Q&A
How to check the hydraulic oil level?
Park the excavator on a flat ground, turn off the engine and wait for a while, then check the hydraulic oil level through the oil level gauge of the hydraulic oil tank.
What liquid should be added to the battery (battery) used normally in the excavator after the liquid level drops? Why?
Distilled water should be added. Because the battery will generate heat during the charging and discharging process, the water will evaporate, and the specific gravity of the electrolyte will increase. After adding distilled water, the specific gravity of the electrolyte can be restored.
How to ensure the excavator starts normally after long-term storage?
Before long-term storage, perform a thorough inspection and maintenance, drain fuel and hydraulic oil, lubricate all parts, start the engine periodically to run the system, and ensure all systems operate correctly.
Which oil level is the most suitable for the oil cylinder?
There are usually the highest and lowest oil level marks (MAX and MIN) on the inner wall of the oil filling port of each engine. This means that the oil level cannot exceed MAX or be lower than MIN.
A lower oil level, that is, a decrease in the amount of oil in the engine, will increase the oil load, causing the oil to become more seriously contaminated by heat, which not only weakens the lubrication performance, but also increases the fuel consumption. Because the less oil in the engine, the higher the oil temperature; and the higher the oil temperature, the greater the fuel consumption will be as the oil temperature rises. It is very dangerous to run the engine when the oil level is at the lowest point (MIN).
Keeping the oil level at the highest point (MAX) all the time will cause the oil to foam and lead to insufficient lubrication, resulting in serious wear. Foaming oil will also increase fuel consumption.
Therefore, it is recommended to keep the engine oil level between the MAX and MIN marks at a position close to one-third of the MAX.
