Runleader RL-HM011F Digital Hour Meter, Small Engine Tachometer

I had for about 8 years the high dollar version of this product. After 8 hours the battery failed and there was no way to replace the battery. So, I decided to purchase this unit, the Runleader RL-HM011F. It has a way to replace the battery when the time comes. It is easy to setup and easy to read. The display is great! It doesn't fit the opening that my panel had for the high dollar model, but, this one uses the same bolt holes so all I had to do was surface mount it. It might not be as good are the other unit's mount, but it is good enough and gives me the information I need. This was easy to install, took of about 10 minutes. All in all this unit is a great value and works great for my needs. Well worth a full 5 stars!

Just bought another one for a DR Field and Brush mower with the 17hp Kawasaki 2cyl. Haven’t installed it yet but will as soon as it quits freaking raining. I really believe in these. I’ve had one of these on a Honda Eu2000 for years and like it so I bought another for my bigger Wen 4050 generator. It has good features and the battery is still going in the original one I bought. Occasionally the old one fails to turn off automatically but pressing both buttons at once turns it off.

This is a great little device for keeping track of hours on small engines. I purchased this to install on my new 1000 watt generator so I know how many hours it has on it between oil changes. This works great for tracking hours and has a nice feature that you can set for reminders but I tried all different settings and different twists on the spark plug wire but could not get the RPMs to register correctly ( this is why am knocking it down to four stars )so if you’re buying it to monitor RPMs I would be cautious as it may not work for you however if you’re looking for just tracking hours and reminders between oil changes this is an excellent device for that and I would highly recommend. One nice feature is as soon as you start the engine it does come on automatically but you do have to turn it off manually because it does not shut off automatically and could possibly drain the battery quicker. One other thing I did not like is that the battery is super hard to keep in place while trying to re-insert the battery cover ( it kept wanting to pop out! ) and it did not seem to have a good seal on the battery cover door so I would keep it from getting wet. Also one more note is that when or if you are using it for engine RPMs you cannot see your engine hours until you shut the engine off. If you are using it just to display engine hours it will show you the hours even when the engine is running.

This meter is compact enough to mount almost anywhere, and the instructions are clear enough that setup doesn’t feel overwhelming. Installation is mostly straightforward, but wrapping the pickup wire around the spark‑plug lead takes some patience — it works well once it’s on, but getting a tight, even wrap is the slowest part of the job. Once installed, the tach reads accurately, the hour counter tracks reliably, and the maintenance reminders are genuinely useful. The replaceable battery is a big plus compared to sealed units, and the display is easy to read in the garage. For the price, it’s a dependable little tool that makes tuning and upkeep a lot easier.

I installed on a Pulsar GD400BN generator, I used the 1P1R firing pattern and wound the wire five loops around the spark plug cable. I set the service timer reminder at 50 hours and confirmed with my watch that the running time was working properly it showed .4 hours and my watch said 25 minutes I consider that very accurate. The RPMs were as follows: 3,260 on low idle, 3,370 high speed no load, with a 2,230 watt load the RPMs were 4,270. The generator user manual states 4600 RPMs is the maximum for this engine at full load which is 3,000 running Watts, I am comfortable with the readings I'm getting they may not be exact but they are very close to exact, later on I will purchase a Briggs & Stratton manual tachometer and I will verify if these numbers are right on the money. The directions are correct although at times a bit vague and the font is tiny and it was very difficult for me to be able to read it. I am very pleased with the device, the fact that it came with a battery that is replaceable and the fact that I can turn off the display when I'm not using it, I recommend it.

I use these on my Cub Cadet tractors and track inspection cars. The hour meter on the tractors I've purchased no longer work and they're perfect, especially for the maintenance interval. Thanks Runleader!

Instructions are confusing and not very clear. The unit does not appear to be very accurate and it didn't make a difference how many wraps I had. My atv idle speed should be around 1250 to 1350. I had to idle it at around 2300 for it to not stall out. Now, I worked on many vehicles over the years (I'm 71) and driven a lot with tachs in them. When the tach read 3000 rpm, there is no way it was idling at 3000 rpm. I also revved it up a little and the tach went around 9000 rpm! NO WAY! And yes I had the tach set up properly for 1p2r for a 4 stroke engine. It's not worth sending back.

