Oscillating Axle
How the Oscillating Axle
Functions
When driving the GS-69 with the platform in the
stowed position, the oscillating axle function
ensures that all four wheels maintain solid contact
with the ground, delivering the maximum traction
available.
When driving the GS-69 with the platform raised
above the down limit switch height, the oscillating
axle function is limited in that the oscillating
cylinders only respond to input from the oscillating
axle limit switches, located on the rear axle.
When the platform is stowed, safety controller
send 12V input power to the ECM (U5) , connector
J2-A2 and relay CR9 terminal 30. 12V input power
is cut to ECM (U5) , connector J2-A1.
When the platform is raised above the down limit
height, safety controller cut power to ECM (U5),
connector J2-A2 and CR9 terminal 30. 12V input
power is sent to ECM (U5), connector J2-A1.
Oscillate Stowed Relays CR9 and CR10
When stowed on a flat level surface and the drive
function is enabled, the ECM sends 12V input
power to relay CR9-86 & CR10-30 which energies
the oscillate float valve Y95 allowing the oscillate
cylinders to float.
Oscillate Limit Switches LSALOS, LSALOO
When elevated and driving if load is removed from
the left rear wheel, LSALOS changes state
interrupting power to the ECM (U5), connector J2-
A8 and sends 12V input power to the right oscillate
valve Y94. 12V input power is sent to CR10-
86 cutting power to the oscillate float valve Y95.
LSALOO opens changing the input voltage to
TB39 from 1.38V to 2.5V.
Oscillate Limit Switches LSAROS,
LSAROO
When elevated and driving if load is removed from
the right rear wheel, LSALOS changes state
interrupting power to the ECM (U5), connector J2-
A7 and sends 12V input power to the left oscillate
valve Y93. 12V input power is sent to CR10-
86 cutting power to the oscillate float valve Y95.
LSAROO opens changing the input voltage to
TB39 from 1.38V to 1.91V.
