2.1.3 Electromagnetic compatibility
Although the tool complies with the strict requirements of the applicable directives,
Hilti
cannot exclude the
following possibilities:
• The tool may cause interference to other devices (e.g. aircraft navigation equipment).
• The tool may be negatively affected by powerful electromagnetic radiation, possibly leading to incorrect
operation.
In these cases, or if you are otherwise unsure, confirmatory measurements should be made by other means.
2.1.4 Working safely with laser tools
The PLT 300 conforms to Laser Class 2 based on the IEC60825-1 / EN60825-1:2007 standard and complies
with CFR 21 § 1040 (Laser Notice 50).
▶
Do not stare into the beam and do not direct the beam toward other persons. In the event of direct eye
contact with the laser beam, close your eyes and move your head out of the path of the beam.
▶
Laser Class 2/Class II tools may be operated only by appropriately trained persons.
▶
Laser beams should not be projected at eye height.
▶
Precautions must be taken to ensure that the laser beam does not unintentionally strike highly reflective
surfaces.
▶
Precautions must be taken to ensure that persons do not stare directly into the beam.
▶
The laser beam must not be allowed to project beyond the controlled area.
▶
Switch the laser tool off when it is not in use.
▶
When not in use, laser tools should be stored in a place to which unauthorized persons have no access.
▶
Have the PLT 300 and PLC 300 repaired only by Hilti Service.
If the PLT 300 is opened improperly,
laser radiation in excess of Class 2 may be emitted.
2.1.5 Careful use of battery-powered tools
▶
Do not expose batteries to high temperatures, the direct heat of the sun, and keep them away
from fire.
There is a risk of explosion.
▶
Do not disassemble, crush or incinerate batteries and do not subject them to temperatures over
80°C.
This presents a risk of fire, explosion or injury through contact with caustic substances.
▶
Do not subject the battery to hard mechanical impacts and do not throw the battery.
▶
Batteries must be kept out of reach of children.
▶
Avoid ingress of moisture.
Ingress of moisture may cause a short circuit, resulting in burning injuries or
fire.
▶
Under abusive conditions, liquid may be ejected from the battery. Avoid contact with the liquid. If
contact accidentally occurs, flush with water. If the liquid contacts the eyes, also seek medical
attention.
Liquid leaking from the battery may cause irritation or burns.
▶
Use only batteries of the type approved for use with the applicable tool.
Use of other batteries or
use of the batteries for purposes for which they are not intended presents a risk of fire and explosion.
▶
Store the battery in a cool and dry place. Never store the battery where it is exposed to direct sunlight or
sources of heat, e.g. on heaters / radiators or behind glass.
▶
When not in use, keep the battery and the charger away from paper clips, coins, keys, nails,
screws or other small metal objects that could cause a short circuit at the battery terminals or the
charging contacts.
Short-circuiting the contacts on a battery or charger may cause burning injuries or
start a fire.
▶
Do not charge or continue to use damaged batteries (e.g. batteries with cracks, broken parts, bent
or pushed-in and/or pulled-out contacts).
▶
Recharge only with the charger specified by the manufacturer.
A charger that is suitable for a certain
type of battery may present a risk of fire when used with other types of battery.
▶
Observe the special guidelines applicable to the transport, storage and use of Li-ion batteries.
▶
The battery must be insulated or removed from the tool before the tool is shipped or sent by mail.
Leaking batteries may damage the PLT 300.
2.1.6 General safety rules
▶
Before beginning measuring work, check that the accuracy of the tools used is adequate for the
requirements of the task.
▶
Do not operate the PLT 300 in explosive atmospheres, such as in the presence of flammable
liquids, gases or dust.
Tools and appliances create sparks which may ignite the dust or fumes.
