defective. Have the tool repaired at an authorized Hilti
service center right away.
WARNING
Slits cut in loadbearing walls of buildings or other struc-
tures may influence the statics of the structure, especially
when steel reinforcing bars or load-bearing components
are cut through. Consult the structural engineer, ar-
en
chitect, or person in charge of the building project
before beginning the work.
WARNING
The electric supply voltage must comply with the in-
formation given on the type identification plate on the
power tool. 230 V power tools may also be connected
to a 220 V supply.
WARNING
Always use the side handle with the power tool (use
the hoop handle as an option).
WARNING
Use clamps or a vice to hold the workpiece securely.
WARNING
Breathing protection must be worn if the power tool
is used without a dust extraction system for work that
creates dust.
WARNING
Avoid touching rotating parts. Switch the power tool
on only after bringing it into position at the workpiece.
Touching rotating parts, especially rotating insert tools,
may lead to injury.
CAUTION
The insert tool may get hot during use. Wear protective
gloves when changing insert tools.
CAUTION
In accordance with the applications for which it is de-
signed, the power tool produces a high torque. Always
use the side handle and hold the power tool with both
hands. The user must be prepared for sudden sticking
and stalling of the insert tool.
CAUTION
Working on the material may cause it to splinter. Wear
eye protection and protective gloves. Wear breathing
protection if no dust removal system is used. Splin-
tering material presents a risk of injury to the eyes and
body.
WARNING
Reduce the load on the power tool by avoiding tilting
the disc in the kerf when cutting. The disc or wheel
may otherwise break, or the power tool may kick back or
stall.
30
CAUTION
Improve the blood circulation in your fingers by re-
laxing your hands and exercising your fingers during
breaks between working.
WARNING
Keep inflammable materials away from the working
area.
7.1 Rough grinding
CAUTION
Never use abrasive cutting discs for grinding.
Best results are obtained when the disc maintains an
angle of 5° to 30° with the working surface when grinding.
Move the power tool to and fro while applying moderate
pressure. This will avoid overheating and discoloration of
the workpiece and ensure an even surface finish.
7.2 Cutting
When cutting, apply moderate feed pressure and do not
tilt the power tool or, respectively, the cutting disc (hold
at approx. 90° to the surface being cut). For best results,
start cutting at the smallest cross section when cutting
profiles and square tube.
7.3 Switching on / off without locking the switch
(DEG 125-D or DEG 150-D)
7.3.1 Switching on
1. Plug the supply cord into the power outlet.
2. Slide the on / off switch forward and then press it as
far as it will go.
7.3.2 Switching off

NOTE
If the tool is unplugged from the electric supply while
the on / off switch is locked in the on position and
subsequently plugged back into the electric supply, the
tool will not restart. The switch lock must be released
while the tool is disconnected from the electric supply
before the supply cord is again plugged into the power
outlet.
7.4.1 Switching on and locking the switch
1. Plug the supply cord into the power outlet.
2. Slide the on / off switch forward slightly (3 mm) and,
while pressing it down, slide it further forward until
it locks in position.
