Bosch Professional GKS 18V-68 GC Original Instructions Manual page 9

When restarting a saw in the workpiece, centre the
u
saw blade in the kerf so that the saw teeth are not en-
gaged into the material. If a saw blade binds, it may walk
up or kickback from the workpiece as the saw is restar-
ted.
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 im-
u
properly set blades produce narrow kerf causing excess-
ive friction, blade binding and kickback.
Blade depth and bevel adjusting locking levers must
u
be tight and secure before making the cut. If blade ad-
justment 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 the lower guard for proper closing before each
u
use. Do not operate the saw if the lower guard does
not move freely and close instantly. Never clamp or tie
the lower guard into the open position.If the saw is ac-
cidentally dropped, the 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.
The lower guard may be retracted manually only for
u
special cuts such as "plunge cuts" and "compound
cuts". Raise the lower guard by the retracting handle
and as soon as the 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 the 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.
Additional safety warnings
Do not allow the chip ejector to come into contact with
u
your hands. You may be injured by rotating parts.
Do not use the saw above the level of your head. Doing
u
so will mean you have inadequate control of the power
tool.
Use suitable detectors to determine if there are hid-
u
den supply lines or contact the local utility company
for assistance. Contact with electric cables can cause
Bosch Power Tools
fire and electric shock. Damaging gas lines can lead to ex-
plosion. Breaking water pipes causes property damage.
Hold the power tool firmly with both hands and make
u
sure you have a stable footing. The power tool can be
more securely guided with both hands.
Do not operate the power tool when stationary . It is
u
not suitable for operation with a saw table.
When performing plunge cuts which are not right-
u
angled, secure the guide plate of the saw so that it will
not shift sideways.In the event of a sideways shift, the
saw blade may become jammed, which could lead to kick-
back.
Secure the workpiece. A workpiece clamped with
u
clamping devices or in a vice is held more secure than by
hand.
Always wait until the power tool has come to a com-
u
plete stop before placing it down. The application tool
can jam and cause you to lose control of the power tool.
Do not use HSS saw blades. Such saw blades can easily
u
break.
Do not saw any ferrous metals. Hot chips may ignite the
u
dust extractor.
Wear a dust mask.
u
In case of damage and improper use of the battery, va-
u
pours may be emitted. The battery can set alight or ex-
plode. Ensure the area is well ventilated and seek medical
attention should you experience any adverse effects. The
vapours may irritate the respiratory system.
Do not open the battery. There is a risk of short-circuit-
u
ing.
The battery can be damaged by pointed objects such
u
as nails or screwdrivers or by force applied externally.
An internal short circuit may occur, causing the battery to
burn, smoke, explode or overheat.
Only use the battery with products from the manufac-
u
turer. This is the only way in which you can protect the
battery against dangerous overload.
Protect the battery against heat, e.g. against
continuous intense sunlight, fire, dirt, water
and moisture. There is a risk of explosion and
short-circuiting.
Caution! When using the power tool with Bluetooth
u
fault may occur in other devices and systems, aero-
planes and medical devices (e.g. pacemakers, hearing
aids). Also, damage to people and animals in the im-
mediate vicinity cannot be completely excluded. Do
not use the power tool with Bluetooth
medical devices, petrol stations, chemical plants,
areas with a potentially explosive atmosphere or in
blasting areas. Do not use the power tool with
®
Bluetooth in aircraft. Avoid using the product near
your body for extended periods.
