Before Use; Operation - Hilti TE 50 Original Operating Instructions

d) When working outdoors with an electric tool
check to ensure that the tool is connected to the
electric supply by way of a ground fault circuit
interrupter (RCD) with a rating of max. 30 mA
(tripping current). Use of a ground fault circuit
interrupter reduces the risk of electric shock.
e) Use of a ground fault circuit interrupter (RCD
residual current device) with a maximum tripping
current of 30 mA is recommended.
f) In case of an interruption in the electric supply:
Switch the power tool off and unplug the supply
cord. This will prevent accidental restarting when the
electric power returns.
5.3.4 Work area safety
a) Ensure that the workplace is well lit.
b) Ensure that the workplace is well ventilated. Ex-
posure to dust at a poorly ventilated workplace may
result in damage to the health.
