1. Safety
1.1 Safety notes and regulations
To ensure safe and reliable work with the high-pressure tester and to protect the user from inju-
ries, the following points are to be observed:
- Read the operating instructions carefully.
- Read and follow the operating instructions for digital pressure gauge DM 80.
- The high-pressure tester may only be operated and installed in systems by
trained motor vehicle specialists who possess the necessary expertise and
qualications to perform these tasks, and who are familiar with the applicable
standards, regulations and requirements of the eld of application.
- The operating instructions are part of the high-pressure tester. Store the
operating instructions in a safe location so that you can quickly nd the desired
information if necessary.
- The legal provisions and regulations as well as those of the vehicle manufacturer
are generally to be observed.
- Prior to commissioning, perform a check to ensure that the high-pressure tester,
along with all its components, is in faultless condition. Do NOT operate the
high-pressure tester if damaged.
- Never kink or pinch pressure lines.
- With daily use, the pressure lines must be replaced after max. 6 years.
- No technical modications may be made to the high-pressure tester or its com-
ponents.
- Do not subject the high-pressure tester or its components to any extreme tem-
peratures, direct sunlight, extreme humidity or moisture.
- Protection class according to DIN 60529: The ambient conditions at the place
of use must not exceed the requirements for the specied protection class (see
Technical data, DM 80 operating instructions).
- Never exceed the maximum measurement range end values of the high-pressure
tester.
- Repairs on the high-pressure tester may only be carried out by the manufacturer.
- Use only original spare parts and accessories.
- Non-specied use of the product or failure to observe the safety and operating
notes may lead to severe malfunctions as well as personal injury and property
damage.
- The discharge of media or hot liquids that are under pressure may cause injuries.
- Pressurised systems may burst and cause parts to be ejected.
- When working on the fuel system, the special safety regulations for ammable
liquids must be observed.
- Wear personal protective equipment, such as protective goggles, gloves, safety
shoes, etc. when working on pressurised systems and components.
