Switching On/Off - Hilti DAG 450-S Mode D'emploi

WARNING
Always use the side handle with the power tool.
WARNING
Never use the power tool without the guard.
en
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.
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 an-
gle of 15° to 40° with the working surface when grinding.
Move the power tool to and fro while applying moderate
10
pressure. This will avoid overheating and discoloration of
the workpiece and ensure an even surface finish.
7.2 Abrasive flap discs
Abrasive flap discs can be used for working on curved
surfaces and profiles. Abrasive flap discs last consider-
ably longer than flexible grinding discs, are less noisy and
get less hot.
7.3 Cutting
Apply only moderate pressure and do not tilt the power
tool or cutting disc when cutting. For best results, start
cutting at the smallest cross section when cutting profiles
and square tube.
7.4 Switching on / off
In the event of motor overload due to application of
excessive pressure to the disc, performance will drop
noticeably or the power tool may stop running (avoid
stalling the power tool in this way). Permissible overload
cannot be given as a specific value as it depends on the
temperature of the motor . If the power tool has been
overloaded, release the pressure applied and then allow
it to run under no load for approx. 30 seconds.
7.4.1 Switching on with the on / off switch
(DAG 450‑S)

switch jumps back to the off-position.
7.4.3 Switching on with the hold-to-run switch
(DAG 450‑D) 5
The hold-to-run switch with built-in safety interlock en-
ables the user to check the switch function and prevents
inadvertent starting of the power tool.
1. Press the safety interlock to unlock the hold-to-run
switch.
2. Press the hold-to-run switch fully.
7.4.4 Switching off with the hold-to-run switch

lock returns automatically to the locked position.
