Adjusting Bevel Angles (Saw Blade) (see figure D)
The bevel angle can be set in a range from –1° to +47°.
– Turn locking lever 26 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 19 alongside the connecting link
until the angle indicator 61 indicates the desired bevel an-
gle.
– Hold the handwheel in this position and tighten locking le-
ver 26 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 E)
The mitre angle can be set in the range from 60° (left side) to
60° (right side).
– Loosen the locking knob 62 in case it is tightened.
– Turn the angle stop until the angle indicator 63 indicates
the requested mitre angle.
– Tighten the locking knob 62 again.
For quick and precise setting of frequently used mitre an-
gles, stop screw for the 45° angles (left and right) and 0°
have been provided for on angle stop 3.
– Loosen the locking knob 62 in case it is tightened.
– Tilt the adjustment piece 80 outward.
– Turn the angle stop in such a manner that the thread of the
desired stop screw is positioned rightward to the adjust-
ment piece.
– Tilt adjustment piece 80 inward and turn the angle stop un-
til the thread of the stop screw faces against the adjust-
ment piece.
– Tighten the locking knob 62 again.
Adjusting the Parallel Guide
The parallel guide 8 can be positioned either left (black scale)
or right (silver scale) from the saw blade.
The mark in the lens 64 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 34).
With the Saw Table not Extended
– Loosen clamping handle 47 of parallel guide 8.
Move the parallel guide until the mark in the lens 64 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 47 down
again.
With the Saw Table Extended (see figure F)
– Position the parallel guide on the right side of the saw
blade.
Move the parallel guide until the mark in the lens 64 indi-
cates 33 cm on the bottom scale.
To lock the parallel guide, press clamping handle 47 down
again.

– Completely pull the clamping handle 18 for the table width
enlargement upward.
– Pull table width enlargement 11 outward until clearance
indicator 65 indicates the desired clearance to the saw
blade on the top scale.
– Press clamping handle 18 downward.
The table width enlargement is now locked.
Adjusting the Auxiliary Parallel Guide
(see figure G)
When sawing narrow workpieces and bevel angles, the
auxiliary parallel guide 49 must be mounted to parallel guide
8.
The auxiliary parallel guide can be mounted left or right to par-
allel guide 8 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 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 adjust-
ed.
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.
