Action to be taken
▶ Plug in another electric
tool or appliance
and check whether it
works.
▶ Apply a load to
the generator by
connecting a second
power consumer (e.g.
worklight). Switch the
tool off and then on
again.
▶ Fit the detachable
supply cord to the
power tool correctly.
▶ Have the product
repaired only by Hilti
Service.
▶ Use a different power
outlet. Check the
electric supply.
▶ Allow the tool to cool
down. Clean the
air vents. Running
under no load is still
possible.
▶ Bring the tip of the
accessory tool into
contact with the
working surface,
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
gauge.
