5.3 Incising the guide rail (special accessories)
Danger
Initial start-up
Trim the splinter guard 38 (Fig. 4)
with the saw blade prior to initial
start-up:
Place the rail onto a level support.
Put down the machine at the start of the rail with
the groove 24 (Fig. 6) in the base plate on the
spring of the rail.
Set the cutting depth to approx. 3 mm (1/8 in).
Switch on the machine and slide it evenly in
cutting direction across the entire length. The
newly formed cut edge on the splinter guard
serves as tracing edge for the saw blade, the
adjustable groove cutter and the slitting unit.
Place the rail onto the workpiece.
Push it against the workpiece and align it with
the marking. In order to fix the rail, clamp the rail
with the two screw clamps (special accessories)
39 (Fig. 8).
Set the cutting depth at the machine.
Switch on the machine and slide it evenly in
cutting direction.
Do not clean the rail with solvents – the anti-skid
coating could get damaged.
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.
