Operation

5.1 Initial operation

Personnel entrusted to work with the machine must
be made aware of the operating instructions, calling
particular attention
instructions".
It is mandatory to check whether all safety devices
are attached and functional. This applies especially to
the ease of movement of the protective hood.

5.2 Switching on and off

Danger
Before switching the machine on
ensure that the cutter head can
move freely and that the moving
protective hood is closed.
Lead the connecting cable away to
the rear.
Take hold of the machine by the
handles.
Switch the machine on only when
the cutter head is not in contact
with the workpiece.

Switching on: First unlock the switch lock by
pressing the locking lever 12 (fig. 3). Then
actuate the shift lever 13 while pressing the
locking lever. As this is a switch without locking
device, the machine will only run for as long as
this gearshift lever is pressed.
The built-in electronic system provides for jerk-free
acceleration when the machine is switched on and
under load readjusts the speed to the fixed setting.
This electronic system also controls the motor upon
overload, e.g. the cutter head stays still. The machine
must then be unloaded until the cutter head has
reached its full speed. Then continue to cut at a lower
feed rate.
Switching off: Release the switch lever 13 to switch
the machine off. The built-in automatic break limits
the run-down time of the cutter head to approx. 5 s.
The switch lock takes effect automatically and
secures the bird's mouth cutter from inadvertantly
being switched on again.

5.3 Cutting bird's mouths

5.3.1 Mark bird's mouth
Angle and mark the two-sided bird's mouth mark at
the intersection. Pull the crevice A – B (fig. 4) over the
rafter.
5.3.2 Setting bird's mouth cutter
The following settings must be made before using the
machine:

Set the
The cutter head can be pivoted from 0 – 60°.
Release the clamping lever 8 (fig. 5) and set the
angle value (e.g. 30°) on the angle scale.
Tighten the clamping lever; The clamping
position of the lever can be set by pulling it out
in a vertical direction.

Set the
The cutter depth indicator depends on the set
bird's mouth angle "α". The depth indicator 4
can therefore be set from 0 – 60° and must
always be set to the same angle value "α" as
angle scale 6. Loosen the handle knob 9. Move
the depth indicator 4 on the left side of setting
scale 2 (marked "cutter head Ø 150 x 115") to
the desired angle value "α" (the upper edge is
the reading line) and the tighten the handle knob
again.

Set the
Unscrew the wing screw 10 (fig. 5). Turn the
handle 1 until the depth indicator 4 on the depth
scale 5 is at zero. Tighten the wing screw 10
(fig. 5).
The corner of the cutter of the
pivoted cutter head must be
positioned at the same level as the
base panel support.

Set
The mark indicator 16 (fig. 3) shows the position
of the corner of the blade at the horizontal level.
It must therefore always be set to the same
angle value "α" as the angle scale 6 (fig. 5).
Loosen the knurled knob 17 (fig. 3). Set the
mark indicator 16 with the outer right edge over
the mark scale 15 in the area of the marking
"Set cutter head Ø 150 x 115» to angle value
'α'". Tighten the knurled knob 17.
