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 flange and the head
tool should be well-tightened up: use torque 5 Nm.
Two screws fixing the position of the head on the
machine should be well-tightened up: use torque
8 Nm.
Do not leave any tools inserted in.
Replacing Grinding Wheels
Prior to milling ring replacement always
remove the plug from wall socket!
Prior to adjusting milling depth always
remove the plug from wall socket!
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 flange (1.7). Turn the suction
flange fully counter-clockwise and pull it down-
wards. Release two bolts (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) and excessive turn retainers (2.2). The bolts
have been fixed by light adhesive agent so as
they cannot be loosened by vibrations. 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). 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 installed, bolts could be loosened during
operation; this may cause major losses. Put on
the suction flange (2.10) so as sliding parts (2.8)
snap into corresponding slots (2.9) located on
suction flange. Set the milling depth required and
tighten the clamping belt using the turning knob.
When installing the model with flat teeth, it is
important 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 (HM-SZ) is used to
remove old layers of paint from concrete or
plasters. The version with flat teeth (HM-FZ) is
used for smoothening of timbering gaps and for
machining of concrete edges.

Caution: During work, inspect whether milling
rings still freely rotate on axes. If it is not the case,
e.g. due to accumulated dust; it is necessary to
remove it from the milling head. For this reason
the machine should not be operated without
suction system connected!
Work with renovation cutter
When operating with renovation cutter,
you must use goggles so as you protect
your eyes from flying material particles.
Adjustable height of suction flange is necessary
to be adapted to mode of use. When removing
old layers of paints, tips of teeth would not over-
lap the suction flange by more than 1 mm. In the
contrary, 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 flange (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 adjust-
ment 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 with-
out suction flange! Only remove it when cleaning
the guide surfaces or when replacing milling rings.
When carrying out these operations, always re-
move the plug from wall socket!
The suction flange can be also used on machined
area as a holder (1.6). On principle, the renova-
tion cutter should be applied flatwise onto the
work piece. In case of flat surfaces, optimum
adjustment is 6

Suction system
To ensure the operability of suction system, put
the hose (36 mm diameter) of some PROTOOL
brand vacuum cleaner onto the hose adaptor (1.4).
