are cylinders hooked up in parrallel or in series?
valve -> hose -> cylinder -> hose -> cylinder -> valve (very doubtful but figure ask any how)
or.....
valve -> hose -> tee -> cylinder -> tee -> valve
....................... tee -> cylinder -> tee
===============
take bucket off, so you can full extend and contract the cylinders on the FEL. if you are not fully extending / contracting, it can take more times to work out any air in the cylinders. and you may have to operate FEL a dozen times, then shut machine down, wait half day to day, then operate FEL again by fully extending / contracting FEL cylinders. and then repeat.
any air in the cylinders and hoses, will mix with hyd oil. and most likely turn the hyd oil a slightly different color perhaps milky look to the hyd oil. and waiting a day/half day, lets any air in the oil, in the tank. to float up and out. the repeating and usage of FEL. helps remove more air in the cylinders and hoses. and it just takes repeating and usage of FEL to work out the air.
============
at this point working out the air is a big thing and needs to be covered first and should get FEL working like it should once air is worked out, over time / usage, but...double checking couple other things....
with this just being put on, also double check any sort of screen or filter for the hyd oil. most likely there is some sort of screen and/or filter between tank and hose that runs to hyd pumps inlet. the screen may be in the bottom of hyd tank. while filter some place between tank and pump.
if you have quick connects from on FEL to the valve. remove quick disconnects and re-seat them. some times they do not get seated all the way correctly. and barely lets any hyd oil through the connection.
