Fire Hazards for Fuel, Oil and Hydraulic
Oil
If fuel, oil and anti-freeze fluid are put close to the fire source, it
is easy to cause fire. In particular, the fuel may cause extreme
danger.
Pay strictly attention to the following conditions:
Make sure the premises are well ventilated when the fuel, oil,
anti-freeze-fluid and hydraulic oil are filled in. Switch off the
lamp, control lever and the starter switch after the machine
is shut off. Shut off the engine. The equipment should be far
away from the flame and heating element. The auxiliary heating
element or the equipment which may cause sparks must be
quenched, switched off and move away from the loader.
Static can produce electric sparks at the oil filler. When it is cold
or dry, or in other conditions which easily cause the static, it is
necessary to make the oil filler always contact with the oil-filling
pipe, so as to guarantee a good grounding.
The covers for fuel tank and other liquid tanks shall be
tightened. Strictly prohibit from starting the equipment before
tightening.

Temperature
When the operation has just been stopped, the temperature of
coolant, engine oil and hydraulic oil is very high, and there is still
pressure in Radiator and hydraulic tank. In this case, opening
the cover to drain the oil or the coolant, or replacing the filtration
element will cause burns. It is necessary to wait for the tem-
perature to go down and perform the operation according to the
specified procedures.
In order to prevent the splashing of HT coolant and oil, it is
necessary to shut off the engine, and wait for cooling of coolant
oil, then slowly loosen the cover to release the pressure.
