I’ve owned this machine for about three months now. Since I also operate a Yuchai 35-6, I haven’t spent as much time on the DH70 as I could have, but I’ve used it enough to sum up its strengths and weaknesses based on around 500 working hours.

Advantages

  • The exterior looks compact and simple. In my opinion, it’s close to a short-tail design.
  • It has strong digging force.
  • Swing speed is fast (about 11 revolutions per minute).
  • Single movements are quick and responsive.

Shortcomings

  1. Combined (multi-function) operations are slower than you might expect.
  2. The air conditioning doesn’t have an external circulation mode, and the only windows that open are near the door — you can’t lean your head outside.
  3. The interior plastic has a very strong smell, which is quite unpleasant and hard to tolerate.
  4. The cab design is poor — there’s hardly any storage space (just one small spot), and small parts often end up on the cab floor. It’s unclear whether they vibrate loose or were left behind during assembly.
  5. When digging hard soil, the boom and arm make noticeable banging noises (this is definitely not due to insufficient grease).
  6. After about 300 hours, the swing started making strange noises, which disappeared by around 310 hours.
  7. The engine is a Kubota, but it shows signs of burning oil. The oil filler port is poorly positioned and inconvenient to use — a bad design in my opinion. I later added an electric pump myself to make refueling easier.
  8. There’s no designated storage for a grease gun anywhere on the machine. I’ve had to keep mine on the cab floor since day one.

Overall:
The DH70 has decent power and fast basic functions but falls short in cab design, comfort, and user-friendly details. Some issues can be improved with simple DIY modifications, but it would be nice if the manufacturer addressed them in future models.
