7. Use extra caution when sawing into existing walls
or other blind areas. The protruding blade may cut
objects that can cause kickback.
8. ALWAYS hold the tool firmly with both hands.
NEVER place your hand, leg or any part of your
body under the tool base or behind the saw,
especially when making cross-cuts. If kickback
occurs, the saw could easily jump backwards over
your hand, leading to serious personal injury. (Fig. 5)
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 accidentally 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
properly, 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 handle 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.
4. Always observe that the lower guard is covering
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
housing. Leaving blade exposed is VERY
DANGEROUS and can lead to serious personal injury.
Additional safety warnings
1. 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.
2. Do not attempt to remove cut material when 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! (Fig. 6)
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.
(Fig. 7)
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.
9. Do not use any abrasive wheels.
10. 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.
11. 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.
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.
