Switching Off; Practical Advice - Bosch GCM 8 SJL Professional HEAVY DUTY Originalbetriebsanleitung

Pull the saw table extension (13) all the way out (see " Ex-
tending the saw table (see figure B)", page 30).
– 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 (see "Checking and adjusting the basic settings",
page 32).
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
Pay attention to the mains voltage. The voltage of the
u
power source must match the voltage specified on the
rating plate of the power tool. Power tools marked
with 230 V can also be operated with 220 V.
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.
Switching on (see figure I)
– To start the power tool, first slide the lock-off switch (7)
to the middle and then press and hold the on/off switch
(8).
Bosch Power Tools
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 immediately. For addresses, see (see "After-
sales service and advice on using products", page 34).

Practical advice

General sawing instructions
Always tighten the locking knob (21) and the clamp-
u
ing lever (39) firmly before sawing. Otherwise the saw
blade can become wedged in the workpiece.
For all cuts, it must first be ensured that the saw blade
u
at no time can come in contact with the fence, screw
clamps or other machine parts. Remove any mounted
auxiliary stops or adjust them accordingly.
Protect the saw blade against impact and shock. Do not sub-
ject the saw blade to lateral pressure.
Do not saw warped/bent workpieces. The workpiece must
always have a straight edge to face against the fence.
The free end of long and heavy workpieces must have some-
thing placed underneath it or be supported.
Make sure that the retracting blade guard operates properly
and that it can move freely. The retracting blade guard must
open when the tool arm is guided downward. When the tool
arm is guided upward, the retracting blade guard must close
again over the saw blade and lock in the uppermost position
of the tool arm.
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 if the cutting line is still indic-
ated correctly (see "Adjusting the laser", page 33). The
laser beam can be misplaced due to vibrations from intens-
ive 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.
