9.0 - TREADLE ADJUSTMENT
TROUBLESHOOTING
Parts Affected:
• Treadle Assembly
• Hydraulic Cylinder
Tools Needed:
• Phillips Screwdriver
• Hex Key
• Socket Wrench
• Flat Screwdriver
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.
