How to connect throttle pipe and trachea in Pu Sang?

1. First, fix the four screws of the accelerator. You can twist them by hand first, because hands are sensitive. Avoid twisting the screw directly with the sleeve. After manual tightening, it can be tightened with tools. Then, plug in the power. It takes a little effort to install the plug. Just one click indicates that the throttle is fixed.

2. Secondly, install the hose. There are two grooves on both sides of the hose, and people should aim at one large and one small convex groove on both sides.

3. Finally, fully insert the hose into both ends. When the convex and concave ends are completely consistent, touch the bottom of the hose by hand to ensure that the lower part is completely inserted, tighten the screws on the iron hoop, install the engine cover plate and install the throttle valve.
