4 - OPERATING INSTRUCTIONS
Bringing the machine up to operating temperature
Before starting operation, allow the main systems to warm up to their normal operating temperature.
NOTE: the normal operating temperature for the hydraulic fluid is 50 – 80 °C ( 122 – 176 °F ).
NOTICE: do not operate the machine if the temperature of the hydraulic fluid is below 25 °C ( 77 °F ).
The warm-up procedure is necessary for proper and safe machine usage. Proper warm-up allows for the best possible
machine performance and fuel efficiency.
NOTICE: the warm-up of the machine is mandatory when operating in severe winter climates.
NOTICE: the warm-up of the machine prevents wear and severe damages to the engine, to the fuel system, and to
the hydraulic system.
NOTICE: the exhaust pipe becomes extremely hot while the engine is idling. Make sure that there is no flammable
material such as plants, dried grass, paper waste, oil and old tires close to the exhaust pipe before starting warm-up
procedure.
NOTICE: never cover the grids of the radiators with flammable materials.
1. Start the engine and let it run for approximately 5 – 10 min with no load.
2. Set the engine speed lever to mid-range speed.
3. Set the safety lock lever to UNLOCK position (frontward position).
4. Operate the bucket control lever for 5 min .
NOTICE: do not operate any control lever except the bucket control lever.
5. Set the engine speed lever to high speed.
6. Operate the bucket control lever and the arm lever for approximately 5 – 10 min with no load.
NOTICE: operate only the bucket control lever and the arm control lever.
7. Complete the warm-up procedure by operating the controls for all cylinders, travel, and swing for 3 to 4 times to
circulate warmed hydraulic fluid into the whole circuit.
Check the following items after reaching normal operating temperature of the fluids:
• Exhaust gas is normal.
• No unusual noise or vibration.
• No leak of oil, fuel or water.
• No unusual noise when activating the hydraulic equipment.
• Inspection of the horn, buzzer, working light, and instrument cluster.
• Proper display of the engine coolant temperature gauge.
• Check the visibility from the view mirrors before operation. Adjust and clean up dirt as necessary.
• Check each operation (travel, front equipment, and swing).
If any of the following occurs during the warm-up procedure, stop the engine immediately.
• Engine speed increases or decreases rapidly.
• Engine sound and exhaust gas color are abnormal.
• The display screen displays any message and warning sound beeps.
