with gum and pitch remover, hot water or
kerosene. Never use gasoline.
38. Wear a dust mask and hearing protection
when use the tool.
