Keep And Maintenance - Hyundai 15EPML Operation Manual

7. Keep and maintenance

Whether the truck can serve satisfactorily depends on careful maintenance. Neglect of
maintenance may harm human body and damage cargo. Therefore, when you use the truck,
please conduct inspections timely, exclude abnormal phenomenon, and never use a faulted
truck in order to ensure safety and prolong service life.
Maintenance: maintenance of the truck is divided into three levels, i.e. daily maintenance,
first level maintenance and second level maintenance.
Daily maintenance: conducted daily, mainly to keep truck surface clean and check
whether power wire is damaged.
First level maintenance: conducted weekly, mainly to check whether each component
functions normally, whether each fastener is fixed, whether there is leakage, whether the
mechanical part has abnormal wearing and whether the electrical part has abnormal
temperature rise or sparks. For any abnormal phenomena, adjust and exclude timely.
Second level maintenance: conducted periodically, and conduct full inspections for the
following aspects:
a. Mechanical maintenance: conducted half a year, mainly to check whether any fastener
becomes loose, whether each wheel turns flexibly, and whether forks can lift and lower
normally. After maintenance, the running noise shall not exceed 75dB.
b. Hydraulic maintenance: conducted annually, mainly to check whether oil cylinders are
normal, whether there is inner or outer leakage, whether hydraulic oil is clean, and replace
hydraulic oil every 12 months generally. Adopt ISO oil quality for hydraulic oil.
When ambient temperature is -5 ~ 40℃, adopt L-HV32; when ambient temperature is -
10 ~ -5℃, adopt L-HV15 low temperature hydraulic oil. The replaced wasted oil shall be
disposed according to local laws and regulations. Check whether limit valve works normally.
c. Electrical maintenance: conducted every three months, to check whether each joint is
reliable, whether switches are normal, and whether insulation is normal (insulation resistance
between electrical part and truck body shall be greater than 0.5M ).
