Safety precautions
SV00068GB 27
4.10 Cutting masonry concrete, asbestos or asphalt
ATTENTION!
Always wear approved respiratory protection!
Asbestos and other materials that can release toxic substances
may be cut only after notifying the proper authorities and under
their supervision or that of a person appointed by them. When
cutting prestressed and reinforced concrete piles, follow the
instructions and standards of the responsible authorities or the
builder of the structural member. Reinforcement rods must be cut
in the prescribed sequence and in accordance with applicable
safety regulations.
NOTE!
Mortar, stone, and concrete develop large quantities of dust during
cutting. To increase the lifetime of the cutting blade (by cooling), to
improve visibility, and to avoid excessive dust creation, we strongly
recommend wet cutting instead of dry cutting.
In wet cutting, the blade is watered at an equal rate on both sides by a
trickle of water. WACKER offers the right accessories for all wet cutting
applications (see also “SPECIAL ACCESSORIES“).
4.10.1 Remove foreign objects such as sand, stones and nails found within
the working area.
Caution: Watch out for electric wires and cables!
The rapid rotation of the cutting blade at the point of contact
throws fragments out of the cut groove at high speed. For your
safety, swing the protective hood down as far as possible behind
the cut (23), so that material fragments are thrown forward, away
from the operator.
4.10.2 Mark the cut, and then make a groove about 5 mm deep (just under
0,2“) along the entire length of the planned cut. This groove will then
guide the cut-off saw accurately guring the actual cutoff.
