21. Always observe that the lower guard is cov-
ering 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. Intended use
This tool is intended to cut masonry materials
only. Accumulated sawdust on the lower guard
and hub from other materials may effect the
proper closure of the lower guard which could lead
to serious personal injury.
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 material before cutting.
26. Place the wider portion of the saw base on that
part of the workpiece which is solidly sup-
ported, 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 inhala-
tion and skin contact. Follow material supplier
safety data.
30. Do not stop the blades by lateral pressure on
the saw blade.
31. Do not use any abrasive wheels.
32. Only use the saw blade with the diameter that
is marked on the tool or specified in the man-
ual. Use of an incorrectly sized blade may affect
the proper guarding of the blade or guard opera-
tion which could result in serious personal injury.
33. Keep blade sharp and clean. Gum hardened
on blades slows saw and increases potential for
kickback. Keep blade clean by first removing it
from tool, then cleaning it with gum remover, hot
water or kerosene. Never use gasoline.
34. Wear a dust mask and hearing protection when
use the tool.
