Practical Advice - Bosch GCM 8 SJL Professional Notice Originale

– Loosen the locking knob (21) if it is tightened.
– Pull the lever (22) and at the same time press the locking
clamp (20) until this clicks into the slot provided for it.
This means the saw table can now move freely.
– Turn the saw table (16) left or right by the locking knob
until the angle indicator (24) shows the required mitre
angle.
– Retighten the locking knob (21).
– To loosen the lever (22) again (for setting standard mitre
angles), pull the lever upwards.
The locking clamp (20) springs back into its original posi-
tion and the lever (22) can click back into the detents
(25).
Adjusting bevel angles
To ensure precise cuts, the basic settings of the power tool
must be checked and adjusted as necessary after intensive
use.
Experience and suitable special tools are required for this.
A Bosch after-sales service point will handle this work
quickly and reliably.
Setting standard bevel angles (see figure H)
For quick and precise setting of frequently used bevel
angles, stops have been provided for the angles 0°, 45°,
22.5° and 33.9°.
– Loosen the clamping lever (39).
– Adjust the stops (29) or (42) as follows:
Bevel Stop Setting
angle
0° (42) Slide the stop all the way back
45° (29) Turn the stop all the way to the front
22.5° (29) Turn the stop to the centre
33.9° (29) Turn the stop to the back
– Swivel the tool arm by the handle (9) into the required
position.
– Retighten the clamping lever (39).
Setting any bevel angle
The bevel angle can be set between -2° and +47°.
– Loosen the clamping lever (39).
– Turn the stop (29) all the way to the back and pull the
stop (42) all the way to the front.
The full swivel range is now available.
– Swivel the tool arm left or right by the handle (9) until the
angle indicator (41) shows the required bevel angle.
– Hold the tool arm in this position and retighten the clamp-
ing lever (39).
Start-up
Products that are only sold in AUS and NZ: Use a resid-
u
ual current device (RCD) with a nominal residual current
of 30 mA or less.
Pay attention to the mains voltage. The voltage of the
u
power source must match the voltage specified on the
Bosch Power Tools
rating plate of the power tool. Power tools marked
with 230 V can also be operated with 220 V.
Switching on (see figure I)
– To switch on the power tool, first slide the lock-off
button (7) to the middle and then press and hold the on/
off switch (8).
Note: For safety reasons, the on/off switch (8) cannot be
locked; it must remain pressed during the entire operation.
Switching off
– To switch off, release the on/off switch (8).
Starting current limitation
The electronic starting current limitation feature restricts the
power of the power tool when it is switched on and enables
operation using a 16 A fuse.
Note: If the power tool runs at full speed immediately after
being switched on, this means that the starting current limit-
ation has failed. The power tool must be sent to the after-
sales service without delay. For addresses, see: After-sales
service and advice on using products.

Practical advice

Marking the Cutting Line (see figure J)
A laser beam shows you the cutting line of the saw blade.
This allows for exact positioning of the workpiece for sawing,
without having to open the retracting blade guard.
– To activate this, turn on the laser beam using the
switch (38).
– Align your mark on the workpiece with the right-hand
edge of the laser line.
Note: Before sawing, check whether the cutting line is still
indicated correctly. The laser beam can be misaligned due to
vibrations from intensive use, for example.
Position of the operator (see figure K)
Do not stand in line with the saw blade in front of the
u
power tool. Always stand to the side of the saw blade.
This protects your body against possible kickback.
– Keep hands, fingers and arms away from the rotating saw
blade.
– Do not reach one hand across the other when in front of
the tool arm.
