Runleader HM011F Digital Hour Meter & Tachometer 2-Pack — Small Engine RPM, Programmable Service Reminder

Runleader's 2-piece HM011F is a compact digital hour meter and tachometer combo that tracks engine run time, measures RPM, and provides a programmable maintenance reminder for two small engines.

Designed for lawn mowers, generators, motorcycles, and other small engines, this dual-pack gives you two independent devices to monitor usage and schedule service. Each unit displays total running hours even when the engine is off, logs RPM while the engine runs, and offers a service countdown to alert you when maintenance is due. The set includes two individually packaged hour meters inside a single larger box, making it easy to fit more than one engine into your maintenance plan.

How does the HM011F show total engine running time?

Each Runleader hour meter continually records cumulative run time, and the total is visible on the screen when the engine is off. The display records in 0.1-hour increments and can be reset if you need to start a fresh log for a specific service interval or new engine ownership.

• Visible total-hour readout even when engine is off
• 0.1-hour precision for accurate tracking
• Option to reset total hours when needed

How does the maintenance reminder work and why is it useful?

The programmable service timer counts down from your set interval and triggers a flashing service icon when the scheduled maintenance time arrives. This helps you avoid guesswork and keep tune-ups, oil changes, and inspections timely without relying on memory.

• Set custom service intervals for oil, filters, or inspections
• Flashing icon alerts when maintenance is due
• Countdown display lets you see remaining time until service

Can the HM011F measure engine speed and adapt to different ignition types?

Yes — while the engine runs the unit functions as a tachometer, capturing RPM so you can verify idle speed and performance. The tachometer supports programming for different ignition modes, making it compatible with a wide range of small engines.

• Real-time RPM monitoring to check idle and performance
• Programmable for various ignition systems
• Useful for tuning carburetors or checking engine health

What about installation, power, and durability?

Installation is straightforward with included instructions; the unit runs on an internal CR2450 battery that you can replace without data loss. The operation button can be disabled to prevent accidental changes, and the device retains logged data after battery replacement or power-off. Runleader backs the product with a two-year warranty.

• Simple install with step-by-step guide included
• Replaceable CR2450 battery and retained data after battery change
• Operation button lock to avoid accidental resets
• Two-year limited warranty for added peace of mind

Who is this for: The Runleader 2-pack HM011F is ideal for homeowners, mechanics, rental operators, and hobbyists who manage multiple small engines and want an easy, reliable way to monitor run hours, track RPM, and receive maintenance reminders. If you maintain lawn care equipment, portable power units, bikes, or boats and prefer data-driven service intervals, this compact dual set saves time and helps extend engine life by encouraging timely upkeep.
