▶
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.
▶
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, 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.
▶
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 adhering to the surface of the appliance may, under unfavorable conditions, lead to electric
shock.
Dirty or dusty appliances should thus be checked by Hilti Service at regular intervals,
especially if used frequently for working on conductive materials.
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.
Untidiness at the workplace can lead to accidents.
▶
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 picked 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 hotter
than 60°C (140°F), (e.g. glowing cigarette ends, 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.).
▶
Switch the appliance off immediately if foam or liquids escape from it.
▶
Wear protective gloves when using the appliance to pick up hot materials at temperatures of up
to 60°C (140°F).
▶
When working with mineral drilling slurry, wear protective clothing and avoid skin contact with the
slurry (pH > 9: caustic).
▶
Avoid contact with alkaline or acidic liquids. If contact accidentally occurs, rinse 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.
