Chapter 11 - Maintenance
• Raise the platform to a height of about 2.3 m above the ground.
• Press the drive function select button.
• Select a point (such as the touchdown point on the wheel) of the machine as the visual inspection reference
for the start and nish line.
• Drive the machine at the maximum speed per hour and start counting when the reference point is the starting
line passes the starting line.
• Keep driving at maximum speed and note the time when the reference point crosses the nish line. See
the specication.
B-10 Test of driving speed-low speed
1) This check must be carried out every 250 hours or every quarter, whichever comes rst.
2) The normal driving function is essential for safe operation. With the driving function, a fast and stable response
must be given to the operator. No delay, vibration and abnormal noise may be emitted during normal
operation and the driving process.
3) Make sure that the driving test is carried out on a solid and level surface without any obstruction.
• Draw two lines on the ground with a distance of 10 m, i.e. the start and nish line.
• Turn the key switch to the platform control and pull the red emergency stop buttons of the ground and
platform operation controls.
• Lower the platform to the collapsed position...
• Press the driving speed selection button.
• Select a point (such as the touchdown point on the wheel) of the machine as the visual inspection reference
for the start and nish line.
• Drive the machine at maximum speed and start counting when the reference point passes the starting line.
• Keep driving at maximum speed and note the time when the reference point crosses the nish line.
The driving time shall not be less than 22.5 s.
B-11 Hydraulic oil analysis
1) This check must be carried out every 250 hours or every quarter, whichever comes rst.
2) Replacing or testing hydraulic oil is essential for equipment performance and service life.
The contaminated hydraulic oil can affect the unit performance and this can lead to damage to the device, if
the oil is still being used. Frequent inspection is necessary for checking the poor work environment.
3) Test whether it is necessary to replace the hydraulic oil with an oil separator.
4) If the hydraulic oil has not been changed for two years, you should test once every quarter. If the test fails,
Replace the hydraulic oil.
5) For testing and changing the hydraulic oil, see E-1.
B-12 Inspection of ventilation system of hydraulic oil tank cover
1) This check must be carried out every 250 hours or every quarter, whichever comes rst.
2) The well-ventilated hydraulic oil-tank valve is essential for good mechanical properties and the lifespan.
The dirty or blocked outlet valve can reduce machine performance.
A frequent inspection is required to check the working environment.
• Remove the outlet from the hydraulic oil tank valve.
