7 Milling tools
7.1 Choice of cutter and grinding head
According to use and type of application, there are
various types of cutter heads. To achieve optimal
work results, use suitable grinding heads.
Data in the Chart showing speed pre-selection
options are recommended values only; practice
testing should be always performed – see page
19!
7.2 Cutter / Grinding head change
Before putting into operation, check perfect run
of the cutter tool: turn it manually.
Make sure that all screws are tightened up well.
Four screws connecting the fl ange and the head
tool should be well-tightened up: use torque 5
Nm.
Two screws fi xing the position of the head on the
machine should be well-tightened up: use torque
8 Nm.
Do not leave any tools inserted in.
7.3 Replacing Grinding Wheels
WARNING
Risk of accident, electric shock
 Always pull the plug out of the socket before
performing any type of work on the machine.
If teeth of milling rings that are made of hard alloy
are worn, it is possible to replace them.
 By means of turning the knob [1-5] release the
clamping belt to such extent so as it is possible
to move the suction fl ange [1-7].
 Turn the suction fl ange fully counter-clockwise
and pull it downwards.
 Release two bolts [2-1], [2-7] on four axes of
tool carrier using the hexagonal spanner S4.
Now, the milling cutters are easily accessible.
 When replacing milling rings replace also bolts
[2-1], [2-7] and excessive turn retainers [2-
2]. The bolts have been fi xed by light adhesive
agent so as they cannot be loosened by vibra-
tions. Only use originally supplied bolts.
 Firstly, put three milling rings [2-4] onto each
axis, then the washer [2-3]; fasten everything
with the help of excessive turn retainer [2-2]
and bolts [2-1], [2-7]. It is extremely important
that you insert the excessive turn retainer into
corresponding slot [2-5] located in tool carrier
axis. If the excessive turn retainers are not in-
stalled, bolts could be loosened during opera-
tion; this may cause major losses.
 Put on the suction fl ange [2-10] so as sliding
parts [2-8] snap into corresponding slots [2-9]
located on suction fl ange.
 Set the milling depth required and tighten the
clamping belt using the turning knob.
When installing the model with fl at teeth, it is im-
portant that milling rings are installed as shown
in the Fig. [3]; it means that tips must be oriented
in the direction of milling head rotation.
The model with spiked teeth (HW-SZ 12) is used
to remove old layers of paint from concrete or
plasters. The version with fl at teeth (HW-FZ 12)
is used for smoothening of timbering gaps and
for machining of concrete edges.
8 Operation
WARNING
When operating with renovation cutter, you
must use goggles so as you protect your eyes
from fl ying material particles!
Adjustable height of suction fl ange is necessary
to be adapted to mode of use. When removing old
layers of paints, tips of teeth would not overlap
the suction fl ange by more than 1 mm. In the con-
trary, when milling plasters, the milling rings can
overlap by 2 to 4 mm. To adjust the height, slightly
release the clamping belt using the turning knob
[1-5] and turn the suction fl ange [1-7] counter-
clockwise or clockwise. Adjustable range is up to
5.5 mm. The milling depth adjusted can be roughly
read on the scale [1-8]. If height adjustment does
not operate smoothly, we recommend cleaning
the guide surfaces [2-6] and [2-11]. Once the
height is adjusted, fasten tight the clamping belt.
CAUTION
Do not ever operate the machine without suc-
tion fl ange! Only remove it when cleaning the
guide surfaces or when replacing milling rings.
When carrying out these operations, always
remove the plug from wall socket!
The suction fl ange can be also used on machined
area as a holder [1-6]. On principle, the renova-
tion cutter should be applied fl atwise onto the
work piece. In case of fl at surfaces, optimum ad-
th
justment is 6 step of the Electronic.
