ENGLISH – ORIGINAL INSTRUCTIONS
After mounting the diamond grinding wheels and before
switching on, check that the diamond grinding wheels are
correctly mounted and that they can turn freely. Make sure
that the diamond grinding wheels don’t graze against the
guard and extraction hood or other parts.
OPERATING INSTRUCTIONS
Verify the switch [8] actuates properly and returns
to the 0-position when the rear of the switch lever
is pressed, before plugging in the power tools.
Set grinding depth in advance
Pull the mains plug of the power tool from the
socket, before any work on the machine itself!
• Loosen the depth locking [14] so it can move in its run-
way.
• Move the depth locking to its lowest position.
• Close the inner guard [3] until the diamond grinding
wheels stick out the requested amount of millimeters (x)
from the guard and extraction hood. By closing the inner
guard the depth locking will move upwards. If the inner
guard passes the requested position the depth locking
must be moved down again. Ignoring this will result in a
unrequested slot depth.
• Tighten the depth locking. The inner guard will swivel to
its lowest position when unleashed.
The graduated scale on the cover of the guard and ex-
traction hood is indicative and therefore not foreseen of a
calibration. When the segments wear down this declines
the grinding depth.

Usage
Connect the power tool to an power supply with the same
current as stated on the nameplate.
Connect and switch on the dust extractor.
To start the power tool, slide the ON/OFF-switch [8] to-
wards the front. For continuous operation, press the front
of the switch to lock it.
To stop the power tool, press the rear of the switch so it
returns to the OFF-position.
Check diamond grinding wheels before using. The dia-
mond grinding wheels must be mounted properly and be
able to move freely. Carry out a test run for at least one
minute with no load. Do not use damaged, out-of-centre
or vibrating diamond grinding wheels. Damaged diamond
grinding wheels can burst and cause injuries.
When operating the power tool, hold it fi rmly with both
hands.
• Set the requested grinding depth. See section “Set grin-
ding depth in advance”. To compensate inaccuracies that
occur when breaking the fi n away, the grinding depth
must be set approx. 3mm deeper than the requested slot
depth.
• Place the power tool with the rollers on the surface to
be grinded.
• Switch the power tool on.
• Slowly bring the grinding unit into the material.
• Move the power tool applying a moderate feed, suited to
the material being grinded.
• The power tool must be guided in a up grinding motion.
Otherwise the danger exists that the grinding unit is pu-
shed uncontrolled out of the cut. Guide the power tool in
direction of the arrow (A).
• Vertical slots can easily be grinded by pulling the power
tool from top to bottom.
• At the ending of the grinding procedure swivel the grin-
ding unit out of the material, when the power tool is still
running.
• Switch the power tool off .
Do not slow down freewheeling diamond grinding wheels
applying sideward pressure.
Diamond grinding wheels may become very hot while
operating. Don’t touch the diamond grinding wheels
before they cooled down.
