Take Care
💡
Small details to prevent you from spending money in vain
- 1 Before each refueling, the oil pump, oil can and other containers and tools must be cleaned and wiped.
- 2 Before changing the oil, the machinery must be thoroughly rinsed with a solvent. Water-soluble cleaning agents must not be used.
- 3 After each addition or replacement of lubricating oil, keep a record of mechanical maintenance.
- 4 Replace the filter element at the same time as each oil change.
- 5 Keep the fuel tank sealed to prevent the entry of flying dust and moisture.
⚠ Attention:
Specialized oil pumps must be used for various types, especially for pure oil and water-based coolant. Mixing oil pumps is extremely avoided, as it may cause corrosion and increased wear of metal parts in the equipment lubrication system. Cutting fluid mixed with miscellaneous oil can easily breed bacteria and shorten the service life.
Frequently Asked Questions
Q
Is this cutting fluid safe for operators and the environment?
Yes. The cutting fluid is non-toxic and harmless, and fully complies with environmental protection standards, making it safe for daily use by machine operators.
Q
What is the recommended dilution ratio for the emulsion?
Based on the typical data, a 5% dilution is used for pH testing and a 3% dilution is used for rust resistance testing. The appropriate ratio for your application may vary — consult the product datasheet or your supplier for guidance.
Q
How does this product protect against rust?
The fluid provides dual rust prevention and passivation effects through its film-forming properties. At a 3% concentration, iron filings show no rust, demonstrating strong corrosion protection performance.
Q
Can I use the same oil pump for both pure oil and water-based coolant?
No. Mixing oil pumps between pure oil and water-based coolant is strongly discouraged. Doing so can cause corrosion, increased wear on metal parts, and may allow bacteria to breed in the cutting fluid, significantly shortening its service life.
Q
How often should the filter element and cutting fluid be replaced?
The filter element should be replaced every time the cutting fluid is changed. Always keep a maintenance record after each oil addition or replacement to track service intervals accurately.
Q
What precautions should be taken when storing the cutting fluid?
Keep the fuel tank sealed at all times to prevent contamination from airborne dust and moisture. Before refueling, ensure all containers, oil pumps, and tools are thoroughly cleaned to avoid cross-contamination.
