Operation; Rough Grinding - Hilti DAG 115-S Manual De Instrucciones

7. Before switching on, check that the cutting/grinding
tool is fitted correctly and that it is free to rotate.
8. To remove the disc from the power tool, follow the
instructions for fitting the disc but carry out the steps
in the reverse order.
6.4 Rotating the gearing section 3
NOTE
To allow the power tool to be used safely and without
fatigue in all positions (e.g. on / off switch facing upwards),

7 Operation

DANGER
Wear ear protectors. Exposure to noise can cause hear-
ing loss.
WARNING
Test new cutting or grinding discs by allowing them
to run at maximum speed in a protected area for at
least 60 seconds.
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-
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.
WARNING
Never use the power tool without the guard.
CAUTION
Use clamps or a vice to hold the workpiece securely.
WARNING
Cutting or grinding may cause splintering of the material.
Wear eye protection.
CAUTION
Breathing protection must be worn if the power tool
is used without a dust removal system for work that
creates dust.
the gearing section can be rotated to one of four positions
at 90° intervals.
1. Disconnect the supply cord plug from the power
outlet.
2. Clean the power tool.
3. Remove the side handle from the power tool.
4. Remove the four screws from the gearing section.
5. Rotate the gearing section to the desired position
without pulling it away from the power tool.
6. Secure the gearing section by inserting and tighten-
ing the four screws.
7. Fit the side handle.
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.
WARNING
Reduce the load on the power tool by avoiding tilt-
ing the disc in the kerf when cutting. The disc may
otherwise break, or the power tool may kick back or stall.
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 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.
