9. 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
1. Check the lower guard for proper closing before each
use. Do not operate the saw if the lower guard does not
move freely and close instantly. Never clamp or tie the
lower guard into the open position. If the saw is acciden-
tally dropped, the 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.
2. Check the operation of the lower guard spring. If
the guard and the spring are not operating prop-
erly, they must be serviced before use. Lower guard
may operate sluggishly due to damaged parts, gummy
deposits, or a build-up of debris.
3. The lower guard may be retracted manually only for
special cuts such as "plunge cuts" and "compound
cuts". Raise the lower guard by the retracting han-
dle and as soon as the blade enters the material, the
lower guard must be released. For all other sawing,
the lower guard should operate automatically.
Always observe that the lower guard is cover-
4.
ing the blade before placing the 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.
5. 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 hous-
ing. Leaving blade exposed is VERY DANGEROUS
and can lead to serious personal injury.
Additional safety warnings
1. Use extra caution when cutting damp wood, pres-
sure treated lumber, or wood containing knots.
Maintain smooth advancement of tool without decrease
in blade speed to avoid overheating the blade tips.
Do not attempt to remove cut material when
2.
blade is moving. Wait until blade stops before
grasping cut material. Blades coast after turn off.
3. Avoid cutting nails. Inspect for and remove all
nails from lumber before cutting.
4. 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. If
the workpiece is short or small, clamp it down. DO
NOT TRY TO HOLD SHORT PIECES BY HAND!
5. Before setting the tool down after completing a
cut, be sure that the guard has closed and the
blade has come to a complete stop.
6. Never attempt to saw with the circular saw
held upside down in a vise. This is extremely
dangerous and can lead to serious accidents.
7. Some material contains chemicals which may be
toxic. Take caution to prevent dust inhalation and
skin contact. Follow material supplier safety data.
8. Do not stop the blades by lateral pressure on
the saw blade.
Do not use any abrasive wheels.
9.
10. 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.
Keep blade sharp and clean. Gum and wood pitch
11.
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.
12. Wear a dust mask and hearing protection when
use the tool.
13. Always use the saw blade intended for cutting
the material that you are going to cut.
14. Only use the saw blades that are marked with a speed
equal or higher than the speed marked on the tool.
15. (For European countries only)
Always use the blade which conforms to EN847-1.
