4.2.4 Sawing and cutting
– Press the handle with the hand grip downwards until
the set depth is reached. Slide the machine forwards.
► Check the diamond cutting blades before use. The
diamond cutting blade(s) must be mounted properly
and must be able to rotate freely. Carry out a test run
for at least 60 seconds without any load. Do not use
diamond cutting blades that are damaged, out-of-ba-
lance, or vibrate. Damaged diamond cutting blades can
rupture and lead to injuries.
4.2.5 Working Advice
► Do not strain the machine so heavily that it comes
to a standstill.
► The machine may only be used for dry cutting.
– Adjust the cutting depth, see section "Pre-selectingthe
Cutting Depth".
– Guide the machine with both handles, applyingmodera-
te feed, suited to the material being worked.
– The machine must always work in an upward grinding
motion. Otherwise, the danger exists of it being pushed
uncontrolled out of the cut.
– After finishing the working procedure, swivel the cutting
unit out of the slot with the machine still running, until
the cutting unit engages in the uppermost position.
– Switch the power tool off.
Do not brake coasting diamond cutting blades by ap-
plying pressure to the side.
► Diamond cutting blades become very hot during
operation; do not touch them until they have co-
oled down.
► Curved cuts are not possible, as the diamond cut-
ting blades could jam in the material.
When cutting especially hard material, e. g., concrete
with high pebble content, the diamond cutting blade
can overheat and become damaged as a result. This
is clearly indicated by circular sparking, rotating with
the diamond cutting blade. In this case, discontinue
the cutting process and allow the diamond cutting
blade to cool by running the machine for a short time at
maximum speed with no load.
Noticeable decreasing work progress and circular spar-
king are indications of a diamond cutting blade that has
become dull. Briefly cutting into abrasive material (e. g.
lime-sand brick) can resharpen the disc again.

5.0 Maintenance and Service
Maintenance and Cleaning
► Before any work on the machine itself, pull the
mains plug.
► For safe and proper working, always keep the ma-
chine and ventilation slots clean.
After finishing work, dismount the clamping fixtures and
clean all clamping parts as well as the protective cover.
When the carbon brushes are worn out, the machine
switches itself off.
The machine must then be sent to an after-sales ser-
vice agent. Addresses are listed in the Section "After-
sales service and customer assistance".
If the machine should fail despite the care taken in
manufacturing and testing procedures, repair should
be carried out by an after-sales service centre for
WOLFF power tools.
In all correspondence and spare parts orders, please
always include the 10-digit article number specified on
the type plate of the machine.
