Concrete grinder, saw, and scarifier operators who track engine hours for maintenance scheduling, warranty compliance, or resale value depend on a working hour meter — and when the factory unit on a gas-engine EDCO machine fails or goes missing, the EDCO 15138 Inductive Hour Meter is the direct OEM replacement. Built for surface prep contractors and rental fleet managers running EDCO grinders, saws, and scarifiers, it reads engine run time without any direct electrical connection, so the swap is a five-minute job rather than a shop visit.
Use Cases
- Maintenance interval tracking — Log run time against the manufacturer's service schedule for oil changes, air filter swaps, and blade or tooling wear checks, instead of guessing from calendar days.
- Resale and trade-in value documentation — A working hour meter gives buyers verifiable proof of usage, which supports a stronger resale or trade-in price on used surface prep equipment.
- Rental fleet hour tracking — Rental houses and fleet managers use hour readings to schedule preventive maintenance across a fleet and to bill hourly usage accurately.
- Retrofit onto any small gas engine — Because it senses ignition pulses inductively, it can be added to grinders, saws, or other gas-powered equipment that never shipped with a meter.
- Warranty and service verification — Documented hours support warranty claims and give a service technician an accurate starting point for diagnosing wear-related issues.

Frequently asked questions
What EDCO equipment does the 15138 hour meter fit?
It is listed as an accessory/replacement part for EDCO's gas-engine classic floor grinders and is used across other EDCO gas-powered surface prep machines, including saws and scarifiers. Check your machine's EDCO parts list or call our team with your model number to confirm fitment before ordering.
How does an inductive hour meter install, and does it require wiring into the engine?
No. The meter's pickup wire simply wraps around the spark plug wire (or coil wire on magneto-fired engines) close to the plug boot. It reads the ignition pulse inductively, so there is no cutting, splicing, or direct electrical connection to make.
Does the EDCO 15138 need a battery, and can it be replaced?
The meter is self-powered by an internal sealed battery rated for years of service under normal use. Like most inductive hour meters in this class, the battery is not user-replaceable; when it reaches end of life, the unit is replaced as a whole.
Can I use this hour meter to schedule maintenance on my grinder or saw?
Yes. Recording accumulated engine hours lets you follow EDCO's recommended service intervals for oil changes, filter replacement, and wear-part inspection rather than relying on calendar time, which is especially useful for equipment that sits idle between jobs.
Will an inductive hour meter work on both 2-stroke and 4-stroke gas engines?
Yes. Inductive sensing reads the ignition pulse from the spark plug or coil wire, so it works on both 2-stroke and 4-stroke single- and twin-cylinder gasoline engines commonly used on surface prep equipment.
