Possible cause
Interruption in the elec-
tric supply.
The electronic restart
interlock is activated
after an interruption in
the electric supply.
The power tool is too
cold.
The gauge (cross sec-
tion) of the extension
cord conductors is inad-
equate.
The voltage provided by
the electric supply is too
low.
The function selector
switch is not engaged or
is in the "Chiseling"
or "Chisel adjust-
ment" position.
The chuck is not pulled
back fully.
The side handle is not
fitted correctly.
Action to be taken
▶ Plug in another electric
tool or appliance
and check whether it
works.
▶ Switch the power tool
off and then on again.
▶ Bring the tip of the drill
bit into contact with
the working surface,
switch the rotary
hammer on and allow
it to run. If necessary,
repeat the procedure
until the hammering
mechanism begins to
operate.
▶ Use an extension cord
with an adequate con-
ductor cross section.
▶ Connect the combi-
hammer to a different
electric supply.
▶ Set the function
selector switch to
the "Hammer drilling"
position
▶ Pull the chuck back
as far as it will go and
remove the accessory
tool.
▶ Release the side
handle and refit it
correctly so that the
clamping band and
side handle engage in
the recess.
