Switching Off; Practical Advice - Bosch GCM 80 SJ Manual Original

Left
45°; 22.5°; 15°
– Loosen the locking knob (25) if it is tightened.
– Push the lever (26) and turn the saw table (22) left or
right to the required detent.
– Release the lever again. The lever must be felt to engage
in the detent.
– Retighten the locking knob (25).
Setting Bevel Angles (see figure I)
The bevel angle can be set between 0° and 45°.
– Pull the adjustable fence (6) all the way out.
– Loosen the clamping handle (10).
– Use the handle (16) to swivel the tool arm until the angle
indicator (32) shows the required bevel angle.
– Hold the tool arm in this position and retighten the clamp-
ing handle (10).
End stops are provided on the housing that enable the
standard angles of 0° and 45° to be set quickly and accur-
ately.
– Pull the adjustable fence (6) all the way out.
– Loosen the clamping handle (10).
– Swivel the tool arm by the handle (16) all the way to the
right (0°) or all the way to the left (45°).
– Retighten the clamping handle (10).
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.
Switching on (see figure J)
– To start the tool, press the on/off switch (15) and keep it
pressed.
Note: For safety reasons, the on/off switch (15) cannot be
locked; it must remain pressed during the entire operation.
The tool arm can only be guided downwards by pushing the
locking switch (17).
– For sawing, the locking switch (17) must therefore be
pushed while the on/off switch (15) is pressed.

Switching off

– To switch off, release the on/off switch (15).
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.

Starting current limitation
Right
The electronic starting current limitation restricts the power
15°; 22.5°; 45°
consumption when the power tool is switched on and en-
ables operation with 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 and restarting protection mechanisms have failed. The
power tool must be sent to the after-sales service without
delay.

Practical advice

General sawing instructions
Always tighten the locking knob (25) and the clamp-
u
ing handle (10) firmly before sawing. Otherwise the
saw blade can become wedged in the workpiece.
Always tighten the locking knob (25) and the clamp-
u
ing lever 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.
Only saw materials which are permitted within the scope of
the intended use.
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 downwards. When the tool
arm is guided upwards, the retracting blade guard must
close again over the saw blade and lock in the uppermost po-
sition of the tool arm.
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.
