the bottom branch pipe or drain port;
6) Check the inside of the water tank.
If there is rust scale, increase the
solvent concentration to 8%, and
repeat the steps above;
7) After de-rusting, the acid solvent
can be neutralized by the following
methods: filling fresh water into the
mixing container, heating the mixture
to boiling point, and adding ordinary
soda as per the ratio: 0.5 kg soda with
20 l of water. Fill the solvent into the
radiator tank and then drain it back
into the container.
8) Flush the radiator tank several
times in this way, and finally let the
radiator tank be full of solvent for at
least one hour, then drain the internal
solvent and flush the radiator tank with
fresh hot water.
9) When the radiator is used again,
fill water into the tank, and test the
pressure in twice the working hydraulic
pressure. Carefully check for any
leakage caused by rust layer.
10) Before re-commissioning, the
coolant must be mixed with necessary
anti-rust and anti-corrosion agents or
antifreeze of proper proportion.
Air filter
The air filter is a device for removing
particulate impurities in the air. When
the diesel engine is working, if dust and
other impurities are contained in the
suction air, the wear of the parts will be
aggravated, so the air filter must be
installed. The air filter consists of filter
element and housing. The main
requirements for air filters are high
filtering efficiency, low flow resistance,
and long-term continuous use without
maintenance.
The air filter is equipped with a
resistance indicator to indicate the
blockage of the filter element. Before
each startup and operation of the set,
the resistance indicator shall be
checked, and the air filter shall be
replaced immediately when all red
signs can be seen from the window.
The replaced air filter shall be scrapped
and cannot be reused.
Caution! The filter element must be
replaced in time if it is damaged or the
intake resistance reaches the specified
pressure drop. No part that may be
loose is allowed in the intake duct in
front of the turbocharger; otherwise, it
will enter the turbocharger to damage
the impeller.
Battery
1. Precautions for correct use and
maintenance of battery
1) Check whether the bolts fixing the
battery on the bracket are tightened. If
the bolts are not tightened reliably, the
case will be damaged due to running
vibration. In addition, do not put any
metal object on the battery to prevent
short circuit.
2) Always check whether the poles
and connection terminals are reliably
connected. To prevent oxidation of the
terminals, protective agent such as
Vaseline can be applied.
3) Do not check the battery SOC with
