Warranty

1. One-year machine warrant starts from the date of machine delivery. For any machine breakdown under normal use conditions within warranty period, we will be responsible for free maintenance; if the machine breakdown is due to improper human operation and there is a need to replace certain components, then certain fee shall be charged.
2. We will still be responsible for maintenance beyond warranty period, but associated fee will be charged. If any component placement occurred, there would be one-year warranty for that component, too.
3. Corrosive oil products cannot be applied to BYJ Precision Oil Filtration System. We will not be responsible for damage caused by the use of corrosive oil.
4. The consumables such as filter core and filtering mesh are not covered by warranty.

NAS Grade

The generally accepted standard for quality of oil products, which is based on the particle sizes and numbers contained in 100 liter oil.

From changes in the appearance of filter core we can judge the conditions of hydraulic machines

Through observations of the overall shapes and types of pollutants that adhere to the filter core surfaces, we can estimate the mechanical damage and the state of rotary axis, so that machine accidents could be prevented.
