Package Contents

The image displays the Runleader hour meter along with its accessories: a user manual, double-sided adhesive tape, two screws, and the product's color packaging box.
- 1 x Runleader Wireless Digital Hour Meter (RL-HM016B)
- 1 x User Manual
- 1 x Double-sided Adhesive Tape
- 2 x Mounting Screws
Installation
The hour meter can be installed using either adhesive tape or screws, depending on the mounting surface and desired permanence. Choose a location on your equipment that experiences consistent vibration during operation.
Mounting Options

This diagram illustrates two methods for mounting the hour meter: using double-sided adhesive for a quick attachment or using screws for a more secure, permanent installation.
- Adhesive Mounting: Clean the mounting surface thoroughly. Peel off the protective film from the double-sided adhesive tape and firmly press the hour meter onto the desired location. Ensure the surface is flat and clean for optimal adhesion.
- Screw Mounting: Use the provided screws to secure the hour meter to the equipment. Pre-drill pilot holes if necessary to prevent damage to the mounting surface.
Vibration Sensitivity Adjustment
The meter's vibration sensitivity can be adjusted to match your equipment's vibration intensity. This ensures accurate hour tracking.

The image displays the three vibration sensitivity modes: SEN-1 (Low Sensitivity), SEN-2 (Medium Sensitivity), and SEN-3 (High Sensitivity). Adjust this setting based on the vibration intensity of your machine.
- SEN-1 (Low Sensitivity): For equipment with strong vibrations (e.g., some generators, high-frequency vibrations >32Hz).
- SEN-2 (Medium Sensitivity): For equipment with moderate vibrations (e.g., lawn mowers, vibrations >18Hz).
- SEN-3 (High Sensitivity): For equipment with low vibrations (e.g., electric fans, vibrations >4Hz).
Refer to the detailed instructions in the user manual for how to enter the sensitivity adjustment mode and select the appropriate level.
Operating Instructions
Total Hour Meter (TOT)

The image shows the hour meter displaying '8:36' under 'HEURES TOT', indicating the total accumulated operating hours. This value is not resettable.
The TOT display shows the total operating hours of your equipment. This value accumulates automatically when the device detects vibration and cannot be reset by the user. It provides a permanent record of the machine's lifespan.
Resettable Job Timers (JOB1 & JOB2)

This image demonstrates the JOB1 and JOB2 timers. It shows a timer displaying '0:15' and then being reset to '0000:00', indicating these timers are resettable for tracking specific tasks.
Use JOB1 and JOB2 to track the duration of specific tasks. For example, you can reset a JOB timer before an oil change to record how long the engine runs until the next service. To reset a JOB timer, press and hold the appropriate button until the display shows '0000:00'.
Maintenance Reminders (SVC1 & SVC2)

The image shows SVC1 and SVC2 timers set to '55:00' and then counting down, indicating their function as maintenance reminders. These timers track usage until a preset service interval is reached.
The SVC1 and SVC2 timers are programmable countdown timers for maintenance. Set a desired service interval (e.g., 50 hours). The timer will count down as the engine operates. Once it reaches zero, a reminder icon will appear, indicating that maintenance is due. To reset a SVC timer after maintenance, refer to the detailed instructions in the user manual.
Lock Function

This image illustrates the lock function. It shows the hour meter displaying '8:36', then transitioning to 'LOC' (Locked), and finally the screen turning off, indicating that the device is in a power-saving, non-recording state.
To prevent accidental hour accumulation during transport or when the equipment is not in use, activate the lock function. When locked, the display will show 'LOC' briefly and then turn off, conserving battery life and pausing all timing functions. To unlock, press the button again.
Maintenance
The Runleader RL-HM016B is designed for low maintenance. The internal battery is sealed and not user-replaceable. When the battery life ends, the unit will cease to function.
- Cleaning: Wipe the unit with a soft, damp cloth. Do not use harsh chemicals or abrasive cleaners.
- Water Resistance: The unit is IP68 waterproof. However, avoid prolonged submersion or high-pressure water jets to ensure longevity.
- Battery Life: The sealed internal battery is designed for long-term use. There is no user-serviceable battery compartment.
Troubleshooting
- Meter not accumulating hours: Ensure the vibration sensitivity is set correctly for your equipment. If the vibration is too low, increase the sensitivity (e.g., to SEN-3). Check that the meter is securely mounted to a part of the equipment that vibrates during operation. Ensure the lock function is not activated.
- Display is blank: The meter might be in lock mode. Press the button to reactivate the display. If the display remains blank, the internal battery may be depleted, indicating the end of the product's lifespan.
- Inaccurate readings: Adjust the vibration sensitivity. If the meter is accumulating hours when the machine is off, decrease the sensitivity. If it's not accumulating hours when the machine is on, increase the sensitivity. Ensure the mounting location provides a clear vibration signal.
