Possible cause
Interruption in the elec-
tric supply.
The generator is in sleep
mode.
The electronic restart
interlock is activated
after an interruption in
the electric supply.
The carbon brushes are
worn.
The power tool is too
cold.
The extension cord is
too long or the conduc-
tor cross-section is in-
adequate.
The control switch is not
fully pressed.
Action to be taken
▶ Plug in another electric
tool or appliance

worklight). Switch the
tool off and then on
again.

▶ Have checked, and if
necessary replaced,
by a trained electrical
specialist.
▶ Bring the tip of the
accessory tool into
contact with the

switch the power
tool on and allow it
to run. If necessary,
repeat the procedure
until the hammering
mechanism begins to
operate.
▶ Use an extension
cord of an approved
length and / or of
adequate conductor
cross-section.
▶ Press the control
switch as far as it will
go.
