Hi there,
My machine has been temporarily losing the ability to lift the boom off the ground and travel.
All the functions seem very weak when this is happening, so it maybe all functions are having almost no power and the boom lift and travel are not really or barely moving due to having a bit of resistance.
This was occurring on the occasion, maybe 1 or 2 times a day but with this hot weather the past few days here in Australia it has been happening often, and affecting work.
Thursday was the worst, being 42 degrees C out side, it was happening at least every 15 mins and it was incredibly annoying. It usually only happens for a few seconds but Thursday afternoon i was working it real hard and the boom went week and could not get it off the ground at all after trying for a few minutes! so had to pack up for the day.
I thought it could be air in the lines because i did have this happen a few months back after i changed all the hydraulic oil, filter and strainer, but I do cycle the cylinders to bleed any air in the system and it still occurs no matter how often i do the hole air bleeding procedure.
Occasionally when the machine hasn't been used in a few days when starting it up the hydraulic pump sounds like it has air in it for a about 2 seconds then sounds normal.
If anyone could help with this i would really appreciate it.
