Adjusting the Riving Knife

The riving knife 7 prevents the saw blade 32 from becoming
jammed in the saw cut. Otherwise, there is danger of kickback
when the saw blade becomes wedged in the workpiece.
Always pay attention that the riving knife is properly adjusted:
– The radial clearance between saw blade and riving knife
may not exceed 5 mm (max.).
– The thickness of the riving knife must be smaller than the
cutting width and greater than the blade thickness.
– The riving knife must always be in a line to the saw blade.
– For normal separating cuts, the riving knife must always be
in the highest possible position.
The machine is supplied with the riving knife correctly adjusted.
Adjusting the height of the riving knife (see figure H)
For sawing grooves, the height of the riving knife must be ad-
justed.
 Use the machine for grooving or rebating only with an
appropriately suitable protective device (e. g. a tunnel
blade guard).
– Loosen clamping lever 46.1 or clamping screw 46.2 until
blade guard 5.x can easily be pulled from the recess in riv-
ing knife 7.
To protect the blade guard against damage, deposit it in
the provided holding fixture 22 on the housing (also see
figure R1).
– Turn crank 20 clockwise to the stop, so that the saw blade
32 is in the highest possible position above the saw table.
– Push the riving knife 7 down to the stop.

Starting Operation

 Observe the mains voltage! The voltage of the power
source must correspond with the data on the type plate of
the machine.
Switching On (see figure I1)
To save energy, only switch the power tool on when using it.
– Tilt safety flap 21 upward.
– To start the operation, press the green ON button 66.
Switching Off (see figure I2)
– Press on the safety flap 21.
Power Failure
The ON/OFF switch is a so-called non-voltage switch, which
prevents the power tool from restarting after a power failure
(e. g., when the mains plug is pulled during operation).
To restart the operation of the machine afterwards, the green
ON button 66 must be pressed again.

Working Advice

General Sawing Instructions
 For all cuts, it must first be ensured that the saw blade
at no time can come in contact with the stops or other
machine parts.
 Use the machine for grooving or rebating only with an
appropriately suitable protective device (e. g. a tunnel
blade guard).
Bosch Power Tools
 Do not use the machine for cutting slots (stopped
grooves).
Protect the saw blade against impact and shock. Do not sub-
ject the saw blade to lateral pressure.
The riving knife must be in alignment with the saw blade to
avoid jamming of the workpiece.
Do not saw warped/bent workpieces. The workpiece must al-
ways have a straight edge to face against the parallel guide.
Always keep/store the push stick with the power tool.
Position of the Operator (see figure J)
 Do not stand in a line with the saw blade in front of the
machine. Always stand aside of the saw blade. This pro-
tects your body against possible kickback.
– Keep hands, fingers and arms away from the rotating saw
blade.
Observe the following instructions:
– Hold the workpiece securely with both hands and press it
firmly against the saw table.
– When sawing narrow workpieces and bevel angles, always
use the supplied hold-down stick 13 and the auxiliary par-
allel guide 49.
Marking the Cutting Line (see figure K)
– Mark the saw blade width on the round yellow sticker 33.
This allows for exact positioning of the workpiece for saw-
ing, without having to open the blade guard.

Sawing
Sawing Straight Cuts
– Adjust the parallel guide 8 to the requested cutting width.
(see "Adjusting the Parallel Guide", page 36)
– Position the workpiece on the saw table in front of the
blade guard 5.x.
– Raise or lower the saw blade with the crank 20 so that the
upper saw teeth project approx. 5 mm above the work-
piece surface.
– Adjust the blade guard according to the workpiece height.
When sawing, the blade guard must always face lightly
against the workpiece.
– Switch on the machine.
– Saw through the workpiece applying uniform feed.
– Switch off the machine and wait until the saw blade has
come to a complete stop.
Sawing Bevel Angles
– Adjust the desired bevel angle. (see "Adjusting Bevel An-
gles", page 36)
– Follow the worksteps in section "Sawing Straight Cuts" ac-
cordingly.
