Hello to all,

I have Still forklift R20-15, year 2002, sn: 512008017647, buy second hand from an auction / untested and unverified :(

The big problem is code 177, which appears as soon as I start using the forklift.

If I put the ignition on and leave it for a few minutes, I can use the forklift without problems until the evening.

Code 173, appears during the use of the forklift, and manifests itself as it stops working for 2 or 3 seconds, then recovers.

The oil and filter inspection was done recently, and it was found that there was only 5 L in the entire installation.... now I removed all the oil and put 18 L, but the problems persist.

Do you have other ideas, what should I check and test ?
