5.4 Safety instructions for Circular saw with
pendulum guard
a) 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.
b) 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.
c) Lower guard should be retracted manually only
for special cuts such as "plunge cuts" and "com-
pound cuts." Raise lower guard by retracting han-
dle and as soon as blade enters the material, the
lower guard must be released. For all other sawing,
the lower guard should operate automatically.
d) 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.

5.5 Additional safety instructions

5.5.1 Personal safety
a) Wear ear protectors. Exposure to noise can cause
hearing loss.
b) Always hold the power tool securely with both
hands on the grips provided. Keep the grips dry,
clean and free from oil and grease.
c) Breathing protection must be worn if the power
tool is used without a dust removal system for
work that creates dust.
d) Do not operate the power tool without the protec-
tive devices that belong to it.
e) Operate the power tool only as intended and when
it is in faultless condition.
f) Improve the blood circulation in your fingers by
relaxing your hands and exercising your fingers
during breaks between working.
g) Switch the power tool on only after bringing it into
position at the workpiece.
h) Remove the battery before storing or transporting
the power tool.
i) Always guide the power tool away from your body
when working with it.
Do not work with the power tool overhead.
j)
k) Do not attempt to brake the speed of the saw
blade by pressing it to the side.
l) Do not touch the clamping flange or the clamping
screw while the power tool is running.
m) The kerf must be free of obstructions. Do not saw
into screws and nails etc.
n) Never press the drive spindle lockbutton while the
saw blade is rotating.
o) Never direct the power tool toward persons.
p) Adjust the pressure applied to the saw blade and
the material being cut so that the blade doesn't
stall, possibly causing the power tool to kick back.
q) Children must be instructed not to play with the
power tool.
r) The power tool is not intended for use by children,
by debilitated persons or those who have received
no instruction or training.
s) WARNING: Some dust created by grinding, sand-
ing, cutting and drilling contains chemicals known
to cause cancer, birth defects, infertility or other
reproductive harm; or serious and permanent res-
piratory or other injury. Some examples of these
chemicals are: lead from lead-based paints, crys-
talline silica from bricks, concrete and other masonry
products and natural stone, arsenic and chromium
from chemically-treated lumber. Your risk from these
exposures varies, depending on how often you do
this type of work. To reduce exposure to these
chemicals, the operator and bystanders should
work in a well-ventilated area, work with ap-
proved safety equipment, such as respiratory pro-
tection appropriate for the type of dust generated,
and designed to filter out microscopic particles
and direct dust away from the face and body.
Avoid prolonged contact with dust. Wear protec-
tive clothing and wash exposed areas with soap
and water. Allowing dust to get into your mouth,
eyes, or to remain on your skin may promote absorp-
tion of harmful chemicals.
5.5.2 Power tool use and care
a) Secure the workpiece. Use clamps or a vice to
secure the workpiece. The workpiece is thus held
more securely than by hand and both hands remain
free to operate the power tool.
b) Check that the insert tools used are compatible
with the chuck system and that they are secured
in the chuck correctly.
5.5.3 Electrical safety
Before beginning work, check the working area (e.g.
using a metal detector) to ensure that no concealed
electric cables or gas and water pipes are present.
External metal parts of the power tool may become
live, for example, when an electric cable is damaged
accidentally. This presents a serious risk of electric shock.
5.5.4 Battery use and care
a) Observe the special instructions applicable to the
transport, storage and use of Li-ion batteries.
