Product Description And Specifications; Intended Use; Product Features; On/Off Switch - Bosch Professional GKS 190 Manual Original

14 | English
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 utility lines are
u
hidden in the work area or call the local utility com-
pany for assistance. Contact with electric lines can lead
to fire and electric shock. Damaging a gas line can lead to
explosion. Penetrating a water line causes property dam-
age or may cause an electric shock.
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.
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.
Products sold in GB only:
Your product is fitted with an BS 1363/A approved electric
plug with internal fuse (ASTA approved to BS 1362).
If the plug is not suitable for your socket outlets, it should be
cut off and an appropriate plug fitted in its place by an au-
thorised customer service agent. The replacement plug
should have the same fuse rating as the original plug.
The severed plug must be disposed of to avoid a possible
shock hazard and should never be inserted into a mains
socket elsewhere.
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.
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.
