Operation
WARNING
Always make sure that the tool attachment is fitted cor-
rectly!
CAUTION
Keep your hands away from the tool attachment when
the product is in operation.
• Always hold the product tight with both hands
during work. Make sure that you have a secure foot-
ing.
• Ensure that other people remain at a safe distance
from your workspace. Anyone who enters the
workspace must wear personal protective equip-
ment. Fragments of the workpiece or broken accesso-
ry tools can fly off and cause injury – even outside the
immediate working area.
Note:
Slots in load-bearing walls are subject to the DIN 1053
Part 1 standard or country-specific specifications. These
regulations must be observed at all times. Consult the re-
sponsible structural engineer, architect or site manager
before starting work.

Switching the product on/off (Fig. 6)
Switching on
1. Reach around the rear handle (1).
2. Press and hold the switch-on lock (11) with your index
finger.
3. Press and hold the on/off switch (10).
4. The product starts.
After switching on, wait until the product has reached its
maximum speed. Only then should you start working.
After the product has started, you can release the switch-
on interlock again.
Switching off
1. To switch off, release the on/off switch (10) and the
switch-on lock (11).
CAUTION
After switching off, the product will run on. Wait until the
product has come to a complete stop.
9.2
Test run
Before the first work and after each tool attachment
change, carry out a test run without load. Switch off the
product immediately if the tool attachment runs out of
round, there is considerable vibration or abnormal noises
are heard.
9.3
Overload protection
In the event of overloading, the product will switch itself
off. After a cool-down period (time varies), the product
can be switched back on again.
10 Working instructions
ATTENTION
Use a pipe detector to check walls and walls for hid-
den electricity, gas and water pipes before working
with the product.
Curved cuts are not possible, as the insert tool would oth-
erwise jam in the workpiece.
Protect the cutting disc from impact, shock and grease.
Do not subject the cutting disc to lateral pressure.
Do not stop the cutting discs from running out by pressing
against them from the side.
10.1
Working with the wall chaser
(Fig. 7-9)
Notes:
• Always hold the product tight with both hands
during work. Make sure that you have a secure footing.
• Grooves of greater depth in hard material (e.g. con-
crete) cannot be cut in a single pass.
• When cutting particularly hard materials, e.g. concrete
with a high silica content, the cutting disc can over-
heat and be damaged as a result. A ring of sparks
running around the cutting disc clearly indicates this.
In this case, interrupt the cutting process and allow
the cutting disc to idle at maximum speed for a short
time in order to cool it down.
ATTENTION
Use a pipe detector to check walls and walls for hid-
den electricity, gas and water pipes before working
with the product.
WARNING
Never try to pull the cutting wheel out of the
cut while it is still running, otherwise kick-
back may occur.
1. Always hold the product by the rear (1) and front han-
dle (4).
2. Place the product switched on (with running cutting
discs) with the front support roller (5) on the masonry.
3. Plunge the cutting discs (6) into the masonry until the
set cutting depth is reached and the rear support roll-
ers (5) are also in contact with the masonry.
4. Push the product through the material to be pro-
cessed in the prescribed direction.
Pay attention to the markings (direction of rotation of
the cutting disc
uct
Otherwise the cutting disc (6) may get caught, jump
out of the workpiece or cause a kickback.
5. When you have completed the groove, switch off the
product and hold it still until the cutting disc (6) has
come to a standstill.
6. Remove the product from the cut and place it to the
side.
7. Remove the remaining bar with a stripping tool*.
