4.6 - OSCILLATING AXLES (IF EQUIPPED)
To improve the driving capability on rough terrain, the front axle is equipped with an oscillating
mechanism. When the extending structure is retracted and is in the stowed position,
oscillating mechanism is unlocked to adapt itself to the features of ground operation. When
the extending structure is out of the stowed position, a safety device locks the oscillating
mechanism to reduce overturning hazard.
A visual inspection must be performed to ensure the absence of leaks from the oscillating
cylinder and associated plumbing connections including the hydraulic hoses.
A periodic inspection of this device must be conducted according to the recommendation in
the maintenance schedule.
4.7 - SLOPE WARNING DEVICE
The slope warning device alerts the operator that the machine is positioned on a slope
exceeding the rated slope. A buzzer sounds at both control positions.
N.B.-:-THE SLOPE SENSOR IS ONLY ACTIVE WHEN THE PLATFORM IS NOT IN THE STOWED POSITION.
When machine is on a slope greater than the rated slope, with extending structure out of the
stowed position :
• DRIVE function is disabled.
• All the lifting movements are cut. Only the lowering / retracting movements are authorized.
In this case, fully lower the platform and reposition the machine on level ground before raising
the platform again.
To restore DRIVE function when machine is on slope with the platform uphill, perform the
following steps before repositioning on level ground :
To check the tilt sensor at ground level, perform the following steps :
Step Action
1 Retract the boom.
2 Lower the arm.
3 Lower the telescoping boom.
Step Action
1
Open the right hand compartment cover (Component location diagrams) and locate the tilt
sensor ( C28 ). Tilt sensor is located on the base plate of turret on the right hand side of the ground
control box.
2 Pull out both E-Stop buttons ( 9 ) at ground box and ( 46 ) at platform box.
3
Set the key switch ( 22 ) at ground box to the position
4 Start the engine by pressing the engine start-up selector ( 16 ) .
