Safety notes
Safety precautions regarding high voltage/mains voltage
Very high tensions occur in electrical facilities. Due to voltage ash-over on damaged components (marten
damage etc.) or touching live components the risk of electric shock is likely.
• Only user power supply lines with earthing contact.
• Only use original cable sets.
• Regularly check cables and power supply unit for damages.
• Always connect the earth lead from device to vehicle rst.
• Carry out installation work, as device connection or component replacement, always when ignition is
turned off.
• Do not touch live components when ignition is turned on.
Safety precautions regarding the danger of suffocation
Carbon monoxide is arising with running engine. When breathed in, it will lead to a lack of oxygen in the blood
(danger to life).
• Ensure the sufcient ventilation of the workplace.
• Always turn on the extraction system and connect it to the vehicle's exhaust when engine is running.
Safety guidelines regarding danger of getting burned
If the engine is running, some components can become very hot (up to several 100°C).
• Always use safety equipment (protective gloves etc.).
• Do not run connection lines near hot components.
Safety guidelines regarding explosion hazard
Fuel vapours increase the risk of re and explosion when working on the fuel system.
• No open re
• Do not smoke
• Ventilate the room well
Safety precautions regarding the danger of injury
The running engine causes some parts to rotate (fan blades, belt drives etc.), which can lead to severe injuries.
If the vehicle is not protected against inadvertent rolling, you may be injured.
• Do not reach into rotating components when engine is running.
• Prevent inadvertent rolling of the vehicle (parking brake).
• Additionally position gear selector of automatic gearboxes to P.
• Do not run cables near rotating parts.
Safety precautions regarding noise
In order to prevent hearing defects, regard the following actions:
• Protect workplaces near the test station against noise.
• Use noise protection products.
Safety precautions regarding chemical burn
Escape of the liquid crystals due to a damaged TFT display can cause chemical burn. Immediately rinse
affected parts of the body or clothing with water (consult a doctor).
• Immediately consult a doctor if the substance has been breathed or swallowed.

Safety notes for mega macs 42
• Connect only an original mains supply (supply voltage 12 V).
• Always take all connections with engine standing still.
• Check the cables of high-voltage components for damage (marten damage etc.).
• Protect the TFT display/device from longer-lasting solar radiation.
• Protect the device and the connection cable from hot components.
• Protect the device from rotating parts.
• Regularly check the connection cables/accessory parts for damage (danger of device destruction due to
short circuit).
• Only connect the device according to user manual.
• Protect the device from water (it is not waterproof).
• Protect the device from strong impacts (do not drop).

Replacing the lithium polymer battery pack
Warning notices for lithium polymer batteries
Storing the batteries
• only in original box
• Storing temperature must not be less 10°C and ust not exceed 50°C
• No exhaustive discharge of batteries allowed. Regularly charge the batteries when stored over a longer
time
Application
1. The batteries are charged ex works with approx. 50%. Before rst operation of the tool, charge the batteries
with the delivered device and regard the operating instructions.
2. Proceed carefully when inserting the batteries.
3. The terminals of the batteries must not be connected - neither incidentally nor intentionally - with one
another and must not get in touch with metal things. The battery pack will have a short circuit and causes a
high short-circuit current.
4. When laying down the battery pack, the batteries and their connections must point to the top. Otherwise,
short circuits are likely.
5. Do not drop the batteries. Do not use damaged or deformed batteries (i.e. after drop).
6. Batteries are no toys and are not suitable for children, they must be kept out of children's reach. This holds for
the charging device, too.
Replacement/repair of the battery pack
• The battery pack is combined with the according electronics and cannot be repaired. The batteries can be
damaged by soldering or mechanical work.
• Only insert the batteries, which are offered by Hella Gutmann Solutions.
• Battery pack and charging electronics are one unit and must always be replaced together.
• From the moment of opening the sales or shipping packaging of the replacement batteries, the user acts
on his own risk and has no claims against the manufacturer, importer and dealer (their assistants as well)
in case of any accidents with personal or material damage.
• The complete battery pack must be immediately replaced in case of a damage on the batery pack or a cell.
Replace it only with a battery pack available at Hella Gutmann Solutions .
WARNING
The non-observance of the above mentioned points can lead to leakage of the batteries, overheating,
explosion or re. Do not use the batteries , if there are any damages, corrosion, smells or excess heat.
An internal short circuit may lead to excess heat only after some hours. If damages on the batteries are
suspected, remove it immediately from the device and position it on a re-proof surface or in a re-proof
container.
Only use the original charging device. If the battery is charged in the wrong direction (too high temperature,
too high voltage, current or wrong charging device), overheating, explosion or re can be the consequence.
