Gear operation of heavy truck in Ou Man

When the automatic gear starts, you should step on the brakes to prevent the car from slipping or moving forward. If you want to shift gears when driving after starting, you should reduce the speed to the corresponding speed and then shift gears directly.

For example, when you step on the brake, put the handbrake in the D position and start driving normally, you need to downshift to the S(2, D2) position because of road problems. Since D gear will automatically change from L gear to direct gear, when you release the throttle to slow down the speed corresponding to S gear, just press the gear lock and pull the gear lever to change to S gear.

Be careful not to shift to low gear at high speed, and be sure to slow down before shifting gears; When changing into reverse gear, be sure to stop the car completely before changing into reverse gear.
