Position of the Operator (see figure N)
 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.
– Do not cross your arms when operating the tool arm.

45° (rightward) 45°
Minimum workpiece sizes (= all workpieces that can be
clamped left or right from the saw blade with the supplied
material clamp 29): 100 x 40 mm (length x width)

Replacing Insert Plates (see figure O)
The red insert plates 18 can become worn after prolonged
use of the machine.
Replace defective insert plates.
– Bring the power tool into the working position.
– Unscrew the screws 50 with a hex key (4 mm) and remove
the old insert plates.
– Insert the new right-hand insert plate.
– Screw the insert plate as far as possible to the right with
the screws 50 so that the saw blade does not come into
contact with the insert plate over the complete length of
the possible slide motion.
– Repeat the work steps in the same manner for the left-hand
insert plate.
Sawing
 Always tighten the locking knob 20 firmly before saw-
ing. Otherwise the saw blade can become wedged in the
workpiece.
Sawing without Slide Movement (Cutting Off)
(see figure P)
– For cuts without slide movement (small workpieces),
loosen the locking screw 33 in case it is tightened. Slide
the tool arm to the stop in the direction of the fence 14 and
retighten the locking screw 33.
– Set the required mitre angle as necessary.
– Firmly clamp the workpiece as appropriate for its
dimensions.
– Switch on the machine.
– Press locking switch 9 and slowly guide the tool arm down-
ward by the handle 8.
– Saw through the workpiece applying uniform feed.
Bosch Power Tools
– Switch off the machine and wait until the saw blade has
come to a complete stop.
– Guide the tool arm slowly upward.
Sawing with Slide Movement
– For cuts using the slide device 1 (wide workpieces), loosen
the locking screw 33 in case it is tightened.
– Set the required mitre angle as necessary.
– Firmly clamp the workpiece as appropriate for its
dimensions.
– Pull the tool arm away from the fence 14 far enough so that

Sawing Workpieces of the Same Length (see figure Q)
The material stop 37 (accessory) can be used for easily
sawing workpieces to the same length.
The material stop can be mounted on either side of the saw
table extension 13.
– Loosen lock screw 51 and swing the material stop 37 over
clamping screw 52.
– Retighten lock screw 51.
– Adjust the saw table extension 13 to the desired length
(see "Extending the Saw Table", page 27).
Adjusting the Depth Stop (Sawing Grooves) (see figure R)
The depth stop must be adjusted when a trench gap is to be
sawed.
– Swivel the depth stop 32 outward.
– Press locking lever 9 and tilt the tool arm to the desired
position.
– Turn adjusting screw 4, until the screw end touches depth
stop 32.
– Guide the tool arm slowly upward.
Special Workpieces
When sawing curved or round workpieces, these must be
especially secured against slipping. At the cutting line, no gap
may exist between workpiece, fence and saw table.
Provide for special fixtures, if required.
Checking and Adjusting the Basic Adjustment
 Before any work on the machine itself, pull the mains
plug.
To ensure precise cuts, the basic adjustment of the machine
must be checked and adjusted as necessary after intensive
use.
A certain level of experience and appropriate specialty tools
are required for this.
A Bosch after-sales service station will handle this mainte-
nance task quickly and reliably.
