it may cause injuries.

•

Do not operate the appliance in atmospheres con-

taining explosive gases, dust or vapours�

•

When working be aware of the factors which may 

cause wrong measurement results:

•

contamination of laser emitter window;

•

measurement through transparent objects (win-

dows, aquariums, etc�);

•

measurement on reflective surfaces (mirrors, pol

-

ished metal surfaces, etc�);

•

presence of steam, dust, smoke, etc� in the air�

Battery tool use and care

•

Recharge only with the charger specified by the 

manufacturer.

 A charger that is suitable for one type 

of battery pack may create a risk of fire when used with 

another battery pack�

•

Use the appliance only with a suitable battery pack. 

Use of other battery types may cause injuries and fire.

•

Under abusive conditions, liquid may be ejected 

from the battery; avoid contact. If contact acci-

dentally occurs, flush with water. If liquid contacts 

eyes, additionally seek medical help. 

Liquid ejected 

from the battery may cause irritation or burns�

•

Do not open the battery.

 Danger of circuit�

•

In case of damage and improper use of the bat-

tery, vapors may be emitted. Provide for fresh air 

and seek medical help in case of complaints.

 The 

vapors can irritate the respiratory system�

•

When the battery is defective, liquid can escape 

and come into contact with adjacent components

� 

Check any parts concerned� Clean such parts or re-

place them, if required�

•

Protect the battery against heat, e.g., also 

against continuous sun irradiation and fire.

 There 

is danger of explosion�

•

Protect the battery charger from rain and mois-

ture. 

The penetration of water in a battery charger in-

creases the risk of electric shock�

•

Do not charge other batteries.

 The battery charger 

is suitable only for charging lithium ion batteries within 

the listed voltage range� Otherwise there is danger of 

fire and explosion.

•

Keep the battery charger clean.

 Contamination 

may cause the danger of electric shock�

•

Check the battery charger, cable and plug each 

time before using. Do not use the battery charger 

when defects are detected. Do not open the battery 

charger yourself and have it repaired only by quali-

fied personnel using original spare parts.

 Damaged 

battery chargers, cables and plugs increase the risk of 

electric shock�

•

Do not operate the battery charger on easily in-

flammable surfaces (e.g. , paper , textiles , etc.) or 

in combustible environments.

 There is danger of fire 

due to the heating of the battery charger during charging�
