5.4 Cutting depth adjustment
The cutting depth can be set between 0 and 26 mm (0
and 1 1/32 in.), graded in 1 mm (3/64 in.) steps.
Proceed as follows:
• Adjust the indicator 10 (Fig. 8) by turning. The top
position is for working with guide rail, the bottom
position for working without guide rail.
• Set the cutting depth with the depth stop 11 (Fig. 5)
according to the scale. The limit stop has a 1 mm
(3/64 in.) latching mechanism.
• To set intermediate measures, turn the cylinder
head bolt 12 (Fig. 5) with the Allen key 4 (brackets
Fig. 2). One turn corresponds to 1 mm (3/64 in.),
one scale line on the screw head corresponds to 0.1
mm (1/128 in.).
5.5 Grooves
Set the desired cutting depth according to chapter 5.4.
Carry out groove cutting using a
guiding device. Wider grooves are
achieved by laterally offsetting the
guiding device from the right to the
left.
5.6 Handling
Danger
The groove-cutting machine is not
suitable for freehand guidance. The
use of parallel stop, roller edge
guide, KSS rail or F-rail guide is
compulsory. In case of the KSS
model, place the workpiece onto
the support frame in a stable
manner.
5.7 Plunge cuts
Danger
Risk of backlash during plunge
cuts! Prior to plunging, place the
machine with the rear edge of its
base plate against a limit stop
fastened on the workpiece. When
using the guide rail (special
accessories) you must fasten the
limit stop available as special
accessory on the guide rail. Keep
a firm hold on the machine handle
during plunging and push the saw
lightly forward!
5.8 Working according to marking
The base plate has two fixed marking indicators 17 and
25 (Fig. 1). Marking indicator 25 corresponds to the
centre of the plasterboard and aluminium compound
milling cutter. Marking indicator 17 corresponds to the
inside of the saw blade, adjustable groove cutter and
slitting unit.
• Always use a guiding device.
• Secure the workpiece against dislocation and
arrange the workpiece supports such that the tool
underneath the workpiece is running freely (in case
of a severing cut).
• Hold the machine by the handle and place the front
part of the base plate onto the workpiece.
• Switch on the groove-cutting machine (see 5.2).
Plunge to the set cutting depth and slide the
machine evenly forward in the direction of the cut.
• After the end of the cut, switch off the groove-cutting
machine by releasing the gearshift lever 8 (Fig. 5).
• While it is resting on the workpiece, pull the machine
back into home position and in this position remove
it from the workpiece. Proceeding in this manner
ensures that the retractable saw guard is completely
closed.
• The saw unit tilts back into the top locked position.
5.9 Working with the parallel stop
The parallel stop 18 (Fig. 2) is used to work parallel to
an already existing edge. The limit stop can be
attached to the left or right of the machine. The cutting
range on the right-hand side amounts to approx. 170
mm (6 45/64 in.)and on the left-hand side to approx.
345 mm (13 37/64 in.).
