Li-Ion Battery Charge Status Display - Hilti AG 4S-A22 Manual De Instrucciones

3.4 ATC
The power tool is equipped with the ATC (Active Torque Control) quick-acting electronic cut-out.
If the accessory tool sticks or stalls, the power tool will suddenly pivot about its own axis in the opposite
direction. ATC detects this sudden pivoting movement of the power tool and switches the tool off immediately.
For ATC to function correctly, the power tool must be free to pivot.
After an ATC cut-out, switch the power tool off and then on again.
3.5 Temperature-dependent motor protection
The temperature-dependent motor protection system monitors current input and motor temperature and
thus prevents the power tool overheating.
If the motor is overloaded through application of excessive working pressure, the power tool's performance
drops noticeably or it may stall completely.
If the power tool stalls or slows significantly due to overloading, release the pressure applied to the tool and
then allow it to run under no load for approx. 30 seconds.
3.6 Guard with front cover
When grinding with straight grinding discs and cutting with cutting discs in metalworking applications, use
the standard guard with front cover.
3.7 DC-EX 115/4.5" compact dust hood for cutting (accessory)
When cutting mineral materials with diamond cutting discs, use the DC-EX 115/4.5" compact hood.
Use of this guard for working on metal is not permissible.
3.8 DG-EX 115/4.5" dust hood for grinding (accessory)
The grinding system is suitable only for occasional use with diamond cup wheels for grinding mineral
materials.
Use of this guard for working on metal is not permissible.

4 Consumables
Use only synthetic-resin-bonded, fiber-reinforced discs with a maximum Ø of 4.5" (115 mm) approved for a
rotational speed of at least 11500 rpm and a peripheral speed of 262 ft⁄s (80 m/s).
The maximum grinding disc thickness is 1/4" and the maximum cutting disc thickness is 1/8".
ATTENTION! When cutting or slitting with abrasive cutting discs always use the standard guard with
the additional front cover, or a fully enclosing dust hood.
