Setup and Installation

1. Engine Signal Connection

To obtain RPM and hour readings, the signal wire must be wrapped around the engine's spark plug wire. This allows the device to detect the engine's ignition pulses.

2. Product Mounting

The device offers two primary mounting methods:

Stick-on Mounting: Use the provided double-sided tape to adhere the meter to a clean, flat surface.
Screw-on Mounting: Utilize the pre-drilled holes on the device for screw mounting. Screws are not included and must be prepared separately.

Operating Instructions

Hour Meter Function (TOT Hours)

The device continuously tracks the total operating hours of your engine. When the engine is off, the display will show the accumulated total hours. The accuracy is 0.1 hours.

Display showing total hours (TOT HOURS) when engine is off

The display shows "TOT HOURS" when the engine is not running, indicating the total accumulated operating time.

Resetting Total Hours: The total hours can be reset. Refer to the specific instructions in the included user manual for the exact button sequence to perform a reset. This function is useful for tracking hours after an engine overhaul or for specific project durations.

Tachometer Function (RPM)

When the engine is running, the device automatically switches to display the real-time engine RPM. This feature is crucial for tuning your engine, setting idle speeds, and ensuring optimal performance.

Programmable Firing Patterns

For accurate RPM readings, the device can be programmed to match your engine's specific firing pattern. This setting ensures the tachometer correctly interprets the ignition pulses.

This image illustrates how to wrap the signal wire and provides a table of engine firing patterns (1P1R, 1P2R, 2P1R, and 'hour' for hour meter only mode) corresponding to different engine types (e.g., 4 stroke 2 cylinder, 2 stroke 1 cylinder).

Consult the detailed instructions in your user manual for how to access and change these settings to match your engine type (e.g., 2-stroke, 4-stroke, number of cylinders).

User Shutdown

The device features a user shutdown function, allowing you to turn it off when not in use. All recorded data, including total hours, will be saved and retained even after shutdown.

Maintenance

Maintenance Reminder (SVC)

The device includes a programmable service timer. You can set a desired maintenance interval. Once the set time is reached, a maintenance warning icon will flash on the display, reminding you that service is due.

Setting the SVC Reminder: Refer to the user manual for detailed instructions on how to program the service interval.
Disabling the SVC Reminder: The SVC reminder can be temporarily or permanently disabled if desired.

Troubleshooting

If you encounter issues with your Runleader Digital Hour Meter Tachometer, please review the following common problems and solutions:

Problem	Possible Cause / Solution
No display / Device not turning on	Ensure the device is not in user shutdown mode. Press the 'M' or 'S' button to wake it up. The internal battery may be depleted. While not replaceable, the battery is designed for long life. If the device is new and not working, contact support.
Inaccurate RPM readings	Check the signal wire connection to the spark plug wire. Ensure it is wrapped securely for 5 turns. Verify that the programmable firing pattern setting matches your engine type (e.g., 2-stroke, 4-stroke, number of cylinders). Adjust as per the manual. Ensure the spark plug wire is not damaged or excessively shielded, which could interfere with signal detection.
Hour meter not accumulating hours	Confirm the engine is running and the signal wire is correctly connected. Check if the device is set to "RPM shutdown" mode, which means it functions as an hour meter only when the engine is off.
Maintenance reminder not working	Ensure the SVC interval has been correctly programmed and is not set to "OFF". Verify that enough operating hours have accumulated to trigger the reminder.

If these steps do not resolve the issue, please contact Runleader customer support for further assistance.
