injury. KEEP THESE INSTRUCTIONS IN A SAFE PLACE.
2.2.2 General safety instructions
In addition to the safety instructions given in the various sections of these operating
instructions, the following points must be strictly observed at all times.
▶ Read all the instructions. Failure to follow all the instructions listed below may result
in electric shock, fire and/or serious injury.
▶ If the appliance is used in conjunction with an electric tool, read and follow the
operating instructions for the electric tool and all the warnings.
▶ Modification of the appliance is not permitted.
▶ Use the right appliance for the job. Do not use the appliance for purposes for
which it was not intended. Use it only as directed and when in faultless condition.
▶ Before beginning work with the appliance, find out how to operate it correctly
and about any hazards associated with the materials it will be picking up and
how these materials can be disposed of.
▶ Take the influences of the surrounding area into account. Do not use the
appliance where there is a risk of fire or explosion.
▶ The appliance may only be used by persons who are familiar with it, have been
trained on how to use it safely and who understand the resulting hazards. The
appliance is not intended for use by children.
▶ Store appliances in a secure place when not in use. When not in use, appliances
must be stored in a dry, high place or locked away out of reach of children.
2.2.3 Personal safety
▶ Stay alert, watch what you are doing and use common sense when working with
the product. Do not use the vacuum cleaner while you are tired or under the
influence of drugs, alcohol or medication. A moment of inattention while operating
the appliance may result in serious personal injury.
▶ The user and any other persons in the vicinity must wear suitable eye protection,
a hard hat, ear protection, protective gloves, safety footwear and breathing
3
protection while the appliance is in use or while maintenance work on it is being
carried out.
▶ Engage the wheel brakes so that the vacuum cleaner stands securely. If the
wheel brakes are disengaged the vacuum cleaner may run away out of control.
▶ If devices are provided for the connection of dust extraction and collection
facilities, ensure these are connected and properly used. Use of a vacuum cleaner
can reduce dust-related hazards.
2.2.4 Use and care of the appliance
▶ Never leave the appliance unattended.
▶ Do not deactivate the filter cleaning system when picking up hazardous dusts,
especially when the appliance is used in conjunction with electric tools that
generate dust.
▶ Protect the appliance from frost.
▶ Clean the water level limiting device regularly with a brush, in accordance with
the instructions, and check it for signs of damage.
▶ When fitting the top section of the vacuum cleaner, take care to avoid pinching
your fingers or damaging the supply cord. This presents a risk of injury or damage.
▶ Check the appliance and its accessories for any damage. Guards, safety devices
and any slightly damaged parts must be checked carefully to ensure that they
function faultlessly and as intended. Check that moving parts function faultlessly,
without sticking, and that no parts are damaged. In order to ensure faultless
operation of the appliance, all parts must be fitted correctly and must meet the
necessary requirements.
▶ Have the appliance serviced by a qualified repair person using only genuine Hilti
spare parts. The safety of the appliance can thus be maintained.
▶ Always unplug the supply cord from the power outlet when the appliance is not
in use (during breaks), before cleaning and maintenance and before changing
the filter or accessories. This preventive safety measure reduces the risk of starting
the appliance accidentally.
▶ Never pull the vacuum cleaner by the supply cord to a new working position. Do
not run the wheels of the vacuum cleaner over the supply cord.
▶ Do not transport the appliance by crane.
2.2.5 Electrical safety
▶ The plug on the supply cord of the appliance must match the outlet. Do not
change the plug in any way. Do not use adapter plugs with earthed (grounded)
appliances. Unmodified plugs and matching outlets reduce risk of electric shock.
▶ Insert the plug in a suitable earthed/grounded power outlet which has been
correctly and safely installed and is in compliance with local regulations. If
you are in doubt about the effectiveness of the power outlet’s earth/ground
connection, have it checked by a qualified specialist.
▶ Avoid body contact with earthed or grounded surfaces such as pipes, radiators,
cookers, stoves and refrigerators. There is an increased risk of electric shock if your
body is grounded.
▶ Do not expose the appliance to rain or wet conditions. Water entering an electric
appliance will increase the risk of electric shock.
▶ Check to ensure that the supply cord does not lie in a puddle of water.
▶ Check the appliance’s supply cord at regular intervals and have it replaced by
Hilti Service if damage is found. Check extension cords at regular intervals and
replace them if found to be damaged.
