First test whether the control mechanisms of the roller are flexible, and whether the forward and reverse driving, steering, accelerator and brake actions are normal.

Before starting the engine, the steering lock should be disengaged, the handbrake should be applied (open before starting), and the reversing lever and amplitude selector switch should be in the neutral position.

After the engine is started, pay attention to check whether the readings of the various instruments are normal, listen to the engine for abnormal noise, smell the engine for abnormal smell, and see if the engine has signs of illness. If any abnormality is found, turn off the engine immediately.

Before the road roller is put into operation, release the hand brake, carefully check and adjust whether the steering, braking and various control components are normal and flexible.

Before the road roller moves forward or reverses, check carefully that there are no obstacles in the front, rear, left and right of the vehicle body, and the locomotive should sound the warning first.
