1) Normal braking and brake release function is
essential to proper operation. The brake must
be stable and free of delay, vibration, and
abnormal sounds.
2) Ensure the machine is stowed and the
extending platform is completed retracted.
Complete the braking function inspection on
solid and level ground without any barriers.
3) Make a reference test line on the ground.
4) Turn the key switch to the platform controller
position and pull out the emergency stop
switches on both the ground and platform
controllers.
5) Press the drive function button.
6) Select one point (such as the contact patch of
a tire) from the machine as the visual
inspection reference of the test line.
7) Drive the machine at the maximum speed
and release the handle at the moment when
the reference point passes the ground test
line.
8) Measure the distance between the reference
point and the test line. Result: The machine
has stopped within the specified braking
distance. No action is required. Result: The
machine has not stopped within the specified
braking distance. Repair or replace the brake
and repeat the testing process beginning at
Step1.
1.9.9 B-9 Testing Drive Speed from the
Platform Stowed Position
This check item shall be made once every 25
hours of operation or every month, whichever
interval is shorter.
1) The normal driving function is essential for

proper operation of the machine. The drive
function should respond quickly and
smoothly to operator control. No delay,
vibration and abnormal sound should occur
during the normal operation and driving
function.
2) Complete the driving test on firm and level
ground without any barriers.
3) Draw two lines, spaced by 10m on the
ground, as the starting line and the finishing
line.
4) Turn the key switch to the platform controller
position and pull out the emergency stop
switches from both the ground and platform
controllers.
5) Lower the platform to the stowed position.
6) Press the drive function selector button.
7) Select one point on the machine as the visual
inspection reference point for both the
starting line and the finishing line.
8) Drive the machine at maximum speed and
start to count when the reference point
passes the starting line.
9) Keep driving at the full speed and record the
time when the reference point passes the
finishing line. Refer to the specification.
1.9.10 B-10 Testing Drive Speed from the
Platform Elevated Position
This check item shall be made once every 25
hours of operation or every month, whichever
interval is shorter.
1) The normal driving function is essential for
proper operation of the machine. The
operator should experience a rapid and
stable response. No delay, vibration and
abnormal sound should occur during the
normal operation and driving function.
2) Complete the driving test on firm and level
ground without any barriers.
3) Draw two lines, spaced by 10m on the
ground, as the starting line and the finishing
line.
4) Turn the key switch to the platform controller
position and pull out the emergency stop
switches from both the ground and platform
controls.
5) Press the lifting function selector button.
6) Press and hold the enable switch on the
control handle.
7) Lift the platform for a given height above the
ground as shown in the following table.

10) Drive the machine at maximum speed and
start to count when the reference point
passes the starting line.
11) Keep driving at the full speed and record the
time when the reference point passes the
finishing line. Refer to the specification.
1.9.11 B-11 Low Speed Drive Test
This check shall be made once per 25h or per
month, whichever interval is shorter.
1. Normal drive function is essential to the
proper operation and usage of the machine.
With the drive function, a rapid and stable
response shall be given to the operator. No
delay, vibration and abnormal sound shall
occur during normal operation and drive
process.
2. Complete the driving test on a solid and level
ground without any barriers.
3. Draw two lines10m apart, as the starting line
and the ending line on the ground.
4. Switch the key switch to the platform
controller position and pull out the red
emergency stop buttons from the ground and
platform controllers.
5. Lower the platform to the stowed position.
6. Press the drive speed selector button.
7. Select one point (such as the contact patch of
a tire) from the machine as the visual
inspection reference for the starting line and
the ending line.
8. Drive the machine at maximum speed and
start to count when the reference point
passes the starting line.
9. Keep driving at the full speed and record the
time when the reference point passes the
finishing line. Refer to the specification.
1.9.12 B-12 Visual Inspection of the
Hydraulic Oil
This check item shall be made once every 25
hours of operation or every month, whichever
interval is shorter.
Collect a sample of hydraulic oil and place in a
clear container. Visually inspect the hydraulic oil
for the following:
1) Color: Oil should be a clear, light-honey
colored.
2) Appearance: Oil should be clear and not
cloudy or visibly distorts the view through the
sight glass or container.
3) Contains no particles, foreign objects, or
other contamination.
4) The hydraulic oil can be inspected by smell
(can smell “hot” but not “burnt”) or rubbing
between fingers (should feel viscous and free
of any rough feel due to particles) If the
hydraulic oil passes all of the above
inspections, continue the scheduled
maintenance intervals. If the hydraulic oil fails
any of the above inspections, the hydraulic oil
must be tested by an oil distributor or
replaced.
Note: If the hydraulic oil has not been replaced for
two years, the oil must be tested every quarter by
an oil distributor until the oil fails the test and is
replaced. After the oil has been replaced,
continue the scheduled monthly maintenance
inspection.
