▶
Do not use the product with a damaged supply cord or supply cord plug. If the supply cord or supply cord plug is damaged, bring the
product to a certified Hilti service center for checking and/or repair.
▶
Do not route the supply cord underneath carpets, furniture or other items. Do not cover the supply cord with small mats, runners or similar
covers. Route the supply cord outside known pathways and make sure that the supply cord does not cause a trip hazard.
▶
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.
▶
Check to ensure that the supply cord does not lie in a puddle of water.
▶
Check the product'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.
▶
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 or extension cords present a risk of electric shock.
▶
The electric supply cord may be replaced only with a cord of the type specified in the operating instructions.
▶
Do not abuse the cord. Never use the cord for carrying, hanging up or unplugging the product. Keep the cord away from heat, oil, sharp
edges and moving parts of the product. Damaged or entangled cords increase the risk of electric shock.
▶
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.
▶
In the event of an interruption in the electric supply, switch the product off and unplug it from the power outlet.
▶
When fitting the suction head on to the vacuum cleaner, take care to avoid pinching your fingers or damaging the supply cord. This presents
a risk of injury or damage.
▶
Do not expose the product to rain or moisture. Water entering an electric device will increase the risk of electric shock.
▶
Never operate the product when it is dirty or wet. Dust (especially dust from conductive materials) or dampness on the surface of the product
may, under unfavorable conditions, lead to electric shock. Have dirtied or dusty products checked at regular intervals by Hilti Service,
especially if they are used frequently for working on conductive materials.
▶
Before carrying out care and maintenance work, changing filters or accessories or leaving the product temporarily out of use (e.g. for work
breaks), disconnect the product from the primary power supply (disconnect the supply cord plug from the power outlet, remove the battery).
This safety precaution prevents the product from starting accidentally.
▶
Use an antistatic suction hose in order to avoid electrostatic effects.
Careful handling and use of the product
▶
Never leave the product unattended.
▶
Operate the vacuum cleaner only with the main filter installed and intact. Always check the filter prior to each use of the vacuum cleaner.
▶
Protect the product from frost.
▶
Check the product 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. All parts must be fitted correctly and fulfill all conditions necessary for correct operation of the product.
▶
Have your product repaired only by qualified, skilled personnel, using only genuine Hilti spare parts. This ensures that the safety of the
product is maintained.
▶
Do not transport the product by crane or with other hoists.
▶
Do not stand on the product (do not use it as a substitute for a ladder).
▶
Clean the water level limiting device regularly with a brush, in accordance with the instructions, and check it for signs of damage.
Additional instructions for vacuuming up potentially explosive substances
▶
Have the ground connection continuity-tested at regular intervals. Orient yourself by the local laws and regulations of the place of use.
▶
Route the suction hose carefully while operation is in progress and avoid kinks.
▶
Check the suction hose and waste material container at regular intervals for dust build-ups and remove dust build-ups, if found, from the
suction hose, the waste material container and the housing of the product. Build-ups of dust or traces of liquids can constitute a potential
source of ignition.
▶
Connect the product only to dust-producing products that produce no sources of ignition (e.g. hot metal chips, sparks).
▶
Make sure that conductive machine parts of system products are electrostatically grounded. These also include extractor hoods and
conductive parts of products and tools of class II. Electrostatic grounding can be established via the product itself or via a separate
electrostatic grounding facility.
▶
Use only accessories recommended by Hilti. The use of other accessories can lead to a risk of explosion.
▶
Always activate the filter cleaning system when vacuuming up hazardous dusts, especially when the appliance is used in combination with
power tools that generate dust.
