Warning!
Text with this symbol contains information for your safety and how you can reduce
the risk of severe or fatal injury.
The WARNING symbol warrants particular attention for your safety.
Caution!
Text with this symbol contains information about how you can avoid damage to the
vehicle and the tester.
The Caution symbol tells you that if the information is ignored, damage to the
vehicle and/or the tester could result (e.g.: Ensure that the touch screen is not
touched with sharp, edged objects.).
Note
Text with this symbol contains additional, useful information.
A Note symbol contains other, special instructions for using the device, and
related information.
Note on further safety instructions
The general safety instructions, which are valid for the VAS 6356, are listed in the
following. Further safety instructions are to be found in the operating manuals.
Therefore, please read the operating manuals before use. Safety instructions may
also appear on the screen of the tester. Follow all the instructions displayed.

IMPORTANT SAFETY INSTRUCTIONS
VAS 6356 Operating Manual Hardware V1.07 05/18All rights reserved.
ii
IMPORTANT SAFETY INSTRUCTIONS
1. Warning!
Risk of explosions
The VAS 6356 has internal parts which emit sparks and therefore must not be
exposed to flammable fumes. The VAS 6356 should be operated at least 460 mm (18
inches) above the floor surface since fumes from fuels and other materials
accumulate at floor level.
2. Warning!
All measurement cables may only be used within the measurement ranges stipulated
in the technical specifications and the descriptions in the operating manual. All
measurement pick-ups may only be used on cable whose casing is undamaged. Do
not carry out measurements on damaged cables.
3. Warning!
The devices connected to electrical power supply correspond to protection class 1
and are fitted with a safety-tested mains cable. They may only be connected to
electrical networks with an earthed protective conductor (TN networks) or electrical
outlets with earthed protective conductors.
4. Caution!
Fluctuations and deviations in the power supply beyond the permitted range of
tolerance can lead to malfunctions and damage.
5. Warning!
Electrical ignition systems carry voltages of up to approx. 30 kV. Observe general
safety guidelines for workshops at all times.

iii
6. Warning!
If you open the VAS 6356 or its accessories without authorisation or carry out
improper alterations to them, considerable risk to you and to the device may result.
7. Caution! VAS 6556 workshop trolley - ventilation
When operating the VAS 6556 workshop trolley, ensure sufficient ventilation of the
table power adapters of the printer and of the test instrument box VAS 6356.
Remember that the printer remains switched on even when the tester is switched off
and even if it has entered the energy-saving mode.
Open the roll-up door fully during operation.
The heat dissipation of the table power adapter must not be blocked by articles
placed on top (cables, rags, etc.).
Pull the power cable from the workshop trolley to switch off the complete device.
8. Caution! When connecting non-VW vehicles
The VAS 6356 has been developed for vehicles from the Volkswagen group.
Connecting the VAS 6356 directly to vehicles from other manufacturers can therefore
result in damage to the vehicle.
9. Caution! When cleaning the VAS 6356
Pull out the DC supply plug before cleaning the VAS 6356.
Clean the VAS 6356 only with a dry cloth.
Do not use cleaners or solvents.
10. Caution! When using magnetically sensitive
objects
Do not bring any magnetically sensitive objects in the vicinity of the magnetic clamps
at the upper or lower side of the VAS 6356.

IMPORTANT SAFETY INSTRUCTIONS
1. Read all instructions.
2. Care must be taken as burns can occur from touching hot parts.
3. Do not operate equipment with a damaged cord or if the equipment has
been dropped or damaged –until it has been examined by a qualified
service person.
4. Do not let a cord hang over the edge of the table, bench, or counter or
come in contact with hot manifolds or moving fan blades.
5. If an extension cord is necessary, a cord with a current rating equal to or
more than that of the equipment should be used. Cords rated for less
current than the equipment may overheat. Care should be taken to
arrange the cord so that it will not be tripped over or pulled.
6. Always unplug equipment from electrical outlet when not in use. Never
use the cord to pull the plug from the outlet. Grasp plug and pull to
disconnect.
7. Let equipment cool completely before putting away. Loop cord loosely
around equipment when storing.
8. To reduce the risk of fire, do not operate equipment in the vicinity of open
containers of flammable liquids (gasoline).
9. Adequate ventilation should be provided when working on operating
internal combustion engines.
10. Keep hair, loose clothing, fingers, and all parts of body away from moving
parts.
11. To reduce the risk of electrical shock, do not use on wet surfaces or
expose to rain.
12. Use only as described in this manual. Use only manufacturer’s
recommended attachments.
13. ALWAYS WEAR SAFETY GLASSES. Everyday eyeglasses only have
impact resistant lenses, they are not safety glasses.
