Adjusting the Auxiliary Parallel Guide 
(see figure O)
When sawing narrow workpieces and bevel angles, the auxil-
iary parallel guide 37 must be mounted to parallel guide 10.
The auxiliary parallel guide can be mounted left or right to par-
allel guide 10 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 scr ews  c an be  used  f or  f as-
tening.
– 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. 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 adjusted.
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 lever 8.1 or clamping screw 8.2 until 
blade guard 6.x can easily be pulled from the recess in riv-
ing knife 25.
To protect the blade guard against damage, deposit it in 
the provided holding fixture 33 on the housing (also see 
figure Y1).
–Turn crank 19 clockwise to the stop, so that the saw blade 
26 is in the highest possible position above the saw table.
–Push the riving knife 25 down to the stop.
Starting Operation
Observe the mains voltage! The voltage of the power 
source must correspond with the data on the type plate of 
the machine.
Switching On (see figure Q1)
To save energy, only switch the power tool on when using it.
– Tilt safety flap 20 upward.
– To start the operation, press the green ON button 52.
– Tilt safety flap 20 down again.Switching Off (see figure Q2)
– Press on the safety flap 20.
Power Failure
The ON/OFF switch is a so-called non-voltage switch, which 
prevents the power tool from restarting after a power failure 
(e. g., when the mains plug is pulled during operation).
To restart the operation of the machine afterwards, the green 
ON button 52 must be pressed again.
Working Advice
General Sawing Instructions
For all cuts, it must first be ensured that the saw blade 
at no time can come in contact with the stops or other 
machine parts.
Use the machine for grooving or rebating only with an 
appropriately suitable protective device (e. g. a tunnel 
blade guard).
Do not use the machine for cutting slots (stopped 
grooves).
Protect the saw blade against impact and shock. Do not sub-
ject the saw blade to lateral pressure.
The riving knife must be in alignment with the saw blade to 
avoid jamming of the workpiece.
Do not saw warped/bent workpieces. The workpiece must al-
ways have a straight edge to face against the parallel guide.
Always keep/store the push stick with the power tool.
Position of the Operator (see figure R)
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.
Observe the following instructions:
– Hold the workpiece securely with both hands and press it 
firmly against the saw table.
– When sawing narrow workpieces and bevel angles, always 
use the supplied hold-down stick 23 and the auxiliary par-
allel guide 37.
