hello, I recently had an accident with an efg 316 electric forklift.
driving backwards with the load a few meters in front of the ramp, I tried to stop, the reverse foot releasing the levers, which did not react, then pressed the forward levers to check if it blocked, the forklift still did not react. I tried to use the brake lever foot , which also did not react, then i hit the ramp. before i hit ramp when i drive all the diodes were lit on the console and the forklift beeped about an error and displayed error 021. After the impact, nothing worked, there was a need to restart with the key. before the failure everything was working, why was this error? why the forward / reverse levers and the brake stopped working. after restart forklift all work properly.

please help, I'm afraid to drive.
