Adjusting the Parallel Guide
The parallel guide 10 can be positioned either
left (black scale) or right (silver scale) from the
saw blade.
The mark in the lens 27 indicates the set clear-
ance of the parallel fence to the saw blade on
the scale 1.
Position the parallel guide on the desired side of
the saw blade (see "Mounting the Parallel
Guide", page 42).
With the Saw Table not Extended
– Loosen clamping handle 35 of parallel guide
10.
Move the parallel guide until the mark in the
lens 27 indicates the desired clearance to
the saw blade.
When the saw table is not extended, the bot-
tom labelling of the silver scale applies 1.
– To lock the parallel guide, press clamping
handle 35 down again.
With the Saw Table Extended (see figure N)
– Position the parallel guide on the right side
of the saw blade.
Move the parallel guide until the mark in the
lens 27 indicates 26 cm on the bottom scale.
To lock the parallel guide, press clamping
handle 35 down again.
– Completely pull tensioning lever 15 of the
saw-table extension upward.
– Pull saw-table extension 14 outward until
clearance indicator 51 indicates the desired
clearance to the saw blade on the top scale.
– Press tensioning lever 15 downward.
The saw-table extension is now locked.
Adjusting the Auxiliary Parallel Guide
(see figure O)
When sawing narrow workpieces and bevel an-
gles, the auxiliary parallel guide 37 must be
mounted to parallel guide 10.
The auxiliary parallel guide can be mounted left
or right to parallel guide 10 as required.
Bosch Power Tools
When sawing short workpieces, these can be-
come jammed between the parallel guide and
the saw blade, be caught by the rotating saw
blade, and be thrown from the machine.
Therefore, adjust the auxiliary parallel guide in
such a manner that its guiding end is located be-
tween the front saw blade tooth and the saw
blade centre.
– For this, loosen all wing nuts and move the
auxiliary parallel guide until only the two
front screws can be used for fastening.
– Tighten the wing nuts again.

Adjusting the Riving Knife

The riving knife 25 prevents the saw blade 26
from becoming jammed in the saw cut. Other-
wise, 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 posi-
tion.
The machine is supplied with the riving knife
correctly adjusted.
Adjusting the height of the riving knife
(see figure P)
For sawing grooves, the height of the riving knife
must be adjusted.
Use the machine for grooving or rebating
only with an appropriately suitable protec-
tive device (e. g. a tunnel blade guard).
– Loosen clamping lever 8 until blade guard 6
can easily be pulled from the recess in the
riving knife 25.
To protect the blade guard against damage,
deposit it in the provided holding fixture 33
on the housing (also see figure Y1).
