The device shall be operated exclusively by personnel qualified in vehicle
engineering. Information and knowledge included in this training are not
explained further in this quick start guide.
The manufacturer reserves the right to modify this quick start guide and the
device itself without prior notice. We, therefore, recommend checking for any
updates. This quick start guide must accompany the device in case of sale or
other transfer.
The quick start guide must be kept for the entire service life of the device
and accessible at any time.
1.2 Scope of Functions
The range of functions of the software may vary depending on the country, the
licenses acquired, and/or the optionally available hardware. This
documentation may therefore describe functions that are not available on the
individual device. Missing functions can be enabled by acquiring a
corresponding license subject to charge and/or additional
supporting hardware.
Safety Precautions
2.1 Safety Precautions – Risk of Injury
| When working on the vehicle, there is a risk of injury through rotating parts or rolling of the vehicle. Therefore regard the following:
- Protect the vehicle against rolling away.
- Additionally, place gear selector lever of AT vehicles to park position.
- Deactivate the start/stop system to avoid an inadvertent engine startup.
- Connect the device to the vehicle only when the ignition is switched off.
- Do not reach into rotating components when the engine is running.
- Do not run cables near rotating parts.
- Check the high-voltage parts for damage.
---|---
2.2 Safety Precautions for the mega macs 77
|
To prevent incorrect handling and resulting injuries to the user or destruction of the device, pay attention to the following:
- Ensure that the power plug is accessible.
- Select functions and menus on the touch screen display only with clean fingers. Do not use tools such as a screwdriver.
- Only connect the original power adapter to the power cord (supply voltage 10–15 V).
- Always use the original battery.
- Protect the TFT LCD and the device from long periods of exposure to solar radiation.
- Protect the device and the connecting cable from hot components.
- Protect the device and the connecting cables from rotating parts.
- Regularly check the connecting cables/accessory parts for damage (destruction of the device due to a short circuit).
- Connect the device exclusively according to the user manual.
- Protect the device from fluids such as water, oil, or gasoline. The mega macs 77 is not waterproof.
- Protect the device from strong impacts and do not drop it.
- Do not open the device on your own. Only technicians authorized by Hella Gutmann are allowed to open the device. Warranty and guarantee will be rendered void in any case of unauthorized tampering of the device or if the protective seal is damaged.
- Immediately contact Hella Gutmann or a Hella Gutmann trading partner in case of any malfunctions.
---|---
2.3 Safety Precautions for Testing/Measuring Devices
|
- Perform measurements only on electric circuits that are not directly connected to the line voltage.
- Never exceed the maximum permissible voltage load of 200 V peak alternating voltage (AC) or 200 V direct current voltage (DC) respectively.
- Do not exceed the voltage limits indicated on the connecting cables.
- The voltage values to be measured must be shielded twice or extra from dangerous line voltage. The voltage limits printed on the test leads must not be exceeded. Pay attention that the allowed measuring range of 200 V/DC / 200 V peak is not exceeded when measuring the positive and negative voltage at the same time.
- Never perform measurements on ignition systems (secondary side).
- Regularly check the test and measuring devices for damage.
- Always connect the test and measuring devices to the measurement module (MT 77) first.
- Do not touch the connections/measurement points during the measurement.
