TECH TIPS
Step 1
Make sure the boom is in the fully retracted position, the lower
emergency stop button is pulled out and the off/ground
controls/platform controls keyswitch is in the platform controls
position.
Move the boom if necessary to an area where there will be
enough room to fully retract and extend the axles.
Step 2
At the platform controls pull the emergency stop button out.
Start the engine and depress the foot pedal and fully retract
the axles by depressing the axle retract button.
At this time the engine may be shut down.
Leave the emergency stop button out.

TECH TIPS
If either the front axle angle sensor or rear axle angle sensor
are not within the specified 4.2 to 4.4 volts the "turtle shell"
must be adjusted to get the sensor within range.
To adjust the "turtle shell" back off the 1/4" mounting bolts
enough to rotate the "turtle shell" until the reading on the
multimeter is within 4.2 and 4.4 volts.
When the adjustment has been made tighten the 1/4"
mounting bolts to secure the "turtle shell".
Step 4
In the left and right lower side trays on the boom chassis you
will find a 4 pin Deutsch connector coming into the cabinet from
the axle position sensors.
With your multimeter check for voltage between pin 2 (green/
white) and pin 3 (black) for voltage between 4.2 and 4.4 volts
on both the front and rear Deutsch plugs.
Note: If you have a computer with WEB GPI connected at
TCON these voltages may be checked in the axle runscreen.
If the front and rear sensor voltages are within the specified
voltage you may proceed to step 5.
Step 3

TECH TIPS
The display will change to "AXLE ANGLE SENSOR FULLY
EXTENDED NO/YES"
Start the engine from the ground controls and put the off/
ground controls/platform controls keyswitch in the platform
controls position.
NOTE: If the display changes and is no longer displaying "NO"
put the keyswitch back into the ground controls position and
push the PLUS - ENTER - ENTER - PLUS buttons again and
use the ENTER button to return you to the "AXLE ANGLE
SENSOR FULLY EXTENDED ON/YES" display. Put the
keyswitch back in the platfrom controls position.
From the platform controls fully extend the axles.
Leave the engine running.
Step 6
At the ground controls put the run/service bypass/recovery
keyswitch in the service bypass position.
Put the off/ground controls/platform controls keyswitch in the
ground controls position.
While holding the ENTER button pull out the ground controls
emergency stop button.
Press the following buttons in this order: PLUS - ENTER -
ENTER - PLUS
Use the enter button to scroll through the menu to "RESET
A
XLES ANGLE SENSORS YES/NO"
With the PLUS button change the display from NO to YES.
Press the ENTER button to save the change.
The display will change to "AXLE ANGLE FULLY
RETRACTED YES/NO".
With the PLUS button change the display from NO to YES.
Press the ENTER button to save the change.
Step 5

TECH TIPS
Check the axle indicators at the platform controls.
When the axles are fully extended the indicator light should be
on solid.
When the axles are fully retracted the indicator light should be
on solid.
Any time the axles are between the fully extended and fully
retracted positions both indicator lights will be flashing.
If more diagnosis is needed contact the Genie Service
Department at 1-800-536-1800
Step 8
At the ground controls put the off/ground controls/platform
controls keyswitch in the ground controls position.
With the PLUS button change the display from NO to YES.
Press the "ENTER" button to save the change.
Continue to scroll through the menu by using the "ENTER"
button until the display reads "EXIT NO/YES"
Use the PLUS button to change NO to YES.
Hold the start button for 5 seconds or until the engine shuts
down.
A beep will be heard and the new data has been saved.
Return the run/service bypass/recovery keyswitch to the run
position.
