5.3 Basic operations
Main power source and safety
1
）
The key switch supplies power to the
emergency stop switch and the selector
switch on the chassis or platform. The
power will be cut off when the key switch is
in the middle position, and the machine
remains in the selected operating mode
when the key is removed at any of the three
positions.

）
Both the chassis and the platform control
unit are provided with emergency stop
switches, which are connected in series
and must be pulled out before normal
operation. Pressing any of the emergency
stop switches on the chassis or the platform
will cut off the power. The safety function is
based on a complete circuit, which will be
disconnected after pressing any emergency
stop switch.

）
The enable switch on the handle must be
pressed before operating the traveling,
steering, lifting or lowering function.
Lifting and safety
1) The tilt switch on the chassis indicates if the
chassis is level.
2) The load may not exceed the rated load of
the machine of the model.
3) The platform can be lifted or lowered from
two positions: on the chassis or on the
platform. The key switch is used to select
from which position to operate.
4) At the chassis position, only the lifting or
lowering of the platform can be operated by
the ECU button.
5) At the platform position, the operator on the
platform is allowed to select the lift mode.
The lifting/lowering and speed can be
controlled by moving the handle. The
platform will be lifted when moving the
handle backward and will be lowered when
moving the handle forward.
6) If there is a load sensing option among the
function options, the electronic control unit
(ECU) on the chassis will sound and alarm
and prohibit the operation when the
platform is overloaded.
7) If there is a fault in the lifting or lowering
valve, an error code will be displayed on the
PCU's LED and the ECU's LCD.
Traveling and safety
1) Traveling can only be controlled by the
handle on the PCU, and the key switch
should be set at the platform position.
2) If you want the machine to travel, you must
select the travel mode and press the enable
switch on the handle.
3) Move the handle forward and backward to
control the travel direction and speed.
4)
You can select “High speed” or “Low speed”
only when the platform is in the retracted
state. However, when the platform is in the
lifted state (beyond the lower limit), the
machine can only work at the “speed after
lifting”.
5) If the platform is overloaded, no lifting
operation will be allowed.
Steering and safety
1) The key switch must be set at the platform
position.
2) Steering can only be controlled by the left
and right buttons on the top of the handle
on the PCU.
3) If you want to turn the machine, you must
select the travel mode and press the enable
switch on the handle.
Other operations
1) When lifting or traveling, the timer on the
chassis will work.
2) The left two-digit LED on the PCU is used
to display the battery status and the right
two-digit LED is used to display the system
status or error code.
Operation at low battery level
1) The battery level status is determined by
the operator setting the battery level and
the battery level bars are displayed on the
PCU.
2) Normal traveling will be allowed when there
are two or more battery level bars.
3) The traveling speed will be decelerated
when there is one battery level bar
