Operation as Table Saw
 Before any work on the machine itself, pull the mains
plug.
Working Position (see figure
If the power tool was used as a chop and mitre saw, then the
following steps must be carried out before using as a table
saw:
– Bring the power tool into the chop and mitre saw working
position. (see "Working Position", page 43)
– Loosen locking screw 44.
– Pull the adjustable fence 31 completely outward.
– Retighten the locking screw 44.
– Pull the lower saw blade cover 66 out of the groove of the
parallel guide 61.
– Insert the lower saw blade cover 66 into the saw table 22.
During operation as a table saw, the lower saw blade cover
66 must cover the bottom part of the saw blade.
– Set the vertical bevel angle to 0° and tighten the lock lever
37.
– Press release button 17 and slowly guide the tool arm by
handle 18 downward until the transport safety-lock 38 can
be pushed completely inward.
Preparing for Operation
Adjusting the Saw Blade Height (see figure
For safe operation, the correct working position of the saw
blade 7 to the workpiece must be adjusted. The maximum
workpiece height is 51 mm.
– Loosen both clamping levers 68 below the saw table 59.
– Tilt the protection guard 63 toward the rear to the stop and
position your workpiece next to the saw blade.
– Push the saw table down or pull it upward until the upper
saw teeth of the saw blade project approx. 1 mm above the
workpiece surface.
– Hold the saw table in this position and retighten the clamp-
ing levers again.
Adjusting the Parallel Guide (see figure
The parallel guide 61 can be positioned to the right of the saw
blade. The clearance indicator 69 indicates the clearance of
the parallel guide to the saw blade on the scale 65.
– Loosen the clamping knob 64.
This relieves the guide 71 at the rear of the parallel guide.
– Firstly, insert the parallel guide into the rear guide groove
of the saw table.
– Then position the parallel guide into the front guide groove
of the saw table.
The parallel guide can be moved variably now.
– Move the parallel guide until the clearance indicator 69 in-
dicates the requested clearance to the saw blade.
– To lock the parallel guide, push the clamping knob 64
downward again.
1 609 92A 3S7 | (24.2.17)
 Make sure that the parallel guide is always parallel to
the saw blade or that the sawblade/parallel guide clear-
ance increases toward the rear. Otherwise, danger is giv-
en that the workpiece is jammed between the saw blade
and the parallel guide.
Starting Operation
A)
Switching On (see figure
– For starting operation, press the green ON pushbutton 2
(I).
Switching Off
– Press the red OFF pushbutton 1 (O).
To save energy, only switch the power tool on when using it.
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 power tool, press the green ON pushbutton
2 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.
Protect the saw blade against impact and shock. Do not sub-
B)
ject the saw blade to lateral pressure.
Pay attention that the riving knife is in line with the saw blade.
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.
Do not use the power tool for joining, grooving or cutting slots.
Long workpieces must be underlaid or supported at their free
end. (see figure
Position of the Operator (see figure
 Do not stand in a line with the saw blade in front of the
machine. Always stand aside of the saw blade. This pro-
C)
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, expecially when working with-
out the guide.
– When sawing small workpieces, use the hold-down stick
provided.
Sawing
Sawing Straight Cuts
– Adjust the parallel guide 61 to the requested cutting width.
– (see "Adjusting the Parallel Guide", page 48)
– Position the workpiece on the saw table in front of the
blade guard 63.
