With the development of highways and the needs of road machinery, road rollers, as a type of compaction machinery, have played a role that cannot be ignored. But improper operation will lead to inevitable consequences. This article will take you to learn together.
Make sure that the throttle handle of the diesel engine is in the medium speed position (after the roller starts, it will be back to the high speed). Depress the clutch pedal to cut off power. Push or pull the handle backwards in the direction of walking. Determine the driving speed of the roller according to the needs. Pull the gear lever to the required gear. The first gear is the working efficiency, the second gear is the working and transportation speed, and the third gear is the transportation speed. Lower the wrench to brake. Release the clutch pedal. The following explains the precautions for operating the roller.
The roller is walking forward or backward. At this time, you should first test whether the foot brake is sensitive. Note: When stepping on the foot brake, it is not possible to use excessive force, so be careful not to forget to step on the clutch first. Turn the steering wheel to try it on the spot, whether the hydraulic steering gear is effective and reliable. Pull the engine throttle handle back to make the engine reach full speed.
Note: When shifting or reversing, the roller must first reduce the engine speed to reduce the speed of the roller; when shifting or reversing, the main clutch must be stepped on, otherwise the gears will wear or break early. Then gently push or shift lightly or reverse the handle until the gears are fully engaged. When operating the inverted handle, move smoothly and quickly, and do not use excessive force. First put it in the middle position and stop for a period of time (about 10 seconds) to reduce the inertia of the roller forward or backward, then pull the reverse handle and make it in place to ensure that the gears are fully engaged. When going uphill and downhill, the speed of first gear should be used for driving. The shifting should be carried out before going uphill or downhill. Emergency braking: Depress the clutch pedal. When using the foot brake, do not use too much force, in case of emergency, you can apply the hand brake at the same time. Try to avoid implementing emergency braking at high speed of the roller, otherwise it will reduce the service life of the brake system.
Notes on the operation of the roller-the steering of the roller
Turn on the left turn signal or turn on the right turn signal switch, the corresponding turn signal lights.
When the driving speed of the roller is high gear (third gear), the throttle handle should be operated to reduce the driving speed of the roller.
Turn the steering wheel to the left (or right) to change the roller.
Note: Be careful in steering operations to prevent the rear wheels of the roller from driving out of the roadbed or crushing the road curb.
Cautions for operating the roller-parking
Move the throttle handle to the middle speed position to reduce the speed of the roller. Step on the clutch pedal, put the inverted handle in the neutral position, put the shift lever in neutral, and release the clutch pedal. Pull up the hand brake. Gradually reduce the engine speed and run at idle speed for 3-5 minutes to reduce the engine temperature. Then pull up the flameout door and turn off the engine. Turn the ignition switch counterclockwise to the original position to cut off the circuit. Turn off the power switch.
