3. Setup and Installation
Follow these steps to properly install your Runleader RL-HMB005 mounting bracket and compatible meter.
3.1 Important Caution
CAUTION: DO NOT HIT THE PLASTIC PIPE MOUNTING BRACKET TO AVOID FRACTURE. Apply gentle, even pressure during installation.
3.2 Installation Steps
- Prepare the Meter: Install your hour meter or tach/hour meter according to the specific directions provided with the meter's packaging.
- Attach Meter to Bracket: Use the screws included with your hour meter or tach/hour meter to securely fasten the meter to the RL-HMB005 pipe mounting bracket. Ensure a snug fit without overtightening.
- Mount Bracket to Pipe: Use the two cable ties (included with the meter or bracket) through the designated holes on the bracket. Wrap the cable ties around the device's pipe (diameter 18mm-30mm) and secure them tightly to fasten the meter and bracket assembly to the pipe.

4. Operating Instructions
The Runleader RL-HMB005 is a passive mounting bracket. Once installed, its function is to securely hold your compatible Runleader hour meter, tachometer, or vibration meter in place. The operation of the mounted device is independent of the bracket and should be referred to in the specific instruction manual for that device.
5. Maintenance
The RL-HMB005 mounting bracket requires minimal maintenance.
- Cleaning: Wipe the bracket with a soft, damp cloth to remove dust or dirt. Avoid using harsh chemicals or abrasive cleaners, as these may damage the nylon material.
- Inspection: Periodically check the bracket and its fasteners (screws, cable ties) to ensure they remain secure. Tighten if necessary.
- Storage: If removing the bracket for storage, keep it in a clean, dry place away from direct sunlight and extreme temperatures.
6. Troubleshooting
As a passive component, the RL-HMB005 bracket has limited troubleshooting scenarios.
- Bracket is Loose: Ensure that the screws fastening the meter to the bracket are tight, and the cable ties securing the bracket to the pipe are pulled taut.
- Bracket Appears Damaged: If the bracket shows signs of cracking or breakage, especially after impact, it should be replaced immediately to prevent the mounted device from falling.
- Meter Not Functioning: If the mounted meter is not working, refer to the troubleshooting section of the meter's specific instruction manual. The bracket itself does not affect the meter's electronic operation.
