With a faster startup and more power, this handheld trencher will meet all of your digging demands with convenience and performance in mind. The GeoRipper has an 81cc engine and 5.6 horsepower that cuts like butter through even the most demanding applications!

Engineered to reduce flooding, the trencher’s carburetor includes improved deco-valves along with a metering spring to ensure precise fuel regulation every time you start it up. Speaking of startups, the ignition coil with start support function stores electrical power for every single pull, so you don't have to worry about hassle or strain getting your tool to roar to life.

  • Cutting Rock or Pavement- You can remove rocks up to 4" in most soils with your Makita trencher!
  • Utility Work- Trenching allows for wires, piping, and cabling to run underground without objection. Plus, you can easily dig up the ground to reach materials for maintenance.

  • Shoveling Dirt- Your handheld mini trench gives you some relief towards hang digging and shoveling dirt. No more dirty hands, achy body parts, long labor hours, or injuries— the GeoRipper can reach depths of around 3-4 feet to handle any of your smaller scale shoveling jobs.

How to Use Your GeoRipper Mini Trencher GR820

The Makita EK8100 trencher has the precision of a scalpel with its lightweight build and efficient performance! Take a look at some basic operational information below.

Your GeoRipper GR820 Makita trencher takes a standard 50-1 mix in fuel to operate at its best. Zero ethanol, high premium-quality fuel of 90 octane or more works best, as well as a 50-1 mix of a premium, full synthetic fuel. If you're not using fuel in high volumes or for an extensive range of machinery, we recommend looking for something pre-mixed, like a true fuel that is shell-stable and can stay in the engine for a long time.

Whenever you're operating your Makita mini trencher or any other industrial, commercial machinery, always make sure to wear the proper Personal Protective Equipment, better known as PPE.

The best PPE for mini trencher operation includes the following:

  • Eye protection, like safety glasses
  • Ear protection, such as earplugs or 3M ear protectors
  • A full-face shield, made from a polycarbonate material
  • Rugged safety boots or shoes to protect your feet
  • Shin guards to protect against rocky soils and gravel
  • Gloves

Besides your PPE, it's also a convenient and safe practice to keep other tools nearby for quick repairs and maintenance during operation. We recommend tools like a sledgehammer to break up rock jams and an 18 mm wrench to tighten and loosen digging chains.

Simply flip the switch to the ON position, give it about two or three pulls, then listen to your GeoRipper GR820 roar! In the morning or for cold starts, slip the switch to the CHOKE position, give it no more than four pulls, and try to start it up. If it dies, flip the switch to the ON position and proceed with your startup as usual.

Pro Tip: To keep the chain from being on the ground and spinning, especially when in CHOKE, place your foot on the outer loop.
