Starting Operation
f
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)
– Tilt safety flap
22
upward.
– To start the operation, press the green ON button
54
.
– Tilt safety flap
22
down again.
Switching Off (see figure Q2)
– Press on the safety flap
22
.
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
54
must be pressed again.
Working Advice
General Sawing Instructions
f
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.
f
Use the machine for grooving or rebating only with an
appropriately suitable protective device (e. g. a tunnel
blade guard).
f
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)
f
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
16
and the auxiliary par-
allel guide
38
.
Maximum Workpiece Dimensions
Sawing
Sawing Straight Cuts
– Adjust the parallel guide
9
to the requested cutting width.
(see “Adjusting the Parallel Guide”, page 21)
– Position the workpiece on the saw table in front of the
blade guard
6
.
– Raise or lower the saw blade with the crank
21
so that the
upper saw teeth project approx. 5 mm above the work-
piece surface.
– Adjust the blade guard according to the workpiece height.
When sawing, the blade guard must always face lightly
against the workpiece.
(see “Adjusting the Blade-guard Height”, page 19)
– Switch on the machine.
– Saw through the workpiece applying uniform feed.
– Switch off the machine and wait until the saw blade has
come to a complete stop.
Sawing Bevel Angles
– Adjust the desired bevel angle. (see “Adjusting Bevel An-
gles”, page 21)
– Adjust the height of blade guard
6
in such a manner that
the bottom edge of the blade guard is clear of the work-
piece.
For this, loosen clamping lever
26
, adjust the appropriate
height of blade guard
6
and then tighten the clamping lever
again.
– Afterwards, adjust the height of the side protector
71
,
which additionally covers the saw blade when sawing
bevel angles. The side protector must be clear of the work-
piece.
For this, loosen locking screw
72
, adjust the appropriate
height of side protector
71
and then tighten the locking
screw again.
– Follow the worksteps in section “Sawing Straight Cuts” ac-
cordingly.
Sawing Mitre Angles (see figure S)
– Adjust the requested mitre angle (see “Adjusting Mitre An-
gles”, page 21)
– Place the workpiece against profile rail
29
.
The profile may not be on the cutting line. If so, loosen
knurled nut
42
and move the profile.
– Raise or lower the saw blade with the crank
21
so that the
upper saw teeth project approx. 5 mm above the work-
piece surface.
– Adjust the blade guard according to the workpiece height.
When sawing, the blade guard must always face lightly
against the workpiece.
(see “Adjusting the Blade-guard Height”, page 19)
– Switch on the machine.
– With one hand, press the workpiece against the profile rail
and with the other hand, slowly move the angle stop via
locking knob
51
toward the front in guide groove
5
.
– Switch off the machine and wait until the saw blade has
come to a complete stop.
