If you decide to buy equipment at a low price, make sure that you communicate with the real seller. Find out as much information about the owner of the equipment as possible. One way of cheating is to represent yourself as a real company. In case of suspicion, inform us about this for additional control, through the feedback form.
Before you decide to make a purchase, carefully review several sales offers to understand the average cost of your chosen equipment. If the price of the offer you like is much lower than similar offers, think about it. A significant price difference may indicate hidden defects or an attempt by the seller to commit fraudulent acts.
Do not buy products which price is too different from the average price for similar equipment.
Do not give consent to dubious pledges and prepaid goods. In case of doubt, do not be afraid to clarify details, ask for additional photographs and documents for equipment, check the authenticity of documents, ask questions.
The most common type of fraud. Unfair sellers may request a certain amount of advance payment to “book” your right to purchase equipment. Thus, fraudsters can collect a large amount and disappear, no longer get in touch.
- Transfer of prepayment to the card
- Do not make an advance payment without paperwork confirming the process of transferring money, if during the communication the seller is in doubt.
- Transfer to the “Trustee” account
- Such a request should be alarming, most likely you are communicating with a fraudster.
- Transfer to a company account with a similar name
- Be careful, fraudsters may disguise themselves as well-known companies, making minor changes to the name. Do not transfer funds if the company name is in doubt.
- Substitution of own details in the invoice of a real company
- Before making a transfer, make sure that the specified details are correct, and whether they relate to the specified company.

The excavator hydraulic pump is the "power core" of the excavator's hydraulic system. Its core function is to convert the engine's mechanical energy into hydraulic energy, supplying pressure oil for operations such as digging, rotating, and lifting. Its usage should focus on three cores: proper operation, daily maintenance, and fault prediction to ensure stable system operation.
1,Warm up after startup: After starting the engine, let it idle for 3-5 minutes. Only operate when the hydraulic oil temperature rises above 20℃. Avoid sudden acceleration or rapid action switching when the machine is cold to prevent pump wear due to insufficient lubrication.
2,Smooth operation: Push the control lever slowly and avoid sudden load increases. For example, do not force digging in hard soil, and do not perform rapid rotation and boom lifting simultaneously to reduce instantaneous pressure impact on the pump.
3,Avoid long-term high-pressure idling: Do not run the pump under high pressure (e.g., full bucket suspended, digging stuck on hard rock) for more than 30 seconds. If the time is exceeded, relieve pressure first (e.g., retract the bucket, lower the boom) to prevent pump overheating and damage.
