Checking and Adjustment of Engine Valve Clearance
These operations require experiences. Please ask your sales or service dealer for operations.
Cleaning of Engine Cooling System
Please stop the engine and wait for the machine to cool down before maintenance.
The engine coolant is also under high temperature and high pressure after operation. Take
special caution while loosening the cap or plug. Operating the machine in such case may cause
scalding and injuries by splashing high temperature coolant.
If the maintenance requires the running of engine, assign two operators for teamwork and keep
contact with each other. One operator must sit in the driver seat to get ready to stop the engine
immediately when necessary. This operator must pay special attention not to touch any joystick
or pedal, unless it’s absolutely necessary. The other operator for the maintenance must keep the
body and clothing away from motion parts of machine. While the engine is running, it’s really
dangerous standing behind the machine, as the machine probably moves suddenly. While the
engine is running, never stand behind the machine.
Do not disassemble the radiator cap or drainage plug when the coolant is hot.
Stop the engine, wait for the engine and radiator to cool down, and then slowly loosen and take
out the radiator cap and drainage plug.
During cleaning, if the coolant temperature is low, the thermostat will be closed, and the coolant
will not flow within the radiator. Before cleaning, heat up the coolant to at least 90℃.
Open the engine hood.
Slowly loosen the radiator cap (3) to relieve the internal
pressure and then take out the cap.
Place a tray beneath the water drainage plug (4) to
collect the used coolant and then loosen the water
drainage plug (4) to drain the coolant.
Tighten the water drainage plug (4).
Add running water through the water filler port into
the radiator, till the water level reaches the top of filler
port. Add the water slowly and easily to prevent the
ingress of air into radiator.
Install the radiator cap (3).
Start the engine and run the engine at a speed slightly
higher than the low idling speed. Heat up the water
temperature to at least 90℃, open the thermostat, and
then run the engine for approximately 10min.
