In case of an undamaged injector, the operation of its valve will be heard, matching the rhythm of pulses emitted by the tester.
DEVICE MAINTENANCE AND STORAGE
Clean the tester housing with a slightly damp cloth (water) and wipe it dry. Never immerse the tester in water or other liquids.
Keep the tester clamps clean. If there are signs of corrosion or patina, clean the metal parts with a cleaning agent for the copper
electrical terminals.
Store the tester separately so that it is not exposed to impacts, e.g. from other tools in the toolbox. The storage area should be
shaded and well ventilated. It should also protect against unauthorised access, especially by children.
This symbol indicates that waste electrical and electronic equipment (including batteries and storage cells) cannot be disposed of with other types of
waste. Waste equipment should be collected and handed over separately to a collection point for recycling and recovery, in order to reduce the amount
of waste and the use of natural resources. Uncontrolled release of hazardous components contained in electrical and electronic equipment may pose a
risk to human health and have adverse eff ects for the environment. The household plays an important role in contributing to reuse and recovery, including
recycling of waste equipment. For more information about the appropriate recycling methods, contact your local authority or retailer.
