17. Never force the saw. Push the saw forward at a
speed so that the blade cuts without slowing.
Forcing the saw can cause uneven cuts, loss of
accuracy, and possible kickback.
Lower guard function
18. Check lower guard for proper closing
before each use. Do not operate the saw if
lower guard does not move freely and close
instantly. Never clamp or tie the lower guard
into the open position. If saw is accidentally
dropped, lower guard may be bent. Raise the
lower guard with the retracting handle and make
sure it moves freely and does not touch the blade
or any other part, in all angles and depths of cut.
19. Check the operation of the lower guard spring.
If the guard and the spring are not operating
properly, they must be serviced before use.
Lower guard may operate sluggishly due to
damaged parts, gummy deposits, or a build-up of
debris.
20. Lower guard should be retracted manually
only for special cuts such as "plunge cuts"
and "compound cuts". Raise lower guard by
retracting handle and as soon as blade enters
the material, the lower guard must be released.
For all other sawing, the lower guard should oper-
ate automatically.
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 wood products
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. Use extra caution when cutting damp wood,
pressure treated lumber, or wood containing
knots. Maintain smooth advancement of tool with-
out decrease in blade speed to avoid overheating
the blade tips.
25. Do not attempt to remove cut material when
blade is moving. Wait until blade stops before
grasping cut material.Blades coast after turn off.
26. Avoid Cutting Nails. Inspect for and remove all
nails from lumber before cutting.
27. 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!

28. 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.
29. Never attempt to saw with the circular saw
held upside down in a vise. This is extremely
dangerous and can lead to serious accidents.
30. Some material contains chemicals which may be
toxic. Take caution to prevent dust inhalation and
skin contact. Follow material supplier safety data.
31. Do not stop the blades by lateral pressure on
the saw blade.
32. Do not use any abrasive wheels.
33. Only use the saw blade with the diameter that is marked
on the tool or specified in the manual. Use of an incorrectly
sized blade may affect the proper guarding of the blade or
guard operation which could result in serious personal injury.
34. Keep blade sharp and clean. Gum and wood pitch
hardened on blades slows saw and increases poten-
tial 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.
35. Wear a dust mask and hearing protection when
use the tool.
