water in the engine, the oil and water in the radiator may be still very high after just finishing the
work. Wait for the temperature falling down and follow the procedures to do the operations
above.
z
To avoid hot water ejecting from the radiator, stop the engine, let the hot water cool, and open the
cover slowly to release the pressure. Never touch the radiator. Check the air temperature in front
of the radiator to gauge the temperature.

To avoid hot oil ejecting from the radiator, stop the engine, let the hot water cool, and open the
cover slowly to release the pressure. Never touch the radiator. Check the air temperature in front
of the radiator to gauge the temperature.
z
While the machine is warming-up, do not touch engine, silencer, tail pipe or relay to prevent
burn.
z
While the machine is warming-up, do not disassemble the water heat sensor of the engine, oil
heat sensor of the torque converter or the water pipe of air condition to prevent burn.
z
Never
let the harmful alkaline materials in the coolant system touch your skin or eyes.
z
Choose a proper container to hold the liquid when replacing the coolant, mobile oil of the engine,
oil of the transmission box and cleaning the parts.
Please refer to
8.20 Waste Materials
in this
chapter for the methods to deal with the waste liquid.
z
Keep fire off when disassembling the connection
pipe of the air condition compressor.
8.12 Examination and Repair of Hydraulic System
z
Lock the oil tank and other hydraulic equipment safely; release the pressure of all hydraulic
systems before examining the hydraulic system.
z
Never
bend or beat the high pressure hydraulic pipe.
Never
assemble the hard pipe and soft pipe
if they are bent abnormally or broken.
z
Routinely repair any loose or broken fuel oil circuits, lubricating oil circuits, the hard and soft
pipe of the hydraulic system. Leakage can cause fire, so routine maintenance is critical.
z
Examine the pipe system carefully (hard pipe and soft pipe), screw down the connectors
according to the proper torque. Do not examine a leak using your hand, rather use a board or
paper board. The leaking hydraulic liquid may penetrate your skin and cause death. If the liquid
splash onto your skin, the case of a physician trained for this kind of “burn” will be immediately
