When working in certain sections and the altitude exceeds the design value, the load should be reduced, the black smoke emission should be improved, the exhaust gas temperature should be reduced, and the reliability should be be assured.
When starting the engine in the cold season, do not continue to start for too long (up to 30 seconds) to avoid damage to the battery and starter.
Heating the battery (up to 58°C) during the cold season is beneficial for normal charging and discharging.
During the cold season, do not run the engine under heavy load immediately after starting to avoid engine damage. Pay attention to the normal operation of oil pressure and water temperature before increasing the load.
When stopping under high load conditions, it should be stopped after 2-3 minutes of no-load or idling operation, otherwise iIt is easy to damage the compressor and cause the piston to pull on the cylinder.
In summer, as long as it doesn't involve wastewater. Basically add fresh water. It is best to add antifreeze in winter. If you add water, remember to empty the water into the water tank and body once the water temperature drops below 60° after stopping the machine. Drain both places. There is a water release switch under the water tank and next to the machine body. Diesel is used for engine oil, 40% for new cars in summer, 50% for old cars and for winter engine oil in winter. The height of the engine oil should not be lower than the engraved line, nor higher than the upper engraved line. For specific maintenance, please read the instructions in detail, how often to change the engine oil and how often to change the filter element (including the filter element).nt oil filter, diesel filter element and air filter element)
