• Unscrew the wing screw 14, remove the nut 23 and
the pointer 24, and then move the base plate 16 (see
fig. 2.1).
• Remove the bolts 25 with a Allen key with handle 21
and remove the front cover 26 (see. fig. 2.2).
• Press and hold the spindle lock 2, then with the
flange wrench 20 unscrew the external flange 27 (see�
fig. 3.1). Note: the external flange 27 has a left-hand
thread.
• If during the operation, the external flange 27 has got
too tight, it is recommended to use a Allen key 19 (see
fig. 3.2) to hold the spindle 28� Insert the Allen key 19 into
the axial hole of the spindle 28 and holding it in the fixed
position, unscrew the external flange 27 with the flange
wrench 20 (see. fig. 3.2). Note: the external flange 27
has a left-hand thread.
• Remove from the spindle 28: diamond cutting
disc 18, distance washers 29, diamond cutting disc 18
and internal flange 30 (see. fig. 4).
• Clean all parts with a soft brush and install on the
spindle 28: internal flange 30, diamond cutting disc 18,
distance washers 29, diamond cutting disc 18� Screw
by hand the external flange 27 onto the threaded end
of the spindle 28�
• When installing parts on the spindle 28, you can
change the width of the cut slot by changing the quan-
tity of the distance washers 29 installed between the
diamond cutting discs 18 (see fig. 8).
Attention! observe the following rules during in-
stallation:
• follow the mounting sequence (see fig. 4, 8);
• do not allow distortion of the parts during instal-
lation;
• when installing the diamond cutting discs 18,
make sure that the diameter of their bores corre-
sponds to the diameter of the neck of the internal
flange 30;
• the direction of the arrow on the diamond cutting
discs 18 must always coincide with the direction of
the arrow on the front cover 26;
• Note: regardless of the width of the cut slot, al-
ways install all distance plates 29 (only the order
of their installation changes), otherwise fixing of
the diamond cutting discs 18 will not be ensured;
• at least one distance washer 29 must always be
installed between the diamond cutting discs 18�
• Holding the spindle 28 in the fixed position, using
one of the methods described above, tighten the ex-
ternal flange 27 with the help of the flange wrench 20
(see fig. 3).
• Install the front cover 26 and tighten the bolts 25 with
the Allen key with handle 21 (see. fig. 2.2).
• Return the base plate 16 to its initial position, set the
pointer 24, the nut 23 and screw in the wing screw 14
(see fig. 2.1).
Incomplete disassembly (see fig. 5-7, 8)
Figures 5-7 show the process of incomplete dis-
assembly. In this case, the front cover 26 is not
removed, and all assembly operations are carried
out through a special hole in the front cover 26.
This speeds up the process of replacing the dia-
mond cutting discs 18, as well as setting the width
of the cut slot.
• Unscrew the wing screw 14, remove the nut 23 and
the pointer 24, and then move the base plate 16 (see
fig. 5.1).
• Loosen the wing screw 12 and move the cover 13
upwards, as shown in figure 5.2.
• Press and hold the spindle lock 2, then with the flange
wrench 20 unscrew the external flange 27 (see. fig. 6.1).
Note: the external flange 27 has a left-hand thread.
• If during the operation, the external flange 27 has got
too tight, it is recommended to use a Allen key 19 (see
fig. 6.2) to hold the spindle 28� Insert the Allen key 19 into

position, unscrew the external flange 27 with the flange
wrench 20 (see. fig. 6.2). Note: the external flange 27
has a left-hand thread.
• Remove from the spindle 28: diamond cutting
disc 18, distance washers 29, diamond cutting disc 18
and internal flange 30 (see. fig. 7).
• Clean all parts with a soft brush and install on the
spindle 28: internal flange 30, diamond cutting disc 18,
distance washers 29, diamond cutting disc 18� Screw
by hand the external flange 27 onto the threaded end
of the spindle 28�

change the width of the cut slot by changing the quan-
tity of the distance washers 29 installed between the

flange 27 with the help of the flange wrench 20 (see fig. 6).
• Move the cover 26 down and tighten the wing
screw 12 (see. fig. 5.2).
• Return the base plate 16 to its initial position, set the
pointer 24, the nut 23 and screw in the wing screw 14
(see fig. 5.1).
