5.2.3 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 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.

c) Lower guard should be retracted manually only

for special cuts such as “plunge cuts” and

“compound cuts.” Raise lower guard by re-

tracting handle 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.

5.3 Additional safety instructions

5.3.1 Personal safety

a) Wearear protectors.Exposureto noise cancause

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) Do not operate the power tool without the pro-

tective devices that belong to it.

d) Operate the power tool only as intended and

when it is in faultless condition.

e) Improve the blood circulation in your fingers by

relaxing your hands and exercising your fingers

during breaks between working.

f) Switch the power tool on only after bringing it

into position at the workpiece.

g) Remove the battery before storing or transport-

ing the power tool.

h) Always guide the power tool away from your

body when working with it.

i) Do not work with the power tool overhead.

j) Do not attempt to brake the speed of the saw

blade by pressing it to the side.

k) Do not touch the clamping flange or the clamp-

ing screw while the power tool is running.

l) Never press the drive spindle lock button while

the saw blade is rotating.

m) Never direct the power tool toward persons.

n) Adjust the pressure applied to the saw blade

and the material being cut so that the blade

does not stall, possibly causing the power tool

to kick back.

o) Metal cuttings are sharp and present a risk of

injury. Keep your clothing closed so that metal

cuttings cannot find their way into your gloves,

shoes or other parts of your clothing.

p) Pay attention to the direction in which the metal

chips fly when sawing. The chips are hot and

may cause fires or lead to burning and cutting

injuries.

q) Children must be instructed not to play with the

power tool.

r) The power tool is not intended for use by chil-

dren, by debilitated persons or those who have

received no instruction or training.

s) WARNING: Some dust created by grinding,

sanding, cutting and drilling contains chem-

icals known to cause cancer, birth defects,

infertility or other reproductive harm; or seri-

ous and permanent respiratory or other injury.

Some examples of these chemicals are: lead from

lead-based paints, crystalline 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 approved safety

equipment, such as respiratory protection ap-

propriate 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 protective

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

absorption of harmful chemicals.
