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.

9A-3: Check the cylinder by feeling the shaft of the
cylinder and pulling up and down on the left
treadle. If the cylinder shaft moves in and out of
the cylinder body by more than an 1/8th inch (3.2
mm), then the cylinder will need to be replaced.
9A-4: If the problem is not in the cylinder, then check the
hardware at the following locations and tighten as
necessary:
a) On the rod-end entering the cylinder, the jam
nut should be tight to the rod-end, and there
should only be 2 or 3 threads showing on the
opposite side of the jam nut. This insures that
the rod-end is fully engaged in the cylinder.
b) The connection between the rod-end and the
dependency weldment. See Figure A-6. Tighten
as necessary.
c) The connection between the dependency and
the rod-end on the opposite (right) side (see
Figure A-4 and A-5).
d) The center bolt at the center of the dependency
weldment (see Figure A-6).
e) Check both the horizontal and the vertical bolts
connecting the cylinder to the coupler and the
coupler to the weldment of the pan. The bolts
should be torqued to 75 ftlbs (105 Nm). See
Figure A-7.

B:
IF THE PROBLEM IS NOT IN
THE HYDRAULIC CYLINDER OR
THE CONNECTING HARDWARE,
THEN PERFORM THE FOLLOWING
ELECTRONIC AND SOFTWARE
CHECKS:
9B-1: Turn the unit on. Move the treadles up and down
until they come to a locked position.
9B-2: If the treadles do not come to a locked position
within 2 to 4 steps, then position the treadles level.
Turn the power off. Wait 10 seconds, then turn the
power on. Move the treadles up and down until they
come to a locked position.
9B-3: If the treadles still do not come to a locked position,
then check the treadle center position on the encoder
PCB, as follows:
a) Remove the rear step. Enter diagnostic mode.
From the Intro screen, press [Speed UP] [6]
[ENTER]. The display will read “DIAGNOSTIC”.
b) Press the [Speed UP] or [Speed DOWN] keys
to scroll through the options until “TREADLE
CENTER” is displayed. Press [ENTER]. This will
release the treadles to allow them to be moved
by hand.
c) Slowly move the treadles up and down while
looking at the encoder PCB mounted in the center
of the dependency mechanism. There is a light on
the PCB. Note the position of the treadles when
the light on the PCB comes on. The treadles
should be parallel within 1 inch (2.5 cm) of each
other when the PCB light comes on (see Figure
B-1).
d) If the treadles are not parallel when the encoder
PCB light comes on, then the large encoder wheel
will need to be adjusted. Go to section C of this
section in the Service Manual to re-center the
encoder wheel. Be sure to verify that the large
encoder wheel is firmly fixed to the dependency

value, which is on the lower line center position,
will change from 255 to 189, and the treadles will
be free to move up and down.
9D-3: Shift your weight to the left side, allowing the left
treadle to fall all the way to the bottom. With the
left treadle held at the bottom, note the number
displayed on the top line, far right. It should read
in the range between [ - 30 ] and [ - 50 ]. Remem-
ber the number.
9D-4: Next, shift your weight to the right side, allowing
the right treadle to fall all the way to the bottom.
The number displayed on the top line, far right
should read in the range between [ 30 ] and [ 50].
Remember the number.
9D-5: Calculate the total range between the two num-
bers. The absolute value of the negative number
(left side down) added to the positive number (right
side down), represents the total encoder range
of motion. This number should be in the range
between 70 and 90 total counts.
9D-6: If the range is less than 70, check to make sure the
large encoder wheel is not slipping.
Figure D-1
To check if the encoder wheel is slipping, slowly move the treadles up and down. The encoder value
displayed will hesitate and not count up or down. In other words, the encoder value will not change, even though
there is movement in the treadles. If the encoder value does not change during movement of the treadles, then
the encoder wheel is slipping and needs to be tightened or replaced.

TO RESET THE TREADLE CENTER
IN SOFTWARE TO MATCH THE
TREADLE CENTER ON THE
ENCODER, FOLLOW THESE STEPS:
9E-1: From the Intro screen, press [Speed UP] [6]
[ENTER]. The display will read “DIAGNOSTIC”.
Press the [Speed UP] or [Speed DOWN] keys
to scroll through the options until “TREADLE
CENTER” is displayed. Press [ENTER].
9E-2: The top line of the display will read: “VIRTUAL
CENTER - XX” (see Figure E-1). With the treadles
held parallel, press the [STOP] key. The number
on the display will be used by the software for the
center point position. When STOP key is pressed
the number will change to a value between 0
to 255. This means the treadle center in the
software has been recalibrated to match the
center position of the encoder.
9E-3: Press [CLEAR] twice to exit the Diagnostic mode.
Move the treadles up and down until the treadles
lock. Verify that the treadles lock parallel to each
other or within 1” of parallel.
9E-4: If the treadles do not lock parallel or close to
parallel, then 1) recheck the center position on the
encoder PCB (section B); 2) recheck the encoder
range (section D); 3) recheck the treadle center in
software (section E).
