Setting Any Mitre Angle (see figure I)
The mitre angle can be set between 52° (left side) and 60°
(right side).
– Loosen the locking knob (11) if it is tightened.
– Pull the lever (12) and at the same time press the locking
clamp (10) until this clicks into the slot provided for it.
This means the saw table can now move freely.
– Turn the saw table (37) left or right by the locking knob
until the angle indicator (57) shows the required mitre
angle.
– Retighten the locking knob (11).
– To loosen the lever (12) again (for setting standard mitre
angles), pull the lever upwards.
The locking clamp (10) springs back into its original posi-
tion and the lever (12) can click back into the detents
(14).
Adjusting vertical mitre 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 26).
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 22).
– Loosen the clamping handle (13).
– Use the handle (1) to swivel the glide arm (27) to the left
until the angle indicator (32) shows the required bevel
angle.
– Hold the glide arm (27) 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 22).
– Loosen the clamping handle (13).
– Use the handle (1) to tilt the glide arm (27) slightly to the
left from the 0° position and turn the rotary knob (38) un-
til the required bevel angle range is shown.
– Use the handle (1) to swivel the glide arm (27) to the
right until the angle indicator (20) shows the required
bevel angle.
Bosch Power Tools
– Hold the glide arm (27) 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 (38) engages in the left-
hand bevel angle range.
– Swivel the glide arm (27) 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 22).
– Loosen the clamping handle (13).
– Use the handle (1) to tilt the glide arm (27) slightly to the
left from the 0° position and turn the rotary knob (38) un-
til the required bevel angle range is shown.
– Use the handle (1) to swivel the glide arm (27) to the left
or right until the angle indicator (32) or (20) shows the
required bevel angle.
– Hold the glide arm (27) 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 (33) all the way out and turn it 90°.
Then use the handle (1) to swivel the glide arm (27) 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.
