Annual Maintenance Procedures
Oscillate Float Test
Note: The following procedure will require two
people.
13 Using a volt meter, check for voltage by
connecting the positive lead to terminals D2,
D3, D4 and D5. Connect the negative lead to
the ground strip terminal. Slowly move the
drive controller just off center.
Crushing Hazard. Stay clear of
the machine when performing
this procedure. Movement of the
machine could result in death or
serious injury.
Result: The volt meter should read 12V DC or
greater.
Result: The volt meter reads 0V DC. Do not
proceed. Contact Genie Product Support for
assistance.
Test the Oscillating Axle Limit Switches
14 Using the jumper wire, jump from relay K12,
terminal 87A to terminal D3 below the white
wire.
Result: The right steer end oscillate cylinder
will extend causing the machine to tilt towards
you. This simulates closing the left rear limit
switch causing the right oscillate cylinder to
extend.
Result: No movement. Verify there is voltage
on the jumper wire. Check for voltage on relay
K12, terminal 30.
Oscillate operates in the incorrect direction.
Do not proceed. Contact Genie Product
Support.
Note: Remove the jumper wire from relay K12 and
terminal D3 after the limit switch activates the
oscillate in the opposite direction.
54
15 Using the jumper wire, jump from relay K12,
terminal 87A to terminal D4 below the blue
wire.
Result: The left steer end oscillate cylinder will
extend causing the machine to tilt away from
you. This simulates closing the right rear limit
switch causing the left oscillate cylinder to
extend.
Result: No movement. Verify there is voltage
on the jumper wire. Check for voltage on relay
K12, terminal 30.
Oscillate operates in the incorrect direction.
Do not proceed. Contact Genie Product
Support.
Note: Remove the jumper wire from relay K12 and
terminal D4 after the limit switch activates the
oscillate in the opposite direction.
16 Using a volt meter, check for voltage by
connecting the positive lead to relay K12,
terminal 87 and connecting the negative lead
to the ground strip terminal.
Result: The volt meter should read 0V DC.
Result: The volt meter reads 12V DC or
greater. Check terminal 86 for voltage. If yes,
the drive controller is activated or the ECU
needs to be replaced.
17 Move the drive controller just of center in a
safe driving direction.
Result: The volt meter should read 12V DC or
greater.
Result: The volt meter reads 0V DC. Do not
proceed. Contact Genie Product Support for
assistance.
