•Do not make any changes, additions or conversions to the Edge coating deleter device. This applies in particular to safety
devices. Unauthorised modifications and alterations to the Edge coating deleter will invalidate the EC declaration of con-
formity issued.
•The operating instructions must be kept with the unit.
•Regularly check the grinding wheel, protective guard and cable for damage. Replace damaged parts immediately!
•The use of the Edge coating deleter in a potentially explosive (ATEX) area is prohibited.
•During operation, never reach into the working area of the Edge coating deleter by hand or with tools; do not bypass pro-
tective devices. There is a risk of injury!
•The operator must ensure that no unauthorised persons are in the working area during operation. There is a risk of injury!
•Device only to be used in flawless condition. There is a risk of injury!

•Any maintenance work must be done in "OFF" position only. Secure the edge coating deleter against unintentional
switching-on before beginning maintenance work.
•Because of dust formation, masks must be worn when using this tool. The operating company is expected to provide a
suitable grinding dust extraction which has to be connected to the suction piece of the protection cover.

The edge coating deleter is a portable, electrically powered grinder which has been developed for the removal of edge
coatings from glass panes.
Mounted on the cover of the angle grinder are adjustable guide rollers, which are used to guide the grinder along the edge of
the glass. The grinding pressure, which is a deciding parameter for the quality of the coating removal, depends on the user
and his care and experience.
The grinding wheels are especially designed to remove coatings from flat glass.
3. Transport, storage and delivery
The Edge coating deleter is delivered assembled in a cardboard box.
Scope of delivery BO 89.110 one Edge coating deleter and one instruction manual
It is essential to check the scope of delivery for completeness and damage. Transport damage must be reported im-
mediately and in writing to the carrier (forwarding agent, railway, etc.).
If there is any damage, the unit must not be used!
Remove all transport locks and packaging materials and take the edge decoating unit out of the packaging.
Be sure to read all operating instructions before use.
Always store the Edge coating deleter in such a way that damage to the grinding wheel is avoided.
Store in a dry and clean place.

4. Handling
First, mount the special grinding wheel between the two flanges according to the manufacturer's (FLEX) instructions. The grin-
ding width is generally 10 mm and is determined by the width of the grinding wheel.
Next, check the gap between the guide rollers and the grinding wheel
and adjust, if necessary. To do this, adjust the roller plate accordingly.
By using the different threaded bore holes, the guide rollers can be ar-
ranged according to individual requirements.
For example, the middle roller is advantageous when grinding a
shaped edge.
Grinding a free shape. The guide roller at the grinding area promo-
tes uniformity of the grinding width along the entire length.
The guide roller plate is swivel-mounted at the cover. This allows the guide rollers to be adjusted according to the diameter of
the grinding wheel.
It is important that the guide rollers be set so that the roller is approx. half covered by the grinding wheel. That way the two lugs
on the cover are prevented from touching the glass.

Next, check the speed of the grinder (preferably 3000 rpm) and
reset at the speed dial, if necessary. The wheels should gene-
rally be used according to the manufacturer's instructions. In
certain cases, when the outer diameter of the grinding wheel
has decreased due to wear, it could be advantageous to use a
different speed.
After having checked the settings and made any necessary ad-
justments, you are ready to plug the power tool in, make a short
test run and then start the actual work.
Put the glass pane onto a felt-covered table and make sure the
glass pane cannot slide away, e.g. by using stopper rails.
Position the glass so that the edge of the first side to be proces-
sed extends slightly (approx. 5-10 mm) over the table edge. The
entire length of the glass pane needs to be free to allow the
guide rollers to be positioned along the edge.
With the guide rollers resting against the edge of the glass, the edge coating deleter is steadily and evenly guided along the
glass. In doing so, it is the manual work of the operator which determines the forward speed as well as the pressure exerted
when removing the coating.
The work efficiency as well as the service life of the grinding wheels depend not only on the type of coating being removed,
but also very much on the manual skill of the operator. Especially when first touching the grinding wheel down onto the glass
there is a high risk of wear and requires some practice before low-wear working skills are mastered.
After the first side has been ground, the other sides are handled in the same way.
