Controls
Problem Cause Solution
An overweight
warning appears
when the ma-
chine has no
load
The load has not been cali-
brated
 Re-calibrate the load coefficient.
 Lift and lower it several times.
The forward
function fails
without a warn-
ing
The forward moving capabil-
ity is malfunctioning
 Check whether the PWM plug of the
controller on the lower platform is in-
serted correctly and solidly.
 Check whether the connection of the
forward valve is normal.
 Inspect whether the platform control-
ler is malfunctioning.
The backward
function fails
without a warn-
ing
The backward moving capa-
bility is malfunctioning
 Check whether the PWM plug of the
ground controller is inserted correctly
and solidly.
 Check whether the connection of the

 The wiring of the load sensor is incor-
rect.
 The sensor is not in good condition.
The machine

stops intermit-
tently
The battery level is low/the

 Re-calibrate the parameters.
 The battery is out of power. The elec-
tricity meter only can be referred.
After setting, the
parameters
could not be
saved success-
fully after several
trials.
The storage is abnormal
 The parameters cross the line.
