"Plasterboard milling cutter"
The plasterboard milling cutter 35 (Fig. 10) is
equipped with 2 carbide reversible knives (4-blade)
and 4 carbide reversible knives (3-blade). If the
blades are becoming blunt, you can turn the
reversible knife 36 (Fig. 10) twice and the reversible
knife 37 (Fig. 10) thrice. After that, new original
reversible knives must be fitted!
Proceed as follows:
Dismantle the adjustable groove cutter 35 (Fig.
10) from the machine as described in 4.7.
Unscrew the countersunk screws 34 (Fig. 10)
using the torx screw driver.
Clean all parts and the knife chambers of the
plasterboard milling cutter.
Turn or replace the reversible knives 36 and 37.
Fasten the reversible knives with the
countersunk screws and retighten these with the
torx screw driver (4 Nm).
The two parts have been inserted correctly if the rear
of a knife edge is resting against the carrier body and
the countersunk screw can be screwed in that far that
the surface of the countersunk screw is located below
or on the same level as the surface of the reversible
knife (see Fig. 10). The radial blade protrusion of
max. 1.1 mm (3/64 in.) is thus guaranteed.
4.12 Aluminium compound milling cutter
Aluminium compound milling plates
cannot be turned as they are
soldered in. (A blunt tool must be
reground).
5 Operation
5.1 Initial operation
Personnel entrusted to work with the machine must
be made aware of the operating instructions, calling
particular
attention
to
the
chapter
"Safety
instructions".
5.2 Switching on and off
Switching on:
First unlock the switch-on lock
by pressing the locking lever 7 (Fig. 5). Then,
keeping the locking lever depressed, activate
the gearshift lever 8.
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.
In addition, this electronic system reduces the motor
output in case of an overload, i.e. the tool stops.
Switch the machine off then. Then switch the
machine on again and continue sawing at a reduced
feed speed.
The setting wheel 9 (Fig. 3) can be used to adjust the
tool speed in a continuously variable manner between
3600 and 6250 rpm.

Switching off:
To switch off, release the
gearshift lever 8. The built-in automatic brake
limits the slowing time of the tool to approx. 5 s.
The switch-on lock is automatically reactivated
and secures the groove-cutting machine against
accidental switch-on.
