Runleader Small Engine Hour Meter & Tachometer — 2-Pack HM011F, Service Reminder & Battery Backup

The Runleader 2-piece HM011F is a compact digital hour meter and tachometer bundle that tracks engine run time, measures RPM, and alerts you when scheduled service is due.

Designed for lawn tractors, generators, marine engines, and other small engines, this dual-package delivers two independent, easy-to-install instruments that retain settings and log total operating hours. Each module combines an hour counter, programmable maintenance reminder, and a precise tachometer in a weather-resistant housing. With replaceable battery backup and clear numeric readouts, the HM011F helps you schedule maintenance and fine-tune engine idle speeds to extend equipment life.

How does the HM011F show and save total engine running time?

When your engine is off, the display continues to show the accumulated running hours so you can check service intervals without starting equipment. The hour meter logs time with 0.1-hour precision and allows a controlled reset when needed. Internal battery backup maintains stored data during battery changes or power interruptions.

• Visible total hours on the display even when engine is off
• 0.1-hour resolution for accurate tracking
• Retains data during CR2450 battery replacement
• Multiple units in one box to monitor more than one engine

What service reminder features help me stay on schedule?

The HM011F includes a programmable service timer that counts down to your chosen maintenance interval and flashes a warning icon when the preset time arrives. This straightforward reminder removes guesswork, letting you handle tune-ups and oil changes at the correct intervals. You can customize the service interval to match manufacturer recommendations for each engine.

• Settable countdown service timer with alert icon
• Clear visual alert when maintenance is due
• Independent SVC settings per meter for multiple engines

How accurate is the tachometer and how do I use it?

The digital tachometer reports engine speed while running and helps you adjust idle and throttle settings for better performance or fuel economy. It supports different ignition modes, so it can be configured to work with a range of small engines. Readouts are presented clearly to enable quick checks and tuning on the fly.

• Real-time RPM display to fine-tune idle speed
• Programmable for various ignition types
• Helps diagnose running condition and performance

What makes the HM011F easy to install and maintain?

Each meter arrives individually packaged with clear instructions and a straightforward wiring/layout approach suitable for DIY installation. The button control can be disabled to prevent accidental resets, and the user-replaceable CR2450 battery supports long-term data retention. A two-year warranty offers additional protection for peace of mind.

• Simple installation with detailed instructions included
• Operation button can be turned off to protect settings
• Replaceable internal CR2450 battery with data retention
