Mycenter3 pallet changer proablem

[MBecker]

I have a mycenter3 with a pallet changer, it has worked just fine in the past, but today i am having some trouble. The table won't unclamp with a m79 command, I called kitamura and they said to use a g23 command. When i use the g23 i get a ps10 alarm for insuficant g code. Anyone have any suggestions to help me out?
thanks

is there hydraulic fluid and air pressure if so your switch must have dirt in it
it is located on the X axis saddle under the way covers

Hello There,... i'm having a similar issue with a Kitamura MY-0 Sparkchanger Pallet,.. is it possible to remove, open up, and clean the HE-4 pressure switch or should i order a new one,.. a new HE-4 is $630.00 and with cash a little tight i would prefer to repair,.. or if anyone has the cross-reference part number and place to order where its cheaper that would be great.
Thanks
Buddy
