FAQ

1. What is the core function of 800901338 air booster pump?
It uses compressed air to assist the hydraulic braking system, greatly reducing the operator’s pedaling force while increasing braking output, ensuring efficient and reliable braking.
2. What advantages make it suitable for roller working conditions?
It has high-strength shell, wear-resistant internal piston and good anti-vibration performance. It can work stably under long-term vibration and dusty construction environment.
3. Can this air booster pump be installed directly?
Yes. The mounting bracket, air inlet, oil port and connection size are all designed to original factory standards, supporting direct installation without modification.
4. What faults will be caused by a damaged or failing booster pump?
It will result in heavy brake pedal, weak braking force, slow response, air or oil leakage, and even insufficient braking, which seriously affects driving safety.
5. When should the air booster pump be replaced?
Replacement is required when obvious air leakage or oil leakage appears, braking becomes heavy, internal abnormal sound occurs, or the assistance function completely fails.
6. How does this booster pump improve operating comfort?
It provides obvious power assistance, making braking operation light and labor-saving, reducing fatigue during long-time construction and improving control stability.
7. What daily maintenance helps extend its service life?
Keep the air circuit dry and clean, check for air and oil leakage regularly, maintain proper air pressure, and avoid long-term rust and corrosion.
