Just the flaps leaves fluid in the bottles and you get an inaccurate reading reading on one bottle. =C2-Just my 2 cents worthTony=C2- On Saturday, June 24, 2017 1:07 AM, William Geipel w rote: Always the micro Sw. Normal system fills all. Make sure tank is full. Might take a long time to bleed off pressure. Fill it up within in an inch of the top of the filter screen. Run the engine at 80% and hold that handle while actuating the speed brakes . Let the hyd pressure gauge go all the way up and back to zero, then retract the speed brakes and let the needle go up then back to zero wh ile holding the handle forward. Takes about 4-5 times/ Never let go of the handle, I might suggest that when servicing the hydraulic system at the annual insp ection, be sure the accumulators have the nitrogen pre-charge of 50 ATM in each bottle. Bottles must be completely empty of pressure before checking pre-charge. Op en flap extension emergency valve and drain completely until accumulator pr essure is zero. Lots of fluid and air out the right wing drain valve. > On Jun 23, 2017, at 16:17, RJM wrote: > > > Hi Bill, > > Well we found the micro switch that wasn't working.=C2- Next to impossi ble to remove so we sprayed it with cleaner and been exercising it regularl y.=C2- It now appears to be consistently working.=C2- Time will tell... > > One more question...does the 2.6l of fluid for the emergency side come fr om the main hydraulic tank, or are the accumulators filled separately somew here with fluid?=C2- Does this happen with the Accu Fill lever or is that air only? > > Multiple manuals but no real concise answer. > > Thanks, > > > > > Read this topic online here: > > http://forums.matronics.com/viewtopic.php?p=470426#470426 > > > > > > > > > S - WIKI - - =C2- =C2- =C2- =C2- =C2- -Matt Dralle, List Admin. ------------------------------------------------------------------------------------- Other Matronics Email List Services ------------------------------------------------------------------------------------- Post A New Message l29-list@matronics.com UN/SUBSCRIBE http://www.matronics.com/subscription List FAQ http://www.matronics.com/FAQ/L29-List.htm Web Forum Interface To Lists http://forums.matronics.com Matronics List Wiki http://wiki.matronics.com Full Archive Search Engine http://www.matronics.com/search 7-Day List Browse http://www.matronics.com/browse/l29-list Browse Digests http://www.matronics.com/digest/l29-list Browse Other Lists http://www.matronics.com/browse Live Online Chat! http://www.matronics.com/chat Archive Downloading http://www.matronics.com/archives Photo Share http://www.matronics.com/photoshare Other Email Lists http://www.matronics.com/emaillists Contributions http://www.matronics.com/contribution ------------------------------------------------------------------------------------- These Email List Services are sponsored solely by Matronics and through the generous Contributions of its members.
