21. Always observe that the lower guard is
covering the blade before placing saw down
on bench or floor.
An unprotected, coasting
blade will cause the saw to walk backwards,
cutting whatever is in its path. Be aware of the
time it takes for the blade to stop after switch is
released.
22. To check lower guard, open lower guard by
hand, then release and watch guard closure.
Also check to see that retracting handle does
not touch tool housing.
Leaving blade exposed
is VERY DANGEROUS and can lead to serious
personal injury.
Additional safety warnings
23. 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.
24. Do not attempt to remove cut material when
blade is moving. Wait until blade stops before
grasping cut material.
Blades coast after turn off.
25. Avoid Cutting Nails. Inspect for and remove
all nails from lumber before cutting.
26. 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!

27. Before setting the tool down after completing
a cut, be sure that the lower guard has closed
and the blade has come to a complete stop.
28. Never attempt to saw with the circular saw
held upside down in a vise. This is extremely
dangerous and can lead to serious accidents.

29. Some material contains chemicals which may
be toxic. Take caution to prevent dust
inhalation and skin contact. Follow material
supplier safety data.
30. Do not stop the blades by lateral pressure on
the saw blade.
31. Always use blades recommended in this
manual. Do not use any abrasive wheels.
32. 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.
33. Wear a dust mask and hearing protection
when use the tool.
