 Note:

Before starting the engine, do as much oil refilling procedure as possible to reduce the chance of air entering 

the hydraulic tappet

If there is still air in and noise occurs, follow the exhaust procedure to eliminate the noise


How to remove air:

1. There is noise after starting the engine, the engine speed should be kept at 2000-3000 rpm, continuous 

running for minutes

2. Then let the engine idle for 30 seconds

3. After the above steps, most of the noise can be eliminated. If there is still noise, the above working 

procedure can be repeated.

4. If repeating the above operation 6 times still does not solve the problem, please contact us
