use (see "Checking and Adjusting the Basic Settings",
page 42).
The bevel angle can be set between 47° (left side) and 47°
(right side).
For quick and precise setting of frequently used bevel
angles, stops have been provided for the angles 0°, 22.5°,
45° and 47°.
Setting the left-hand bevel angle range (45° to 0°)
– Pull the left-hand adjustable fence (5) all the way out (see
"Moving the fence", page 38).
– Loosen the clamping handle (13).
– Use the handle (1) to swivel the glide arm (28) to the left
until the angle indicator (33) shows the required bevel
angle.
– Hold the glide arm (28) in this position and retighten the
clamping handle (13).
The clamping force of the clamping handle must hold the
glide arm securely in place at any bevel angle.
Setting the Right-hand Bevel Angle Range (0° to 45°)
(see figure J)
– Pull the right-hand adjustable fence (5)all the way out
(see "Moving the fence", page 38).
– Loosen the clamping handle (13).
– Use the handle (1) to tilt the glide arm (28) slightly to the
left from the 0° position and turn the rotary knob (39) un-
til the required bevel angle range is shown.
– Use the handle (1) to swivel the glide arm (28) to the
right until the angle indicator (21) shows the required
bevel angle.
– Hold the glide arm (28) in this position and retighten the
clamping handle (13).
The clamping force of the clamping handle must hold the
glide arm securely in place at any bevel angle.
Setting the Standard 0° bevel angle
To enable the standard 0° bevel angle to be reset
easily, the rotary knob (39) engages in the left-
hand bevel angle range.
– Swivel the glide arm (28) from the right to the 0° position.
Setting the entire bevel angle range (–47° to +47°)
– Pull both adjustable fences (5) all the way out (see "Mov-
ing the fence", page 38).
– Loosen the clamping handle (13).
Bosch Power Tools
– Use the handle (1) to tilt the glide arm (28) slightly to the
left from the 0° position and turn the rotary knob (39) un-
til the required bevel angle range is shown.
– Use the handle (1) to swivel the glide arm (28) to the left
or right until the angle indicator (33) or (21) shows the
required bevel angle.
– Hold the glide arm (28) in this position and retighten the
clamping handle (13).
The clamping force of the clamping handle must hold the
glide arm securely in place at any bevel angle.
Setting the Standard 22.5° Bevel Angle (see figure K)
Pull the adjustment knob (34) all the way out and turn it 90°.
Then use the handle (1) to swivel the glide arm (28) until
you hear the glide arm engage.
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.
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 L)
– To start the power tool, first slide the lock-off switch (2)
to the middle and then press and hold the on/off switch
(59).
Note: For safety reasons, the on/off switch (59) cannot be
locked; it must remain pressed during the entire operation.

Switching off

– To switch off, release the on/off switch (59).
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: (see "After-
sales service and advice on using products", page 44).

Practical advice

General sawing instructions
Always tighten the locking knob (11) and the clamp-
u
ing handle (13) 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.
