Steering Relief Valve
1. Remove the top steering hose from back of the manifold and replace it with a 0-250 bar pressure gauge.
2. Block the end of the hose with a cap fitting.
3. Remove the plug from the end of the valve to expose the adjusting screw.
4. With the engine running, push the Steering Switch
RIGHT and set the pressure to 80 bar (1200 psi) max.
5. Replace the valve plug.
6. Remove the gauge and reinstall the hose.

Axle Centre Switch
1. Check tires for proper pressure.
2. Place the work platform on a level surface with the front
and rear axles parallel (on the same plane).
3. Adjust the switch so it is centered in the front axle actuator
linkage. When centered, the switch will close the circuit.
4. Test the switch function by positioning the front axle off-
center and raising the platform 2 m above the ground. The
work platform should not drive. Retest with axle off-center
in the opposite position.
Down Proximity Switch
The down limit switch is a dual proximity switches which
allow the machine to run at HI speed when the platform is
lowered.
1. Raise the platform 30 cm (12 in.) from its’ fully lowered
position.
2. Disconnect the wires at the proximity switches and
connect an ohmmeter or continuity tester.
3. Place a piece of steel across the receiver end to varify
the switch is functioning correctly.
4. Disconnect ohmmeter and reconnect wires.
5. Lower platform.
The tilt sensor has three wires; red-power (12v in), black-ground, white-
output (12v out). To verify the sensor is working properly, there is one LED
under the sensor; red indicates the sensor is out of level and the white wire
is “hot” (12v out).
Setting the Tilt Sensor & Level
1. Level the platform with the platform controls using a digital level to
ensure the platform is level ±1/4°. side-to-side and front-to-back.
2. Adjust the bubble level with the three leveling screws until the bubble
is centered in the circle on the bubble level.
3. The tilt Sensor is located at the rear of the 1st post weldment.
4. Adjust the three leveling locknuts on the tilt sensor until the bubble is
centered in the circle.
