replacement procedures are as follows:
1. Park the machine on the flat ground, and set the speed shifting handle in neutral gear
shift, rotate the button of the parking brake to reset, and put on a fixed frame rod, to
prevent the car from moving and rotating.
2. Start the engine and run it at idle speed, when the engine oil temperature reaches its
operating temperature (about 80
℃
~ 90
℃
), the engine turns off.
3. Drain out the oil by unscrewing the oil outlet screw piston at the bottom of the gear
