troubleshooting treadle Steps:

a: 

 DetermInInG If there IS a 
proBlem WIth the hyDraulIc 
cylInDer (eIther aIr In the 
SyStem or contamInantS In 
the oIl anD valveS), or In the 
connectInG harDWare:

NOTE:

  Two people are required to complete this step. One 

person standing on the treadles, while the other 
person adjusts the encoder.  

9a-1:  

Disconnect the two leads from the hydraulic 
cylinder. This will ensure that the hydraulic cylinder 
valve should be closed (see Figure A-1).

  

 9a-2:   

With the treadles in the locked position, pull up 
and down on both the right and left treadles (see 
Figure A-2).

 

   If the right treadle is loose (moves more than ½”) 

and the left treadle is solid, this points to loose 
hardware.  Go to Step 9A-4 in Section A.

 

    If both right and left treadles are loose, then 

the problem could be loose hardware or a bad 
cylinder.
