2. Cut a circular hole with a diameter of 85mm (DN85mm) in the desired mounting location.
3. Insert the tachometer into the hole.
4. Secure the tachometer using the provided mounting bracket and nuts from the rear. Tighten securely to prevent movement.

The tachometer uses a multi-plug socket for convenient wiring. Refer to the wiring diagram typically provided with the product packaging for specific connections. General connections include:

• Ibi ti ina elekitiriki ti nwa: Connect to a 12V or 24V DC power source. Ensure correct polarity.
• Ilẹ: Connect to a reliable ground point.
• Tacho Signal Input: Connect to the engine's tachometer signal output. This is typically from the alternator 'W' terminal, ignition coil, or a dedicated RPM sensor.
• Imọlẹ ẹhin: Connect to a switched 12V/24V source for illumination. The tachometer supports red and yellow dual-color background light, which can be selected during wiring.
• Awọn alatako: For moving magnet gauges operating within an 8V-16V range, extra resistors may be required. Consult the specific wiring diagram for your application.

Ensure all connections are secure and insulated to prevent short circuits and corrosion, especially in marine or harsh environments.

Once properly installed and powered, the KUS Tachometer will display the engine's RPM. The needle indicates the current RPM, scaled by x100 (e.g., '20' on the dial means 2000 RPM). The integrated digital display at the bottom shows the accumulated engine hours.

4.1 Speed Ratio Adjustment

The tachometer has an adjustable speed ratio (0.5-250) to match various engine types and signal sources. This adjustment is typically made via a button or switch on the back of the gauge during initial setup. Refer to the detailed wiring and setup instructions provided with the product for specific steps on how to set the correct speed ratio for your engine.

5. Itọju

The KUS Tachometer is designed for durability and requires minimal maintenance. Follow these guidelines to ensure its longevity:

• Ninu: Clean the gauge face with a soft, damp cloth. Avoid abrasive cleaners or solvents that could damage the glass or bezel.
• Ayewo: Periodically inspect wiring connections for corrosion or looseness. Ensure the mounting remains secure.
• Idaabobo omi: The IP67 rating ensures complete waterproofing. However, avoid directing high-pressure water jets directly at the gauge, especially around the rear connections.

If the tachometer is not functioning correctly, consider the following common issues:

• Ko si Ifihan/Ko si Agbara: Check the power supply and ground connections. Ensure the fuse in the power line is intact.
• Incorrect RPM Reading: Verify the speed ratio setting is correct for your engine. Check the signal wire connection from the engine. Ensure the signal source is functioning properly.
• Awọn kika igba diẹ: Inspect all wiring for loose connections, corrosion, or damage. Ensure the signal source is stable.
• Foging: While the gauge has an anti-fogging function, extreme temperature changes can sometimes cause temporary condensation. This should dissipate quickly. If persistent, check for seal integrity.

If problems persist after checking these points, consult a qualified technician.
