Adjusting the Cutting Angle
To ensure precise cuts, the basic adjustment of the machine
must be checked and adjusted as necessary after intensive
use (see "Checking and Adjusting the Basic Adjustment",
page 23).
Adjusting Bevel Angles (Saw Blade) (see figure K)
The bevel angle can be set in the range from –2° to 47°.
– Turn locking lever 19 in anticlockwise direction.
Note: By completely loosening the locking knob, the saw
blade tilts approx. to the 30° position by means of gravity
force.
– Push or pull handwheel 20 alongside the connecting link
until the angle indicator 49 indicates the desired bevel an-
gle.
– Hold the handwheel in this position and tighten locking le-
ver 19 again.
For quick and precise setting of the standard 0° and 45°
angles, factory-set stops have been provided for.
Adjusting Mitre Angles (Angle Stop) (see figure L)
The mitre angle can be set in the range from 60° (left side) to
60° (right side).
– Loosen the locking knob 51 in case it is tightened.
– Turn the angle stop until the angle indicator 52 indicates
the requested mitre angle.
– Tighten the locking knob 51 again.
Increasing the Size of the Saw Table (see figure M)
Long workpieces must be underlaid or supported at their free
end.
– Completely pull tensioning lever 17 of the saw-table exten-
sion upward.
– Pull out the saw-table extension 13 to the desired length.
– Press tensioning lever 17 downward.
The saw-table extension is now locked.
Adjusting the Parallel Guide
The parallel guide 9 can be positioned either left (black scale)
or right (silver scale) from the saw blade.
The mark in the lens 28 indicates the set clearance of the par-
allel guide 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 19).
With the Saw Table not Extended
– Loosen clamping handle 36 of parallel guide 9.
Move the parallel guide until the mark in the lens 28 indi-
cates the desired clearance to the saw blade.
When the saw table is not extended, the bottom labelling of
the silver scale applies 1.
– To lock the parallel guide, press clamping handle 36 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 28 indi-
cates 26 cm on the bottom scale.
Bosch Power Tools
To lock the parallel guide, press clamping handle 36 down
again.
– Completely pull tensioning lever 17 of the saw-table exten-
sion upward.
– Pull saw-table extension 13 outward until clearance indi-
cator 53 indicates the desired clearance to the saw blade
on the top scale.
– Press tensioning lever 17 downward.
The saw-table extension is now locked.
Adjusting the Auxiliary Parallel Guide
(see figure O)
When sawing narrow workpieces and bevel angles, the
auxiliary parallel guide 38 must be mounted to parallel guide
9.
The auxiliary parallel guide can be mounted left or right to par-
allel guide 9 as required.
When sawing workpieces, these can become jammed be-
tween 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 between the front saw blade
tooth and the front edge of the riving knife.
– For this, loosen all wing nuts and move the auxiliary paral-
lel guide until only the two front screws can be used for fas-
tening.
– Tighten the wing nuts again.
Adjusting the Riving Knife
The riving knife 25 prevents the saw blade 27 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 adjust-
ed.
Adjusting the height of the riving knife (see figure P)
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 screw 7 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 34 on the housing (also see
figure Y1).
– Turn crank 21 clockwise to the stop, so that the saw blade
27 is in the highest possible position above the saw table.
– Push the riving knife 25 down to the stop.
