Dust extraction
Dust from materials like lead paints, some wood
types and metals may be hazardous to your health.
Skin contact or inhalation of that dust may result in
allergic reactions and/or respiratory illness of the
operator or other personnel in the vicinity.
Specific types of dust (e.g. oak or beech wood) are
carcinogenic, specifically in conjunction with ad-
ditives for wood treatment (chromate, wood pre-
servative). Materials containing asbestos must only
be processed by specialists.
Always use a dust extractor when processing min-
eral substances (filter class "M").
For best results, use the recommended Collomix
high-performance dust extractor with this power
tool. This extractor with filter class "M" is certified
for the extraction of fine particulate.
Ensure sufficient ventilation of the work area.
The use of a respiratory protection mask with filter
class P2 is recommended.
Connection:
Create an air-tight connection between the extrac-
tion hose of the extractor with Ø 35 mm and the
extractor connector on the protective hood.
Comply with the following instructions when
working with the dust extractor:
Only work with the product combination of power
tool and specified diamond cup disk recommend-
ed by Collomix, and the Collomix extractor of class
"M". This will guarantee optimised dust extraction
and work process.
Read the separate operating manual for the extrac-
tor, and take particular note of the cleaning, main-
tenance and filter replacement instructions.
Ensure to empty the dust extractor regularly. Use
the stipulated plastic dust bags to prevent the dust
from entering the environment.
Always wear hearing protection, protective gog-
gles, dust mask and protective gloves while work-
ing.
Operation
Note mains voltage specification! The volt-
age data provided on the type plate must match
the voltage of the power source. 230 V devices can
be operated with 220 V or 240 V power sources.
Switching ON/ OFF
► To switch on the machine, push the ON/ OFF
button forward until it locks into place. Wait
until the machine has run up to full speed.
► To switch off the machine, simply press the
ON/ OFF switch and it will jump back into OFF
position.
Check the cup wheel before use. The cup wheel
must be mounted perfectly and run smoothly. Al-
low the machine to run at idling speed for at least
1 minute before commencing work. Do not use
any damaged, non-round or vibrating grinding
cups. Check for correct mounting of the grinding
disk or replace it if you detect strong vibrations.
Please contact a service representative immedi-
ately if your adjustments do not result in an im-
provement.
Operating instructions
First switch on the device, then place the cup wheel
fully and evenly on the surface to be treated. Be
careful not to tilt the tool.
Always hold the device with both hands. In con-
tinuous operation the device will continue to run
when it is torn from your hands.
Work in straight lines or with a circular motion. The
best results are achieved without excessive down-
pressure onto the area to be processed. Do not
push down on the grinder, as this might cause the
machine to stop.
Do not touch the grinding cup until it has cooled
down. The grinding cup on a concrete grinder can
become very hot during operation.
See Fig. A1 - A3
Open one segment on the protective hood for
grinding along wall edges. This will allow the pro-
cessing of areas that would otherwise be inacces-
sible.
Press the hood segment you wish to open slightly
forward and push it to the side. The segment is
spring-mounted.
To close the segment, simply push it back into
place.
Before opening the hood segment, stop the
machine and pull the cable.
All other grinding tasks must only be carried out
with the protective hood fully closed.
