• Support large panels to minimise the risk of
blade pinching and kickback. Large panels tend to
sag under their own weight� Supports must be placed
under the panel on both sides, near the line of cut and
near the edge of the panel� (See proper operation in
figure 13.2 and faulty operation in figure 13.1).
• Do not use dull or damaged blades. Unsharp-
ened or improperly set blades produce narrow kerf
causing excessive friction, blade binding and kick-
back�
• Blade depth and bevel adjusting locking le-
vers must be tight and secure before making
cut. If blade adjustment shifts while cutting, it may
cause binding and kickback�
• Use extra caution when sawing into existing
walls or other blind areas.
The protruding blade
may cut objects that can cause kickback�
Safety instructions for saws with outer pendulum
guard, with inner pendulum guard, with tow guard
• 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�
• 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�
• Lower guard may be retracted manually only
for special cuts such as "plunge cuts" and "com-
pound 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 operate automatically�
• Always observe that the lower guard is cover-
ing 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�
Caution! Chemical substances contained
in some dust particles generated during
sand, saws, grinding, drilling or other
construction activities may cause can-
cer, birth defect or harm to fertility.
WARNING! Chemical substances contained in some
dust particles generated during sand, saws, grinding,
drilling or other construction activities may cause can-
cer, birth defect or harm to fertility� Take some chemical
substances for example:
• Lead-based paint�
• Transparent silicon dioxide contained in the
bricks, cement and other stone products�
• Hazard level of arsenic and chromium produced
in chemically treated wood depends on frequency of
such kind of work� In order to avoid getting in touch
with such chemical substances: since the hazard de-
pends on the time you spend on such kind of work, you
should avoid contact with such chemical compositions�
• Please work in well ventilated conditions�
• Please wear approved protective equipment dur-
ing work such as dust mask with the design of filter -
ing tiny dusts�
Supplementary instructions for use of circular saw
• When using the power tool, you should pay attention
to the following points:
• the saw blade shall be intact without deformation,
crimp and lack of saw tooth or fracture;
• no saw blade made of high speed steel shall be
used;
• no blade of any grinding wheel shall be used for
the tool;
• saw blade not conforming to stipulations in the in-
structions shall not be used;
• do not exert lateral pressure on disk of the saw
blade to stop the saw blade;
• ensure correct operation of retraction mechanism
in all protection system;
• before change, adjustment or other maintenance
work is carried out, the plug shall be pulled out from
the power supply�
• When the power tool is used, advance speed shall
be controlled at a moderate level according to materi-
als of different hardness�
• When the power tool is used, no foreign matter such
as iron nail is allowed in processed wood; in case of
hard woody lump, advance speed shall be decreased�
• When protective cover is removed, operation is pro-
hibited�
• Saw blade shall be kept clean and sharp to reduce
the breakdown and rebound to the minimum�
• DANGER! During operation, your hands must get
away from the sawing area and shall not touch the saw
blade� When the saw blade is rotating, the workpiece
shall not be inserted� When the saw blade is still rotat-
ing, you shall not fetch the machined parts with hands�
• Be sure to clench the power tool tightly with hands�
Do not put your hand or fingers behind the circular saw.
If rebound occurs, the circular saw is likely to jump
back into your hands thus resulting in severe personal
injury (faulty operation is indicated in figure 16.1).
• When cutting is carried out, wider base portion of
circular saw shall be placed on stably supported part
of the workpiece rather than on the part to be cut down�
(proper operation is indicated in figure 17; fault opera -
tion is indicated in figure 16.2) If the workpiece is very
short or small, it should be clamped� Do not make an
attempt to support short workpiece with hands�
• Circular saw shall not be used upside down for saw-
ing operation because it is very dangerous and may
even cause severe accident (as shown in figure 18).
Before commencing operation
• Use the power tool only for cutting material recom-
mended by the manufacturer�
• The saw blade arrow must always point in the same
direction as the guard cover arrow�
• During operation never fix (bind, wedge, etc.) the
sliding guard cover open�
• Avoid blocking of the sliding guard cover or its clog-
ging with sawdust If this is the case switch off the
power tool, fix the malfunction and only then continue
operation�
During operation
• Never start cutting until the saw blade reaches its
full speed�
• Always process only one blank - this is the only way
to fix it properly.