I put a replacement engine (B&S 625EX, 150cc, 4-stroke) on my 21" Snapper deck, and wanted to ensure the engine's RPMs were correct for a 21" blade. Once I set the correct engine type on the tachometer (4-stroke, one cylinder "1P2R"), the instructions said to wrap the cable around the spark plug wire 4 to 5 times. I did so, and the RPMs read 7650, which is over TWICE the maximum-rated RPMs for a small engine. Surprised at it being WAY too high (even though it didn't sound anywhere NEAR that high), I reduced the RPMs down to as low as they would go by bending the arm to which the governor spring is attached. The tach still read 4180 RPM and the engine was barely idling. I checked the instructions to make sure I configured and attached it right. I definitely configured it right, and I hooked it up according to the instructions, but reading down a bit further the instructions THEN say (paraphrased) "If the is reading too high, reduce the number of wraps ("winding turns"), or if it is too low, increase the number or wraps." If we're following the instructions, then why should we have to increase or decrease the number of wraps? Don't they KNOW the correct number of wraps their own tool requires? And then, even further down, it says, for a 4-stroke engine, to wrap the wire around the coil head, not the plug wire. Talk about some BAD technical writing. Shouldn't THAT information come first? You would have to take the housing off of the engine to wrap the lead around the coil head (assuming you could actually get it around the coil head without removing the coil and reinstalling it), which would then require you either to start the engine with a drill using the fly wheel nut, or to reinstall the housing so you can use the pull cord. Nope. If they're not sure how many wraps around the spark plug there needs to be, then your adjusting the tool (the tachometer) to accommodate a potentially inaccurate reading, which MISSES the whole point of using the tachometer in the first place. If we're just going to make up numbers, then what do we need a tachometer for? And double nope. If they can't make up their minds about where they're going to instruct the user to attach the sensor cable, then what good are the instructions? What good is the meter? Maybe the instructions for all tachometers are this bad, but THIS manufacturer has already lost ALL of my confidence. I need a tool that I can trust, not something where the manufacturer doesn't even know the correct order to present the instructions, doesn't know how to attach its tool correctly, just makes things up as it goes along, and ultimately gives the user ZERO confidence in the tool's reading. RETURN!

Gummidichtung für Batteriefach war bei Ankunft bereits verklemmt und ergo beschädigt. Damit ist das Fach nicht mehr wasserdicht. Kann passieren, für mich war das keine Voraussetzung beim Kauf also egal und ist ausgenommen von der Gesamtbewertung. Inbetriebnahme und Einstellungen sind rudimentär aber ausreichend und zweckdienlich. In der Preisklasse darf ich nur beurteilen, ob das Gerät den Angaben entsprechend funktioniert, alles darüber wäre vermessen zu erwarten. Ich habe keine Möglichkeit die Genauigkeit des Gerätes zu prüfen aber das Gerät ist funktionstüchtig und angezeigte Daten scheinen glaubwürdig. Schnelle Lieferung und gratis Versand nach Österreich ... 5 Sterne und ein Dankescön

Broken in 5 days Change the battery also not working

Wired in unit, set up for engine, started engine, all good. Returned 1hour later, started engine, the digits cycle randomly, doesn’t work & continues not to work. Ordered another from elsewhere.

Fa quello che promette e sembra(miracolosamente)farlo bene. I giri stimati sembran plausibili.non ho notato differenze in tal.senso aumemtanso o diminuendo il numero di spire. Il funzionamento é semplice, sul sito del produttore trovare le istruzioni in pdf..l autonomia(sulla carta)é altissima, solo la guarnizione del vano che la contiene mi lascia perplesso sulla effettiva impermeabilità. A didferrnza di altri si azzera, potete scegliere il promemoria della manutenzionene se vedere sempre il conta ore al posto del conta giri o vedere le ore solo a macchina spenta..ad ora nn ho davvero nulla da volere in più!

Instalação super fácil e funciona tal como descrito, permitindo medir com precisão as rotações do motor da minha mota Yamaha FZX750.
