2. Technical Maintenance Contents
In order to ensure the engine operates properly,
technical maintenance should be carried out in the
following procedure:
2.1 Daily technical maintenance
(1) Inspect for the diesel fuel, coolant and oil level (see
Fig. 2-8-2), and add oil in accordance with technical
requirements if necessary.
Attention:
correct inspection for various fluid levels
can only be carried out when the diesel engine is
stopped.
Fig. 2-8-2 Choosing fuel (vehicle diesel) in
accordance with the ambient temperature
Diesel specification: use the diesel which complies with
CBl9147-2009 provision, for south areas in winter (warm
zone)
——10# or 20#, for north areas (cold zone)
——35#.
For the areas with environment requirements, use the
diesel complying with environmental regulations.
Choose fuel in accordance with the season and local
temperature. See Fig. 2-8-2.
Attention:
Never fill the fuel tank when the diesel
engine is running. If the vehicle is running in the hot
climate, the fuel tank should not be fully filled, or else the
fuel will overflow due to fuel extension; wipe the fuel as
soon as it overflows.
Inspect, add coolant.
Inspect the oil level.
Fig. 2-8-3 Checking the battery electrolyte
level
(2) Remove ash and electrolyte spilled on the battery to
make sure the vent hole unblocked. In normal conditions,
the battery almost needs no maintenance, but it needs to
be inspected regularly in high temperature conditions.
The fluid level should be between the Min. and Max.
marks on the side surface. The storage battery should be
filled with distilled water when the electrolyte is not
enough.
Caution:
Never fill the battery with additional fluid
and other impure water optionally, or else it will cause
insufficient charging and affect usage. If the fluid level
drops fast, the storage battery should be sent to the
service station for repair.
Warning:
the electrolyte is corrosive and must not
be splashed in eyes, on skin and clothes; clean it with
fresh water immediately if it is splashed on above
mentioned places.
