b) Operation
• The product must not get damp or wet, as this could damage it. Therefore, do not use the
product during precipitation, in humid environments or in/under water.
• Use the device in a moderate climate only, do not use it in a tropical climate. For more informa-
tion on acceptable environmental conditions, see the chapter “Technical Data”.
• Never use the product immediately after it has been brought from a cold room into a warm
one. The resulting condensation may lead to malfunctions or damage under certain circum-
stances!
Let the product reach room temperature before using it.
• Protect the product from dust and dirt.
• Please use the product only for measurement, but never for other tasks. •
Do not
use the product as a replacement for a lever or hammer. The product is a high precision
measuring device and must be handled accordingly.
• When you perform sawing on a workpiece for which you have determined an angle or mitre
angle, observe the safety instructions of the saw (and all of the other tools being used) as well
as the general accident prevention regulations.
• Turn the product off when it is not in use.
• If the product is not to be used for a while (e.g., storage), remove the batteries. An ageing
battery may leak and can damage the product! Afterwards, keep the product in a clean, dry,
and out of children’s reach place.
Notes on primary and secondary batteries
• Batteries/rechargeable batteries must be kept out of the reach of children.
• Check that the polarity is correct when inserting/connecting the batteries or rechargeable batteries (pay
attention to plus/+ and minus/-).
• Do not leave batteries/rechargeable batteries lying around; there is a risk that they could be swallowed by
children or pets. If swallowed, consult a doctor immediately, it could be fatal!
• Make sure that batteries/rechargeable batteries are not short-circuited, dismantled or thrown into a fire.
There is a risk of fire and explosion!
• Do not recharge conventional non-rechargeable batteries; risk of explosion!
• Old or flat batteries can leak liquid chemicals that may damage the device. If not used for a longer period
(e.g., in case of storage), remove the inserted batteries/rechargeable batteries.
• Contact of leaking or damaged batteries/rechargeable batteries with the skin can cause acid burns; there-
fore, use suitable protective gloves.
• Liquids leaking from batteries/rechargeable batteries are very chemically aggressive. Objects or surfaces
coming into contact with these liquids may get considerably damaged. Therefore, keep batteries/recharge-
able batteries in a suitable location.
• For the correct disposal of batteries/rechargeable batteries, please read the chapter “Disposal”.
It is possible to operate the product with rechargeable batteries size AAA (Micro). However, the
operating time is reduced by the lower voltage of a rechargeable battery, the self-drain, and the
lower capacity. Therefore, we recommend operating the product only with high-quality alkaline
batteries to ensure long and reliable operation.
