Disassembling the impact grinding head:
Before disassembling the head of the mill, the mill itself must first cool
down as the grinding chamber and the beater rotor cannot detached
otherwise.
The power supply plug must be disconnected before disassambly. After
the door is openend the countersunk screw Pos. P15 is loosened by
means of Allen wrench. For this the shaft is blocked by pressing the pin
Pos. A15. If the hexagon socket is dirty then it must be cleaned by
means of a brush. After the countersunk screw and the disk Pos. P11
are removed the hammer rotor Pos. P13 is taken off and the fitting key
Pos. A7 removed. Now the three screw mountings Pos. P5 are loose-
ned by means of a fork wrench and the grinding chamber is rotated in a
clockwise direction and taken off.
Cutting mill:
Assembling the cutting mill head:
Caution: The blades on the rotor and in the grinding chamber have
sharp edges. Both parts should only be handled when wearing protec-
tive gloves.
The ON/OFF switch Pos. A13 must be to zero and the power supply
plugs must have been disconnected out before beginning assembly of
the cutting-grinding head.
First the three threaded bolts Pos. S12 are screwed out to the same
hight (distance between hexagon of the bolt and the flat surface on the
grinding head is appoximately 2mm, this corresponds to two turns).
Make sure that the flange piece on the drive and on the head are clean
and free of dust. Abrading both fitting parts with a slightly oiled rag faci-
litates assambly. The head is now pushed onto the drive, while making
certain that the parts do not jam. The threaded bolt ends must fit into
the drillings of the transmission cover. Thus the head has be rotated
slightly in a clockwise direction. After the bolts are fitted in the head is
turned until it is stopped by the bolts and so that the head now stands
upright.
Now close and clock the grindinding chamber door with the operating
knob Pos. S9 (3 to 5 revolutions are sufficient). This ensures that the
20
grinding chamber is optimally aligned so that the door can be easily
openend and closed later.
Now the screw mountings are tightened with the fork wrench provided.
Make certain that the pins are tightened toward the head.
NOTE: Tighten the pins evenly (see Fig. 1) !
Now the hammer rotor Pos. S20 can be installed. For this the fitting key
Pos. A7 is first inserted into the groove of the drive shaft Pos. G6, make
certain that the groove is free from dirt and dust here as well. The rotor
is pushed onto the drive shaft as shown in Fig. 2, fastened with the disk
Pos. S22 and the cheese head screw Pos. S21. The countersunk screw
is tightened with the Allen wrench provided, while the pin Pos. A15 is
pressed. The pressed pin prevents the shaft from slipping while the
countersunk screw is tightened. The pin engages in two positions.
These can be found by pressing the pin and at the same time turning
the shaft (simply turn the rotor with the tool until the pin engages).
After tightening the cheese head srew pin Pos. A15 release
and turn the hammer rotor once (360°) using the Allen
wrench. The rotor may not touch. Repeat assembly if neces-
Note: sary.
Now the filter Pos. Z1 that is suitable for the grinding procedure can be
inserted; to do so the filter is pushed into the grinding chamber from
the front. The filter and the filter holder surface in the grinding cham-
ber must be free from dirt and dust.
Now the grinding chamber door can be closed and locked with the ope-
rating knob Pos. S9. The screw mounting of the operating knob is scr-
ewed in by pressing and twisting it into the internal thread on the drive
cover. The first turns are easy, if turning becomes difficult then the door
may be closed, but the safety switch is not yetunlocked. Continue tur-
ning until stop (approximately two revolutions), only then is the safety
switch unlocked and the mill ready to start.
