Green
Measure the voltage of each
battery. If the voltage is lower
than 11V, it indicates that the
battery is damaged; The voltage
is between 12.4v-12.7, indicating
that the battery is in good
condition

If the color of the battery hydrometer is
green and the voltage is above 12V, but
the starter cannot be driven, please ask
the personnel trained and qualified for
the maintenance of the machine to
further test the battery.
Battery recharge:

Before charging, disconnect the
negative connection of the battery first,
and then the positive connection of the
battery.

Before replenishing electricity, clean the
end column and remove the oxide scale
on the surface.
△
! Note: If an external power
supply is required to charge the
battery, only the charger approved
by the LGMG can be used.

Do not replenish the battery with
white eyes. Replace the battery.

When wiring after charging,
connect the positive wire first and
then the negative wire.

! Notice: Adding a terminal
protector and an anti-corrosion sealant
will help remove corrosion caused to
battery terminals and cables.
1.8 Check for tires and hubs
This check item is conducted every 200 hours or
two month, whichever comes first.
Keeping tires and hubs in a good condition is
critical for safe operation and good performance.
Failure of the tires and hubs may cause the
platform to tilt. If such failure is not found and
repaired in time, it will also cause damage to
platform parts.
1) Check treads and sides of tires for scratches,
cracks, punctures, and other abnormal
wear.
2) Check if the hubs are damaged, bent or
cracked.
3) Check whether or not the technological
screws for tires are detached. Upon the
detaching of screws, if there is slight or no
leakage of fillers, and no significant
deformation is found for the tire body, and
users can knock in screws which are
slightly larger than the diameter (about
5mm) of the vent hole with a hammer. If
leakage of a large quantity of fillers is found,
and the tire body deforms significantly, it is
necessary to reduce the height of the
working platform and replace the tires
timely.
4) Check for nut torque of tires

1.9 Check for exhaust cover
of hydraulic oil tank
1) This check item shall be conducted every
250 hours or quarterly, whichever comes
first.
2) An unobstructed hydraulic oil tank cap is
essential for good mechanical performance
and long service life of the platform. A dirty
or clogged exhaust cover may result in poor
platform performance. Given harsh working
environment, more frequent check is
required.
①
Remove the exhaust cover from the
hydraulic oil tank cap.
②
Check for ventilation.
Result: Air can pass through the exhaust cover.
Result: If air does not pass through the exhaust
cover, clean or replace the exhaust cover.
Continue with Step 3.

Notice: Air is supposed to pass
freely while checking ventilation of the
oil tank cap.

Carefully clean the tank exhaust cover with
mild solvent and dry it with low pressure
compressed air. Repeat Step 2.
