There is a risk of clothing and hair getting entangled. There is a risk of
hands being crushed. Serious injury may result.
To prevent dust formation, always have the coolant tap on while dressing and direct the coolant hose at the grinding wheels.
Never dress with mounted knives.
Serious cutting injuries may result.
CAUTION
7.3 Dressing the front / rear ceramic grinding wheels
If the front grinding wheel is running out of true
or is loaded, it must be dressed.
Set the grinding discs to a comfortable position
(approx. 34° – see Chapter 7.5).
Change to settings via the main menu “F5 Settings” (3-8/15).
Switch on the front grinding wheel. To do so,
press “Front Grinding Wheel On / Off” (7-21/1) on
the touch panel.
ATTENTION
Turn the “Setting Mode” key switch
(3-7/5) to position “1”.
Insert the deburring lever (7-22/1) as far as it will
go into the relevant bushing. Move the dressing
diamond (7-22/2) with the deburring lever evenly
over the grinding wheel, which is switched on.
The dressing diamond is fed by rotating the adjusting nut (7-22/3) in clockwise direction.

by turning it counter-clockwise.
Remove the front or rear grinding wheel and also
the connection flange (7-26/1) if necessary and
mount the new grinding wheel in the reverse
order.
If the grinding wheel is half-worn, mount the intermediate flange (7-26/1) with an M8x40 screw.

The machine has a network connection which can
be used to establish a direct link between
the machine and KNECHT. The connection allows
the display screen content on the grinding machine to be transmitted. In this way, the manufacturer's technicians can perform a diagnosis of the
machine, change software settings and install or
edit new grinding programs.
“Team Viewer”, the program pre-installed on your
machine, is required in order to set up the internet
connection. An active internet connection must be
available.

9. Care and maintenance
For all work on the grinding machine, the locally applicable safety and
accident prevention regulations as well as instructions in the “Safety”
and “Important notes” section of the operating instructions must be
observed.
CAUTION
9.1 Coolant
The cooling water has to be replaced every week
and the water tray must be cleaned.
The water trough must always be filled with water
up to 3 cm below the rim. The water trough can
be pulled out in front for filling and cleaning.
The pump (9-1/1) including the guard can be
removed by loosening and removing the star
handles (9-1/2).
9.2 Lubricate cross table
Place grease gun on the lubrication points and
lubricate the cross table.
We recommend “OEST Multi-Purpose Grease L2”
or a similar customary make.
Press one stroke of grease into the lubrication
point once a month

9.3 Clean grinding machine
After grinding and / or dressing work, the grinding machine must be cleaned with a moist rag or a
wet vacuum cleaner. Rub acid-free oil into the grinding machine. Clean the window with window
cleaning agent.
ATTENTION
Do not spray-wash the grinding machine with
water. This can damage the machine.
9.4 Other lubrication points
Press one round of grease into the lubrication
points at the marked places once a month using
the grease gun. Grease the spindle (9-3/1) once
every month.
