The point from which the measurement is taken
is clearly identified by the red spot. The range of
the tool depends on the reflectance and surface
finish at the point where the measurement is
taken. The reference point on the tool can be

2. Safety information
WARNING
Misuse may lead to injury, malfunction
and damage to property. The owner
must inform the user of the operating
risks associated with the equipment
and the corresponding safety
precautions. The P 20 laser range
meter may be operated only when the
user has received prior instruction.
Operating limits
See “Technical data” section.
Environ ent
The product is suitable for use in atmospheres
permanently habitable by humans. It must not
be used in corrosive or explosive environments.
Exposure to rain for short periods during use is
permissible.
Division of responsibilities
Responsibility of the anufacturer of
the original equip ent, Hilti Corporation,
FL 9494 Schaan (subsequently referred to
as “Hilti”)
Hilti is responsible for supplying a technically
safe product in faultless condition, including
operating instructions and original accessories.
The responsibility of other anufacturers
supplying accessories
The manufacturers of accessories (not supplied
by Hilti) for the Hilti P 20 are responsible for
the development, implementation and
communication of safety strategies for their

such risks in advance where possible.
The owner of the tool must ensure that these
instructions are understood and followed by all
users.
Purpose
Intended uses
The Hilti P 20 is intended for the following
range of applications:
• Measuring distances
• Calculating areas, volumes and remote
heights (side of right-angled triangle)
• Addition and subtraction of distances
Examples of misuse
• Use of the product without prior instruction
• Use of the product outside its operating limits
• Rendering safety devices ineffective or
removing notices and warning signs
• Opening the product unless expressly
permitted in certain cases (e.g. to replace the
batteries)

2. Safety information
CAUTION
Take care to avoid incorrect
measurements caused by using a
defective product or a product which
has been dropped or subjected to any
other inadmissible stresses or
changes.
Preventative easures
Carry out measurements periodically to check
the accuracy of the product, particularly after it
has been exposed to excessive stresses and
before and after important measuring tasks.
WARNING
Failure to adequately cordon off the
area in which you are measuring may
lead to dangerous situations in road
traffic, on building sites or in industrial
plants, etc.
Preventative easures
Always ensure that the area in which you are
carrying out measuring work is properly
cordoned off. Observe the statutory accident
prevention regulations and road traffic
regulations of the applicable country.
CAUTION
Taking measurements from surfaces
with low reflectance surrounded by
areas with high reflectance may lead
to measurement errors.
Preventative easures
Take measurements from the brown side of the
Hilti target plate at distances above 40 m.
CAUTION
Rapidly changing conditions such as
large changes in distance while in
tracking mode or rapidly moving
target objects may lead to
measurement errors.
Operating risks, continued

2. Safety information
Responsibility of the owner
WARNING
The owner is responsible for the
correct use of the equipment, the use
of the equipment by his employees,
their instruction and the operating
safety of the equipment.

information on the product and the
information contained in the operating
instructions.
• To be aware of the locally applicable
industrial accident prevention regulations.
• To notify Hilti immediately of any safety-
related defects or deficiencies in the
equipment.
Operating ris s
WARNING

or with incomplete instruction may
lead to errors by the operator or
misuse and thus to accidents resulting
in serious personal injury, pecuniary
damage or damage to property and
the environment.
Preventative easures
All users must observe the safety information
issued by the manufacturer and the owner’s
instructions.
CAUTION
Care must be taken to avoid incorrect
measurements.
Preventative easures

2. Safety information
CAUTION
If the equipment is not used for
lengthy periods, there is a risk of it
being damaged by leaking batteries.
Preventative easures
Remove the batteries if you do not intend to use
the equipment for some time.
CAUTION
At regular intervals or before
measuring, check that the folding
spike functions correctly.
The symbol illustrated is shown in the
display.
Operating risks, continued
continued
2. Safety information
Preventative easures
– Take individual measurements
– Set up the tool in a fixed position (tripod)
CAUTION
Objects moving through the path of
the laser beam while measuring may
lead to incorrect measurements.
Preventative easures
Take care to ensure that no objects move
through the path of the laser beam.
CAUTION
Inadmissible mechanical influences
during the shipping or disposal of
charged batteries may lead to a risk of
fire.
Preventative easures
Remove the batteries from the tool before
shipping and dispose of them only when fully
discharged (operate the tool in tracking mode
until the batteries are discharged).
CAUTION
Opening the product without
authorisation will not only invalidate
the warranty, it may also cause
malfunctions and measuring errors.
Preventative easures
o not open the product! Only the battery
compartment cover should be opened when
replacing the batteries.
