Scissor lift - strange hydraulic problem.
My unbranded (Chinese) lift that looks like the BendPak MD-6XP has always had a problem of overflowing hydraulic fluid from the filler hole/breather on the oil reservoir when it is lowered.
After reading this thread and looking at youtubes I raised the side with the bleeder so the air runs upwards, opened the bleeder and ran the pump. About three liters of foamy ISO-46 hydraulic fluid came out. Very creamy, aerated , looking. Looked like the top of a good latte.
Umm, I can't figure out why or how the air is getting in, or why it's getting aerated. the lift works well other than the overfowing problem.
Any ideas?
