Starting Operation; Adjusting The Cutting Angle - Bosch GKS 7 1/4 PROFESSIONAL Manual De Instrucciones

The lower guard should be retracted manually on-
•
ly for special cuts such as "plunge cuts" and "com-
pound cuts". Raise the lower guard with the retract-
ing handle and as soon as blade enters the material,
the lower guard must be released.
the lower guard must operate automatically.
Always observe that the lower guard is covering the
•
saw blade before placing down the saw on a work-
bench or the floor. An unprotected, coasting blade will
cause the saw to travel backwards, cutting whatever is in its
path. Be aware of the run-on period of the saw.
• Do not reach into the saw dust ejector with your
hands. They could be injured by rotating parts.
Do not work overhead with the saw.
•
do not have sufficient control over the power tool.
Use suitable detectors to determine if utility lines are
•
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 damage
or may cause an electric shock.
Do not operate the power tool stationary.
•
signed for operation with a saw table.
Do not use high speed steel (HSS) saw blades.
•
saw blades can easily break.

Starting Operation

Observe correct mains voltage: The voltage of the power
source must agree with the voltage specified on the name-
plate of the machine.
Equipment marked with 230V can also be connected to
220V.
Switching On and Off
For starting operation of the machine, actuate the lock-off
button 2 first, and then press and hold the On/Off switch 1
afterwards.
To switch off the machine, release the On/Off switch 1.
For safety reasons the On/Off switch of the machi-
ne cannot be locked; it must remain pressed du-
ring the entire operation.
Adjusting the Cutting Depth (see figure
• Before any work on the machine itself, pull the mains
plug.
To achieve an optimum cut, the saw blade must not
protrude the material by more than 3 mm or one tooth (max-
C
imum). See figure .
To adjust the cutting depth, loosen winged screw 21 and
raise the saw from the base plate 11 or lower it towards the
base plate, respectively:
Raise → for smaller cutting depths
Lower → for greater cutting depths
Retighten the winged screw 21.

For all other sawing,
It is best to place the machine on the face side of the blade
guard.
Tilt the base plate away from the machine until the required
cutting angle is adjusted on the cutting angle scale 4.
Tighten the winged screws again.

The cutting mark 0° (8) indicates the position of the saw
blade for right-angled cuts.
The cutting mark 45° (7) indicates the position of the saw blade
for 45° cuts. The maximum tooth width of saw blade should be
taken into consideration according to tool specifications.
Both cutting marks include the width of the saw blade. Al-
ways guide the saw blade off of the drawn-up cutting line
so that the required measure is not reduced by the width
of the saw blade. For this, choose the corresponding notch
side of the cutting mark 0° (8) or 45° (7) as shown in the il-
lustration.
Note: It is best to carry out a trial cut.
