5. The platform should be down into place.
B-8 Inspect Braking Device
Braking device must operate smoothly and be in good
condition for safe and proper operation of the machine.
Do not operate the machine if the brakes make a
grinding sound or other abnormal noise. The machine
is braked by the front wheel.
1. The machine carries one person only and is fully
stowed.
2. Turn the key switch to the platform control position.
3. Operate the control handle to drive the machine on
flat pavement at maximum speed. Then release the
handle rapidly.
4. Measure the braking distance of the machine.
Result: The braking distance must be less than
0.4m（1ft 3.7in）.
NOTICE
The braking device must be able to hold the
machine firmly on the maximum slope the
machine can climb.
5. The machine is fully loaded and raises to full height.
6. Operate the control handle to drive the machine on
flat pavement at maximum speed. Then release the
handle rapidly.
7. Measure the braking distance of the machine.
Result: The braking distance must be less than
0.1m（4in）.
B-9 Test Lift/Lower Speed
Appropriate lifting or lowering speed is important for the
safe operation of the machine. The lifting/lowering
function must be able to respond to the actions of the
operator rapidly and stably, without swinging, impact
and abnormal noise.
UNSAFE OPERATION HAZARDS
With the machine parked on firm
level surface and in no-load state,
operate the platform controller to lift/
lower the platform.
1. Using the platform controller, lift the platform from
stowed state to full height.
2. Measure the lift speed (the time for the platform to
lift to full height)：24～28s.
3. Using the ground controller, lower the platform from
full height to stowed state.
4. Measure the lower speed(the time for the platform
to lower to stowed state)：22～26s.
B-10 Test Drive Speed
Driving the machine at a reasonable speed is essential
to safe machine operation. The drive function should
respond quickly and smoothly under the control of the
operator. The machine should drive within its entire
speed range free of vibration, impact or abnormal
noise.
1. Pull out the emergency stop buttons on the ground
and platform controllers to the ON position.
2. Turn the key switch on the ground controller to the
platform control position.
Low speed test:
3. —SINOBOOM system: After turning the lift function
enable switch on the platform controller upwards,
the indicator light should come on.
—DTC system: After pressing the lift function
enable button on the platform controller, the
button should come on.
4. Hold the enable switch on the control handle and
deflect forwards to activate the platform lift function.
Raise the platform to the operating position.
5. —SINOBOOM system: After turning the drive/steer
function enable switch on the platform controller
downwards, the indicator light should come on.
Hold the enable switch on the control handle and
slowly deflect forwards to full drive speed. The
