Hi friends !
Asking for your advices - I repaired this truck , every thing is working fine exept just for lifting down function - the speed of lewering down is very low.
According to specification it should be 0.5 m/s.
What was done : removed , inspected and cleaned SPL and SVL valves , also
Pressure Compensator Valve. The electrical signals from Access1 and Access2 were checked on SPL and SVL by oscilloscope - they are OK.
The hydraulic oil also was changed.
Please , any idea what is the problem with so slow lowering ?
Thanks for any replies.
