2 Description
2.1 Use of the product as directed
The machine is intended for hand-held or walk-behind
use for dry or wet cutting of asphalt and mineral or metallic
construction materials using abrasive or diamond cutting
discs.
To reduce the amount of dust produced when cutting,
we recommend use of the wet cutting method.
The working environment may be as follows: construction
site, workshop, renovation, conversion or new construc-
tion.
To avoid the risk of injury, use only genuine Hilti acces-
sories and cutting tools.
Observe the safety rules and operating instructions for
the accessories used.
Working on materials hazardous to the health (e.g. as-
bestos) is not permissible.
Observe the information printed in the operating instruc-
tions concerning operation, care and maintenance.
Nationally applicable industrial safety regulations must
be observed.
The machine is designed for professional use and may
be operated, serviced and maintained only by trained,
authorized personnel. This personnel must be informed
of any special hazards that may be encountered. The
machine and its ancillary equipment may present hazards
when used incorrectly by untrained personnel or when
used not as directed.
Take the influences of the surrounding area into account.
Do not use the power tool or appliance where there is a
risk of fire or explosion.
Modification of the machine or tampering with its parts is
not permissible.
Don’t work in closed, poorly ventilated rooms.

2.3 Abrasive cutting discs for hand-guided
gasoline-powered cut-off saws
Abrasive cutting discs for gasoline-powered cut-off saws
are composed of synthetic-resin-bonded abrasive gran-
ulate. These cutting discs feature fabric or fiber rein-
forcement which improves their strength, toughness and
breakage resistance.
NOTE
Abrasive cutting discs for gasoline-powered cut-off saws
are used mainly for cutting ferrous and non-ferrous met-
als.
NOTE
Various grit types such as aluminum oxide, silicon car-
bide, zirconium, etc., with a different bonding material
(matrix) or matrix hardness, are available depending on
the construction material to be cut.
2.4 Diamond cutting discs for hand-guided
gasoline-powered cut-off saws
Diamond cutting discs for gasoline-powered cut-off saws
consist of a steel core (disc) with diamond segments
(metallically bonded industrial diamonds).
NOTE
Segmented diamond cutting discs or those with a con-
tinuous cutting face are mainly used for cutting asphalt
and mineral construction materials.
2.5 Cutting disc specifications
With the DSH 700-12" use only diamond discs or
synthetic-resin-bonded fiber-reinforced cutting discs
with a diameter of 12" and a permissible peripheral
speed of at least 80m/sec. With the DSH 700-14",
DSH 900-14" and DSH 900-16" use only diamond
discs or synthetic-resin-bonded fiber-reinforced cutting
discs with a diameter of 14" or, respectively, 16" (DSH
900-16") and a permissible peripheral speed of at least
100m/sec. The cutting disc manufacturer’s instructions
on fitting and using the discs must also be observed.
2.6 Recommendations for use
We recommend that the workpiece is not cut through in
a single operation. Advance to the required depth of cut
by making several to-and-fro movements.
To avoid damaging the diamond cutting disc when dry
cutting, lift the blade out of the cut for approx. 10 seconds
every 30 to 60 seconds while the machine is still running.
To reduce the amount of dust produced when cutting,
we recommend use of the wet cutting method.
