guard should operate automatically.
• 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.
Caution! Chemical substances con
tained in some dust particles generated
during sand, saws, grinding, drilling or
other construction activities may cause
cancer, 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 during
work such as dust mask with the design of filtering tiny
dusts.

the teeth at the back edge of the blade can dig into the
top surface of the wood causing the blade to climb out
of the kerf and jump back toward the operator.
• Kickback is the result of saw misuse and / or incorrect
operating procedures or conditions and can be avoid
ed by taking proper precautions as given below.
• Maintain a firm grip with both hands on the saw
and position your arms to resist kickback forces.
Position your body to either side of the blade, but
not in line with the blade. Kickback could cause the
saw to jump backwards, but kickback forces can be
controlled by the operator, if proper precautions are
taken.
• When blade is binding, or when interrupting a cut
for any reason, release the trigger and hold the saw
motionless in the material until the blade comes to
a complete stop. Never attempt to remove the saw
from the work or pull the saw backward while the
blade is in motion or kickback may occur. Investi
gate and take corrective actions to eliminate the cause
of blade binding.
• When restarting a saw in the workpiece, centre
the saw blade in the kerf and check that saw teeth
are not engaged into the material. If saw blade is
binding, it may walk up or kickback from the workpiece
as the saw is restarted.
• Support large panels to minimise the risk of blade
pinching and kickback. Large panels tend to sag un
der 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
11.2 and faulty operation in figure 11.1).
• Do not use dull or damaged blades. Unsharpened
or improperly set blades produce narrow kerf causing
excessive friction, blade binding and kick-back.
• Blade depth and bevel adjusting locking levers
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.

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 proper
ly, 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
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 materials 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
