Traction Pedal Adjustment (continued)
Electrical System: Adjustments
A. Voltage in full reverse should be from 0.5 to 1.75V (approximate).
B. Voltage in full forward should be from 3.5 to 4.5V (approximate).
5. If voltage range from full reverse to full forward is incorrect, adjustment of the
spring shaft and rod end bearing is necessary
A. Loosen hex nut that secures rod end bearing in spring shaft. Hex nut can
be accessed through slot in frame bracket next to traction pedal.
B. Use hex on front end of spring shaft to rotate spring shaft which changes
traction pedal position in relation to traction pedal position sensor. The
spring shaft hex nut can be accessed from below the machine.
C. Check range of voltage as described in step 4 above and make
additional adjustments to the spring shaft until range of voltage is within
specifications.
D. Tighten hex nut to secure rod end bearing in spring shaft. Check that
traction pedal range of voltage is still correct after hex nut is tightened.

display Neutral as ON and both Forward Range and Reverse Range
as OFF.
B. Move traction pedal in the forward direction and the InfoCenter should
display the Forward Range as ON and both Neutral and Reverse Range
as OFF.
C. Return the traction pedal to neutral and then move pedal in the reverse
direction. The InfoCenter should display the Reverse Range as ON and
both Neutral and Forward Range as OFF.
D. If outputs are incorrect, additional adjustment of the spring shaft and rod
end bearing are necessary.
7. After completing all adjustments and before returning the machine to
operation, calibrate traction pedal position sensor (see
