Hilti VC 20-U Mode D'emploi page 27

Damaged or faulty switches must be replaced at
j)
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 elec-
trical 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 car-
rying, pulling or unplugging the appliance. Keep
the cord away from heat, oil, sharp edges or mov-
ing parts. Damaged or entangled cords increase the
risk of electric shock.
m) When operating an electric appliance outdoors,
use only extension cords of a 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 electric supply:
Switch the appliance off and unplug the supply
cord.
o) Avoid using extension cords with multiple power
outlets and the simultaneous use of several ap-
pliances 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 vacuum 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).
Never pull the vacuum cleaner by the supply cord
t)
to a new working position.
u) Never operate the appliance when it is dirty or
wet. Dust (especially dust from conductive ma-
terials) or dampness adhering to the surface of
the appliance may, under unfavorable conditions,
lead to electric shock. Dirty or dusty appliances
should thus be checked at a Hilti service center
at regular intervals, especially 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 accessories when
the hands are wet.
5.7 Material picked up
a) Do not use the appliance to pick up flammable
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 dusts, wood chips or
shavings and hazardous substances with an expos-
ure limit value of ≧0.1mg/m³. The vacuum cleaner
must be equipped with a filter suitable for the
hazard classification of the dusts to be picked up.
c) Do not use the appliance to pick up flammable,
explosive or aggressive liquids (coolants and lub-
ricants, gasoline, solvents, acids (pH<5), alkalis
(pH>12.5) etc.)
d) Switch the appliance off immediately if foam or
liquids escape from it.
e) Avoid contact with alkaline or acidic liquids. If
contact accidentally occurs, flush with water. In
the event of the liquid coming into contact with
the eyes, rinse the eyes with plenty of water and
consult a doctor.
f) Wear protective gloves when using the vacuum
cleaner to pick up hot materials with a max. tem-
perature of 60°C.
g) Do not pick up objects or materials that could
cause injury by piercing through the dust bag
(e.g. pointed or sharp objects).
5.8 Thermal
Do not use the vacuum cleaner to pick up hot mater-
ials with a temperature of over 60°C (glowing cigar-
ettes, hot ash, etc.).
5.9 Personal protective equipment
a) The user and any other persons in the vicinity
must wear suitable eye protection, a hard hat,
ear protection, protective gloves, safety footwear
and respiratory protection while the appliance is
in use or during servicing.
b) When working with mineral drilling slurry, wear
protective clothing and avoid skin contact with
the slurry (pH>9: caustic).
