1. Start the machine.
2. Fully raise and lower the platform twice from the
ground controls to ensure that the machine displays
no obvious vibration or abnormalities, and is prop-
erly lubricated.
3. As long as the weight on the platform is less than or
equal to the rated load capacity the platform can be
lifted to its highest position.
4. After lifting the platform to the non-operating posi-
tion, gradually apply load to the platform according
to the rated load capacity of the platform. When the
platform load weight is greater than 1.2 times of the
rated platform load, the buzzer will sound, the dis-
play shows the platform overload fault code “OL”,
the lifting and travel functions will be restricted, but
the platform is only allowed to lower. After the ex-
cess load is removed, all functions will be resumed.
5. After lifting the platform to the operating position,
gradually apply load to the platform according to the
rated load capacity of the platform. When the plat-
form load weight is greater than 1.2 times of the
rated platform load, the buzzer will sound, the dis-
play shows the platform overload fault code “OL”,
and all functions will be disabled.. After the excess
load is removed, all functions will be resumed.
NOTICE
If during the test it is found that the machine's
movements are not restricted as expected, lower the
platform to the stowed position, shut down the
machine, tag it accordingly, and contact qualified
maintenance technicians for inspection and repair.
10.7 STAGED LOWERING
FUNCTION
In order to reduce the risk of crushing and collision with
obstacles while lowering the platform, the machine is
equipped with a staged lowering function to be used
while lowering the platform from the platform controls. It
is recommended to check the staged lowering function
every 3 months or after 250 hours of operation.
Select a flat, level, unobstructed and solid surface to
perform the following tests:
1. Start the machine and raise the platform to the high-
est position.
2. Activate the platform lift mode from the ground con-
trols, press and hold the enable button on the joy-
stick and pull the joystick back. The platform will
lower.
3. Once the platform is lowered to the non-operating
position, the machine will stop lowering
automatically.
4. Release the joystick to the neutral position.
5. Repeat step 2 to re-activate the platform lowering
function, the platform will continue lowering 5 sec
later.
NOTICE
If during testing it is found that the staged lowering
function is not working, immediately lower the
platform to the stowed position, turn off and mark the
machine, and contact a qualified service technician
for inspection and repair.
10.8 EMERGENCY LOWERING
FUNCTION
When the power unit fails, the emergency lowering func-
tion can be used to lower the platform into place. It is
recommended to check the emergency lowering func-
tion every 3 months or after 250 hours of operation.
Test the emergency lowering function as per the Emer-
gency Lowering section in the Operation Manual.
NOTICE
If the emergency lowering function is found to not be
working properly, immediately lower the platform to
the stowed position, turn off and tag the machine, and
contact a qualified service technician for inspection
and repair.
