lift cyl. works when aux function use

hi folks,
I have a raymond reach truck EZ-C. My problem is that lift cylinder goes up when i use the aux functions both retract in/out, sideshift and tilt. This was happened when we replaced a new hyd. pump. But as we test the unit in a couple minutes the unit sames alright, back on its normal operation. This problem was occurred in around 20 minutes testing and after that back on normal.
I suspected that the air intake into the hyd system triggered this problem. I am not sure for now where the problem is. If anyone have an idea or encountered same problem from this unit?. Please, ideas and suggestions will be appreciated.
Thank you so much in advance! and God Bless us all!

Hey JonG thanks for the reply. I'm not sure if its the control handle. I'm the one who repair this unit. The Problem came in when i replace the new hyd. pump. BUt now the unit runs fine everything is ok. I'm just wondering that why does the lift cylinder goes up when i triggered the auxiliary functions. This unit has a lift lock when you use the auxiliary functions.

Thank you for the reply........:-)

I would test the control handle. Normally when you see these issues the cable from the handle to the card has been crushed and is shorting.. you may see it come and go - typically because the operator is leaning on the cover etc.
