Notes: If the machine is equipped with an integrated slewing bearing (including both the slewing drive unit and
the slewing bearing) to perform the slewing movement, just conduct an inspection and lubrication as per
requirement No. 3 in the table.
Lubrication intervals are based on machine usage under
normal operating conditions. If the machine is used in
rough (such as dusty environments) or other unusual
conditions, inspection and lubrication should be per-
formed more frequently.
10.2 OIL REQUIREMENTS
NOTICE
• Please choose suitable oil according to the ambi-
ent temperature and local regulations; the use of
unsuitable oil will damage the machine
components.
• Oils of different grades or viscosities should not be
mixed. The oil being added must be of the same
grade and viscosity as that of the oil currently in
use in the machine.
• For special environments or special operating re-
quirements please contact Sinoboom.
• Before refilling oil, wait until the temperature
of the machine drops to room temperature,
otherwise it may cause splashes, burns or oth-
er personal injury.
• The use of inferior oils is strictly prohibited.
Using inferior oil may damage the machine,
and faults caused by this are not covered by
Sinoboom’s warranty.
Hydraulic oil
Factory-filled hydraulic oil is usually L-HV32 or L-HM46
or as specified by customers. Different regions have dif-
ferent temperature environments, so please select the
hydraulic oil suitable for your region according to the
recommendations in the table below.
