10 FUNCTIONS AND CONTROLS
10.1 MACHINE POSITIONS
The machine positions/states covered in this manual
are stowed position, transport position, operating posi-
tion, and non-operating position. Each position is de-
scribed in detail below:
• Stowed position: the scissor arms are fully
retracted.
• Transport position: the scissor arms and the plat-
form extension are fully retracted.
• Operating position (elevated): the scissor arms
are elevated until disengaged from the down limit
switch.
• Non-operating position: the scissor arms are not
disengaged from the down limit switch.
Notes: when the scissor arms are disengaged from the
down limit switch, the platform height (from the ground
to the platform floor) shall be: 2.3±0.3 m (7 ft 7 in±12 in).
10.2 DRIVE FUNCTION
Driving at a speed that is appropriate for the given cir-
cumstances is essential for ensuring machine safety.
The drive function should respond quickly and smoothly
to the operator’s control inputs. Travel operation should
be normal, without vibration, impact, and abnormal
noise across the full controllable speed range. To en-
sure proper functioning of the drive system and to check
its condition, it is recommended to check the drive func-
tions every 3 months or every 250 hours of operation.
Select a flat, level, unobstructed and solid surface to
perform the following tests with the stowed platform car-
rying one person:
1. Mark two straight lines on the ground at a distance
of 30 m (98.4 ft) from each other as the test start
and stop lines.
2. Start the machine.
3. In the travel and steer mode, press and hold the en-
able button on the joystick and push the joystick for-
ward to the full drive position.
4. Ensure the machine is traveling at high speed when
the front wheels touch the test start line, start timing.
5. Keep the machine running at high speed. Stop the
timer when the front wheel touches the test stop
line.
6. Calculate the travel speed using the measured data,
and compare it with the specified maximum travel
speed in stowed position.
NOTICE
If the result exceeds the maximum stowed travel
speed by 10 % or more, turn off and tag the machine,
and contact a qualified service technician for
inspection and repair.
10.3 BRAKE FUNCTION
Proper functioning of the brakes is essential for the safe
operation of the machine. The brakes should respond to
the operator’s control inputs quickly and smoothly with-
out any abnormal noise. To ensure proper brake func-
tioning and to check their condition, it is recommended
to check the brakes every 3 months or every 250 hours
of operation.
Ensuring the machine's braking distance is within the
normal range is an important indicator of the braking
function being normal. Select a flat, level, unobstructed
and solid surface to perform the following tests with the
stowed platform carrying one person:
1. Verify that the machine’s brakes have not been
released.
2. Mark a test line on the ground as a reference.
3. Start the machine.
4. In the travel and steer mode, press and hold the en-
able button on the joystick and push the joystick for-
ward to the full drive position.
5. Ensure the machine is traveling at high speed when
the front wheels touch the test start line, then re-
lease the joystick quickly.
6. Measure the horizontal distance between the test
line and the contact point between the front wheel
and the ground, which is the braking distance.
7. Compare the measured distance with specified
braking distance at full travel speed.
