What to do before operating a mini excavator?

1. Check fluid levels
Hydraulic Fluid: Check the level and quality of the hydraulic fluid. Proper operation of the hydraulic system depends on adequate and clean hydraulic fluid. If the level is too low or the fluid is deteriorating, it needs to be added or replaced promptly.
Engine oil: Check the level and quality of engine oil to ensure that the engine can work properly.
Coolant: Check the coolant level to ensure that the engine will not be damaged due to overheating.
Fuel: Make sure there is enough fuel in the tank to avoid stopping the engine due to insufficient fuel during the working process.

2. Check the hydraulic system
Check all hydraulic pipes and fittings for leaks. Leaks can lead to insufficient system pressure and affect the efficiency and safety of the excavator.
Make sure the hydraulic filter is clean and not clogged. If the filter element is dirty, it should be cleaned or replaced.

3. Checking the tracks and travel system
Track Tension: Check the tension of the tracks to make sure they are not too loose or too tight. Loose tracks can cause erratic travel, while tight tracks can increase wear.
Check track wear: Check tracks for damage, cracks or excessive wear and replace or repair damaged parts.
Wheel axle and steering system: Make sure the steering system and wheel axle are free of abnormalities and running smoothly.

4. Bucket and boom inspection
Bucket Inspection: Check that the bucket is securely attached and that there are no cracks or other damage to the bucket. Make sure the working surface of the bucket is not excessively worn.
Boom Check: Check the hydraulic boom for proper function and make sure it extends and retracts smoothly.
Bucket operating system: Make sure the hydraulic control system is working properly and the operating lever can precisely control the bucket's movement.

5. Checking the battery and electrical system
Check the battery level and make sure it is sufficient. If the battery is too low, recharge or replace it.
Check wires and connectors for loose, frayed or corroded wires and connectors to avoid operating problems caused by electrical malfunctions.

6. Checking the control system
Control Lever Check: Ensure that the operating control lever is flexible, free of jams, and responds accurately when operated.
Instrument panel check: Check all indicator lights and displays on the instrument panel to ensure that no malfunction warning lights are illuminated.

7. Checking safety facilities
Safety belts: Ensure that operators wear safety belts, especially when working at height.
Protective equipment: Operators should wear safety clothing, work shoes, gloves and other necessary protective equipment.
Surrounding safety inspection: Check the work area for obstacles or potential sources of danger to ensure that the work area is safe.

8. Checking the environment and the ground
Operating site: Check that the ground is level to avoid operating on unstable ground.
Obstacle check: Ensure that there are no large obstacles (e.g. rocks, steel bars, etc.) in the work area to avoid injury to the machine or operator.
Safety Distance: Ensure that the operator keeps a safe distance from other people, especially when moving or rotating.

9. Adjustment of work modes
Adjust the settings of the excavator by selecting the appropriate work mode (e.g., digging, leveling, lifting, etc. mode) according to the requirements of the work task and the site.

10. Warming up the engine
In cold weather, start the engine and let it idle for a few minutes to help warm up the hydraulic system and engine to ensure the machine works properly.

Summarize
Carrying out the above checks and preparations can effectively minimize excavator breakdowns, improve work efficiency and ensure safe operation. Before starting operation, it is important to ensure that all systems are working properly and that the operating environment is safe. This will not only ensure the successful completion of the task, but also extend the life of the excavator.
