MAINTENANCE
BODILY INJURY HAZARD
Lead-acid batteries and lead-acid
maintenance-free batteries contain
acid. Avoid acid overflow or contact
with acid in lead-acid batteries and
lead-acid maintenance-free batteries.
If battery acid spills, use water mixed
with bicarbonate (baking soda) to
neutralize the acid.
NOTICE
After the battery is fully charged, wear protective
gloves for inspection.
Ensure the connection of the battery cable is not
corroded.
Ensure the battery is firmly in place and the cable
wiring is fastened.
NOTE: Add wiring end protectors and antiseptic
sealants to help eliminate corrosion of the battery
terminals and cables.
NOTE: Be sure to fully charge the battery before
testing.
There are three types of batteries: lead-acid battery,
lead-acid maintenance-free battery and lithium
battery. Lithium battery and lead-acid maintenance-free
battery are maintenance-free batteries.
INSPECT THE LEAD-ACID BATTERIES
• Wear protective clothing and goggles properly.
• Ensure that the connections of battery cable are not
corroded.
• Ensure that the battery is installed properly and the
cable connections are tight.
• Open the vent caps and test the density of the
electrolyte of individual battery cells with a liquid
density tester.
Result: Replace the battery if the electrolyte density
of any battery cell is below 1.026.
• Inspect the electrolyte level. Add distilled water if the
level is low. Do not overflow.
• Install the vent caps
• Connect the battery charger cable to the correct
post on the battery (red to positive, black to
negative).
• Connect the charging plug to 220V socket.
Result: The battery should be recharged normally,
and the charge indicator should illuminate.
INSPECT THE MAINTENANCE-FREE
BATTERIES
• Wear protective clothing and goggles properly.
• Ensure that the connections of the battery cable are
not corroded.
• Ensure that the battery is installed properly and the
cable is connected tightly.
• Connect the battery charger cable to the correct
post on the battery (red to positive, black to
negative).
• Connect the charging plug to 220V socket.
Result: The battery should be recharged normally,
and the charge indicator should illuminate
B-4 Inspect Hydraulic Oil
Inspecting and replacing the hydraulic oil is important
for the proper operation of the machine and the exten-
sion of service life. The machine may be unable to oper-
ate properly if the hydraulic oil becomes dirty, and the
hydraulic parts may be damaged if using contaminated
oil. Replace the hydraulic oil often, especially when the
service environment is very dirty.
NOTE: Due to wear and tear on the mesh components,
metal particles may appear in the hydraulic fluid or filter
of the new machine.
BURN HAZARD
Before maintaining the hydraulic sys-
tem, allow the hydraulic fluid to cool
to room temperature.
Replace the hydraulic oil if any of the following condi-
tions exist.
• The hydraulic oil is milky white and cloudy.
• The hydraulic oil is blackened.
• Obtain a sample of the hydraulic oil and inspect it in
sunlight. Rub the oil between two fingers to deter-
mine if it contains metal particles.
• The hydraulic oil has an abnormal smell.
See D-4 Inspect and Replace Hydraulic Oil, page 4-
19 for replacement steps.
B-5 Inspect Hydraulic Oil Tank
Ventilation System
Good ventilation of the hydraulic oil tank cap is
important for the proper operation of the hydraulic
