Maintenance of mini excavators and mini excavators

Generally speaking, the purpose of regular maintenance of small excavators is to reduce machine failures and prolong machine life; shorten machine downtime; in order to improve work efficiency and reduce operating costs, as long as the time and items specified in the manufacturer’s maintenance manual are used for small excavators The daily maintenance of the hydraulic system, engine and various motors of the small excavator can reduce the failure rate of the small excavator by 81%. This article will introduce the small maintenance of excavators and the maintenance items of small excavators in detail, hoping to help everyone.

Maintenance of mini excavators

1. When cleaning the inside of the cooling system, after the engine is completely cooled, slowly loosen the water injection cap, release the internal pressure of the water tank, and then discharge the water; do not clean the engine when it is working, because the high-speed rotating fan will cause danger. When cleaning or changing coolant, park the machine on level ground and replace the coolant and corrosion inhibitor.

2. Boom cylinder head pin; boom pin; boom cylinder rod end; bucket cylinder head pin; connecting pin of boom and stick; rod end of bucket cylinder; bucket cylinder head pin; half rod connecting rod connecting pin; bucket rod end and bucket cylinder; bucket cylinder head pin; stick connecting rod connecting pin; check the oil level in the slewing mechanism box (refuel);

3. Run at idle speed before turning off the engine. When the cooling water temperature drops below 60 and the water is not hot, turn off the flame and drain the water. If the cooling water is discharged prematurely, the body will suddenly shrink and crack when it is suddenly attacked by the high temperature and cold air. When draining, the remaining water in the body should be completely discharged to avoid freezing and swelling, causing the body to burst;

4. The low temperature in winter makes the diesel oil have poor fluidity, increased viscosity, and is not easy to spray, resulting in poor atomization and poor combustion, resulting in a decline in diesel engine power and economic performance. Therefore, light diesel oil with low freezing point and good ignition performance should be used in winter. It is generally required that the freezing point of the diesel engine is 7-13 degrees lower than the local minimum temperature of the season.

I believe that everyone has some understanding of “small excavator maintenance, small excavator maintenance”. It is a very common phenomenon that a mini excavator fails to start, and it usually occurs after the mini excavator has stopped working for a few days or more. In this case, the main reason why it won’t hit the car is long-term storage. Having some basic knowledge of daily maintenance can be very convenient in the operation of the small excavator. I hope everyone has to help.
