4200xl Hydraulics slow?

[osikasculptor]

I would make sure all electrical connections are plugged in. 4th valve servo is channel 8 on my receiver. When radio and machine is turned on and the pump is off see if that dial moves the servo on the block (or rather listen if you hear it move) On mine the pressure valve is screwed all the way in and this dial then adjusts the pressure with the mix toggle on the right in the down position.

Beyond that it could be the servo or a bunch of other things to track down and trouble shoot? Martin "DiggingwithMartin" on you tube does a lot of repair work for guys who own these and is super nice!

Also lots of guys on this forum who have super in depth knowledge about radios and everything else.. and who are also super helpful!

Well when I went to use it this morning and it was a little cool in the room it barely moved at all? All the mixes are either 100 or -100

im running out of ideas on this one...

tx settings are all good
servos are centered with the valves
4th valve will close as the others open
it should air itself out...

could it need more oil? i use the texaco rando hdz 32 hydraulic oil..
does it leak much?

some gunk clogging hoses or valveblock?
motor/esc problem?
pump?

maybe you could post some pictures of hydraulic block and the setup.. or video also of operation.
