c) 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 (GFCI) with a rating of max. 30 mA
(tripping current). Use of a ground fault circuit
interrupter reduces the risk of electric shock.
d) Use of a ground fault circuit interrupter (GFCI)
with a maximum tripping current of 30 mA is
recommended.
