regulations.
c) If you are in doubt about the effective-
ness of the power outlet's earth/ground
connection, have it checked by a quali-
fied specialist.
d) Avoid body contact with earthed or
en
grounded surfaces,
radiators,
There is an increased risk of electric shock
if your body is earthed or grounded.
e) Do not expose appliances to rain or wet
conditions. Water entering an appliance
will increase the risk of electric shock.
f) Check the appliance's supply cord at
regular intervals and have it replaced at
a Hilti service center if damage is found.
Check extension cords at regular inter-
vals and replace them if found to be dam-
aged.
g) Check the condition of the appliance and
its accessories. Do not operate the ap-
pliance and its accessories if damage is
found, if the appliance is incomplete or
if its controls cannot be operated fault-
lessly.
h) Do not touch the supply cord or
extension cord if they are damaged
while working. Disconnect the supply
cord plug from the power outlet.
Damaged supply cords present a risk of
electric shock.
i) The electric supply cord may be replaced
only with a cord of the type specified in
the operating instructions.
j) Damaged or faulty switches must be re-
placed at a Hilti service center. Do not
use the appliance if it cannot be switched
on and/or off correctly.
k) Have the appliance repaired only by a
trained electrical specialist (Hilti service
center) using genuine Hilti spare parts.
Failure to observe this point may result
in risk of accident to the user.
l) Do not abuse the cord. Never use the
cord for carrying, pulling or unplugging
the appliance. Keep the cord away from
heat, oil, sharp edges or moving parts.
Damaged or entangled cords increase the
risk of electric shock.
m) When operating an electric appliance
outdoors, use only extension cords of a

compliance
with
such as pipes,
ranges and refrigerators.
local
type suitable for outdoor use. Use of a
cord suitable for outdoor use reduces the
risk of electric shock.
n) In case of an interruption in the elec-
tric supply: Switch the appliance off and
unplug the supply cord.
o) Avoid using extension cords with mul-
tiple power outlets and the simultaneous
use of several appliances connected to
one extension cord.
p) Use the electric tool power outlet only for
the purposes described in the operating
instructions.
q) Never spray the top section of the va-
cuum cleaner with water: this presents
an electrical hazard and may damage
the appliance.
r) Connectors on mains power cables,
extension cords or supply cords must
provide protection from sprayed water.
s) Grip the plug when unplugging the supply
cord (do not pull or tug at the supply
cord).
t) Never pull the vacuum cleaner by the
supply cord to a new working position.
u) Never operate the appliance when it is
dirty or wet. Dust (especially dust from
conductive materials) or dampness ad-
hering to the surface of the appliance
may, under unfavorable conditions, lead
to electric shock. Dirty or dusty appli-
ances should thus be checked at a Hilti
service center at regular intervals, espe-
cially if used frequently for working on
conductive materials.
v) Check to ensure that the supply cord
does not lie in a puddle of water.
w) Do not use the power outlet or accessor-
ies when the hands are wet.
5.7 Material picked up
a) Do not use the appliance to pick up flam-
mable or explosive dusts (magnesium
or aluminium dust etc.) or dusts which
present a health hazard.
b) A vacuum cleaner of the dust class M is
suitable for picking up dry, non-flammable
