clearly marked to ensure they can be
reinstalled correctly.
Hydraulic System
1. Keep the hydraulic system clean. In case
of metallic or rubber particles in the
hydraulic system, please completely
discharge and flush the entire system at
once.
2. Parts shall be removed or reinstalled on a
clean operation surface. All metal parts
shall be cleaned with incombustible
cleaning agent. Parts shall be lubricated
as necessary for easy assembly.
Lubrication
Please lubricate relevant parts at the specified
interval and use lubricant of the amount, type
and grade recommended in the manual. If no
recommended lubricant is available, consult
local supplier for equivalent lubricant with the
specification compliant with or surpassing the
specification listed.
Battery
Batteries shall be washed with nonmetallic
brushes and sodium bicarbonate and water
solution and then washed with clean water.
Battery terminals shall be applied with
anti-corrosion compound after the batteries are
totally dry.
Lubrication and Maintenance
Refer to “Lubrication Table” in Chapter 1 for
parts and components to be lubricated and
maintained.
2.3 Lubrication and Information
Hydraulic System
1. Contaminants are the primary factors that
impair the hydraulic system. They can
invade through a multiple of manners, for
instance, improper use of hydraulic oil,
entry of moisture, lubricating grease,
metal chip, sealing element and sand
during maintenance or failure of
preheating of the system or leakage of
water inlet pipe of water pump, resulting
in cavitation.
2. Design and manufacturing tolerance
standard for working parts is extremely
strict.
Therefore, even a little
contaminant or foreign matter entering
the system can cause wear or destruction
of parts and consequent operation fault.
Be sure to take preventive measures to
keep the hydraulic oil clean, including oil
in reserve. Filter of the hydraulic system
shall be checked, washed or replaced if
necessary at the interval specified in
Chapter 1 and checked for metal particles
at any time.
3. If hydraulic oil is turbid, it indicates it
contains too much water, which may
cause inorganic matters to grow and
result in oxidation or corrosion. In this
case, discharge and wash the system and
refill clean hydraulic oil.
4. Other hydraulic oil may not contain the
specified additive or may have different
viscosity. Therefore, please do not mix
products of different brands or of
different types. It is recommended to use
quality mineral oil with viscosity suitable
for operation environment of the
machine.
Note: metal particles may occur inside
hydraulic oil or filter of the new machine due
to wear of screen.
Hydraulic Oil
1. Please refer to recommended viscosity
scope in Chapter 1.
2. SINOBOOM recommends that SAE
viscosity be of 32 or 46.
3. In addition to the above, the only
