Using the Universal Guide as a Parallel Guide
(see figure N2)
– Mount the universal guide 1 left or right on
the saw table 7 or the table extension 27.
(see "Mounting the Universal Guide",
page 44)
Note: When sawing bevel angles, the univer-
sal guide should be mounted to the right of
the saw blade.
– Depending on the workpiece size and on the
set bevel angle, mount the fence 36 upright
or flat to the universal guide 1. (see "Mount-
ing the Fence to the Universal Guide",
page 44)
Note: When sawing, workpieces can become
jammed between the universal guide and the
saw blade, be caught by the rotating saw
blade, and be thrown from the machine.
Therefore, adjust the fence 36 in such a man-
ner that its guiding end ends in the area be-
tween the saw blade centre and the riving
knife.
For this, loosen wing bolt 34, move the fence
and retighten the wing bolt again.
– Adjust a 0° mitre angle. (see "Adjusting Mitre
Angles", page 46)
– Loosen wing bolt 37 and move the guide rail
31 to the desired clearance.
The scale 14 indicates the clearance be-
tween saw blade and fence.
– Tighten wing bolt 37 again.
Adjusting the Riving Knife
The riving knife 4 prevents the saw blade 28
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.
1 609 929 W71 | (30.3.11)
– 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 figures O1–O2)
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).
– Remove the blade guard 3 and the laser unit
41 from the riving knife 4.
– Loosen the screws of insert plate 5 with Al-
len key 13 and remove the insert plate from
the saw table.
– Turn crank 18 clockwise to the stop, so that
the saw blade 28 is in the highest possible
position above the saw table.
Adjust a saw blade bevel angle of 45°. (see
"Adjusting Bevel Angles", page 47)
– Loosen screws 60 with Allen key 13, until the
riving knife 4 can be moved.
– Adjust to a 0° bevel angle.
Turn crank 18 in anticlockwise direction, un-
til the teeth of the saw blade 28 are posi-
tioned at the desired height (= groove depth)
above the saw table 7.
– Move riving knife 4 downward until the riving
knife is no less than 5 mm below the upper
saw teeth.
– Turn crank 18 clockwise to the stop, so that
the saw blade 28 is in the highest possible
position above the saw table.
Adjust a saw blade bevel angle of 45°.
– Retighten the screws 60 of the riving knife.
– Mount the insert plate 5 into the saw table.
