Lower Guard Function; Residual Risks - Black & Decker BDCCS18 Mode D'emploi

Kickback causes and related warnings
kickback is a sudden reaction to a pinched, bound or
u
misaligned saw blade, causing an uncontrolled saw to lift
up and out of the workpiece toward the operator;
when the blade is pinched or bound tightly by the kerf
u
closing down, the blade stalls and the motor reaction
drives the unit rapidly back toward the operator;
if the blade becomes twisted or misaligned in the cut, the
u
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 avoided by taking proper
precautions as given below.
Maintain a firm grip with both hands on the saw and
u
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
u
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. Investigate and take
corrective actions to eliminate the cause of blade binding.
When restarting a saw in the workpiece, centre the
u
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
u
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.
Do not use dull or damaged blades. Unsharpened or
u
improperly set blades produce narrow kerf causing exces-
sive friction, blade binding and kickback.
Blade depth and bevel adjusting locking levers
u
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
u
other blind areas. The protruding blade may cut objects
that can cause kickback.

Lower guard function

Check lower guard for proper closing before each
u
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.
(Original instructions)
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
u
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.
Lower guard may be retracted manually only for
u
special cuts such as "plunge cuts" and "compound
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 covering the
u
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.
Safety of others
Never allow children, persons with reduced physical, sensory
or mental capabilities or lack of experience and knowledge or
people unfamiliar with these instructions to use the machine,
local regulations may restrict the age of the operator.

Residual risks

Additional residual risks may arise when using the tool which
may not be included in the enclosed safety warnings. These
risks can arise from misuse, prolonged use etc.
Even with the application of the relevant safety regulations
and the implementation of safety devices, certain residual
risks can not be avoided. These include:
Injuries caused by touching any rotating/moving parts.
u
Injuries caused when changing any parts, blades or ac-
u
cessories.
Injuries caused by prolonged use of a tool. When using
u
any tool for prolonged periods ensure you take regular
breaks.
Impairment of hearing.
u
Health hazards caused by breathing dust developed when
u
using your tool (example:- working with wood, especially
oak, beech and MDF.)
Vibration
The declared vibration emission values stated in the technical
data and the declaration of conformity have been measured in
accordance with a standard test method provided by EN62841
and may be used for comparing one tool with another. The
declared vibration emission value may also be used in a
preliminary assessment of exposure.
