▶ Close the hose inlet socket with the cap before transporting the appliance and when it is not in use.
2.4 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.
▶ 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.
▶ Do not touch the supply cord or extension cord if they are damaged while working. Pull the plug out of
the power outlet.
▶ 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 to carry the appliance or pull the plug from an outlet. Keep
cord away from heat, oil, sharp edges or moving parts.
▶ When operating an electric appliance outdoors, use only extension cords of a type suitable for outdoor
use. Use of an extension cord suitable for outdoor use reduces the risk of electric shock.
▶ In the event of an interruption in the electric supply, switch the appliance off and unplug it from the power
outlet.
▶ Use the power outlet on the appliance only for the purposes described in the operating instructions.
▶ Never operate the appliance when it is dirty or wet. Dust (especially dust from conductive materials) or
dampness on the surface of the appliance can, under unfavorable conditions, lead to electric shock.
Have dirtied or dusty appliances checked at regular intervals by Hilti Service, especially if they are used
frequently for working on conductive materials.
▶ If use of the appliance in a damp environment cannot be avoided, use a ground fault circuit interrupter.
2.5 Workplace
▶ Ensure that the workplace is well lit.
▶ Ensure that the workplace is well ventilated. Exposure to dust at a poorly ventilated workplace may result
in damage to the health.
▶ Keep the workplace tidy. Objects which could cause injury should be removed from the working area.
▶ Do not operate the appliance in explosive atmospheres, such as in the presence of flammable liquids,
gases or dust. Electric appliances cause sparks which may ignite the dust or fumes.
▶ Use extra care when working on stairs.
2.6 The material vacuumed up
▶ Do not use the appliance to pick up flammable or explosive dusts (magnesium or aluminum dust etc.) or
dusts that present a health hazard. Do not use the appliance to pick up materials with a temperature of
over 60 °C (e.g. glowing cigarettes, hot ash).
▶ Do not use the appliance to pick up flammable, explosive or aggressive liquids (coolants and lubricants,
gasoline, solvents, acids (pH < 5), alkalies (pH > 12.5), etc.).
▶ Do not pick up objects or materials that could cause injury by piercing through the dust bag (e.g. pointed
or sharp objects).
▶ Switch the appliance off immediately if foam or liquids escape from it.
▶ Wear protective gloves when using the vacuum cleaner to pick up hot materials up to a temperature of
60 °C.
▶ When working with mineral drilling slurry, wear protective clothing and avoid skin contact with the slurry
(pH > 9: caustic).
