Caution: Personal injury danger,
i.e., leaking hydraulic oil can penetrate
or burn skin. Wear goggles and
protective gloves.

Leakage of high-pressure oil may be
invisible to eyes, use cardboard or wooden
boards as a search tool for hydraulic oil
leakage. Hands shall be prohibited from
being used for leakage confirmation.
Inspect oil drops or residual oil on the
following components:

Hydraulic oil tank, filter, pump, hydraulic oil
cylinder, motor, reduction gear, valve block
and hydraulic tubing.

Inspect oil drops or residual oil at the
following areas:
Rear of boom, fly jib, upper side of turntable,
upper and lower sides of chassis, and ground
underneath equipment.
1) Test or replace hydraulic oil every 2,000 h
or every two years.
△
!
Caution: If the oil isn’t replaced
after the two year interval, it must be
tested quarterly and replaced when it
no longer passes the testing.
1) Replace hydraulic oil suction filter, oil return
filter and high pressure filter every 500 h or
every 6 months. Replace oil suction filter,
oil return filter and high pressure filter after
first 50 h of use. It is necessary to replace
the hydraulic filter to maintain performance
and service life of the machine. Dirt or a
clogged filter may cause performance
degradation of hydraulic components, and
continuous use will cause damage to
components. In dirty work environments it
is necessary to increase the change
intervals.

Please observe the safety
regulations for engine oil and relevant
local regulations. Dispose of spilled
engine oil and filter elements as
required. Waste oil cannot penetrate
into the ground.
△
!
Test run shall be carried out after
each operation. At the same time, pay
attention to the sealing and lubricating
oil pressure, and then check the
engine oil level.
Check the engine oil level every 8 hours or
every day.
Insufficient or excessive engine oil may cause
